Effects of hip strengthening on postural control and muscle strength in individuals with chronic ankle instability: A systematic review and meta-analysis of randomized controlled trials

Hip strengthening improves postural control and muscle strength in individuals with CAI. Notably, the application of hip strengthening combined with ankle rehabilitation training is beneficial for postural control, whereas standalone hip strengthening yields no additional benefits. However, these findings should be interpreted with caution due to the limited number of studies, small sample sizes, and low quality of the evidence.
