Therapeutic lateral knee joint muscle taping potentially offers a low-risk, economical and effective alternative for the clinical treatment of light to moderate knee overload, due to misalignment in patients with genu varum. In this study, we aimed at investigating the immediate effect of lateral knee joint muscular kinesio taping on lower limb joint powers, during the stance phase of walking, in individuals with genu varum.
Fifteen male subjects with genu varum misalignment (age: 24.2±3.7 years) participated in the study. Subjects performed three walking trials without, and three with, biceps femoris and vastus lateralis kinesio taping. The three-dimensional position coordinate data of reflective markers were collected at 100 Hz using a six-cameras Vicon system (Motion Analysis Corp., UK). Additionally, two Kistler force plates (Kistler AG, Winterthur, Switzerland) were used to record the Ground Reaction Forces (GRF) components at 1000 Hz during stance phase of walking. A three-way ANOVA with post-hoc testing (using paired samples Student's t-test with Bonferroni correction) was performed to compare the power values of lower limb joints before and after the use of KT.
With kinesio taping, we observed that the average negative power increased at the ankle level in dominant limb, (P<0.05, 10-20% of gait cycle, GC), and at the knee level in both limbs (10-20% and 60-80% GC). Further, average negative power of the non-dominant knee joint (80-100% GC) and positive power of the non-dominant hip joint (60-80% GC) significantly reduced (P<0.05) in kinesio taping condition.
The biomechanical analysis of joint power during walking using kinesio taping provided essential information about the possible mechanisms involved in gait analysis with this intervention in adults with genu varus.
对于膝内翻患者因关节排列不齐导致的轻至中度膝关节负荷过重，治疗性外侧膝关节肌肉贴扎可能提供一种低风险、经济且有效的临床治疗替代方案。在本研究中，我们旨在调查外侧膝关节肌肉肌内效贴扎对膝内翻个体步行站立期下肢关节功率的即时影响。
15名患有膝内翻排列不齐的男性受试者（年龄：24.2±3.7岁）参与了本研究。受试者进行了三次未贴扎股二头肌和股外侧肌肌内效贴扎的步行试验，以及三次贴扎后的步行试验。使用六台摄像机的Vicon系统（英国运动分析公司）以100Hz的频率收集反光标记的三维位置坐标数据。此外，在步行站立期使用两个Kistler测力台（瑞士温特图尔的Kistler公司）以1000Hz的频率记录地面反作用力（GRF）分量。进行了一项带有事后检验的三因素方差分析（使用配对样本学生t检验并进行Bonferroni校正），以比较使用肌内效贴扎前后下肢关节的功率值。
通过肌内效贴扎，我们观察到优势侧下肢踝关节水平的平均负功率增加（P<0.05，步态周期的10-20%），以及双下肢膝关节水平的平均负功率增加（步态周期的10-20%和60-80%）。此外，在肌内效贴扎条件下，非优势侧膝关节的平均负功率（步态周期的80-100%）和非优势侧髋关节的正功率（步态周期的60-80%）显著降低（P<0.05）。
使用肌内效贴扎对步行过程中的关节功率进行生物力学分析，为该干预措施用于成人膝内翻步态分析的可能机制提供了重要信息。
