Objective To explore the relationship between muscle strength and bone mineral density (BMD) in postmenopausal osteoporotic patients. Methods A total of 144 patients with osteoporosis, aging from 50 to 75 years old, were selected from October 2010 to January 2011 in Guangdong province. According to TCM syndrome differentiation, they were divided into kidney Yang failure group, liver and kidney Yin deficiency group, spleen and kidney Yang failure group, and Qi stagnancy and blood stasis group. Total muscle strength detection was performed in patients of 4 groups. The database was established using a SPSS 16.0 software. Results The maximal BMD of L1-4 was found in kidney Yang failure group, then in spleen and kidney Yang failure group, and the minimal strength was found in Qi stagnancy and blood stasis group. The maximal muscle strength was found in kidney Yang failure group, then in the spleen and kidney Yang failure group, and the minimal muscle strength was found in Qi stagnancy and blood stasis group. The comparison between kidney Yang failure group and spleen and kidney Yang failure group was not significantly different (P>0.05). The comparison between the other 3 groups and Qi stagnancy and blood stasis group was statistically significant (P<0.05). The waist back muscle strength was positively correlated with L1~4 average BMD. Conclusion BMD decreases from high to low in kidney Yang failure group, spleen and kidney Yang failure group, liver and kidney Yin deficiency group, and Qi stagnancy and blood stasis group, indicating that osteoporosis is more serious in Qi stagnancy and blood stasis group than in other 3 groups. Following the development of osteoporosis, the muscle strength also decreases, indicating that the waist muscle strength is positively correlated with BMD. |
