In 80 controls latencies of flexor carpi radialis (FCR) and in 94 controls latencies of soleus H-reflexes correlated well with length of the extremity, body height and age. Multiple regression equations using latency as a variable dependent on age and body height can be best used in practice when both reflexes are employed for demonstration of proximal pathology. The majority (69%) of 93 patients with various polyneuropathies showed abnormalities in both reflexes illustrating that proximal nerve segments are frequently involved. Four per cent had abnormal FCR H-reflexes with normal soleus H-reflexes whereas the reverse was found in 19% of the patients. Abnormal FCR H-reflexes occurred with normal motor and sensory conduction velocities in the peripheral part of the median nerve in 14%, whereas the reverse was seen in 12%, indicating that FCR H-reflex examination is a valuable supplement to conventional conduction studies for detection of electrophysiologically existing pathology.
在80名对照者中，桡侧腕屈肌（FCR）潜伏期与94名对照者比目鱼肌H反射潜伏期均与肢体长度、身高和年龄密切相关。当同时使用这两种反射来证明近端病变时，在实践中最好使用以潜伏期作为年龄和身高相关变量的多元回归方程。93例患有各种多发性神经病的患者中，大多数（69%）的两种反射均显示异常，这说明近端神经节段经常受累。4%的患者FCR H反射异常而比目鱼肌H反射正常，而19%的患者情况相反。14%的患者FCR H反射异常，而正中神经外周部分的运动和感觉传导速度正常，反之12%的患者则相反，这表明FCR H反射检查是传统传导研究检测电生理存在病变的有价值补充。
