Although the use of KT has increased considerably in the clinical practice in the last years, there is limited evidence about the effects of its application in proprioception.
The aim of this study was to determine the effect of KT on joint position sense and force sense on the wrist of healthy subjects.
Fifty-four subjects were analyzed in a randomized, crossover, single-blind study design. To determine the force sense, the subjects had to reach 50% of their maximum grip force. Wrist joint position sense was assessed during active repositioning tests at the target angles of 30° flexion and extension of wrist. A digital dynamometer was used to determine the sense of force and a digital goniometer was used to determine the joint position sense. Subjects were evaluated with KT (I- strip on ventral aspect of forearms from origin to insertion) and placebo (an inelastic tape was applied following the same procedure as KT).
No significant differences have been found in the force sense, neither in the comparisons between control and interventions (p=0.286), nor between pre and post-intervention (p=0.111). For wrist joint position sense, a statistically significant effect (p< 0.05) was found at 30º of extension between the control and experimental group in favor of the control group.
The application of KT did not produce changes in FS and only caused a significant improvement in JPS in extension (30º). The results appear to indicate that the application of KT to improve proprioception in healthy subjects should be reconsidered.
尽管 KT 在过去几年的临床实践中得到了广泛应用，但关于其在本体感觉中的应用效果的证据有限。
本研究旨在确定 KT 对健康受试者腕关节位置觉和力量觉的影响。
采用随机、交叉、单盲研究设计，对 54 名受试者进行分析。为了确定力量感，受试者必须达到其最大握力的 50%。腕关节位置觉在主动重定位测试中进行，目标角度为 30°腕关节屈伸。使用数字测力计确定力量感，使用数字关节角度计确定关节位置觉。受试者分别接受 KT（I 带置于前臂掌侧，从起点到止点）和安慰剂（弹性胶带按与 KT 相同的程序应用）处理。
在力量觉方面，无论是在对照组和干预组之间的比较（p=0.286），还是在干预前后的比较（p=0.111），均未发现显著差异。对于腕关节位置觉，在 30°伸展时，对照组和实验组之间存在统计学显著差异（p<0.05），对照组的结果更好。
KT 的应用并未改变 FS，仅在伸展（30°）时显著改善了 JPS。结果表明，在健康受试者中应用 KT 来改善本体感觉应重新考虑。
