摘要
目的观察不同角速度等速肌力训练对腰痛患者的腰背部核心肌群的训练效果,探讨改善慢性腰痛的更优角速度。方法 2016年1月至2018年6月,本院男性慢性腰痛患者60例,随机分为A、B、C三组,每组20例。A组行常规康复治疗手段;B组、C组分别在常规康复治疗基础上,选取角速度为30°/s和90°/s的等速肌力训练,每周3次,共训练4周。训练前后进行等速肌力测试,记录峰力矩和平均功率。结果训练后,B组和C组屈、伸肌峰力矩及功率均大于A组(P <0.05),C组屈、伸肌峰力矩小于B组(P <0.05),屈、伸肌功率与B组无显著性差异(P> 0.05)。训练后,B组、C组VAS评分均明显降低(t> 4.098,P <0.01),且均低于A组(P <0.05),C组和B组间无显著性差异(P> 0.05)。结论等速肌力训练可提高腰痛患者的躯干屈、伸肌群的峰力矩和功率,低角速度(30°/s)等速训练效果更佳。
Objective To explore the effect of isokinetic muscle strength training at different angular velocities on the core muscles of patients with low back pain,and to find out the better angular velocity.Methods From January,2016 to June,2018,60 patients with chronic low back pain were randomly divided into three groups,with 20 cases in each group.Group A(control group)only received routine rehabilitation therapy.Additionally,groups B and C received isokinetic muscle strength training at 30°/s and 90°/s,respectively,three times a week for four weeks.They were measured peak torque and average power before and after training.Results After training,the peak torques and powers of both flexor and extensor were higher in groups B and C than in group A(P<0.05),the peak torques of both flexor and extensor were lower in group C than in group B(P<0.05),however,no significant difference was found in powers of both flexor and extensor between groups B and C(P>0.05).After training,the score of VAS decreased in groups B and C(t>4.098,P<0.01),and was lower in groups B and C than in group A(P<0.05),however,no significant difference was found between groups B and C(P>0.05).Conclusion Isokinetic muscle strength training could increase the peak torque and power of trunk flexor and extensor in patients with low back pain,in which lower angular velocity(30°/s)has a better effect.
