摘要
目的观察腰椎间盘突出症患者在Slump试验前后下肢的等速肌力变化。方法对10例腰椎间盘突出症患者进行Slump试验,即患者在屈颈、屈胸状态下进行伸膝动作。采用CybexNorm型等速练习器,记录Slump试验前后,双下肢峰力矩、力矩加速时间、耐力比等指标,并记录伸膝角度。结果在Slump试验时,健侧伸膝角度为(7±8)°,患侧为(18±22)°,健侧伸膝角度减少(5±7)°,患侧伸膝角度减少(9±8)°,两者相比,患侧在Slump试验前后伸膝角度差值显著减小(t=2.37,P<0.05)。结论Slump试验可协助腰椎间盘突出症的诊断,其机制可能与Slump试验时患侧股四头肌肌力下降、影响患侧伸膝角度有关。
Aim To observe the muscle strength of low er limbs in pa-tients with lumbar int ervertevral disc herniation by the isokinetic system be-fore and after Slump te st.Methods Ten patients with lumbar interverte bral disc herniation,5males a nd 5female s with the average age of(40±14)years,including 2cases of L 3-4 ,5cases of L 4-5 ,and 3cases of L 5 -S 1 ,were studied by Cybex-Norm before an d after Slump test.The parameters i ncluded peak torque,acceleration time and endurance ratio of quadriceps and ham string,and ROM of knee joint.Results Slump test,the ROM of ill leg was(18 ±22)°,with reduced by(9±3)°,significantly higher than that of the n ormal leg(9±8)°,which reduced by(5±7)°.The results showed that ROM of the involved legs decreased significantly after Slump test(t=0.37,P< 0.05).Conclusion Slump test is useful in diagnosis of l umbar intervertebr al disc herniation,whose mechanism is probably correlate d with the decreased m uscle strength and RO M.
