Effect of running retraining on pain, function, and lower-extremity biomechanics in a female runner with iliotibial band syndrome.

CONTEXT: Iliotibial-band syndrome (ITBS) is a common overuse running injury. There is inconclusive evidence to support current management strategies, and few advances have been made in the past few years. New management approaches should thus be developed and evaluated. OBJECTIVE: To assess the effects of a real-time running-retraining program on lower-extremity biomechanics, pain while running, and function. DESIGN: Single-subject experimental study. SETTING: University motion-analysis laboratory. PARTICIPANT: Female recreational runner with ITBS. INTERVENTION: Nine real-time running-retraining sessions were implemented based on the biomechanical alterations of the participant's symptomatic lower limb, including pelvic and knee movement in the transverse plane, as well as foot movement in the frontal plane. Real-time visual feedback of the pelvic-rotation angle was provided during the running-retraining sessions. MAIN OUTCOME MEASUREMENTS: 3-dimensional lower-extremity running kinematics, pain on a verbal analog scale while running on a treadmill, and the Lower Extremity Functional Scale (LEFS). RESULTS: Pelvic external rotation decreased, although the aim was to increase pelvic external rotation and knee rotation. The foot-progression angle improved after the intervention and at 1-mo follow-up. There was a 12.5% improvement in running time, and the pain score while running improved by 50% postintervention; these improvements were maintained at 1-mo follow-up. The mean LEFS score, indicative of function, improved by 8.75% and by 10% at the end of the intervention and at 1-mo follow-up, respectively. CONCLUSION: The real-time running-retraining program improved pain while running, as well as function, and was effective in addressing the lower-limb biomechanical alterations of the knee and foot in a female runner with ITBS. The application, effectiveness, and feasibility of real-time training should be addressed in larger studies in the future.

The effect of physical exercise on anxiety in people with parkinson's disease: A systematic review of randomized control trials.

BACKGROUND: Anxiety is a prominent disabling non-motor neuropsychiatric complication of Parkinson's disease (PD). Pharmacological treatments for PD and anxiety have drug interactions and negative side effects. Therefore, non-pharmacological interventions such as exercise has been proposed to reduce anxiety in people with PD (PwP). OBJECTIVE: This systematic review aimed to explore the relationship between physical exercise and anxiety in PwP. METHOD: Four databases (PubMed, Embase, Scopus, Ebscohost) were searched without date restrictions. English randomized control trials (RCT) including adults with PD, exposed to physical exercise interventions with anxiety as an outcome variable, were included. Quality was assessed by means of an adapted 9-point PEDro scale. RESULTS: Five of the identified 5547 studies met the inclusion criteria. Sample size ranged between 11-152 participants, totaling 328 participants with majority being male. PD stage ranged from early to moderate, with disease duration ranged between 2.9 and 8.0 years. All studies measured anxiety at baseline and post-intervention. On average studies scored 7/9 (76%) on the PEDro scale. CONCLUSION: There is insufficient evidence to support or refute the effect of exercise on anxiety in PwP due to noted limitations of included studies. There is an urgent need for high-quality RCTs on physical exercise and anxiety in PwP.

The effectiveness of a chair intervention in the workplace to reduce musculoskeletal symptoms. A systematic review.

BACKGROUND: Prolonged sitting has been associated with musculoskeletal dysfunction. For desk workers, workstation modifications frequently address the work surface and chair. Chairs which can prevent abnormal strain of the neuromuscular system may aid in preventing musculo-skeletal pain and discomfort. Anecdotally, adjustability of the seat height and the seat pan depth to match the anthropometrics of the user is the most commonly recommended intervention. Within the constraints of the current economic climate, employers demand evidence for the benefits attributed to an investment in altering workstations, however this evidence-base is currently unclear both in terms of the strength of the evidence and the nature of the chair features. The purpose of this study was to evaluate the evidence for the effectiveness of chair interventions in reducing workplace musculoskeletal symptoms. METHODS: Pubmed, Cinahl, Pedro, ProQuest, SCOPUS and PhysioFocus were searched. 'Ergonomic intervention', 'chair', 'musculoskeletal symptoms', 'ergonomics', 'seated work' were used in all the databases. Articles were included if they investigated the influence of chair modifications as an intervention; participants were in predominantly seated occupations; employed a pre/post design (with or without control or randomising) and if the outcome measure included neuro-musculoskeletal comfort and/or postural alignment. The risk of bias was assessed using a tool based on The Cochrane Handbook. RESULTS: Five studies were included in the review. The number of participants varied from 4 to 293 participants. Three of the five studies were Randomised Controlled Trials, one pre and post-test study was conducted and one single case, multiple baselines (ABAB) study was done. Three studies were conducted in a garment factory, one in an office environment and one with university students. All five studies found a reduction in self-reported musculoskeletal pain immediately after the intervention. Bias was introduced due to poor randomization procedures and lack of concealed allocation. Meta-analysis was not possible due to the heterogeneity of the data (differing population, intervention and outcomes across studies). CONCLUSION: The findings of this review indicate a consistent trend that supports the role of a chair intervention to reduce musculoskeletal symptoms among workers who are required to sit for prolonged periods. However the amount, level and quality of the evidence are only moderate therefore we cannot make strong recommendations until further trials are conducted. The review also highlights gaps: for example in showing whether the effectiveness of a chair intervention has long-term impact, particularly with respect to musculoskeletal symptoms, as well as the recurrence of symptoms and the consequent cost of care.

Perspectives of spinal health within the school setting in a South African rural region: A qualitative study.

BACKGROUND: Spinal pain is one of the leading causes of morbidity globally. There is an increase in the number of children and adolescents who experience spinal pain and the lifetime prevalence of adolescent spinal pain varies between countries. In Africa, one in two adolescents experiences spinal pain and the prevalence is increasing. OBJECTIVE: This study reports on the knowledge and perspectives of school-attending children, adolescents, teachers, and parents/guardians regarding spinal health. METHODS: We conducted a descriptive qualitative case study with an interpretative and phenomenological approach. Data coding, management and analysis was done using ATLAS.ti computer software. RESULTS: Ninety-three participants (66 women and 27 men) were enrolled in the study. The barriers associated with students' spinal health were multifactorial, including low levels of physical activity, dangerous gameplay, sports risks, poor ergonomics, school bags, insufficient knowledge, and pregnancy risks. Participants proposed strategies to improve spinal health including the provision of students' lockers, advice on appropriate school bag types, embedding spinal education in the curriculum, general advocacy for spinal health, and integration of technology in teaching and learning. CONCLUSION: There is a need for further engagement on school-based spinal health promotion programs that consider local socio-economic, educational, and cultural factors.

Towards universal health coverage for people with stroke in South Africa: a scoping review.

OBJECTIVES: To explore the opportunities and challenges within the health system to facilitate the achievement of universal health coverage (UHC) for people with stroke (PWS) in South Africa (SA). SETTING: SA. DESIGN: Scoping review. SEARCH METHODS: We conducted a scoping review of opportunities and challenges to achieve UHC for PWS in SA. Global and Africa-specific databases and grey literature were searched in July 2020. We included studies of all designs that described the healthcare system for PWS. Two frameworks, the Health Systems Dynamics Framework and WHO Framework, were used to map data on governance and regulation, resources, service delivery, context, reorientation of care and community engagement. A narrative approach was used to synthesise results. RESULTS: Fifty-nine articles were included in the review. Over half (n=31, 52.5%) were conducted in Western Cape province and most (n=41, 69.4%) were conducted in urban areas. Studies evaluated a diverse range of health system categories and various outcomes. The most common reported component was service delivery (n=46, 77.9%), and only four studies (6.7%) evaluated governance and regulation. Service delivery factors for stroke care were frequently reported as poor and compounded by context-related limiting factors. Governance and regulations for stroke care in terms of government support, investment in policy, treatment guidelines, resource distribution and commitment to evidence-based solutions were limited. Promising supporting factors included adequately equipped and staffed urban tertiary facilities, the emergence of Stroke units, prompt assessment by health professionals, positive staff attitudes and care, two clinical care guidelines and educational and information resources being available. CONCLUSION: This review fills a gap in the literature by providing the range of opportunities and challenges to achieve health for all PWS in SA. It highlights some health system areas that show encouraging trends to improve service delivery including comprehensiveness, quality and perceptions of care.

Spinal tuberculosis: A systematic review of case studies and development of an evidence-based clinical guidance tool for early detection.

RATIONALE, AIMS, AND OBJECTIVES: Despite research being done on spinal tuberculosis, diagnosing this condition at an early stage remains problematic due to its insidious onset and the varying symptoms being associated. Most individuals present to the health care facility with either simple back pain at an early stage or neurological complications at a later stage, when spinal compression and vertebral collapse have occurred as a result of delayed diagnosis. The prevention of secondary complications is therefore dependent on early recognition and diagnosis. The objective of this review was to identify common clinical patterns in case presentations and develop an evidence-based clinical guidance tool to assist clinicians in the early identification of spinal tuberculosis. METHOD: A comprehensive literature search was conducted for published spinal tuberculosis case studies, which yielded 28 cases after critical appraisal. Data from the studies were categorized in order to assist with a factor analysis and the development of an evidence framework for screening and diagnosing spinal tuberculosis. An evidence-based clinical guidance tool was then designed from the data obtained. RESULTS: Factors associated with spinal tuberculosis and frequently reported symptoms and physical signs with which the patient could present upon assessment were identified. Options for investigations at primary, secondary, and tertiary levels were also identified. CONCLUSION: Through the use of an evidence-based clinical guidance tool, the clinician could be guided in the early suspicion and management of individuals with spinal tuberculosis and prevention of secondary complications.

Achieving universal health coverage for people with stroke in South Africa: protocol for a scoping review.

INTRODUCTION: Stroke is the second most common cause of death after HIV/AIDS and a significant health burden in South Africa. The extent to which universal health coverage (UHC) is achieved for people with stroke in South Africa is unknown. Therefore, a scoping review to explore the opportunities and challenges within the South African health system to facilitate the achievement of UHC for people with stroke is warranted. METHODS AND ANALYSIS: The scoping review will follow the approach recommended by Levac, Colquhoun and O'Brien, which includes five steps: (1) identifying the research question, (2) identifying relevant studies, (3) selecting the studies, (4) charting the data, and (5) collating, summarising and reporting the results. Health Systems Dynamics Framework and WHO Framework on integrated people-centred health services will be used to map, synthesise and analyse data thematically. ETHICS AND DISSEMINATION: Ethical approval is not required for this scoping review, as it will only include published and publicly available data. The findings of this review will be published in an open-access, peer-reviewed journal and we will develop an accessible summary of the results for website posting and stakeholder meetings.

Photographic measurement of upper-body sitting posture of high school students: a reliability and validity study.

BACKGROUND: All the reported measures of sitting posture, as well as photographs, have one flaw, as these measures are external to the body. These measures use calculations from external bony landmarks to estimate spinal posture, on the understanding that what is being measured externally reflects the shape, health and performance of structures of the underlying spine. Without a comparative measure of the relative position of the structures of the spine, the validity of any external spinal posture measure cannot be established. This paper reports on a study which tests the validity of photographs to measure adolescent sitting posture. METHODS: The study was conducted in a laboratory at the Department of Human Biology, University of Cape Town. A random sample of 40 adolescents were recruited from the Cape metropolitan schools, to detect differences of three degrees or more between the repeated measures of upright, normal or slouched posture (photographs) and between the posture photographs and LODOX measures. Eligible participants were healthy male and female subjects aged 15 or 16 years old, in Grade 10, and who were undertaking Computer or Computype studies at their schools. Two posture measurement tools were used in the study, namely: Photographs were taken using the Photographic Posture Analysis Method (PPAM) and Radiographs were taken using the LODOX (LODOX (Pty) Ltd) system. Subjects' posture was assessed in simulated computer workstations. The following angles were measured: the sagittal head angle, cervical angle, protraction/retraction angle, arm angle and the thoracic angle. RESULTS: Data from 39 subjects (19 males, 20 females) was used for analysis (17 15-year-olds (7 boys and 10 girls), 22 16-year-olds (12 boys and 10 girls)). All but one photographic angle showed moderate to good correlation with the LODOX angles (Pearson r values 0.67-0.95) with the exception being the shoulder protraction/retraction angle Pearson r values. Bland Altman limits of agreement illustrated a slight bias for all angles. The reliability study findings from repeated photographs demonstrated moderate to good correlation of all angles (ICC values 0.78-0.99). CONCLUSION: The findings of this study suggest that photographs provide valid and reliable indicators of the position of the underlying spine in sitting. Clinically it is important to know whether a patient is showing true progression in relation to a postural intervention. Based on the results of this study, the PPAM can be used in practice as a valid measure of sitting posture.

Does a prototype 'Experimental' chair facilitate more postural changes in computing adolescents compared to a normal school chair?

BACKGROUND: Prolonged sitting, such as when computing, has been linked to adolescent spinal pain. A chair should fit the user's body dimensions and aid the user in frequently changing sitting posture, rather than support one 'ideal' posture. Such a chair is not currently available to high school learners. OBJECTIVES: To develop a novel experimental school chair. To determine whether the experimental chair encourages regular small range movement in all directions whilst students work at computers in class. To compare the number of postural changes between the normal static school chair and the experimental chair, whilst students do computing work. METHODS: A development and validation study was conducted. Twelve high school students were randomly selected from a conveniently selected school. Fifteen minutes of 3D posture measurements were collected in both the prototype and school computer chair. The analysis focused on the frequency of postural movement. RESULTS: Data of eleven learners were analysed. There were statistically significant increases in the number of postural changes on the 'Experimental' chair compared to the school chair, for both pelvic side-flexion and pelvic rotation (ρ= 0.01). CONCLUSION: The experimental chair provided more postural movements when compared to the school computer chair. Future studies should use this experimental chair to determine the effect of increased postural movement, of especially the pelvis, on the prevalence and intensity of musculoskeletal symptoms of high school learners in the Cape Metropole area, Western Cape, South Africa.

The effect of vision on knee biomechanics during functional activities - A systematic review.

OBJECTIVES: The objective of this study was to assess the effect of occluded vision on lower limb kinematics and kinetics of the knee joint during functional tasks including drop landing (single or double leg), squatting (single or double leg), stepping down, cutting movement and hopping in healthy individuals, or individuals who had an ACL reconstruction or deficiency with no vision impairments. DESIGN: A systematic review was conducted. METHODS: A systematic review was conducted and electronic databases were searched between March 2012 and April 2013 for eligible papers. Methodological quality of each study was assessed using the Downs and Black revised checklist. RESULTS: Six studies met the eligibility criteria and a wide variation in methodological approaches was reported. This small evidence base indicated equivocal evidence about the effect of vision on knee biomechanics in individuals with healthy and compromised somatosensory function post an ACL reconstruction or injury. CONCLUSIONS: Clinicians should consider innovative, individualised ACL rehabilitation strategies when prescribing exercises which involve visual occlusion. Further research to increase the relatively small evidence base for the effect of vision on knee biomechanics is warranted.

The anthropometric match between high school learners of the Cape Metropole area, Western Cape, South Africa and their computer workstation at school.

STUDY DESIGN: Descriptive study. OBJECTIVE: The objective of this study was to present anthropometric data from high school students in Cape Metropole area, Western Cape, South Africa that are relevant for chair design and whether the dimensions of computer laboratory chairs currently used in high schools match linear anthropometrics of high-school students. Summary of Background Data. Learner-chair mismatch is proposed as a cause of poor postural alignment and spinal pain in adolescents. A learner-chair mismatch is defined as the incompatibility between the dimensions of a chair and the anthropometric dimensions of the learner. Currently, there is no published research to ascertain whether the furniture dimensions in school computer laboratories match the anthropometrics of the students. This may contribute to the high prevalence of adolescent spinal pain. METHODS: The sample consisted of 689 learners, 13-18 years old. The following body dimensions were measured: stature, popliteal height, buttock-to-popliteal length and hip width. These measurements were matched with the corresponding chair seat dimensions: height, depth and width. Popliteal and seat height mismatch was defined when the seat height is either >95% or <88% of the popliteal height. Buttock-popliteal length and seat depth mismatch was defined when the seat depth is either >95% or <80% of the buttock-popliteal length. Seat width mismatch is defined where the seat width should be at least 10% and at the most 30% larger than hip width. RESULTS: An 89% of learners did not match the seat. Five percent of learners matched the chair depth, the majority was found to be too big. In contrast, 65% of the learners matched the chair width dimension. CONCLUSIONS: A substantial mismatch was found. The school chairs failed standard ergonomics recommendations for the design of furniture to fit the user. This study supports the conclusion that there is no one-size-fits-all solution. There is an urgent need for chairs that are of different sizes or that are adjustable.
