BACKGROUND Ankle sprain reduces capacity for neurosensory information processing, and these patients commonly progress to chronic ankle instability (CAI). To address this problem, the short-foot exercise (SFE) may be used. However, there has been no previous research on the neurosensory impact of SFE. Therefore, the aim of this study was to assess improvement of quantitative neurosensory indicators after SFE and to determine the effect of proprioceptive sensory exercise (PSE) in patients with CAI. MATERIAL AND METHODS The present study included 30 adults (age range: 19-29 years; 50% female). Selection criteria for CAI (Cumberland Ankle Instability Tool £24) were implemented, and participants were randomly allocated to 2 groups: SFE (n1=15) and PSE (n2=15). Exercises were conducted 3 times per week for 8 weeks. Measurements of quantitative somatosensory of joint position sense and vibration sensory thresholds, dynamic balance, and ankle instability assessment were evaluated before and after completion of each intervention. Data were analyzed using a repeated- measures analysis of variance. RESULTS In a time-by-group comparison, the SFE group showed a more significant improvement with regards to eversion joint position sense (F1,28=4.543, p<0.05). For vibration sensory threshold, the SFE group showed a more significant improvement (F1,28=8.280, p<0.01). Balance index according to anterio-posterior, mediolateral, and overall index the SFE group a more significant improvement (F1,28=6.666, 4.585, 5.207, p<0.05). And ankle instability SFE group showed a more significant improvement (F1,28=6.890, p<0.05). CONCLUSIONS SFE is more effective than PSE for treating ankle sprain patients. There is a need to develop and promote an effective and controlled exercise program to facilitate the return of ankle sprain patients to normal daily life.
踝关节扭伤会降低神经感觉信息处理能力，这些患者通常会发展为慢性踝关节不稳定（CAI）。为了解决这个问题，可以使用短足运动（SFE）。然而，之前没有关于 SFE 对神经感觉影响的研究。因此，本研究旨在评估 SFE 后定量神经感觉指标的改善，并确定本体感觉感觉运动（PSE）在 CAI 患者中的效果。
本研究纳入了 30 名成年人（年龄范围：19-29 岁；50%为女性）。实施了 CAI（坎伯兰踝关节不稳定工具£24）的选择标准，参与者被随机分配到 2 组：SFE（n1=15）和 PSE（n2=15）。每周进行 3 次运动，共进行 8 周。在每次干预结束前后，评估定量关节位置感觉和振动感觉阈值、动态平衡和踝关节不稳定评估的定量躯体感觉。使用重复测量方差分析对数据进行分析。
在时间与组比较中，SFE 组在外翻关节位置感觉方面表现出更显著的改善（F1,28=4.543，p<0.05）。对于振动感觉阈值，SFE 组的改善更为显著（F1,28=8.280，p<0.01）。根据前-后、内-外侧和整体指数，SFE 组的平衡指数有更显著的改善（F1,28=6.666，4.585，5.207，p<0.05）。SFE 组的踝关节不稳定也有更显著的改善（F1,28=6.890，p<0.05）。
SFE 比 PSE 更有效地治疗踝关节扭伤患者。需要制定和推广有效的、受控制的运动方案，以帮助踝关节扭伤患者恢复正常的日常生活。
