太极拳运动致髌股疼痛综合征的康复评估研究

Evaluation of Patellofemoral Pain Syndrome In Tai Chi practitioners

目的针对太极拳运动致髌股疼痛综合征进行评估和分析。方法对于北京体育大学武术学院的30名学生进行关节活动度和等速肌力的检查,对比出现膝关节疼痛和无疼痛的下肢生物力学特点。结果关节活动度方面:实验组髋关节外展(P<0.05)和内收(P<0.01)活动度左右侧差异有统计学意义;实验组踝关节关节活动度左右侧背屈差异有统计学意义(P<0.05),其余差异均无统计学意义。实验组和对照组相比较,左侧踝背屈关节活动度差异有统计学意义(P<0.05),其余差异均无统计学意义。肌力方面:实验组和对照组比较,在屈膝时右膝力量相差较大,差异有统计学意义(P<0.05),其余差异均无统计学意义。结论大腿前群和后群肌力不平衡,从而使得膝关节负荷增大,以及髋关节屈曲和外旋活动度的不足而导致大腿内收膝关节外翻等动作是髌股疼痛综合征产生的主要生物力学机制。

Objective To evaluate and analyze the patellofemoral pain syndrome（ PPS） in Tai Chi practitioners. Methods We checked range of motion and muscle strength of the 30 martial athletes from Beijing sports universit,and compared the condition of knee pain and no pain. Results At the range of motion,the left and right side of hip had significant difference at the abduction（ P〈0. 05） and adduction（ P〈0. 01）. Ankle-dorsiexion also showed significant difference（ P〈0. 05）,while the rest were not significant. Compare of the experimental group and control group showed dorsiflexion has significant difference（P〈0. 05）,while the rest were not significant. The experimental group and control group has significant difference about knee flexion（ P〈0. 05）. The rest were not significant. Conclusion The group of muscle is imbalance at the sagittal plane and make the knee joint load increase. The deficiency of hip flexion and extorsion activity cause the mistake movements of hip adduction and knee eversion which is the main biomechanical mechanism of patellofemoral pain syndrome.
