简要总结
This study aims to investigate the activity patterns of the peroneal muscle group, in individuals with a history of chronic ankle instability (CAI) of the ankle injuries compared with individuals without ankle problems. The study also aims to determine the effect of a targeted exercise programme on this muscle group in patients with CAI.
Research on this topic may provide important insight on the roles of these muscles in chronic ankle instability and investigate whether specific strengthening programmes are effective in this complex patient category.
详细描述
The purpose of this study is to evaluate the role of the peroneus brevis (PB) and peroneus longus (PL) muscles in patients with chronic ankle instability and to determine whether an eccentric- concentric focused training intervention has an effect on these muscles.
Volunteers will be recruited from Orthopaedic Clinics and the Musculoskeletal Assessment Clinics in St. Vincent's University Hospital. Posters and information leaflets will be supplied to areas where volunteers are being sought. A study information sheet will be given to the patient and written consent will be obtained prior to commencing the investigative study.
Inclusion Criteria The selection criteria for chronic ankle instability (CAI) patients will be based on the position statement of the International Ankle Consortium (Gribble et al. 2013).
- A history of at least 1 significant ankle sprain
- A history of the previously injured ankle joint "giving way", and/or recurrent sprain, and/or "feelings of instability". Self-reported ankle instability confirmed with validated ankle instability-specific questionnaire: The Cumberland Ankle Instability Tool (CAIT). CAIT is a simple, valid, and reliable tool to measure severity of functional ankle instability.
- A general self-reported foot and ankle function questionnaire is also completed. The Foot and Ankle Ability Measure (FAAM): The FAAM is a reliable, responsive, and valid measure of physical function for individuals with a broad range of musculoskeletal disorders of the lower leg, foot, and ankle.

入选标准
- •The selection criteria for CAI patients will be based on the position statement of the International Ankle Consortium (2013).
- •A history of at least 1 significant ankle sprain
- •A history of the previously injured ankle joint "giving way", and/or recurrent sprain, and/or "feelings of instability". Self-reported ankle instability confirmed with validated ankle instability-specific questionnaire: The Cumberland Ankle Instability Tool. CAIT is a simple, valid, and reliable tool to measure severity of functional ankle instability (Hiller et al., 2006).
- •A general self-reported foot and ankle function questionnaire is also completed. The Foot and Ankle Ability Measure: The FAAM is a reliable, responsive, and valid measure of physical function for individuals with a broad range of musculoskeletal disorders of the lower leg, foot, and ankle (Carcia et al., 2008).
排除标准
- •Acute injury to musculoskeletal structures of other joints of the lower extremity in the previous 3 months that impacted joint integrity and function (ie, sprains, fractures), resulting in at least 1 interrupted day of desired physical activity
- •Any Neurological problem that would affect muscle function of the lower limb
- •Pregnant Women
- •Participants under 18 and over 65
结局指标
主要结局
Surface EMG
时间窗: Assessed on day one, prior to intervention and at week 7 to assess change from baseline in EMG following the six-week intervention. Results presented 6 months later post analyses.
Both participants with CAI and participants without ankle instability will undergo S-EMG assessment of the peroneus longus, peroneus brevis and tibialis anterior in both static and dynamic conditions in a university motion analysis laboratory (This assessment process will initially be piloted on a healthy volunteer) Muscle onset will be determined and S-EMG will also normalised to Max Voluntary Contraction (MVC) determining the magnitude of activation, during Single leg Stance, wobble-board standing, Walking, Calf-raise exercise, Tip-toe walking, jogging and a jump-landing task. Change in EMG will be assessed at week 7 following the six-week intervention.
次要结局
- The Cumberland Ankle Instability Tool (CAIT)(Assessed on day one, prior to intervention and at week 7 to assess change from baseline in CAIT following the six-week intervention. Results presented 6 months later post analyses.)
- The Foot and Ankle Ability Measure (FAAM)(Assessed on day one, prior to intervention and at week 7 to assess change from baseline in FAAM following the six-week intervention. Results presented 6 months later post analyses.)
