前言：Kenzo Kase 博士於25年前在日本所發明的肌內效貼布(kinesio tex tape)近幾年在台灣被廣泛應用於復健治療上。然而目前仍缺乏足夠的證據了解貼紮之後在神經肌肉學及生物力學上所產生的變化。因此本研究的目的即在探討貼紮對膝關節的影響。
材料及方法：由醫院員工徵求自願的健康成年人參與本研究。依據Kenzo Kase 博士針對退化性膝關節炎所建議的標準貼紮法，分別對受試者的兩側膝關節貼紮，同時於貼紮前及貼紮後第三天進行一系列的評估。利用Biodex等速肌力測量儀( Biodex system 3 Isokinetic Dynanometer) 分別檢測角速度60°/s及120°/s下的等速肌力及關節活動度，同時評估15°/45°主動及被動關節復位角度來代表本體感覺的表現。此外，利用起身行走(timed up and go test)及閉眼單腳站立測試(single leg stance test)進行平衡功能的評估。使用統計套裝軟體SPSS 10.0版做統計分析及處理，p<0.05代表統計學上的差異。
結果：共有11位健康受試者參與本實驗，包括位7位女性4位男性；平均年齡為26.48±6.64歲；平均身高為161.27±5.95cm；平均體重為61.27±14.79Kg；平均身體質量指數(BMI)為23.37±4.44Kg/m2。貼紮後非慣用腳於角速度60°/s及120°/s的情況下，膝關節彎曲力矩及功率(knee flexor moment and power)的增加達到統計學上的意義(60°/s：p=0.037；120 °/s：p=0.028)。膝關節關節活動角度及本體感覺則未因貼紮而產生顯著的差異。歩態平衡功能的測試中，起身行走測試由5.62±0.49s進步到5.42±0.57s (p=0.021)。此外，貼紮後股四頭肌的疲勞(work fatigue)程度明顯上升(p=0.006)。
結論：根據本研究的結果我們發現肌內效貼紮的確可以增加健康成年人的肌力，同時還可維持膝關節的活動度，因此推測肌內效貼紮應可作為輔助肢體障礙者執行日常生活活動的另一種治療。未來的我們將應用肌內效貼紮於因退化性膝關節炎導致肌力下降、日常生活活動限制的病患，並進一歩探討肌內效貼紮對退化性膝關節炎的效益。

Introduction：Developed by Dr. Kenzo Kase nearly 25 years ago in Japan, Kinesio taping is now widely used by rehabilitation professionals throughout Taiwan in recent years. Nevertheless, there are few studies assessing the neuromuscular and biomechanical changes following this taping procedure. The main purpose of this study was to demonstrate and analyze the effects of Kinesio taping on knee joint.
Materials and Methods：In this study, we recruited healthy volunteers with the similar age from hospital staff. Standard taping procedure for knee osteoarthritis, according to methods proposed by Dr. Kenzo Kase, was applied to bilateral knees. Serial evaluation of the biomechanical changes brought by this knee tape was performed both before and 3 days after this application. All isokinetic tests were performed using a Biodex system 3 Isokinetic Dynanometer. We assessed functional parameters and influences of the Kinesio taping method on muscle strength, proprioception, ROM of knee joints. Maximal isokinetic knee muscle strength was measured using preset angular velocities of 60°/s and 120°/s of concentric actions for knee. Changes in proprioceptive performance resulting from this taping method was recorded. Variations or improvement in knee ROM and function were determined by using single leg stance test and timed up and go test. The statistical analysis was carried out using an SPSS package(version 10.0). The significance was set at p< 0.05.
Results：There are 11 healthy volunteers (7 women and 4 men) included in this study, mean age：26.48±6.64years-old; mean body height：161.27±5.95cm; mean body weight 61.27±14.79Kg; mean Body Mass Index(BMI)：23.37±4.44Kg/m2. This taping procedure can improve knee flexor moment and power at non-dominant side, especially noted at angular velocities of 60°/s and 120 °/s (60°/s：p=0.037；120 °/s：p=0.028). No significant difference was found in proprioception and ROM of knee joints between tape and no tape. The timed up and go test was reduced from 5.62±0.49s to 5.42±0.57s (p=0.021). Moreover, after taping, the work fatigue of quadriceps at dominant side was significantly increased(p=0.006).
Conclusions： Based on the results obtained in this study, Kinesio taping is an operative management in improving knee muscle strength in healthy people. In addition, this taping procedure might be helpful in maintaining full range of motion, enabling individuals with disabilities to participate in physical activity in the community and at home with more functional assistance. Further research is required to determine the benefit or impact of the Kinesio taping method on patients with knee osteoarthritis.
