Sperry MM, Phillips ATM, McGregor AH, 2019, Lower back pain and healthy subjects exhibit distinct lower limb perturbation response strategies: A preliminary study., J Back Musculoskelet Rehabil, Vol: 32, Pages: 27-35
BACKGROUND: It is hypothesized that inherent differences in movement strategies exist between control subjects and those with a history of lower back pain (LBP). Previous motion analysis studies focus primarily on tracking spinal movements, neglecting the connection between the lower limbs and spinal function. Lack of knowledge surrounding the functional implications of LBP may explain the diversity in success from general treatments currently offered to LBP patients. OBJECTIVE: This pilot study evaluated the response of healthy controls and individuals with a history of LBP (hLBP) to a postural disturbance. METHODS: Volunteers (n= 26) were asked to maintain standing balance in response to repeated balance disturbances delivered via a perturbation platform while both kinematic and electromyographic data were recorded from the trunk, pelvis, and lower limb. RESULTS: The healthy cohort utilized an upper body-focused strategy for balance control, with substantial activation of the external oblique muscles. The hLBP cohort implemented a lower limb-focused strategy, relying on activation of the semitendinosus and soleus muscles. No significant differences in joint range of motion were identified. CONCLUSIONS: These findings suggest that particular reactive movement patterns may indicate muscular deficits in subjects with hLBP. Identification of these deficits may aid in developing specific rehabilitation programs to prevent future LBP recurrence.

Musculoskeletal models permit the determination of internal forces acting during dynamic movement, which is clinically useful, but traditional methods may suffer from slowness and a need for extensive input data. Recently, there has been interest in the use of supervised learning to build approximate models for computationally demanding processes, with benefits in speed and flexibility. Here, we use a deep neural network to learn the mapping from movement space to muscle space. Trained on a set of kinematic, kinetic and electromyographic measurements from 156 subjects during gait, the network's predictions of internal force magnitudes show good concordance with those derived by musculoskeletal modelling. In a separate set of experiments, training on data from the most widely known benchmarks of modelling performance, the international Grand Challenge competitions, generates predictions that better those of the winning submissions in four of the six competitions. Computational speedup facilitates incorporation into a lab-based system permitting real-time estimation of forces, and interrogation of the trained neural networks provides novel insights into population-level relationships between kinematic and kinetic factors.

Cowell I, O'Sullivan P, O'Sullivan K, et al., 2018, The perspectives of physiotherapists on managing nonspecific low back pain following a training programme in cognitive functional therapy: A qualitative study., Musculoskeletal Care
BACKGROUND: It has long been acknowledged that nonspecific chronic low back pain (NSCLBP) is associated with a complex combination of biopsychosocial (BPS) factors, and recent guidelines advocate that the management of back pain should reflect this multidimensional complexity. Cognitive functional therapy (CFT) is a behaviourally oriented intervention that targets patients' individual BPS profiles. Although the efficacy of CFT has been demonstrated in primary care, little evidence exists about the training requirements of this approach. METHODS: Qualitative semistructured interviews were conducted with 10 physiotherapists working in primary care, who had undergone a formal training programme in CFT. A purposive sampling method was employed to seek the broadest perspectives. Thematic analysis was used to analyse the interview transcripts and capture the emergent themes. RESULTS: Five main themes emerged: (i) the learning challenge; (ii) self-reported changes in confidence; (iii) self-reported changes in communication practice; (iv) self-reported changes in attitudes and understanding; (v) the physiotherapists felt that CFT was more effective than their usual approach for NSCLBP but identified barriers to successful implementation, which included a lack of time and difficulties in engaging patients with strong biomedical beliefs. CONCLUSIONS: The study suggested that training in CFT has the capacity to produce self-reported changes in physiotherapists' attitudes, confidence and practice. The provision of such training has implications in terms of time and costs; however, this this may be warranted, given the physiotherapists' strong allegiance to the approach compared with their usual practice.

Wong JKL, McGregor AH, 2018, Spatiotemporal gait changes in healthy pregnant women and women with pelvic girdle pain: A systematic review., Journal of Back and Musculoskeletal Rehabilitation, ISSN: 1053-8127
INTRODUCTION: Gait is affected in women with pelvic girdle pain (PGP), a musculoskeletal condition affecting 20% of pregnant women. Whilst there is evidence of spatiotemporal changes in gait during healthy pregnancy, less is known in relation to women with PGP. Appreciating gait characteristics during healthy pregnancy could inform our understanding of the role of gait in PGP. PURPOSE: The purpose of this review was to systematically analyse differences in the spatiotemporal parameters of gait in healthy pregnant women and those with PGP, and to make recommendations to improve research methods in investigating gait in PGP women. METHODS: The review was undertaken following the PRISMA guidelines. Three databases and pre-existing literature were electronically and manually searched. Study selection and data extraction were conducted by two reviewers. Quality assessment was performed using the NHLBI tool for Observational Cohort and Cross-sectional Studies. RESULTS: The search returned 2925 results. Fourteen studies were selected for data extraction. Twelve studies investigated gait in healthy pregnant women and two in PGP women. Studies employed either a cohort or cross-sectional design and used various methods to assess gait. Three, nine and two studies were high, medium and low in quality, respectively. Direct comparisons between studies were impeded due to incomparable gestational time-points investigated, in addition to variations in gait parameters and definitions used. CONCLUSION: Evidence from studies on healthy pregnant women could inform future research on PGP women, for which current evidence is scarce. We recommend the standardisation of critical factors to allow inter-study comparisons for a meta-analysis.

Background: This study aimed to characterise knee adduction angles (KAA) and knee adduction moments (KAM) and compare this with foot centre of pressure (COP) in volunteers with and without knee osteoarthritis (OA). Methods: A total of 108 participants were recruited; 84 had no known pathology, 18 had medial knee OA, and six had lateral knee OA. Linear regression was used to determine correlations between the normalised COP, KAM, and KAA during each phase of gait for all participants. Results: The first phase of gait demonstrated significant differences between groups for all measures: KAA in all phases, COP in phases one and two, and KAM in phase one only. Conclusion: The largest mechanical changes are seen in the first phase of gait in osteoarthritic patients. Although COP is an easy to measure tool, it is not as sensitive as KAA and did not demonstrate a significant difference between healthy and medial OA patients.
