太极拳运动对女性原发性骨质疏松症患者腰背肌力的影响

摘要

目的：探讨太极拳运动对原发性骨质疏松症（ POP）患者腰背肌力的影响，为进一步对POP的综合康复方案进行优化奠定基础。方法30例原发性骨质疏松症患者（太极拳组）进行每次1 h，每日1次，每周6次，周期为6个月的“陈式太极拳运动”训练，另外30例原发性骨质疏松症患者（健步走组）进行每次1 h，每日1次，每周6次，周期为6个月的普通健步走运动，对两组患者进行训练前后的腰屈伸等速肌力测试，对腰屈伸的AROM、PT、PT/BW、TW、TPT及F/E等数值进行分析。结果太极拳组干预后的AROM、60°角速度时腰屈曲及腰伸展的PT、PT/BW均明显高于健步走组，90°角速度时腰伸展的TW高于健步走组、TPT及F/E低于健步走组；而健步走组在90°角速度时腰屈曲的TPT略低于太极拳组（ P＜0.05）；结论与健步走运动相比，使用太极拳对原发性骨质疏松症患者进行运动训练，可以使患者的腰背屈伸肌力得到更明显的提高。%Objective To investigate the effect of Tai Chi on the lumbar muscle strength in postmenopausal women with primary osteoporosis ( POP) , in order to lay the foundation for optimizing comprehensive rehabilitation training programs of POP.Methods Thirty patients with POP in Tai Chi group practiced Chen’ s Tai Chi for 1 hour per day, 6 times per week, lasting for 6 months. And the other 30 patients with POP in vigorous walk group took a common vigorous walk for 1 hour per day, also 6 times per week and lasting for 6 months.The lumbar muscle strength in both groups before and after the practice was measured.The results of active range of motion (AROM), peak torque (PT), peak torque to body weigh t(PT/BW), total work (TW), time to peak torque (TPT), and flexion to extension (F/E) were analyzed.Results After the intervention, AROM, PT, PT/BW at 60°/s (60 angular velocities) at both lumber flexion and extension state in the Tai Chi group were significantly higher than those in the vigorous walk group.TW of lumbar extension at 90°/s was higher, while the TPT and F/E of lumbar extension at 90°/s were lower than those in the vigorous walk group.The TPT of lumbar flexion at 90°/s in the vigorous walk group was lower than that in the Tai Chi group (P<0.05).Conclusion Comparing with the vigorous walk, the application of Tai Chi in the practice for patients with POP can obtain more obvious improvement of the lumbar muscle strength.
