The objective of this study was to implement combined muscle strengthening and proprioceptive exercises to investigate the effects of combined exercises on functional ankle instability. Experiments were conducted with 30 adult males and females. The study subjects were separated at random into either a control group (Group A), a muscle strengthening exercise group (Group B), or a combined muscle strengthening and proprioceptive exercise group (Group C) consisting of 10 subjects each. In Group A, measurements were only conducted before and after the experiment without any intervention, whereas the exercise programs for Group B and Group C were implemented three days per week for four weeks. Muscle strength showed significant increases in Groups B and C compared with the control group during plantar flexion, dorsiflexion, inversion, and eversion. The Cumberland ankle instability tool showed significant increases in Group B and Group C compared with Group A and significant increases in Group C compared with Group B.
Applying combined muscle strengthening and proprioceptive exercises to individuals with functional ankle instability is more effective than the application of only muscle strengthening exercises.
