Twenty-two university students with unilateral functional instability of the ankle participated in this study. They were randomly assigned to one of two experimental groups. Subjects in both groups were trained to stand on the affected limb on an ankle disk. In group 1, two pieces of 1-cm wide nonelastic adhesive tape were applied to the skin around the lateral malleolus from the distal third of the lower leg to the sole of the foot before the training sessions. Subjects in group 2 participated in the training sessions without the application of the adhesive tape. Training was performed for 10 minutes a day, five times per week, for a period of 10 weeks. Subjects were tested for postural sway while standing on the affected limb before, during, and after the training period. In group 1, postural sway values decreased significantly after 4 weeks compared with the pretraining performance, and they were within the normal range after not more than 6 weeks of training. In group 2, the values did not improve significantly compared with the pretraining performance until after 6 weeks of training, and they were not within the normal range until after 8 weeks of training. The findings suggest that the 2-week earlier correction of postural sway in group 1 was due to an increased afferent input from skin receptors that were stimulated by the traction of the adhesive tape.
22名患有单侧踝关节功能性不稳定的大学生参与了本研究。他们被随机分配到两个实验组之一。两组受试者均接受在踝关节盘上患侧肢体站立的训练。在第1组中，在训练前，从小腿远端三分之一处至脚底，在外侧踝关节周围的皮肤上粘贴两条1厘米宽的无弹性胶带。第2组受试者在不粘贴胶带的情况下参加训练。训练每天进行10分钟，每周5次，为期10周。在训练期之前、期间和之后，对受试者在患侧肢体站立时的姿势摆动进行测试。在第1组中，与训练前相比，4周后姿势摆动值显著降低，且在不超过6周的训练后处于正常范围内。在第2组中，与训练前相比，直到训练6周后这些值才显著改善，且直到训练8周后才处于正常范围内。研究结果表明，第1组姿势摆动提前2周得到纠正，是由于胶带牵引刺激皮肤感受器增加了传入输入。
