Ankle vs. Hip vs. Combined Strengthening in Chronic Ankle Instability

Chronic ankle instability (CAI) is a common condition that can develop after a lateral ankle sprain. Up to 40% of people who sprain their ankle experience a recurrence within a year, and as many as 30% develop persistent symptoms such as ankle "giving way," weakness, or instability. These symptoms can limit daily activities, sports participation, and increase the risk of future sprains. Muscle weakness in both the ankle and hip has been identified as an important factor contributing to CAI. Strengthening these muscles may therefore help improve stability and function. The SHAC study is a randomized controlled trial designed to compare three different strengthening programs in people with chronic ankle instability: (1) an ankle-focused strengthening program, (2) a hip-focused strengthening program, and (3) a combined ankle-hip strengthening program. The goal is to determine which approach leads to the greatest improvement in functional ability, muscle strength, balance, and ankle mobility. A total of 45 participants aged 18 to 35 years with documented chronic ankle instability will be recruited from local sports clubs and the University of Liège. All participants must have a history of at least one ankle sprain that occurred more than 12 months before entering the study, report episodes of ankle instability in the previous six months, and meet specific questionnaire criteria (CAIT \< 24 and FAAM Sport \< 80%). People with recent injuries, previous lower-limb surgery, fractur…
