Zhou T, Salman D, McGregor A, 2024, mHealth Apps for the Self-Management of Low Back Pain: Systematic Search in App Stores and Content Analysis., JMIR Mhealth Uhealth, Vol: 12
BACKGROUND: With the rapid development of mobile health (mHealth) technology, many health apps have been introduced to the commercial market for people with back pain conditions. However, little is known about their content, quality, approaches to care for low back pain (LBP), and associated risks of use. OBJECTIVE: The aims of this research were to (1) identify apps for the self-management of LBP currently on the market and (2) assess their quality, intervention content, theoretical approaches, and risk-related approaches. METHODS: The UK iTunes and Google Play stores were initially searched for apps related to the self-management of LBP in May 2022. A repeat search in June 2023 was conducted to ensure that any relevant new apps developed in the last year were incorporated into the review. A total of 3 keywords recommended by the Cochrane Back and Neck Group were used to search apps "low back pain," "back pain," and "lumbago." The quality of the apps was assessed by using the 5-point Mobile App Rating Scale (MARS). RESULTS: A total of 69 apps (25 iOS and 44 Android) met the inclusion criteria. These LBP self-management apps mainly provide recommendations on muscle stretching (n=51, 73.9%), muscle strengthening (n=42, 60.9%), core stability exercises (n=32, 46.4%), yoga (n=19, 27.5%), and information about LBP mechanisms (n=17, 24.6%). Most interventions (n=14, 78%) are consistent with the recommendations in the National Institute for Health and Care Excellence (NICE) guidelines. The mean (SD) MARS overall score of included apps was 2.4 (0.44) out of a possible 5 points. The functionality dimension was associated with the highest score (3.0), whereas the engagement and information dimension resulted in the lowest score (2.1). Regarding theoretical and risk-related approaches, 18 (26.1%) of the 69 apps reported the rate of intervention progression, 11 (15.9%) reported safety checks, only 1 (1.4%) reported personalization of care, and non
Clunie G, Roe J, Al-Yaghchi C, et al., 2024, The voice and swallowing profile of adults with laryngotracheal stenosis before and after reconstructive surgery: a prospective, descriptive observational study, Clinical Otolaryngology, ISSN: 0307-7772
Objectives:Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery.Design:Outcome measures were collected pre-reconstructive surgery, two-weeks post-surgery and up to 4-6 months post-surgery.Setting:Tertiary referral centre.Participants:With ethical approval, twenty consecutive adult (≥18 years) LTS patients undergoing airway reconstruction were prospectively recruited.Main outcome measures:These included physiological values (maximum phonation time (MPT) and fundamental frequency; penetration aspiration score, residue score), clinician-reported (GRBAS, functional oral intake score, 100ml Water Swallow Test) and patient-reported outcomes (Voice Handicap Index-10, Reflux Symptoms Index, Eating Assessment Tool, Dysphagia Handicap Index).Results:The observational study identified patient-reported and clinician-reported voice and swallow difficulties pre- and post-surgery; median and interquartile range are reported at each time point: Voice Handicap Index-10 23 (8-31); 20.5 (9-33.5), 24.5 (12.5-29); Dysphagia Handicap Index 9 (0-37); 13 (7-44); 15 (4-34); GRBAS grade 1(1-2); 2 (1-2.5); 2(1-2); 100ml Water Swallow Test volume score 16.7 (11.1-20); 14.3 (12.5-16.7); 16.7 (14.3-20.0); 100ml Water Swallow Test capacity score 16.3 ± 9.0; 11.0 ± 4.1; 12.5 ± 2.6.Conclusions:We present the first prospective data on voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. The variability of the outcomes was higher than expected but importantly, for many the voice and swallow outcomes were not within normal limits before surgery. The clinical value of the study demonstrates the need for individual assessment and management of LTS patients’ voice and swallowing.
Liu S, Amiri P, McGregor A, et al., 2023, Bilateral asymmetry in knee and hip musculoskeletal loading during stair ascending/descending in individuals with unilateral mild to moderate medial knee osteoarthritis, Annals of Biomedical Engineering, Vol: 51, Pages: 2490-2503, ISSN: 0090-6964
Most cases of unilateral knee osteoarthritis (OA) progress to bilateral OA within 10 years. Biomechanical asymmetries have been implicated in contralateral OA development; however, gait analysis alone does not consistently detect asymmetries in OA patient gait. Stair ambulation is a more demanding activity that may be more suited to reveal between-leg asymmetries in OA patients. The objective of this study was to investigate the between-leg biomechanical differences in patients with unilateral mild-to-moderate knee OA. Sixteen unilateral mild-to-moderate medial knee OA patients and 16 healthy individuals underwent kinematic and kinetic analysis of stair ascent and descent. Stair ascent produced higher loading and muscle forces in the unaffected limb compared to the OA limb, and stair descent produced lower loading on the OA limb compared to healthy subjects. These biomechanical differences were apparent in the ankle, knee, and hip joints. The implications of these findings are that OA patients rely more heavily on their unaffected sides than the affected side in stair ascent, a strategy that may be detrimental to the unaffected joint health. The reduction in affected limb loading in stair descent is thought to be related to minimizing pain.
Green C, Beaney T, Salman D, et al., 2023, The impacts of social restrictions during the COVID-19 pandemic on the physical activity levels of over 50-year olds: The CHARIOT COVID-19 Rapid Response (CCRR) cohort study., PLoS One, Vol: 18, ISSN: 1932-6203
OBJECTIVES: To quantify the associations between shielding status and loneliness at the start of the COVID-19 pandemic, and physical activity (PA) levels throughout the pandemic. METHODS: Demographic, health and lifestyle characteristics of 7748 cognitively healthy adults aged >50, and living in London, were surveyed from April 2020 to March 2021. The International Physical Activity Questionnaire (IPAQ) short-form assessed PA before COVID-19 restrictions, and up to 6 times over 11 months. Linear mixed models investigated associations between shielding status and loneliness at the onset of the pandemic, with PA over time. RESULTS: Participants who felt 'often lonely' at the outset of the pandemic completed an average of 522 and 547 fewer Metabolic Equivalent of Task (MET) minutes/week during the pandemic (95% CI: -809, -236, p<0.001) (95% CI: -818, -275, p<0.001) than those who felt 'never lonely' in univariable and multivariable models adjusted for demographic factors respectively. Those who felt 'sometimes lonely' completed 112 fewer MET minutes/week (95% CI: -219, -5, p = 0.041) than those who felt 'never lonely' following adjustment for demographic factors. Participants who were shielding at the outset of the pandemic completed an average of 352 fewer MET minutes/week during the pandemic than those who were not (95% CI: -432, -273; p<0.001) in univariable models and 228 fewer MET minutes/week (95% CI: -307, -150, p<0.001) following adjustment for demographic factors. No significant associations were found after further adjustment for health and lifestyle factors. CONCLUSIONS: Those shielding or lonely at pandemic onset were likely to have completed low levels of PA during the pandemic. These associations are influenced by co-morbidities and health status.
McMenemy L, Behan FP, Kaufmann J, et al., 2023, Association between combat-related traumatic injury and skeletal health: bone mineral density loss is localized and correlates with altered loading in amputees: the Armed Services Trauma Rehabilitation Outcome (ADVANCE) Study, Journal of Bone and Mineral Research, Vol: 38, Pages: 1227-1233, ISSN: 0884-0431
The association between combat-related traumatic injury (CRTI) and bone health is uncertain. A disproportionate number of lower limb amputees from the Iraq and Afghanistan conflicts are diagnosed with osteopenia/osteoporosis, increasing lifetime risk of fragility fracture and challenging traditional osteoporosis treatment paradigms. The aim of this study is to test the hypotheses that CRTI results in a systemic reduction in bone mineral density (BMD) and that active traumatic lower limb amputees have localized BMD reduction, which is more prominent with higher level amputations. This is a cross-sectional analysis of the first phase of a cohort study comprising 575 male adult UK military personnel with CRTI (UK-Afghanistan War 2003 to 2014; including 153 lower limb amputees) who were frequency-matched to 562 uninjured men by age, service, rank, regiment, deployment period, and role-in-theatre. BMD was assessed using dual-energy X-ray absorptiometry (DXA) scanning of the hips and lumbar spine. Femoral neck BMD was lower in the CRTI than the uninjured group (T-score -0.08 versus -0.42 p = .000). Subgroup analysis revealed this reduction was significant only at the femoral neck of the amputated limb of amputees (p = 0.000), where the reduction was greater for above knee amputees than below knee amputees (p < 0.001). There were no differences in spine BMD or activity levels between amputees and controls. Changes in bone health in CRTI appear to be mechanically driven rather than systemic and are only evident in those with lower limb amputation. This may arise from altered joint and muscle loading creating a reduced mechanical stimulus to the femur resulting in localized unloading osteopenia. This suggests that interventions to stimulate bone may provide an effective management strategy. © 2023 Crown copyright and The Authors.

Cowell I, McGregor A, O'Sullivan P, et al., 2023, Physiotherapists' perceptions on using a multidimensional clinical reasoning form during psychologically informed training for low back pain, Musculoskeletal Science and Practice, Vol: 66, Pages: 1-7, ISSN: 2468-7812
PURPOSE: Building clinical reasoning skills is important to effectively implement psychologically informed practice. We developed a multidimensional clinical reasoning form (CRF) to be used by physiotherapists in a psychologically informed practice training programme for low back pain. In this paper we describe the development of the CRF, how the CRF was used in the training, and present an evaluation of physiotherapists' perceptions of the CRF. METHODS: Qualitative semi-structured interviews were conducted with ten physiotherapists purposively sampled in primary care. Data were gathered through pre, and post training focus group interviews and a secondary analysis of individual physiotherapist interviews conducted after the training. Thematic analysis was used to analyse the data and capture the emergent themes. RESULTS: Two main themes emerged before the training: (1) the CRF 'needs formal training' and (2) 'lacked instruction'. Three main themes emerged after the training (1) it provided 'a helpful framework for multidimensional clinical reasoning' (2) the CRF, and accompanying operational definitions, helped physiotherapists 'elicit information, with 'question prompts' helpful in facilitating patient disclosure (3) 'Utility' - although the CRF was not formally used by the physiotherapists it provided a conceptual reasoning framework to work from with more challenging patients. CONCLUSION: The CRF was not designed to be used in isolation by clinicians without training. However, when used as a training adjunct it appears to be valued by physiotherapists to help develop their critical thinking and better characterise patients' presentations in order to personalise care from a bio-psychosocial perspective.
Kent P, Haines T, O'Sullivan P, et al., 2023, Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain (RESTORE): a randomised, controlled, three-arm, parallel group, phase 3, clinical trial, The Lancet, Vol: 401, Pages: 1866-1877, ISSN: 0140-6736
BACKGROUND: Low back pain is the leading cause of years lived with disability globally, but most interventions have only short-lasting, small to moderate effects. Cognitive functional therapy (CFT) is an individualised approach that targets unhelpful pain-related cognitions, emotions, and behaviours that contribute to pain and disability. Movement sensor biofeedback might enhance treatment effects. We aimed to compare the effectiveness and economic efficiency of CFT, delivered with or without movement sensor biofeedback, with usual care for patients with chronic, disabling low back pain. METHODS: RESTORE was a randomised, controlled, three-arm, parallel group, phase 3 trial, done in 20 primary care physiotherapy clinics in Australia. We recruited adults (aged ≥18 years) with low back pain lasting more than 3 months with at least moderate pain-related physical activity limitation. Exclusion criteria were serious spinal pathology (eg, fracture, infection, or cancer), any medical condition that prevented being physically active, being pregnant or having given birth within the previous 3 months, inadequate English literacy for the study's questionnaires and instructions, a skin allergy to hypoallergenic tape adhesives, surgery scheduled within 3 months, or an unwillingness to travel to trial sites. Participants were randomly assigned (1:1:1) via a centralised adaptive schedule to usual care, CFT only, or CFT plus biofeedback. The primary clinical outcome was activity limitation at 13 weeks, self-reported by participants using the 24-point Roland Morris Disability Questionnaire. The primary economic outcome was quality-adjusted life-years (QALYs). Participants in both interventions received up to seven treatment sessions over 12 weeks plus a booster session at 26 weeks. Physiotherapists and patients were not masked. This trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12618001396213. FINDINGS: Between Oct 23, 2018 and Aug 3, 2020, we
Benton A, Amiri P, Henson DP, et al., 2023, Characterization of muscle recruitment during gait of bilateral transfemoral and through-knee persons with limb loss, Frontiers in Bioengineering and Biotechnology, Vol: 11, Pages: 1-10, ISSN: 2296-4185
Introduction: Due to loss in musculoskeletal capacity, there is an increased burden on the residual limbs of bilateral transfemoral and through-knee persons with limb loss. This reduced capacity is associated with an increased cost of walking that is detrimental to functionality. Compensatory gait strategies are adopted by this population. However, how these strategies relate to specific muscle recruitment is not known. The primary aim of this study is to characterize muscle recruitment during gait of this population. The secondary aim is to assess whether the measured kinematics can be actuated when the endurance of specific muscles is reduced and if this is the case, which alternative muscles facilitate this.Methods: 3D gait data and high-resolution magnetic resonance images were acquired from six bilateral transfemoral and through-knee persons with limb loss. Subject-specific anatomical muscle models were developed for each participant, and a validated musculoskeletal model was used to quantify muscle forces in two conditions: during normal gait (baseline) and when muscles, which were identified as functioning above a “healthy” level at baseline, have a reduced magnitude of maximum force capacity (reduced endurance simulation). To test the hypothesis that there are differences in muscle forces between the baseline trials and the simulations with reduced muscular endurance, a Bonferroni corrected two-way ANOVA with repeated measures was completed between the two states.Results: The baseline analysis showed that the hip flexors experience relatively high muscle activations during gait. The reduced endurance simulation found two scenarios. First, for 5 out of the 12 simulations, the baseline kinematics could not be reproduced with the reduced muscular capacity. Second, for 7 out of 12 cases where the baseline kinematics were achieved, this was possible with compensatory increased activation of some muscles with similar functions (p ≤ 0.003).Discussion

The perceived impact of a digital rehabilitation tool for returning to fitness following a period of illness, including Covid-19 infection: a qualitative study, BMJ Open Sport & Exercise Medicine, Vol: 9, Pages: 1-20, ISSN: 2055-7647
Digital interventions can increase physical activity (PA) levels in adults. However, the Covid-19 pandemic highlighted the complexities faced when guiding people to start, or return to, PA following illness or inactivity. A digital tool, Movement Foundations, was developed to provide remote guidance on building strength and capacity across functional movement patterns, with graduated progression based on user responses and input. This qualitative study aimed to explore the perceived impacts of using the tool. Nine participants aged over 35 years from the healthcare and academic healthcare sectors were recruited to use it and were subsequently interviewed. Thematic analysis identified three themes falling under the overarching concept of COM-B Plus (Capability, Opportunity and Motivation-Behaviour), encompassing: skills and capacity for movement; opportunities, motivations and barriers for movement; and a personalised, safe space in which to develop. Participants felt that the digital tool increased their capacity and confidence in movement and positively impacted their daily activities. External factors such as illness and stress clouded perceptions of the impacts of PA. Time, work pressures and needing equipment were still considered significant barriers to PA. Still, participants appreciated the flexibility and non-prescriptive nature of the tool and felt that it helped movement to become opportunistic and habitual. Increased capacity for PA and feeling the subsequent physical and mental effects positively influenced motivation. Structure and guidance, with graduated progress, were seen as protective. Guided self-reflection helped participants understand their capacity and limitations with regard to movement and promoted motivation. Although acquiring technical skills to guide movement may be important for those recovering from illness, participants found that a structure promoting individualised guidance, graduated progression and guided self-reflection were impo

Sham interventions in randomised clinical trials (RCTs) of physical, psychological, and self-management (PPS) therapies for pain are highly variable in design and thought to contribute to poor internal validity. It has, however, not been formally tested whether the extent to which sham controls resemble the treatment under investigation consistently affects trial outcomes, such as effect sizes, differential attrition, participant expectancy, and blinding effectiveness.Placebo or sham-controlled RCTs of PPS interventions of clinical pain populations were searched in twelve databases. The similarity of control interventions to the experimental treatment was rated across 25 features. Meta-regression analyses assessed putative links between employed control interventions, observed effect sizes in pain-related outcomes, attrition, and blinding success.The sample included 198 unique control interventions, dominated by manual therapy and chronic musculoskeletal pain research. Meta-analyses indicated small to moderate benefit of active treatments over control interventions, across subgroups of manual therapies, exercise, and rehabilitation, and psychological intervention trials. Multiple meta-regression modelling demonstrated that similarity between sham control and tested interventions predicted variability in pain-related outcomes, attrition, and blinding effectiveness. Influential were differences relating to the extent of intervention exposure, participant experience, and treatment environments.The results support the supposed link between blinding methods and effect sizes, based on a large and systematically sourced overview of methods. Challenges to effective blinding are, however, complex, and often difficult to discern from trial reports. Nonetheless, these insights have the potential to change trial design, conduct, and reporting and will inform guideline development.

BackgroundAcquired laryngotracheal stenosis (LTS) is a rare condition that causes breathlessness and dyspnoea. Patients have reconstructive airway surgery to improve their breathing difficulties, but both LTS and the surgery can cause voice difficulties. The existing evidence base for management of the voice difficulties for adults with LTS focuses on symptoms. There is limited information to provide clinical guidance for speech and language therapists (SLTs), and limited understanding of the impact of voice changes on adults with LTS. AimTo investigate the lived experience of adults with laryngotracheal stenosis (LTS), who have had reconstructive surgery; here focussing on voice concerns with the aim of guiding clinical care for SLTs.Methods & ProceduresA phenomenological, qualitative study design was used. Focus groups and semi-structured interviews were completed with adults living with LTS who had had reconstructive surgery. Audio-recordings were transcribed and inductive thematic analysis was used by the research team to identify themes and sub-themes. Outcomes & ResultsA total of 24 participants (5 focus groups and 2 interviews) took part in the study before thematic saturation was identified in analysis. Three main themes were identified specific to the experience of living with LTS: the Medical, Physical and Emotional journey. All participants referenced voice difficulties as they related to each of these overall themes. Sub-themes directly related to voice included: experience of surgery, information provision, staff expertise/complacency, symptoms, symptom management, identity, support networks, impact on life and living with a chronic condition. Conclusions & ImplicationsIn this qualitative study participants have described the integral part voice difficulties play in their lived experience of LTS and reconstructive surgery. This is considered in the context of their clinical care and the need for individualised management and information prov
Ding Z, Henson D, Sivapuratharasu B, et al., 2023, The effect of muscle atrophy in people with unilateral transtibial amputation for three activities: gait alone does not tell the whole story, Journal of Biomechanics, Vol: 149, Pages: 1-10, ISSN: 0021-9290
Amputation imposes significant challenges in locomotion to millions of people with limb loss worldwide. The decline in the use of the residual limb results in muscle atrophy that affects musculoskeletal dynamics in daily activities. The aim of this study was to quantify the lower limb muscle volume discrepancy based on magnetic resonance (MR) imaging and to combine this with motion analysis and musculoskeletal modelling to quantify the effects in the dynamics of key activities of daily living. Eight male participants with traumatic unilateral transtibial amputation were recruited who were at least six months after receiving their definitive prostheses. The muscle volume discrepancies were found to be largest at the knee extensors (35 %, p = 0.008), followed by the hip abductors (17 %, p = 0.008). Daily activities (level walking, standing up from a chair and ascending one step) were measured in a motion analysis laboratory and muscle and joint forces quantified using a detailed musculoskeletal model for people with unilateral transtibial amputation which was calibrated in terms of the muscle volume discrepancies post-amputation at a subject-specific level. Knee extensor muscle forces were lower at the residual limb than the intact limb for all activities (p ≤ 0.008); residual limb muscle forces of the hip abductors (p ≤ 0.031) and adductors (p ≤ 0.031) were lower for standing-up and ascending one step. While the reduced knee extensor force has been reported by other studies, our results suggest a new biomechanically-based mitigation strategy to improve functional mobility, which could be achieved through strengthening of the hip abd/adductor muscles.
Silverman AK, Hendershot BD, McGregor AH, 2023, Musculoskeletal Health After Blast Injury, Blast Injury Science and Engineering A Guide for Clinicians and Researchers: Second Edition, Pages: 489-497, ISBN: 9783031103544
Rehabilitation after blast injury is critical for regaining mobility and functional independence. In addition to immediate rehabilitation goals to facilitate activities of daily living, rehabilitation should address movement patterns and prosthetic interventions that mitigate long-term secondary (musculoskeletal) conditions. For example, after limb loss, which is a common result of blast trauma, people experience disproportionately high rates of osteoarthritis and low back pain relative to the general population. These conditions often develop and/or deteriorate over time and can have detrimental effects on mobility and quality of life. In this chapter, we describe and summarise existing knowledge of these musculoskeletal conditions secondary to blast injuries that include limb loss. Relationships between movement strategies and biomechanical outcomes are also discussed. While many musculoskeletal health conditions are multifactorial in onset and progression, these conditions are strongly related to movement biomechanics, and thus can be mitigated through rehabilitation approaches. Specifically, rehabilitation strategies that balance immediate goals of clinical outcomes and community engagement with long-term goals of healthy joint mechanics are critical for this population. In addition, rehabilitation and prosthetic interventions should be continually monitored and delivered so that they appropriately account for movement adaptations and changing mobility needs of the individual.
Hopkins M, McMenemy L, Turner S, et al., 2023, Sockets and Residuum Health, Blast Injury Science and Engineering A Guide for Clinicians and Researchers: Second Edition, Pages: 447-478, ISBN: 9783031103544
Major limb amputation affects millions of people worldwide and became a common procedure in the latter years of the conflicts in Afghanistan and Iraq. Prosthetic devices are commonly introduced to lower-limb amputees to assist with mobility and functionality. Despite vast leaps in the technology of lower-limb prostheses, acceptance of a prosthesis is limited by the quality of interfacing between the residuum and the device. No single design fits all, and production of a socket is a complex task, requiring significant skill and expertise from the prosthetist. The fit and pressure distribution of the socket can significantly impact the health of the soft tissue, leading to conditions such as pressure sores if not properly managed. The residuum-socket interface is further complicated by natural volume fluctuations of the limb, issues with thermoregulation, infections and musculoskeletal pathologies. Researchers, clinicians and industry have attempted to better understand and inform optimal socket fit through computational and hardware methods, and surgical techniques such as direct skeletal fixation have been proposed to bypass the socket altogether. This chapter explores the nature of the prosthetic socket, common issues users present and methods to improve the interface between the residual limb and the prosthesis.

Continued advances are required to address mobility limitations caused by lower extremity blast injury. Individuals who experience persistent deficits following trauma may benefit from external support and/or offloading provided by ankle foot orthoses (AFOs). Currently available AFOs vary widely in their design and potential benefit. Carbon fibre custom dynamic ankle foot orthoses (CDOs) have been increasingly used to improve mobility after traumatic injury. CDOs are made predominantly from carbon fibre and are intended to restore function across a range of daily and high-energy activities. Patient-reported outcomes, physical performance measures, and biomechanics data from studies focusing on CDO use have demonstrated positive outcomes. CDOs consist of a proximal cuff, posterior carbon fibre strut, and footplate, which can be tuned to meet the needs of the patient. Available literature provides guidance related to key design considerations during the fitting process. Further, intensive training when combined with the CDO has been found to enhance clinical outcomes and facilitate successful return to high-energy activity. A majority of available data related to CDO use following limb trauma is focused on a subset of military personnel, and available civilian data is limited.
Kaufmann JJ, McMenemy L, Phillips ATM, et al., 2023, Bone Health in Lower-Limb Amputees, Blast Injury Science and Engineering A Guide for Clinicians and Researchers: Second Edition, Pages: 479-488, ISBN: 9783031103544
Bone mineral density (BMD) loss in lower-limb amputees has in the past been referred to as either osteopenia or osteoporosis. However, evidence and hypotheses in emerging literature are beginning to challenge this, suggesting that the use of these terms could be inappropriate due to key differences in the aetiology and mechanisms underpinning the bone loss in the younger amputee population. Computational and clinical analysis carried out within the Centre for Blast Injury Studies at Imperial College London and the ADVANCE Study has provided strong evidence to support this stance. Investigating BMD discordance in the spine and femur of 153 lower-limb amputees and a frequency-matched control population has shown that bone loss in amputees is localised to the amputated limb rather than systemic (as it manifests in age-related osteoporosis). Combined musculoskeletal and finite element modelling goes some way to explaining the cause of this. Weight bearing through a prosthetic socket offloads the distal femur, and consequently large areas of the femoral shaft and neck experience significantly reduced levels of stimulation when compared to weight bearing on a healthy limb. The long-term result of this is a phenomenon that we refer to as unloading osteopenia.
Panhelleux B, Shalhoub J, Silverman A, et al., 2022, A review of through-knee amputation, Vascular, Vol: 30, Pages: 1149-1159, ISSN: 0967-2109
Objectives: Through knee amputation (TKA) is an umbrella term for several different surgical techniques, which may affect clinical and functional outcomes. This makes it hard to evaluate the benefits and need for a TKA approach. This paper seeks to: (1) Determine the number of TKAs performed compared with other major lower limb amputations (MLLA) in England over the past decade; (2) identify the theoretical concepts behind TKA surgical approaches and their potential effect on functional and clinical outcomes; and (3) provide a platform for discussion and research on TKA and surgical outcomes.Methods: National Health Service Hospital Episodes Statistics were used to obtain recent numbers of MLLAs in England. EMBASE and MEDLINE were searched using a systematic approach with predefined criteria for relevant literature on TKA surgery.Results: In the past decade, 4.6% of MLLA in England were TKAs. Twenty-six articles presenting TKA surgical techniques met our criteria. These articles detailed three TKA surgical techniques; the classical approach, which keeps the femur intact and retains the patella; the Mazet technique, which shaves the femoral condyles into a box shape; and the Gritti-Stokes technique, which divides the femur proximal to the level of the condyles and attaches the patella at the distal cut femur.Conclusions: TKA has persisted as a surgical approach over the past decade, with three core approaches identified. Studies reporting clinical, functional, and biomechanical outcomes of TKA frequently fail to distinguish between the 3 distinct and differing approaches, making direct comparisons difficult. Future studies that compare TKA approaches to one another and to other amputation levels are needed.

Rowland S, Fitzgerald EJ, Lungren M, et al., 2022, Digital health technology-specific risks for medical malpractice liability, npj Digital Medicine, Vol: 5, Pages: 1-6, ISSN: 2398-6352
The global digital health market is worth approximately 300 billion USD1 and is predicted to grow by up to 25% this year. Consequently, medical professionals are increasingly required to use digital technologies such as telehealth platforms, AI-driven clinical decision-making tools, digitally enabled surgical tools, mHealth technologies, or electronic health care records (EHR), as part of care delivery. These technologies hold clear benefits for enabling more efficient, modern care delivery however there are significant challenges to implementation, including when and how to use them, how to enable an accurate medical diagnosis in a virtual environment, interpretation and relevance of novel data points from digital devices, the potential for automation bias, appropriate utilisation of and engagement with digital disease management platforms and continuity of care in a digital world. Several of these issues have become apparent through the pandemic due to the hasty deployment of novel technologies as ‘bolt-on’ solutions to address standalone challenges in healthcare delivery, without consideration of the broader healthcare architecture. The majority of practicing clinicians are not sufficiently trained in how to safely integrate digital health technologies into the clinical workflow before encountering such technologies in practice. The introduction of digital health technologies may therefore represent a risk for medical error and subsequent malpractice liability. Medical malpractice is frequently defined as a physician’s failure to comply with customary medical practice,2 however the application of this standard in the context of digital health is challenging.

Clunie G, Anderson C, Hughes C, et al., 2022, “A major quality of life issue”: A survey-based analysis of the experiences of adults with laryngotracheal stenosis with mucus and cough, Annals of Otology, Rhinology and Laryngology, Vol: 131, Pages: 962-970, ISSN: 0003-4894
Objectives:To investigate how the symptoms of mucus and cough impact adults living with laryngotracheal stenosis, and to use this information to guide future research and treatment plans.Methods:A survey was developed with the support of patient advisors and distributed to people suffering with laryngotracheal stenosis. The survey comprised 15 closed and open questions relating to mucus and cough and included the Leicester Cough Questionnaire (LCQ). Descriptive statistics, X2 and thematic analyses were completed.Results:In total, 641 participants completed the survey, with 83.62% (n = 536) reporting problems with mucus; 79% having daily issues of varying severity that led to difficulties with cough (46.18%) and breathing (20.90%). Mucus affected voice and swallowing to a lesser degree. Respondents described a range of triggers; they identified smoky air as the worst environmental trigger. Strategies to manage mucus varied widely with drinking water (72.26%), increasing liquid intake in general (49.35%) and avoiding or reducing dairy (45.32%) the most common approaches to control symptoms. The LCQ showed a median total score of 14 (interquartile range 11-17) indicative of cough negatively affecting quality of life. Thematic analysis of free text responses identified 4 key themes—the Mucus Cycle, Social impact, Psychological impact, and Physical impact.Conclusion:This study shows the relevance of research focusing on mucus and cough and its negative impact on quality of life, among adults with laryngotracheal stenosis. It demonstrates the inconsistent advice and management strategies provided by clinicians for this issue. Further research is required to identify clearer treatment options and pathways.

Objective: Obtaining patient geometry is crucial in scoliosis brace design for patients with adolescent idiopathic scoliosis. Advances in 3D scanning technologies provide the opportunity to obtain patient geometries quickly with fewer resources during the design process compared with the plaster-cast method. This study assesses the accuracy and repeatability of such technologies for this application.Methods: The accuracy and repeatability of three different handheld scanners and phone-photogrammetry was assessed using different mesh generation software. Twenty-four scans of a single subject's torso were analyzed for accuracy and repeatability based on anatomical landmark distances and surface deviation maps.Results: Mark II and Structure ST01 scanners showed maximum mean surface deviations of 1.74 ± 3.63 mm and 1.64 ± 3.06 mm, respectively. Deviations were lower for the Peel 1 scanner (maximum of −0.35 ± 2.8 mm) but higher with the use of phone-photogrammetry (maximum of −5.1 ± 4.8 mm). The mean absolute errors of anatomical landmark distance measurements from torso meshes obtained with the Peel 1, Mark II, and ST01 scanners were all within 9.3 mm (3.6%), whereas phone-photogrammetry errors were as high as 18 mm (7%).Conclusions: Low-cost Mark II and ST01 scanners are recommended for obtaining torso geometries because of their accuracy and repeatability. Subject’s breathing/movement affects the resultant geometry around the abdominal and anterolateral regions.

Background: There is increasing recognition that prehabilitation is important as a means of preparing patients physically and psychologically for cancer treatment. However, little is understood about the role and optimal nature of prehabilitation for gynaecological cancer patients, who usually face extensive and life-changing surgery in addition to other treatments that impact significantly on physiological and psychosexual wellbeing. Review question: This scoping review was conducted to collate the research evidence on multimodal prehabilitation in gynaecological cancers and the related barriers and facilitators to engagement and delivery that should be considered when designing a prehabilitation intervention for this group of women. Methods: Seven medical databases and four grey literature repositories were searched from database inception to September 2021. All articles, reporting on multimodal prehabilitation in gynaecological cancers were included in the final review, whether qualitative, quantitative or mixed-methods. Qualitative on unimodal interventions were also included, as these were thought to be more likely to include information about barriers and facilitators which could also be relevant to multimodal interventions. A realist framework of context, mechanism and outcome was used to assist interpretation of findings. Results: In total, 24 studies were included in the final review. The studies included the following tumour groups: ovarian only (n=12), endometrial only (n=1), mixed ovarian, endometrial, vulvar (n=5) and non-specific gynaecological tumours (n=6). There was considerable variation across studies in terms of screening for prehabilitation, delivery of prehabilitation and outcome measures. Key mechanisms and contexts influencing engagement with prehabilitation can be summarised as: 1) The role of healthcare professionals and organisations 2) Patients’ perceptions of acceptability 3) Factors influencing patient motivation 4) Prehabilita

Blinding is challenging in randomised controlled trials (RCTs) of physical, psychological, and self-management therapies (PPS) for pain, mainly due to their complex and participatory nature. To develop standards for the design, implementation, and reporting of control interventions in efficacy and mechanistic trials, a systematic overview of currently employed sham interventions and other blinding methods was required.Twelve databases were searched for placebo or sham controlled RCTs of PPS treatments in a clinical pain population. Screening and data extraction were performed in duplicate, and trial features, description of control methods and their similarity to the active intervention under investigation were extracted (protocol registration ID: CRD42020206590).The review included 198 unique control interventions, published between 2008 and December 2021. Most trials studied people with chronic pain, and more than half were manual therapy trials. The described control interventions ranged from clearly modelled based on the active treatment, to largely dissimilar control interventions. Similarity between control and active interventions was more frequent for certain aspects (e.g., duration and frequency of treatments) than others (e.g., physical treatment procedures and patient sensory experiences). We also provide an overview of additional, potentially useful methods to enhance blinding, as well as the reporting of processes involved in developing control interventions.A comprehensive picture of prevalent blinding methods is provided, including a detailed assessment of the resemblance between active and control interventions. These findings can inform future developments of control interventions in efficacy and mechanistic trials and best-practice recommendations.
Allott N, McGregor A, Banger M, 2022, Evaluating the diagnostic pathway for acute ACL injuries in trauma centres: A systematic review, BMC Musculoskeletal Disorders, Vol: 23, ISSN: 1471-2474
Objective: This review sought to evaluate the literature on the initial assessment and diagnostic pathway for patients with a suspected Anterior Cruciate Ligament (ACL) tear.Methods: MEDLINE, EMBASE, and CINAHL were systematically searched for eligible studies, PRISMA guidelines were followed. Studies were included if they used at least one assessment method to assess for ACL injury and participants were assessed at an acute trauma centre within 6-weeks of injury. Article quality was evaluated using the QUADAS-2 checklist. Results: A total of 353 studies were assessed for eligibility, 347 were excluded for the following reasons: injuries were not assessed in an acute trauma setting, injuries were not acute, participants had previous ACL injuries or chronic joint deformities affecting the knee, participants were under 18, or participants included animals or cadavers. A total of six studies were included in the review. Common assessment methods included: laxity tests, joint effusion, inability to continue activity, and a history of a ‘pop’ and ‘giving way’ at the time of injury. Diagnostic accuracy varied greatly between the assessment method and the assessing clinician. Gold standard diagnostics were MRI and arthroscopy. A weighted meta-mean calculated the time to reach diagnosis to be 68.60 days [CI 23.94, 113.24]. The mean number of appointments to reach diagnosis varied from 2-5. Delay to surgery or surgical consultation ranged from 61 to 328 days. Conclusion: Clinicians in the Emergency Department are not proficient in performing the assessment methods that are used for diagnosis in acute ACL injury. Reliance on specialist assessments or radiological methods inevitably increases the time to reach a diagnosis, which has repercussions on management options. There is an ever-growing demand to improve diagnostic accuracy and efficiency; further exploration into , quantitative measures of instability would aid the assessment of peripheral joi
Hopkins M, Turner S, McGregor A, 2022, Mapping lower-limb prosthesis load distributions using a low-cost pressure measurement system, Frontiers in Medical Technology, Vol: 4, Pages: 1-9, ISSN: 2673-3129
Background: In the UK 55,000 people live with a major limb amputation. The prosthetic socket is problematic for users in relation to comfort and acceptance of the prosthesis; and is associated with the development of cysts and sores.Objectives: We have developed a prototype low-cost system combining low-profile pressure sensitive sensors with an inertial measurement unit to assess loading distribution within prosthetic sockets. The objective of this study was to determine the ability of this prototype to assess in-socket loading profiles of a person with an amputation during walking, with a view to understanding socket design and fit.Methods: The device was evaluated on four transtibial participants of various age and activity levels. The pressure sensors were embedded in the subject's sockets and an inertial measurement unit was attached to the posterior side of the socket. Measurements were taken during level walking in a gait lab.Results: The sensors were able to dynamically collect data, informing loading profiles within the socket which were in line with expected distributions for patellar-tendon-bearing and total-surface-bearing sockets. The patellar tendon bearing subject displayed loading predominately at the patellar tendon, tibial and lateral gastrocnemius regions. The total-surface bearing subjects indicated even load distribution throughout the socket except in one participant who presented with a large socket-foot misalignment.Conclusions: The sensors provided objective data showing the pressure distributions inside the prosthetic socket. The sensors were able to measure the pressure in the socket with sufficient accuracy to distinguish pressure regions that matched expected loading patterns. The information may be useful to aid fitting of complex residual limbs and for those with reduced sensation in their residual limb, alongside the subjective feedback from prosthesis users.
Greenwood J, Hurley M, McGregor A, et al., 2022, A qualitative evaluation of participants experiences of living with back pain, lumbar fusion surgery, and post-operative rehabilitation, Pilot and Feasibility Studies, Vol: 8, ISSN: 2055-5784
BackgroundThe use of lumbar fusion surgery is increasing in developed economies. High levels of patient dissatisfaction are reported post-operatively. To address this need, we developed a theoretically informed rehabilitation programme for use following lumbar fusion surgery (the REFS programme). We conducted a mixed methods randomised controlled feasibility study (REFS v ‘usual care’). The numerical and feasibility outcomes are reported separately. The current qualitative study was ‘nested’ within the main feasibility study to explore participants’ experiences before and after lumbar fusion surgery including the impact of rehabilitation content. This facilitated a deeper understanding of potential mechanisms of action, for theoretical and programme refinement.MethodsA purposive sample (n = 10 ‘usual care’, n = 10 REFS) was identified from the main feasibility study cohort. Individual semi-structured interviews were conducted post-operatively (median 8 months, range 5–11). Interview data were transcribed verbatim, coded, and analysed thematically.ResultsThree themes were constructed: the breadth and severity of impact associated with a chronic lumbar disorder was summarised in theme 1, ‘Ever-decreasing circles; living with a chronic lumbar disorder’. Theme 2, ‘What have I done? Reflections on recovery from lumbar fusion surgery’, illustrated participants post-operative helplessness, which was associated with worsening mental health, problematic use of opioids, fear related to the instillation of metalware, and the important mitigating effect of informal social support. Theme 3 ‘Rehabilitation experiences’ identified critical rehabilitation programme content including exercise, a shared rehabilitation experience, the opportunity for vicarious learning, and professional expertise.ConclusionsTo enhance patient benefit future REFS programme iterations s
