RESUMEN
OBJECTIVES: Evaluate if non-elite netballers sought health care, treatments received, and return-to-play decisions after an ankle sprain, including intercountry differences. DESIGN: Cross-sectional survey. METHODS: Non-elite netballers aged >14â¯years were recruited from Australia, United Kingdom, and New Zealand. Participants completed an online survey regarding their last ankle sprain and were queried regarding health care sought, health professionals consulted, treatments received, time missed, and return-to-play clearance. Data were described using number (proportion) for the overall cohort and countries. Between-country differences in health care use were compared using chi-square tests. Descriptive statistics were presented for management practices. RESULTS: We received 1592 responses from Australian (nâ¯=â¯846), United Kingdom (nâ¯=â¯454), and New Zealand (nâ¯=â¯292) netballers. Three in five (nâ¯=â¯951, 60â¯%) sought health care. Of those, most consulted a physiotherapist (nâ¯=â¯728, 76â¯%), received strengthening exercises (nâ¯=â¯771, 81â¯%), balance exercises (Nâ¯=â¯665, 70â¯%) and taping (nâ¯=â¯636, 67â¯%). Few received return-to-play clearance (nâ¯=â¯362, 23â¯%). Comparing countries, fewer United Kingdom netballers sought health care than Australian and New Zealand netballers (Australia: 60â¯% vs United Kingdom: 53â¯% vs New Zealand: 68â¯%, pâ¯<â¯0.001), consulted a physiotherapist (Australia: 79â¯%, United Kingdom: 63â¯%, New Zealand: 87â¯%), received strengthening (Australia: 84â¯%, United Kingdom: 73â¯%, New Zealand: 84â¯%) or balance exercises (Australia: 71â¯%, United Kingdom: 60â¯%, New Zealand: 80â¯%) or taping (Australia: 74â¯%, United Kingdom: 39â¯%, New Zealand: 82â¯%). More Australian netballers returned to play within 1-7â¯days (Australia: 25â¯%, United Kingdom: 15â¯%, New Zealand: 21â¯%) and fewer United Kingdom netballers received return-to-play clearance (Australia: 28â¯%, United Kingdom: 10â¯%, New Zealand: 28â¯%). CONCLUSIONS: Health-seeking behaviours are adopted by some, but not all netballers after an ankle sprain. For those who sought care, most consulted a physiotherapist and were prescribed exercise-based interventions and external ankle support, but few received return-to-play clearance. Comparing countries, United Kingdom netballers had lower health-seeking behaviours and received less best-practice management than Australian and New Zealand netballers.

OBJECTIVE: To evaluate the effects of biomechanical foot-based interventions (eg, footwear, insoles, taping and bracing on the foot) on patellofemoral loads during walking, running or walking and running combined in adults with and without patellofemoral pain or osteoarthritis. DESIGN: Systematic review with meta-analysis. DATA SOURCES: MEDLINE, CINAHL, SPORTdiscus, Embase and CENTRAL. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: English-language studies that assessed effects of biomechanical foot-based interventions on peak patellofemoral joint loads, quantified by patellofemoral joint pressure, reaction force or knee flexion moment during gait, in people with or without patellofemoral pain or osteoarthritis. RESULTS: We identified 22 footwear and 11 insole studies (participant n=578). Pooled analyses indicated low-certainty evidence that minimalist footwear leads to a small reduction in peak patellofemoral joint loads compared with conventional footwear during running only (standardised mean difference (SMD) (95% CI) = -0.40 (-0.68 to -0.11)). Low-certainty evidence indicated that medial support insoles do not alter patellofemoral joint loads during walking (SMD (95% CI) = -0.08 (-0.42 to 0.27)) or running (SMD (95% CI) = 0.11 (-0.17 to 0.39)). Very low-certainty evidence indicated rocker-soled shoes have no effect on patellofemoral joint loads during walking and running combined (SMD (95% CI) = 0.37) (-0.06 to 0.79)). CONCLUSION: Minimalist footwear may reduce peak patellofemoral joint loads slightly compared with conventional footwear during running only. Medial support insoles may not alter patellofemoral joint loads during walking or running and the evidence is very uncertain about the effect of rocker-soled shoes during walking and running combined. Clinicians aiming to reduce patellofemoral joint loads during running in people with patellofemoral pain or osteoarthritis may consider minimalist footwear.

OBJECTIVE: To systematically review the literature to determine whether external ankle supports influence ankle biomechanics in participants with chronic ankle instability (CAI) during sport-related tasks. DATA SOURCES: A literature search of MEDLINE, SPORTDiscus, and CINAHL databases was conducted in November 2021. STUDY SELECTION: Included studies were randomized crossover or parallel-group controlled trials in which researchers assessed ankle biomechanics during landing, running, or change of direction in participants with CAI using external ankle supports compared with no support. DATA EXTRACTION: Two authors independently identified studies, extracted data, and assessed risk of bias (Cochrane risk-of-bias tool version 2) and quality of evidence (Grading of Recommendations Assessment, Development and Evaluation). Random-effects meta-analysis was used to compare between-groups mean differences with 95% CIs. Grading of Recommendations Assessment, Development and Evaluation recommendations were used to determine the certainty of findings. DATA SYNTHESIS: A total of 13 studies of low to moderate risk of bias were included. During landing, very low-grade evidence indicated external ankle supports reduce frontal-plane excursion (mean difference [95% CI] = -1.83° [-2.97°, -0.69°], P = .002), plantar-flexion angle at initial contact (-3.86° [-6.18°, -1.54°], P = .001), and sagittal-plane excursion (-3.45° [-5.00°, -1.90°], P < .001) but not inversion angle at initial contact (-1.00° [-3.59°, 1.59°], P = .45). During running, very low- to low-grade evidence indicated external ankle supports reduce sagittal-plane excursion (-5.21° [-8.59°, -1.83°], P = .003) but not inversion angle at initial contact (0.32° [-2.11°, 1.47°], P = .73), frontal-plane excursion (-1.31° [-3.24°, 0.63°], P = .19), or plantar-flexion angle at initial contact (-0.12° [-3.54°, 3.29°], P = .94). Studies investigating changes of direction were insufficient. CONCLUSIONS: Very low-grade evidence indicated external ankle supports reduce frontal-plane excursion but not inversion angle at initial contact in participants with CAI during landing. Limiting frontal-plane excursion may reduce ankle-sprain risk. Frontal-plane ankle kinematics were not influenced by external ankle supports during running. Sagittal-plane reductions were observed with external ankle supports during landing and running with low to very low certainty, but their influence on ankle-sprain risk is undetermined.

BACKGROUND: Patellofemoral pain is highly prevalent across the lifespan, and a significant proportion of people report unfavourable outcomes years after diagnosis. Previous research has implicated patellofemoral joint loading during gait in patellofemoral pain and its sequelae, patellofemoral osteoarthritis. Biomechanical foot-based interventions (e.g., footwear, insoles, orthotics, taping or bracing) can alter patellofemoral joint loads by reducing motions at the foot that increase compression between the patella and underlying femur via coupling mechanisms, making them a promising treatment option. This systematic review will summarise the evidence about the effect of biomechanical foot-based interventions on patellofemoral joint loads during gait in adults with and without patellofemoral pain and osteoarthritis. METHODS: MEDLINE (Ovid), the Cumulative Index to Nursing and Allied Health Literature CINAHL, The Cochrane Central Register of Controlled Trials (CENTRAL), SPORTdiscus (EBSCO) and Embase (Ovid) will be searched. Our search strategy will include terms related to 'patellofemoral joint', 'loads' and 'biomechanical foot-based interventions'. We will include studies published in the English language that assess the effect of biomechanical foot-based interventions on patellofemoral joint loads, quantified by patellofemoral joint pressure, patellofemoral joint reaction force and/or knee flexion moment. Two reviewers will independently screen titles and abstracts, complete full-text reviews, and extract data from included studies. Two reviewers will assess study quality using the Revised Cochrane Risk of Bias (RoB 2) tool or the Cochrane Risk Of Bias In Non-Randomized Studies - of Interventions (ROBINS-I) tool. We will provide a synthesis of the included studies' characteristics and results. If three or more studies are sufficiently similar in population and intervention, we will pool the data to conduct a meta-analysis and report findings as standardised mean differences with 95% confidence intervals. If a meta-analysis cannot be performed, we will conduct a narrative synthesis of the results and produce forest plots for individual studies. DISCUSSION: This protocol outlines the methods of a systematic review that will determine the effect of biomechanical foot-based interventions on patellofemoral joint loads. Our findings will inform clinical practice by identifying biomechanical foot-based interventions that reduce or increase patellofemoral joint loads, which may aid the treatment of adults with patellofemoral pain and osteoarthritis. TRIAL REGISTRATION: Registered with PROSPERO on the 4th of May 2022 (CRD42022315207).

BACKGROUND: Ankle sprains are the most commonly reported injury in netball. Approximately four in five netball athletes will sustain an ankle sprain, up to half will go on to sustain recurrent ankle sprains, and nine in ten report perceived ankle instability. Historically, prevention and management strategies of ankle sprains and injuries have been investigated for a variety of sports, however, no literature reviews have investigated these in netball athletes, or compared these with current best-practice within the literature. Therefore, this scoping review aims to understand how netball athletes currently prevent and manage ankle sprains and to compare these approaches with best-practice recommendations. METHODS: A literature search was conducted using MEDLINE, CINAHL, and SPORTDiscus databases using keywords to capture studies with data or information related to the prevention and management of ankle sprains and injuries in netball. RESULTS: The search strategy captured 982 studies across all databases, with 30 netball studies included in this scoping review. Studies suggest netball athletes are not commonly referred to health professionals, do not undertake adequate rehabilitation, and almost immediately return to court following an ankle sprain or injury. Current best-practices suggest injury prevention programs and external ankle support effectively reduce ankle sprains and injuries; however, poor compliance and implementation may be a significant barrier. Currently, there is a lack of evidence that netball-specific footwear reduces the risk of ankle sprains. CONCLUSION: The findings suggest netball athletes do not implement current best-practice prevention and management strategies following an ankle sprain. This is despite evidence of the effectiveness of injury prevention programs, external ankle support, and adequate rehabilitation in reducing ankle sprain rates. Current-best practice prevention and management of ankle sprains should be considered by clinicians, coaches, and athletes to reduce the prevalence and chronicity of ankle sprains in netball.
