In 50 patients with lumbar nucleus pulposus prolapse the force of femoral abductors was determined by the test of Lovett and by means of dynamometric measurements. In 90% of patients paresis of these muscles was found. A comparison of the incidence of other signs of nerve root damage such as paresis of plantar and dorsal flexion of the foot and toes, sensory impairment on the foot and lack or weakness of ankle jerk showed that paresis of fermoral abductors was most frequent among them. This fact is explained by a particular predisposition for development of uncleus pulposus prolapse at the level of 4th and 5th intervertebral discs with resulting injury to the nerve roots L4, L5, and S1 innervating femoral abductors. The authors think that paresis of femoral abductors may be a pathognomonic sign in the diagnosis of nerve root lesions caused by nucleus prolapse at the levels L4-L5 or L5-S1. The frequency of paresis and the degree of weakness indicate the necessity of motor rehabilitation of this music group in comprehensive treatment of patients with lumbar disc prolapse.
对50例腰椎间盘突出症患者，通过Lovett试验及测力测量法测定了股外展肌的肌力。结果发现，90%的患者存在这些肌肉的麻痹。对其他神经根损伤体征的发生率进行比较，如足趾背屈和跖屈麻痹、足部感觉障碍以及踝反射减弱或消失，结果显示股外展肌麻痹在这些体征中最为常见。这一事实可解释为，第4和第5椎间盘水平特别容易发生椎间盘突出，从而导致支配股外展肌的L4、L5和S1神经根受损。作者认为，股外展肌麻痹可能是L4 - L5或L5 - S1水平椎间盘突出所致神经根病变诊断中的一个特征性体征。麻痹的发生率及无力程度表明，在腰椎间盘突出症患者的综合治疗中，对该肌群进行运动康复很有必要。
