To investigate the “Weishi” functional exercise in the treatment of lumber disc herniation(LDH).Methods: One hundred and eighty-nine patients with LDH were randomly divided into two groups: the exercise group and the control group. The 94 patients in control group were given conventional conservative treatment while the 95 patients in exercise group received “Weishi” functional exercise on the basis of conventional treatment. Results: Compared with the condition before the treatments, both the groups showed significant differences in VAS pain scores and Fair-bankJC scales after treatments. The effectiveness in exercise group was better. Conclusions: Along with the conventional treatment, the application of “Weishi” functional exercise would effectively alleviate the pain and improve the conditions.
