不同治疗时间以等速肌力训练为主的综合疗法对膝骨关节炎的疗效对比

目的：研究等速肌力训练为主、结合玻璃酸钠关节腔注射及关节松动术的综合疗法改善膝骨关节炎疼痛及生活能力的疗效。方法采用随机数字表法将55例膝骨关节炎患者分为观察组和对照组，观察组给予等速肌力训练为主，结合玻璃酸钠关节腔注射及关节松动术治疗的综合疗法，对照组仅指导患者进行家庭自我踝泵训练，并按照试验方案定期复查。在治疗前，治疗4、8周后，分别采用视觉模拟评分法（VAS）、WOMAC简明健康调查量表进行患膝疼痛及日常生活能力状况的疗效评估。结果治疗源周后，观察组膝关节疼痛的VAS、WOMAC评分较治疗前及对照组明显下降（P＜0.05）；治疗8周后，观察组膝关节疼痛的VAS、WOMAC评分呈持续下降趋势，且较对照组明显下降（P＜0.05）；对照组治疗4周后的VAS、WOMAC评分与治疗前比较差异无统计学意义，治疗8周后的VAS、WOMAC评分与治疗前、治疗4周后比较差异有统计学意义（P＜0.05）。结论随着治疗时间的延长，以等速肌力训练为主，结合玻璃酸钠关节腔注射及关节松动术的综合疗法对缓解膝骨关节炎患膝疼痛、改善日常生活能力具有更好的治疗效果。

Effect comparison of different treatment time using combination therapy based upon isokinetic musle strength training on patients with knee osteoarthritis

Objective To investigate the effects of combination therapy including isokinetic muscle strength training,in-tra-articular injection of sodium hyaluronate and joint mobilization to improve pain and life skills on patients with knee osteoarthritis. Methods 55 patients with knee osteoarthritis were divided into the observation group and the control group by using random digit table.The observation group was treated with isokinetic muscle strength training,articular injection of sodium hyaluronate and joint mobilization treatment,while the control group only was given family guidance of self ankle pump training and periodic review in accordance with the test program.The visual analogue scale （VAS） score for pain and WOMAC condensed health survey were used to evaluate knee pain and daily living skills of the pa-tients before treatment and after 4 weeks,8 weeks treatment respectively. Results After 4 weeks treatment,knee pain VAS score and WOMAC score of the observation group than those before treatment and the control group was signifi-cantly decreased （P〈0.05）,after 8 weeks treatment,knee pain VAS score and WOMAC score of the observation group continued a downward trend （P〈0.05） and there was a statistical difference between the two groups （P〈0.05）. Above-mentioned score of the control group before treatment was compared with after 4 weeks treatment,and there was no sta-tistical difference （P＆gt;0.05）,above-mentioned score of the control group after 8 weeks treatment was compared with be-fore treatment and after 4 weeks treatment,and there was a statistical difference （P〈0.05）. Conclusion With the exten-sion of treatment time,combination therapy including isokinetic muscle strength training,intra-articular injection of sodium hyaluronate and joint mobilization has a better therapeutic effect to alleviate knee pain and improve daily living skills of patients with knee osteoarthritis.
