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

Effect of Tai Chi on the lumbar muscle strength in women with primary osteoporosis

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＆#176;/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＆#176;/s was higher, while the TPT and F/E of lumbar extension at 90＆#176;/s were lower than those in the vigorous walk group.The TPT of lumbar flexion at 90＆#176;/s in the vigorous walk group was lower than that in the Tai Chi group （P＆lt;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.
