[Clinical study on improving the strength and activity of lumbar spine with Qiang Jin exercises].

Objective: To observe the effect of Qiang Jin exercises on the muscle strength and activity of lumbar spine in patients with lumbar disc herniation.

Methods: From March 2016 to September 2017, at the Department of Orthopaedics, Shuguang Hospital, Shanghai University of Traditional Chinese Medicine, a total of 110 subjects were enrolled, and 98 eligible subjects were screened. The subjects were randomized by stratified randomization and divided into experimental group and control group, 49 cases in each group, 25 males and 24 females in the experimental group, 25 males and 24 females in the control group. The experimental group exercised with Qiang Jin exercises, one time each morning and evening, each time10 sets were made;the control group used classic rehabilitation training, training twice a week, and three months was a course of treatment. After 12 weeks of training, the muscle strength and activity of the lumbar spine were evaluated and compared with the muscle strength and activity of the lumbar spine before training.

Results: The experimental group and the control group had different muscle strength and activity of the lumbar spine before and after treatment (<0.05). There was no significant difference between two groups after treatment(>0.05).

Conclusion: Qiang Jin exercises can effectively improve the muscle strength and activity of the lumbar spine and improve the daily living ability of patients.
