Purpose: The purpose of the study was to investigate the effects of visual feedback exercise (VFE), sandal exercise (SE), and thera-band exercise (TE) on people with functional ankle instability. Methods: The 45 study participants were divided into three groups of 15. In the VFE group, participants performed short-foot exercises using visual feedback; the SE group performed sandal exercises, and the TE group performed thera-band exercises. Over a period of 8 consecutive weeks, the experimental groups exercised for 15 minutes per session, four times per week. Balance was measured using the Biodex Balance System for dynamic balance ability (overall balance index [OBI], mediolateral balance index [MBI], and anterioposterior balance index [ABI]). Vibration threshold sense (VTS) was assessed using a vibratory sensory analyzer. Ankle muscular strength was measured using the Biodex 4 Pro. The main outcome measures were assessed at baseline and after 8 weeks of training. Results: Significant improvements in dynamic balance were noted in all three groups (p < 0.05). Significant improvements in VTS and muscular strength were also noted in the VFE and TE groups but not in the SE group (p < 0.05). Conclusion: Appropriate environmental and situational mediation may be of great clinical significance for patients suffering from chronic ankle instability. It is hoped that the findings will inform a program for prevention of ankle instability.

The objective of the study was the effects of balance training using sandals on the balancing and proprioception of patients with chronic ankle instability(CAI). A total of 36 patients with CAI were assigned to sandal exercise(SE), balance training(BT), and control groups(CG). The groups were assessed for static balancing and proprioception before and after the intervention. The SE performed using balance sandals, while BT performed balance training. Intervention comprised a 30minute session. 3 times a week for 8 weeks. The SE showed significant effect in static balance, as compared to the other two groups (p<.001), whereas proprioception showed a significant effect on eversion (p<.001). Therefore, balance training using sandals can be a positive intervention method for prevention of falls in elderly as well as chronic ankle instability patients.
