To investigate the effects of Duhuo Jisheng Decoction combined with friction step training on bone density and muscle strength of lower limbs of the elderly patients with osteoporosis. Methods:Ninety-six elderly patients with osteoporosis who were admitted and treated in the First Hospital of Shijiazhuang from April 2013 to December 2015 were selected and randomly divided into control group (n=48) and study group (n=48). The patients of control group were treated with Caltrate with ossification calcitriol treatment, and patients of study group were treated with Duhuo Jisheng Decoction combined with friction step training for 8 weeks. The clinical pain relief and bone mineral density were measured, and the lower limb muscle strength was assessed. The serum bone metabolic markers, clinical efficacy and safety were compared after the treatment. Results:Compared with the state before treatment, scores of resting pain, back pain, over flexion and extension pain decreased, and scores of bone mineral density of lumbar spine L2-4 and right femoral neck increased. Slow extensor muscle strength increased, and flexor muscle flexor muscle, extensor muscle strength and speed increased. Contents of Ca and P increased, and AKP decreased (P<0.05); Compared with the control group, scores of resting pain, back pain, over flexion and extension pain were lower, and scores of bone mineral density of lumbar spine L2-4 and right femoral neck were higher. And slow extensor muscle strength were higher, and flexor muscle flexor muscle, extensor muscle strength and speed were higher. and content of Ca and P were higher, and AKP were lower(P<0.05); The effective rate of the patients in the control group was 75.00%, which was lower than that of study group 91.76% (P<0.05). Conclusion:Duhuo Jisheng Decoction combined with friction step training has significant therapeutic effect on senile osteoporosis, and significantly improve bone density and muscle strength of lower limbs, and improve bone metabolism and clinical symptoms, which was worthy of wide promotion.
