Abstract：Objective：To observe the clinical effect of functional exercise of Baduanjin in sitting for low back pain induced by osteoporosis(OP) in senile male patients. Methods：A total of 70 cases of senile male patients with low back pain induced by OP were divided into the treatment group and the control group according to the random number table method，35 cases in each group. After six-month treatment and follow- up ， some patients were excluded because of loss to follow-up ， bad compliance，and irregular practice of Baduanjin exercise. Finally，there were 43 cases enrolled in the study. The control group(25 cases) was given comprehensive treatments including optimization of lifestyle，as well as supplement of calcium， vitamin D， and anti- osteoporosis medicine； the treatment group(18 cases) was additionally given Baduanjin exercise in sitting based on the treatment of the control group. Before and after treatment，the scores of Visual Analogue Scale(VAS) for evaluating low back pain in each period were compared between the two groups. Before and after treatment， the score of modified Oswestry Dysfunction Index(ODI) for evaluating lumbar vertebral function and the level of bone mineral density(BMD) of L1~4 and femoral neck were compared between the two groups. Results：After one-month，two-month， three-month，and four-month treatment，there were no significant differences being found in the comparison of scores of VAS for evaluating low back pain between the two groups(P＞0.05). After five-month and six-month treatment，the scores of VAS in the treatment group were lower than those in the control group， the difference being significant(P＜0.05). After treatment，scores of modified ODI in the two groups were decreased when compared with those before treatment(P＜ 0.05)，and the decrease of the score in the treatment group was more significant than that in the control group(P＜0.05). After treatment，BMD of L1~4 and femoral neck in the two groups were increased when compared with those before treatment(P＜ 0.05)；there were no significant differences being found in the comparison of BMD of L1~4 and femoral neck between the two groups(P＞0.05). Conclusion：For senile male patients with low back pain induced by OP，regular Baduanjin exercise in sitting in a long run can effectively relieve symptoms of the lower back pain.
