髌骨肌贴对股四头肌肌力及膝关节疼痛的影响

Effect of McConnell Taping on the quadriceps muscle strength and patellofemoral pain

背景:在评价髌骨肌贴的疗效时,既往的等速肌力测试较少关注角速度变化对疼痛和肌力的影响。目的:应用等速肌力测试观察髌骨肌贴干预前后,髌股关节疼痛综合征患者的疼痛和股四头肌肌力变化。方法:选择34例髌股关节综合征患者,在应用髌骨肌贴前,采用多关节等速力量测试评估训练系统测试角速度60(°)/s和180(°)/s下的膝关节等速向心收缩肌力,包括峰力矩值、总作功值及平均峰力矩值,并给予目测类比评分;在应用髌骨肌贴后,再次测试角速度60(°)/s和180(°)/s下的膝关节等速向心收缩肌力,并给予目测类比评分。结果与结论:①目测类比评分:在60(°)/s角速度下,髌骨肌贴应用后的分值较应用前仅轻微下降(P>0.05);在180(°)/s角速度下,髌骨肌贴应用后的分值较应用前显著下降(P<0.05)。②等速向心收缩肌力:在60(°)/s角速度下,髌骨肌贴应用后的峰力矩值、平均峰力矩、总功较应用前稍增加,但差异无显著性意义;在180(°)/s角速度下,髌骨肌贴应用后的峰力矩值、平均峰力矩、总功较应用前显著增加(P<0.05)。表明髌骨肌贴可显著改善髌股关节综合征患者低负荷关节运动时的疗效。

BACKGROUND：There is little attention focused on the effect of isokinetic testing about the variation of angular velocity on pain and muscle strength in the evaluation of curative effect of McConnel taping. OBJECTIVE： To evaluate the changes of quadriceps muscle strength and perceived pain levels in patients with patelofemoral pain syndrome before and after corrective McConnel taping in isokinetic testing. METHODS：A total of 34 patients with patelofemoral pain syndrome were evaluated in isokinetic testing for concentric contraction muscular strength, including the maximum torque, the total work, and the average work in 60 （°）/s and 180 （°）/s angular velocity, before and after the interventions of McConnel taping. The visual analogue scale scores were recorded. RESULTS AND CONCLUSION： The visual analogue scale scores were slightly decreased in angular velocity of 60 （°）/s after obturation when compared to before obturation （P 〉 0.05）, while the scores were significantly decreased in angular velocity of 180 （°）/s （P 〈 0.05）. The maximum torque, the total work, and the average work were slightly increased after obturation, but showed no significant difference in angular velocity of 60 （°）/s （P 〉 0.05）, while significantly increased in 180 （°）/s angular velocity （P 〈 0.05）. McConnel taping significantly improves the curative effect in patients with patelofemoral pain syndrome under low load joint movement.
