Problems related to ankle instability, decreased proprioceptive sensation, altered static and dynamic balance abilities are suggested as major representative factors that contribute to the recurrence of ankle sprains.
To assess the effect of a three-week intervention (intervention emphasizing diagonal eccentric contraction (IEDEC) and intervention of general exercise (IGE)) on static and dynamic balance abilities, ankle strength and joint position sense at pre- and post-intervention, and at two- and three-week post-intervention.
Twenty-five participants with ankle instability, including a history of ankle sprain and recurrent episodes of giving way, were enrolled in the study. They were randomly classified into the IEDEC group (n= 12) and the IGE group (n= 13). Dynamic balance was examined using the Y Balance Test, four-way ankle strength was measured, and the static balance was evaluated using the total displacement of the center of pressure (COP). To identify the joint position error, eversion and inversion of the ankle angle were measured.
The results revealed significant increases in ankle dynamic stability and strength at two and three weeks post-intervention (p< 0.05). Similarly, the total displacement of the COP differed significantly over time, with a higher COP during the initial measurement than at two and three weeks intervention (p< 0.05) General balance training with IEDEC can improve position sense during ankle inversion (p< 0.05).
General balance training with IEDEC improved the position sense of the inversion. Combined therapeutic intervention, such as with the manual technique, could be a beneficial approach to maximize the treatment effects.
踝关节不稳定、本体感觉下降以及静态和动态平衡能力改变等问题被认为是导致踝关节扭伤复发的主要因素。
评估为期 3 周的干预（强调对角偏心收缩的干预[IEDEC]和一般运动的干预[IGE]）对静态和动态平衡能力、踝关节力量和关节位置感觉的影响，在干预前、干预后以及干预后 2 周和 3 周进行评估。
共有 25 名踝关节不稳定的参与者（包括踝关节扭伤史和反复发作的踝关节不稳定）参加了这项研究。他们被随机分为 IEDEC 组（n=12）和 IGE 组（n=13）。使用 Y 平衡测试评估动态平衡，测量四向踝关节力量，使用压力中心总位移（COP）评估静态平衡。为了确定关节位置误差，测量了踝关节角度的外翻和内翻。
结果显示，干预后 2 周和 3 周时，踝关节动态稳定性和力量显著增加（p<0.05）。同样，COP 的总位移在时间上也有显著差异，初始测量时的 COP 高于干预后 2 周和 3 周时的 COP（p<0.05）。IEDEC 的一般平衡训练可以改善踝关节内翻时的位置感觉（p<0.05）。
IEDEC 的一般平衡训练可以改善内翻时的位置感觉。结合手法等综合治疗干预措施可能是最大限度发挥治疗效果的有益方法。
