肌力锻炼对髌骨劳损患者的疗效评价

目的：观察肌力锻炼对髌骨劳损的效果.方法：将40例有不同程度髌骨劳损的学生随机分为康复组和对照组.对照组练习站桩,康复组进行股四头肌力量练习,比较2组锻炼效果.结果：2组临床疗效评定中总有效率分别为85.0％和65.0％,差异无统计学意义（P＞0.05）.2组锻炼后临床症状总积分差异无统计学意义（P＞0.05）,2组膝部疼痛积分差异有统计学意义（P＜0.01）.2组锻炼后股四头肌峰力矩增长幅度差异有统计学意义（P＜0.01）.结论：肌力锻炼明显增强了患者的股四头肌力量,有效地缓解了髌骨劳损患者的症状.

The curative effect evaluation of muscle strength training on patients with patellar strain

Objective： To observe the effects of muscle strength training on patellar strain. Methods： Forty students with different agree patellar strain from physical education department were randomly divided into rehabilitation group and control group. The rehabilitation group and control group taken exercise by quadriceps isometric exercise and standing on the peg, respectively, the effects of two groups were compared. Results ：The total effective rates of two groups were 85.0% and 65.0%, respectively, the differece of which had no statistical significance（P 〉 O. 05）. The difference of the total scores of clinical symptoms in two groups had no statistical significance （P 〉 0.05）. The differences of the knee pain scores and quadriceps peak torque increasing in two groups had statistical Significance （P 〈0.01 ）. Conclusions： Muscle strength training can significantly strengthen quadriceps strength and alleviate the symptoms of patients with patellar strain.
