ItemDetermining Expected Research Skills of Medical Students on Graduation: a Systematic Review(Springer, 2020-12)BACKGROUND: Global interest in research skills in undergraduate medical education is growing. There is no consensus regarding expected research skills of medical students on graduation. We conducted a systematic review to determine the aims and intended learning outcomes (ILOs) of mandatory research components of undergraduate medical curricula incorporating the teaching, assessment, and evaluation methods of these programs. METHODS: Using the PRISMA protocol, MEDLINE and ERIC databases were searched with keywords related to "medical student research programs" for relevant articles published up until February 2020. Thematic analysis was conducted according to student experience/reactions, mentoring/career development, and knowledge/skill development. RESULTS: Of 4880 citations, 41 studies from 30 institutions met the inclusion criteria. Programs were project-based in 24 (80%) and coursework only-based in 6 (20%). Program aims/ILOs were stated in 24 programs (80%). Twenty-seven different aims/ILOs were identified: 19 focused on knowledge/skill development, 4 on experience/reactions, and 4 on mentoring/career development. Project-based programs aimed to provide an in-depth research experience, foster/increase research skills, and critically appraise scientific literature. Coursework-based programs aimed to foster/apply analytical skills for decision-making in healthcare and critically appraise scientific literature. Reporting of interventions was often incomplete, short term, and single institution. There was poor alignment between aims, teaching, assessment, and evaluation methods in most. CONCLUSIONS: The diversity of teaching programs highlights challenges in defining core competencies in research skills for medical graduates. Incomplete reporting limits the evidence for effective research skills education; we recommend those designing and reporting educational interventions adopt recognized educational reporting criteria when describing their findings. Whether students learn by "doing", "proposing to do", or "critiquing", good curriculum design requires constructive alignment between teaching, assessment, and evaluation methods, aims, and outcomes. Peer-reviewed publications and presentations only evaluate one aspect of the student research experience.

ItemAndrogens In Men Study (AIMS): protocol for meta-analyses of individual participant data investigating associations of androgens with health outcomes in men(BMJ PUBLISHING GROUP, 2020-05)INTRODUCTION: This study aims to clarify the role(s) of endogenous sex hormones to influence health outcomes in men, specifically to define the associations of plasma testosterone with incidence of cardiovascular events, cancer, dementia and mortality risk, and to identify factors predicting testosterone concentrations. Data will be accrued from at least three Australian, two European and four North American population-based cohorts involving approximately 20 000 men. METHODS AND ANALYSIS: Eligible studies include prospective cohort studies with baseline testosterone concentrations measured using mass spectrometry and 5 years of follow-up data on incident cardiovascular events, mortality, cancer diagnoses or deaths, new-onset dementia or decline in cognitive function recorded. Data for men, who were not taking androgens or drugs suppressing testosterone production, metabolism or action; and had no prior orchidectomy, are eligible. Systematic literature searches were conducted from 14 June 2019 to 31 December 2019, with no date range set for searches. Aggregate level data will be sought where individual participant data (IPD) are not available. One-stage IPD random-effects meta-analyses will be performed, using linear mixed models, generalised linear mixed models and either stratified or frailty-augmented Cox regression models. Heterogeneity in estimates from different studies will be quantified and bias investigated using funnel plots. Effect size estimates will be presented in forest plots and non-negligible heterogeneity and bias investigated using subgroup or meta-regression analyses. ETHICS AND DISSEMINATION: Ethics approvals obtained for each of the participating cohorts state that participants have consented to have their data collected and used for research purposes. The Androgens In Men Study has been assessed as exempt from ethics review by the Human Ethics office at the University of Western Australia (file reference number RA/4/20/5014). Each of the component studies had obtained ethics approvals; please refer to respective component studies for details. Research findings will be disseminated to the scientific and broader community via the publication of four research articles, with each involving a separate set of IPD meta-analyses (articles will investigate different, distinct outcomes), at scientific conferences and meetings of relevant professional societies. Collaborating cohort studies will disseminate findings to study participants and local communities. PROSPERO REGISTRATION NUMBER: CRD42019139668.

ItemInterdisciplinary management for chronic pain in central neurological disorders: a retrospective study(Mark Allen Healthcare, 2020-01-02)Background/aims: Chronic pain in central neurological disorders is common and the current management of chronic pain is through an interdisciplinary approach. The aim of this study was to compare outpatient interdisciplinary-based treatment for chronic pain in patients with central neurological disorders to those without central neurological disorders. Methods: This was a retrospective study and pain-related outcome measures were collected from a clinical outcomes registry (electronic Persistent Pain Outcomes Collaboration). This registry contained data on people who attended a pain management service who, for the purpose of this study, were categorised into those with a central neurological disorder and those without a central neurological disorder. The two sample t-test was used to determine the significance of the difference between the groups and statistical significance was defined as P<0.05. Outcome measures compared included the Brief Pain Inventory, Depression, Anxiety and Stress Scale 21, Patient Self-efficacy Questionnaire and Patient Catastrophisation Scale. Results: There was a total of 1924 participants with a central neurological disorder. The electronic Persistent Pain Outcomes Collaboration registry shows that after engagement with an interdisciplinary pain management service, there was a reduction in pain severity scores, interference, mean depression, anxiety and stress in both groups at end of an episode of care compared to referral. There was a significant difference in mean changes for pain catastrophising between those with a central neurological disorder (−10.3) and those without (−7.8). Conclusions: This study shows that people with central neurological disorders can also benefit from interdisciplinary management and have similar results to those without these conditions.

ItemHigh-Level Mobility Assessment Tool Normative Values for Children(OXFORD UNIV PRESS INC, 2020-02)BACKGROUND: Physical therapists need to be able to evaluate high-level gross motor skills of children to determine their capacity to engage in activities such as running, jumping, hopping, and stair climbing. The High-Level Mobility Assessment Tool (HiMAT) has excellent interrater and retest reliability and is less susceptible to a ceiling effect than existing mobility scales in children who are 6 to 17 years old and have traumatic brain injury. OBJECTIVE: The purposes of this study were to develop normative HiMAT score ranges for Australian children and to investigate the relationship between children's HiMAT scores and their age, height, weight, and body mass index (BMI). DESIGN: This study used a cross-sectional design. METHODS: Children included in this study were 5 to 12 years old, had no condition affecting their mobility, could follow 2-stage instructions, and had written informed consent from their parent or guardian. A total 1091 children were assessed at their local school, where their height, weight, and HiMAT score were recorded. The relationships between children's age, height, weight, and BMI were summarized using Spearman rank correlations. Truncated regression models were used to determine the most appropriate predictor variable for developing sex-specific normative ranges. RESULTS: There was a positive correlation between children's HiMAT scores and their age, height, weight, and BMI. Age explained the most variability in HiMAT scores for both boys and girls. LIMITATIONS: The reliability, validity, and responsiveness of the HiMAT have not been tested across a broad range of children with mobility limitations. Normative data reported in this study are for Australian children only. CONCLUSIONS: HiMAT scores for children in this study increased with age, height, weight, and BMI. Age was the most appropriate variable for developing a normative dataset of HiMAT scores for children of primary school age.

ItemDisaster Rehabilitation Response Plan Now or Never(LIPPINCOTT WILLIAMS & WILKINS, 2020-02)There is a strong consensus among humanitarian response authorities for a need for global action by professional organizations to work toward developing a structured approach to provide a coordinated international response during sudden-onset disasters. The aim of this report was to develop a Disaster Rehabilitation Response Plan to enable International Society of Physical and Rehabilitation Medicine to provide leadership and governance role in liaison/coordination with the WHO emergency medical team initiative and other relevant stakeholders to provide rehabilitation input during sudden-onset disasters. The proposed plan uses a "three-tier approach": tier 1, immediate disaster response at a national/international level; tier 2, organization and deployment of rehabilitation personnel; and tier 3, rehabilitation management of disaster survivors and community reintegration. The International Society of Physical and Rehabilitation Medicine (and its subcommittee, the Disaster Rehabilitation Committee), categorized in the tier 2, could provide central leadership role working for the rehabilitation subcluster within the WHO emergency medical team initiative (tier 1) and support in coordination, preparation, and management of rehabilitation teams and/or members for deployment to sudden-onset disasters. The Disaster Rehabilitation Committee could also contribute to advocacy, training, and accreditation processes for rehabilitation professionals. The challenge ahead is commitment of countries worldwide to develop comprehensive rehabilitation-inclusive approach to ensure effective delivery of services to communities at risk.

ItemGait compensatory mechanisms in unilateral transfemoral amputees(Elsevier, 2020-03)Individuals with unilateral transfemoral amputation depend on compensatory muscle and joint function to generate motion of the lower limbs, which can produce gait asymmetry; however, the functional role of the intact and residual limb muscles of transfemoral amputees in generating progression, support, and mediolateral balance of the body during walking is not well understood. The aim of this study was to quantify the contributions of the intact and the residual limb's contralateral muscles to body center of mass (COM) acceleration during walking in transfemoral amputees. Three-dimensional subject-specific musculoskeletal models of 6 transfemoral amputees fitted with a socket-type prosthesis were developed and used to quantify muscle forces and muscle contributions to the fore-aft, vertical, and mediolateral body COM acceleration using a pseudo-inverse ground reaction force decomposition method during over-ground walking. Anterior pelvic tilt and hip range of motion in the sagittal and frontal planes of the intact limb was significantly larger than those in the residual limb (p<0.05). The mean contributions of the intact limb hip muscles to body COM support, forward propulsion and mediolateral balance were significantly greater than those in the residual limb (p<0.05). Gluteus maximus contributed more to propulsion and support, while gluteus medius contributed more to balance than other muscles in the intact limb than the residual limb. The findings demonstrate the role of the intact limb hip musculature in compensating for reduced or absent muscles and joint function in the residual limb of transfemoral amputees during walking. The results may be useful in developing rehabilitation programs and design of prostheses to improve gait symmetry and mitigate post-operative musculoskeletal pathology.

ItemReanimating hand function after spinal cord injury using nerve transfer surgery(Whitehouse Publishing, 2020-03)Loss of arm and hand function is a devastating consequence of cervical spinal cord injury. Tendon transfer surgery has traditionally been used to restore key functions including elbow extension, wrist extension and grasp and pinch. The more recent development of nerve transfer surgery enables direct restoration of voluntary control of these functions. While both types of surgery are safe and effective, nerve transfer surgery results in a more open, flexible and natural hand, with more subtle control for a range of activities of daily living.

ItemMultidisciplinary Rehabilitation in Persons with Multliple Trauma: A Systematic Review(Medical Journals Sweden, 2020-10-01)Objective: To determine the effectiveness of multidisciplinary rehabilitation in improving functional and psychological outcomes in person with multiple trauma. Date sources: A comprehensive literature review was conducted using medical and health science electronic databases up to February 2019. Data extraction: Two independent reviewers selected studies, extracted data and assessed study quality using the Critical Appraisal Skills Programme (CASP) checklists and Grading of Recommendations, Assessment, Development and Evaluations (GRADE). Data synthesis: One randomized controlled trial, 1 clinical controlled trial and 4 observational studies (1 with 2 reports) were included. Qualitative analysis was used to synthesize the evidence due to the heterogeneity of included trials. The quality of the studies varied (CASP approach); the majority were of “low quality”. The findings suggest “very low to moderate” evidence (GRADE) for the effectiveness of multidisciplinary rehabilitation in improving functional ability and participation. The majority of studies (n = 6) reported functional improvements after multidisciplinary rehabilitation in the short-term. Conclusion: The lack of “high-quality” evidence for multidisciplinary rehabilitation in improving outcomes following trauma highlights gaps in the available evidence, signifying the need for more robust studies.

ItemThe Effect of Transcranial Direct Current Stimulation on Chronic Neuropathic Pain in Patients with Multiple Sclerosis: Randomized Controlled Trial(OXFORD UNIV PRESS, 2020-12)OBJECTIVE: Chronic neuropathic pain is a common symptom in multiple sclerosis (MS). This randomized controlled single-blinded study investigated whether a new protocol involving five days of transcranial direct current stimulation (tDCS) with an interval period would be effective to reduce pain using the visual analog scale (VAS). Other secondary outcomes included the Neuropathic Pain Scale (NPS), Depression Anxiety Stress Score (DASS), Short Form McGill Pain Questionnaire (SFMPQ), and Multiple Sclerosis Quality of Life 54 (MSQOL54). DESIGN: A total of 30 participants were recruited for the study, with 15 participants randomized to a sham group or and 15 randomized to an active group. After a five-day course of a-tDCS, VAS and NPS scores were measured daily and then weekly after treatment up to four weeks after treatment. Secondary outcomes were measured pretreatment and then weekly up to four weeks. RESULTS: After a five-day course of a-tDCS, VAS scores were significantly reduced compared with sham tDCS and remained significantly low up to week 2 post-treatment. There were no statistically significant mean changes in MSQOL54, SFMPQ, NPS, or DASS for the sham or treatment group before treatment or at four-week follow-up. CONCLUSIONS: This study shows that repeated stimulation with a-tDCS for five days can reduce pain intensity for a prolonged period in patients with MS who have chronic neuropathic pain.

ItemIndividual muscle contributions to hip joint-contact forces during walking in unilateral transfemoral amputees with osseointegrated prostheses(Taylor & Francis, 2020-07-21)Direct skeletal attachment of prostheses in transfemoral amputees circumvents skin-interface complications associated with conventional sockets; however, joint pain and musculoskeletal disease is known to occur postoperatively. This study quantified hip contact forces and the roles of individual muscles in producing hip contact forces during walking in transfemoral amputees with osseointegrated prostheses. Musculoskeletal models were developed for four transfemoral amputees. Gluteus maximus and gluteus medius were the major contributors to the hip contact forces, and the intact limb hip muscles demonstrated greater contributions to hip contact forces than those of the residual limb. The findings may be useful for mitigating walking asymmetry.
