Abstract Objectives To determine if wearing an ankle brace or taping the ankle, compared to no brace or tape, improves proprioceptive acuity in people with a history of ankle sprain or functional ...ankle instability. Design Systematic review and meta-analysis. Methods Studies using controlled, cross-over designs whereby participants who had sprained their ankle at least once or had functional ankle instability, underwent some form of proprioceptive sensation testing with and without ankle brace or tape, were included. Proprioceptive acuity was reported for the ankle tape/brace condition and the condition where no tape or brace was worn. Meta-analysis was employed to compare proprioceptive acuity with and without ankle tape/brace. Results Eight studies were included in the review. Studies measured either sense of movement or sense of joint position. The mean differences in 19 of 32 comparisons were not significant. Of the remaining mean differences, 10 were positive, indicating better proprioceptive acuity in the taped/braced condition and 3 were negative, indicating poorer proprioceptive acuity. Overall, there was no significant effect with ankle tape/brace compared to the no tape/brace condition (mean difference: 0.08°, 95% CI: −0.39 to 0.55). This finding was consistent when the two aspects of proprioception (sense of movement or joint position) were considered separately. Conclusions The pooled evidence suggests that using an ankle brace or ankle tape has no effect on proprioceptive acuity in participants with recurrent ankle sprain or who have functional ankle instability.
Abstract Objectives To identify the predictors of chronic ankle instability after an index lateral ankle sprain. Design Systematic review. Methods The databases of MEDLINE, CINAHL, AMED, Scopus, ...SPORTDiscus, Embase, Web of Science, PubMed, PEDro, and Cochrane Register of Clinical Trials were searched from the earliest record until May 2013. Prospective studies investigating any potential intrinsic predictors of chronic ankle instability after an index ankle sprain were included. Eligible studies had a prospective design (follow-up of at least three months), participants of any age with an index ankle sprain, and had assessed ongoing impairments associated with chronic ankle instability. Eligible studies were screened and data extracted by two independent reviewers. Results Four studies were included. Three potential predictors of chronic ankle instability, i.e., postural control, perceived instability, and severity of the index sprain, were investigated. Decreased postural control measured by number of foot lifts during single-leg stance with eyes closed and perceived instability measured by Cumberland Ankle Instability Tool were not predictors of chronic ankle instability. While the results of one study showed that the severity of the initial sprain was a predictor of re-sprain, another study did not. Conclusions Of the three investigated potential predictors of chronic ankle instability after an index ankle sprain, only severity of initial sprain (grade II) predicted re-sprain. However, concerns about validity of the grading system suggest that these findings should be interpreted with caution.
Abstract Weakness of ankle dorsiflexion is the cardinal manifestation of CMT. We investigated if a 12-week progressive resistance dorsiflexion strengthening program was feasible, safe and beneficial ...in a 15-year-old girl with an axonal form of CMT. Training load was based on a dose-escalating percentage of one-repetition maximum, completed on three non-consecutive days each week. Outcomes included dynamometric foot strength, motor function and instrumented walking ability. At 12-weeks, dorsiflexion strength improved 56–72% and plantarflexion strength by 15–20%. Standing long jump increased by 16%, while balance and endurance did not. Walking ability improved for speed, cadence, step time and stride length. Compliance was high and there were no adverse events. This case suggests progressive strength training might be a feasible intervention to help foot weakness and disability in childhood CMT.
The private practice workforce in speech-language pathology (SLP) has grown considerably in recent years, but growth in student placements in this setting has not seen commensurate growth. This study ...investigated benefits and challenges reported by SLP private practitioners in facilitating student placements, strategies they used to manage challenges encountered, and their perceptions of impacts of placements on client services and practice income. A qualitative case study approach was used involving semi-structured interviews with five participants who had recently supervised student placements in their private practice. Transcripts were analysed using a deductive content analysis approach to coding. Codes were collapsed into sub-categories then categories pertaining to benefits, challenges and strategies used. Benefits to clients, private practitioners, their practice, the students and the profession broadly were identified. Challenges included finding time for supervision and managing under-performing students. Income was not affected by the placements. SLPs used a range of strategies to successfully manage the challenges. Four of the five participants expressed high levels of satisfaction with the placements. Participants felt that placements were beneficial to all involved with prior planning and strategies to manage any challenges and most plan to continue offering student placements.
This study was a systematic review with meta-analysis examining the efficacy of carbohydrate (CHO) ingestion compared with placebo (PLA) on endurance exercise performance in adults. Relevant ...databases were searched to January 2011. Included studies were PLA-controlled, randomized, crossover designs in which CHO ingestion not exceeding 8% and between 30 and 80 g/h during exercise of ≥1 h was evaluated via time trial (TT) or exercise time to exhaustion (TTE). The between-trial standardized mean differences effect size (ES) and pooled estimates of the effect of CHO ingestion were calculated. Of the 41,175 studies from the initial search, 50 were included. The ES for submaximal exercise followed by TT was significant (ES = 0.53; 95% CI = 0.37-0.69; P < 0.001) as was the ES for TT (ES = 0.30; 95% CI = 0.07-0.53; P = 0.011). The weighted mean improvement in exercise performance favored CHO ingestion (7.5 and 2.0%, respectively). TTE (ES = 0.47; 95% CI = 0.32-0.62; P < 0.001) and submaximal exercise followed by TTE (ES = 0.44; 95% CI = 0.08-0.80; P = 0.017) also showed significant effects, with weighted mean improvements of 15.1 and 54.2%, respectively, with CHO ingestion. Similar trends were evident for subanalyses of studies using only male or trained participants, for exercise of 1-3 h duration, and where CHO and PLA beverages were matched for electrolyte content. The data support that ingestion of CHO between 30 and 80 g/h enhances endurance exercise performance in adults.
Changes in lower limb haemodynamics such as arterial pressure and/or flow have often been, and continue to be, cited as possible mechanisms for the improvement in walking performance that occurs with ...exercise training in individuals with peripheral arterial disease (PAD), but data are conflicting in this regard. There are a small number of literature reviews examining the effects of exercise on PAD, however, there has been insufficient analysis synthesizing possible mechanisms of effect, overall benefits and limitations of these trials. Our objective was therefore to systematically review the evidence for the effect of exercise on lower limb haemodynamic measures of resting and post-exercise ankle brachial index (ABI), resting toe pressure, and resting and reactive hyperaemic calf blood flow in PAD. A systematic search of studies published between 1934 and March 2010 was conducted using MEDLINE, EMBASE, AMED, SportDiscus, CINAHL, PEDro, Premedline, Google Scholar and Web of Knowledge databases. Eligible studies included randomized controlled trials using an exercise intervention for the treatment of intermittent claudication with haemodynamic measures of disease severity as outcomes. Relative effect sizes (ESs) and 95% confidence intervals were calculated for outcomes. Correlation and regression analyses were performed to establish relationships between symptoms and haemodynamic outcomes. Thirty-three trials including 1237 subjects with mild to moderate claudication met the eligibility criteria. Exercise did not significantly change lower extremity haemodynamics in most trials; nor were clinical improvements related to changes in resting ABI (mean ES 0.09 +/- 0.26; r = 0.02; p = 0.94), post-exercise ABI (mean ES 0.18 +/- 0.3; r = -0.33; p = 0.52) or reactive hyperaemic calf blood flow (mean ES 0.38 +/- 0.67; r = 0.35; p = 0.26). A relationship may exist between a change in symptoms and changes in resting toe pressure (mean ES 0.22 +/- 0.22; r = 0.75; p = 0.25) and resting calf blood flow (mean ES 0.09 +/- 0.16; r = 0.59; p = 0.22). Changes in resting and post-exercise ABI and reactive hyperaemic calf blood flow do not appear to explain the clinical benefits of exercise in PAD. More study is required in the areas of resting toe pressure and resting calf blood flow.
ABSTRACT
Introduction: Biomarkers of disease severity in Charcot–Marie–Tooth disease (CMT) are required to evaluate early responses to treatment. In this study we used magnetic resonance imaging ...(MRI) to evaluate the relationship between muscle volume and intramuscular fat accumulation with weakness, disability, and impaired gait in affected children and adolescents. Methods: Fifty‐five participants underwent MRI of the anterior compartment of the lower leg. Muscle and fat volumes were calculated. Strength was measured using hand‐held dynamometry, disability using the CMT Pediatric Scale, and 3‐dimensional gait analysis using an 8‐camera Vicon Nexus motion capture system. Results: Lower muscle volume was significantly associated with reduced dorsiflexion strength, increased disability, impaired gait profile score, and foot drop. Intramuscular fat accumulation was associated with reduced dorsiflexion strength and impaired gait profile score. Discussion: The MRI protocol described was feasible, reliable, and sensitive to the magnitude of weakness, disability, and walking difficulties in children with CMT. Muscle Nerve 59:213–217, 2019
Objective
To compare different methods of assessing energy expenditure (EE) and physical activity (PA) in people with spinal cord injury (SCI) under community-dwelling conditions.
Methods
A reference ...standard encompassing the doubly labelled water (DLW) technique, heart rate monitoring (FLEX-HR), a multi-sensor armband (SenseWear Armband (SWA)), and two PA recall questionnaires were employed in 14 people with SCI to estimate EE and leisure-time PA.
Results
Mean total daily energy expenditure (TDEE) assessed by DLW, FLEX-HR, and SWA were 9817 ± 2491 kJ/day, 8498 ± 1516 kJ/day, and 11414 ± 3242 kJ/day, respectively. Physical activity energy expenditure (PAEE) quantified by DLW was 2841 ± 1626 kJ/day, 2935 ± 1732 kJ/day estimated from FLEX-HR, and 2773 ± 2966 kJ/day derived from SWA. After converting the PA recall questionnaire data to EE in kJ/day, PAEE for the Physical Activity Recall Assessment for People with Spinal Cord Injury (PARA-SCI) was 2339 ± 1171 kJ/day and for Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) 749 ± 1026 kJ/day. DLW-quantified PAEE was moderately associated with PARA-SCI (R
2
= 0.62, P < 0.05), but not with the other estimates of PAEE (R
2
ranged between 0.13 and 0.30, P > 0.05).
Conclusion
Our findings revealed that the PARA-SCI recall questionnaire was the best estimate of PAEE compared to the reference standard DLW approach. Although the between-method variability for SWA, FLEX-HR, and PASIPD-derived PAEE was small, there was a weak association between these methods and the criterion DLW technique. The best estimate of DLW-quantified TDEE was by FLEX-HR. SWA significantly overestimated TDEE in this population.
Abstract Background Clinical decision-making regarding diagnosis and management largely depends on comparison with healthy or ‘normal’ values. Physiotherapists and researchers therefore need access ...to robust patient-centred outcome measures and appropriate reference values. However there is a lack of high-quality reference data for many clinical measures. The aim of the 1000 Norms Project is to generate a freely accessible database of musculoskeletal and neurological reference values representative of the healthy population across the lifespan. Methods/design In 2012 the 1000 Norms Project Consortium defined the concept of ‘normal’, established a sampling strategy and selected measures based on clinical significance, psychometric properties and the need for reference data. Musculoskeletal and neurological items tapping the constructs of dexterity, balance, ambulation, joint range of motion, strength and power, endurance and motor planning will be collected in this cross-sectional study. Standardised questionnaires will evaluate quality of life, physical activity, and musculoskeletal health. Saliva DNA will be analysed for the ACTN3 genotype (‘gene for speed’). A volunteer cohort of 1000 participants aged 3 to 100 years will be recruited according to a set of self-reported health criteria. Descriptive statistics will be generated, creating tables of mean values and standard deviations stratified for age and gender. Quantile regression equations will be used to generate age charts and age-specific centile values. Discussion This project will be a powerful resource to assist physiotherapists and clinicians across all areas of healthcare to diagnose pathology, track disease progression and evaluate treatment response. This reference dataset will also contribute to the development of robust patient-centred clinical trial outcome measures.
Chronic disease is prevalent in rural communities, but access to health care is limited. Allied health intervention, incorporating behaviour change and exercise, may improve health outcomes. PHYZ X ...2U is a new service delivery model incorporating face-to-face consultations via a mobile clinic and remote health coaching, delivered by physiotherapy and exercise physiology clinicians and university students on clinical placement, to provide exercise programs to people living with chronic disease in rural New South Wales, Australia. This pilot study evaluated the feasibility and acceptability of PHYZ X 2U by evaluating participants’ goal attainment, exercise, quality of life and behaviour change following participation in the 12-week program, and amount of health coaching received. Sixty-two participants with one or more chronic diseases set a total of 123 goals. Thirty-nine (63%) participants completed the program, with 59% of these achieving their goals and 43% progressing in their attitudes and behaviour towards exercise. Weekly exercise increased by 1h following program participation (P=0.02), but quality of life remained unchanged (P=0.24). Participants who completed the program received more health coaching than those lost to follow up. PHYZ X 2U can increase access to allied health for people with chronic disease living in rural and remote areas. Refining the service to maximise program adherence and optimally manage a broad range of chronic diseases is required.
