摘要
目的:研究不同速度对躯干肌慢速等速肌力测试的影响,探讨用于躯干肌肌力评定的慢速等速肌力测试合理的速度参数。方法:健康受试者43例,使用美国产BiodexⅡAP型多关节等速测试系统测定躯干肌峰力矩(PT)、相对峰力矩(PT/BW)、总功(TW)、相对总功(TW/BW)和屈伸比值(F/E),测试角速度分别选用30°/s和60°/s。结果:伸展收缩测试时两组间的PT、PT/BW、TW和TW/BW比较差异有显著性意义(P<0.05),屈曲收缩测试时上述指标比较差异无显著性意义(P>0.05),两组间F/E差异有显著性意义(P<0.05)。结论:躯干肌慢速等速测试中,速度明显影响伸展测试值,30°/s比60°/s等速测试似更能反映躯干肌的力学特征,而对屈曲测试值的影响并不明显,在慢速范围内,屈肌肌力测试值似处于稳定的峰值状态。
Objective： To investigate the influence of velocity on low speed isokinetic concentric contraction testing of trunk muscle strength and find the best velocity.Method：43 volunteers were tested by Biodex Ⅱ^AP Mulit-joint System,testing velocity was 30°/s and 60°/s. Paired sample t test was used to analyse their peak torque （PT）,peak torque to body weight（PT/BW）,total work（TW）,total work to body weight（TW/BW） and flexion to extension（F/E） with SPSS11.0.Resuit： PT, PT/BW,TW,and TW/BW of extension had significant difference between the two groups （P〈 0.05）, but no significant difference between the two groups in their flexion testing（P〉0.05）,the F/E ratio was significant difference hetween the two groups （P〈0.05）.Conclusion：Velocity is the most important factor during low speed isokinetic concentric extension contraction testing of trunk muscle strength,but it has no influence on flexion testing, the F/E ratio is significant different in 30°/s and 60°/s testing.
