Abstract

During balancing on a seesaw normal individuals have a mean sway oscillation of 4.3 Hz, which is significantly lower (3.3 Hz) in patients with peroneal muscular atrophy. It is assumed that the oscillations in both cases are generated by spinal stretch reflexes and that the lower frequency in patients with peroneal muscular atrophy is due to their slower nerve conduction velocity. The balancing movements are altered when spinal stretch reflex activity is reduced by ischaemia but are normal in patients with a dorsal column lesion despite a similar sensory loss. The analysis of balancing movements can be a diagnostic tool in differentiating several sensory-motor disturbances.

摘要

在跷跷板上保持平衡时,正常个体的平均摆动频率为4.3赫兹,而腓骨肌萎缩症患者的平均摆动频率则显著较低(3.3赫兹)。据推测,这两种情况下的摆动均由脊髓牵张反射产生,而腓骨肌萎缩症患者频率较低是由于其神经传导速度较慢。当缺血导致脊髓牵张反射活动减弱时,平衡运动发生改变,但尽管感觉丧失情况相似,患有后索病变的患者的平衡运动却正常。平衡运动分析可作为鉴别多种感觉运动障碍的诊断工具。
