Background: Chronic ankle instability is common among basketball players, leading to repeated lateral sprains, impaired proprioception, balance deficits, and persistent pain. Rehabilitation typically emphasizes proprioceptive, neuromuscular, and balance training to restore function and prevent recurrence. However, the strategy of restricting healthy‑side movement to intensify neuromuscular focus on the affected limb has received little attention. This study therefore investigated whether balance and stabilization exercises incorporating healthy‑side movement restrictions could yield superior improvements in dynamic balance, reduce ankle instability, and alleviate pain in amateur basketball players with chronic lateral ankle instability. Methods: The participating subjects were 30 amateur basketball players in Daegu with chronic ankle instability. The subjects were randomized into the experimental (n=15) and control groups (n=15). The experimental group performed balance and stabilization exercises using healthy side restrictions, while the control group performed them without restrictions. The exercise was conducted three times a week for four weeks. The YBT was used to measure balance ability and the CAIT was used to measure ankle instability. Results: Both groups demonstrated significant within‑group improvements in YBT reach distances, enhanced CAIT scores, and reduced VAS pain ratings (p < .05). Notably, the experimental group achieved significantly greater gains in composite reach scores, larger increases in CAIT scores indicating reduced instability, and more pronounced pain reductions compared to the control group (p < .05). Conclusion: Incorporating healthy‑side movement restrictions into balance and stabilization training produces superior enhancements in functional balance, proprioceptive stability, and pain relief in basketball players with chronic ankle instability. This novel approach may augment existing rehabilitation protocols, offering a targeted strategy to prevent recurrence and optimize lower‑limb function.
