Effects of a 6-week intrinsic foot muscle exercise program on the functions of intrinsic foot muscle and dynamic balance in patients with chronic ankle instability
We aimed to evaluate the effects of a 6-week intrinsic foot muscle ex-ercise program on the activation of intrinsic foot muscle movement and dynamic balance in adults with chronic ankle stability. A total of 30 adults with chronic ankle instability were recruited. The participants were randomly assigned to a group performing intrinsic foot muscle ex-ercises and a control group doing no exercises. We measured the acti-vation rate and dynamic balance of the abductor hallucis, flexor digito-rum brevis, flexor hallucis brevis, and quadratus plantae before and af-ter the intervention. We found that the activation rate and dynamic bal-ance significantly increased in all intrinsic foot muscles in the experi-mental group. These results suggest that intrinsic foot muscle exercise for patients with chronic ankle stability is an effective treatment for im-proving the functions and balance ability of the intrinsic foot muscles.
