摘要:
      摘要 目的:对比青年慢性非特异性腰痛(CNLBP)患者和正常健康青年腰部本体感觉及肌力的差异,并分析腰部本体感觉与肌力的相关性。 方法:选取25例青年CNLBP患者纳入腰痛组,25例正常健康青年纳入对照组。采用CON-TREX等速系统测试其腰部本体感觉及腰部屈肌、伸肌肌群在60°/s角速度下的等速向心肌力。以被动复位绝对误差角度(AE)作为个体本体感觉评价指标,以各肌群的峰值力矩(PT)、峰力矩体重比(PT/BW)及屈/伸肌峰值力矩比(F/E)作为等速向心肌力观察的主要指标。并分析CNLBP患者腰部本体感觉与腰部肌力的相关性。 结果:①腰痛组患者腰部前屈、后伸的AE值均高于对照组,差异有显著性意义(P<0.05);②腰痛组患者伸肌肌群的PT及PT/BW与对照组相比均有降低,差异有显著性意义(P<0.05);腰痛组患者屈肌肌群的PT及PT/BW与对照组相比,差异无显著性意义(P>0.05);同时腰痛组F/E与对照组相比,差异无显著性意义(P>0.05);③腰痛组腰部AE值与PT、PT/BW及F/E之间均无相关性(P>0.05)。 结论:青年CNLBP患者的腰部本体感觉及腰部伸肌肌群肌力均较正常健康青年有所减弱,且青年CNLBP患者的腰部本体感觉与腰部肌力之间无相关性。

Abstract:
      Abstract Objective: To compare the differences of lumbar proprioception and muscle strength between the young patients with chronic nonspecific low back pain (CNLBP) and healthy young people, and3 the correlation between lumbar proprioception and muscle strength. Method: Twenty-five patients with CNLBP (CNLBP group) and 25 healthy young people (control group) were included. Lumbar proprioception and strengths of lumbar flexor and extensor at the speed of 60°/s were measured by using the CON-TREX isokinetic test system. Lumbar proprioception was evaluated by the absolute error (AE) in passive replication test. The peak torque (PT), peak torque to body weight ratio (PT/BW) and the ratio of peak torque of flexor and extensor (F/E) were observed as the main index of isokinetic strength. Also we analysed the correlation between lumbar proprioception and muscle strength in CNLBP group. Result: ① The AE of lumbar flexion and extension of CNLBP group were both higher than control group (P<0.05). ② The PT and PT /BW of lumbar extensors of CNLBP group were less than control group (P<0.05). However, there is no statistical differences between the two groups on PT and PT/BW of lumbar flexor, and the ratio of F/E (P>0.05). ③ There is no significant correlation between the AE and the isokinetic strength in CNLBP group (P>0.05). Conclusion: Compared with the healthy young people, both the lumbar proprioception and the strengths of lumbar extensor of young patients with CNLBP were decreased. And we did not find correlation between the lumbar proprioception and muscle strength in young patients with CNLBP.
