  h reflex
Lower limb reflexes examined were: (1) the ratio of maximal H reflex to M response (H/M ratio), (2) the inhibition of the H reflex during vibration (Hvib/Hctl ratio), and (3) soleus stretch reflexes (SR/M ratio).
      
Deep tendon reflexes and H reflex were completely absent, but F waves were preserved.
      
The neurophysiological tests included motor and sensory nerve conduction velocity; F response, H reflex and electromyographic neuromuscular synapse testing.
      
However, peroneal motor conduction velocity (p>amp;lt;0.05) terminal motor latency of median (p>amp;lt;0.1), and peroneal nerve (p>amp;lt;0.05); F minimal latency and H reflex latency (p>amp;lt;0.01) were significantly affected.
      
Long-loop reflexes from arm afferents onto motoneurones of leg muscles were investigated in 57 healthy subjects by means of H reflex testing and tonic EMG testing.

The present research describes the different changes of H-reflex and M-responses in a slow muscle, soleus, and in a fast muscle, lateral gastrocnemius, of the man. Experimental results showed that the H-reflex had almost always the same threshold in the soleus and lateral gastrocnemius. When the intensity of the stimulus was increased,the H-reflex amplitude in soleus increased much more than in lateral gastrocnemius, The difference between the amplitudes of the H-reflex in slow and fast muscles was already evident...

The present research describes the different changes of H-reflex and M-responses in a slow muscle, soleus, and in a fast muscle, lateral gastrocnemius, of the man. Experimental results showed that the H-reflex had almost always the same threshold in the soleus and lateral gastrocnemius. When the intensity of the stimulus was increased,the H-reflex amplitude in soleus increased much more than in lateral gastrocnemius, The difference between the amplitudes of the H-reflex in slow and fast muscles was already evident with the stimuli subliminal for M-responses. There were no significant differences of the M-responses in both muscles when the intensity of the stimulus was increased. On the basis of these results showing a clear-cut difference in the reflex excitability of slow and fast muscles in man, we tend to conclude that type-1 alpha-motoneurones are exclusively depolarized by stimulation of afferent Ⅰ-a fibres. The type-1 alpha-motoneurones are exclusively or predominantly involved in the monosynaptic reflexes.

在正常人体刺激胫神经条件下观察诱发比目鱼肌(慢肌)和腓肠外侧肌(快肌)的H—反射和M—反应电活动的变化,分析慢肌和快肌直接反应和反射活动的差异,从而阐明脊髓何种类型α—运动神经元在单突触反射中起主要作用。实验结果表明,当M—反应在阈下刺激时比目鱼肌和腓肠外侧肌的H—反射阈值几乎相同。增加刺激强度但不出现M—反应时,比目鱼肌和腓肠外侧肌的H—反射振幅增加,但前者比后者大得多,有明显差异。当M—反应在阈上刺激时引起M—反应和H—反射,并随刺激强度增大二者振幅逐渐加大,但慢肌H—反射振幅比快肌大得多,而M—反应变化二者无明显差异。比目鱼肌属红肌,几乎完全由慢肌纤维组成,腓肠外侧肌属于白肌,主要由快肌纤维所组成.前者由Ⅰ—型α—运动神经元所支配,后者由Ⅱ—型α—运动神经元所支配.由此说明Ⅰ—型α—运动神经元是主要调节慢肌活动的,它由Ia传入纤维所去极化,而在单突触反射中起主要作用。

The role of carbohydrate metabolic abnormalities in the development of diabetic neuropathy is controversial. To investigate the influence of hyperglycemia on nerve conduction, 36 patients with NIDDM were studied. As a result, the motor nerve conduction velocities(MNCV) of median, ulna, and peroneal nerves were significantly slower while the distal sensory nerve incubation period (SNI) of median and ulna nerves as well as H-reflex latency time were longer than that of normal controls. Though fasting plasma glucose...

The role of carbohydrate metabolic abnormalities in the development of diabetic neuropathy is controversial. To investigate the influence of hyperglycemia on nerve conduction, 36 patients with NIDDM were studied. As a result, the motor nerve conduction velocities(MNCV) of median, ulna, and peroneal nerves were significantly slower while the distal sensory nerve incubation period (SNI) of median and ulna nerves as well as H-reflex latency time were longer than that of normal controls. Though fasting plasma glucose levels were correlated positively with HbA1 and H-reflex latency, they were negatively correlated with MNCV of the median, ulna, and peroneal nerves, and showed no correlation with SNI of the median and ulna nerves. Despite of their negative correlation with MNCV of the media, ulna, and peroneal nerves and positive correlation with SNI of the median and ulna nerves as well, HbA1 showed no correlation with H-reflex latnecy. These findings suggested that HbA1 might contribute to the development of peripheral neuropathy in diabetes mellitus rather than hyperglycemia, and that the association couldn't be ascribed to patient's age or duration of illness. In addition, SNI was found to be a sensitive index in the determination of sensory nerve function of diabetic neuropathy.

通过36例非胰岛素依赖型糖尿病(NIDDM)患者的神经传导速度与空腹血糖、HbA_1的关系研究,发现所有患者正中、尺、腓神经运动神经传导速度(MNCV)都显著减慢,正中、尺神经感觉神经潜伏期(SNI)延长,H反射时间延长,血糖与各条神经MNCV呈负相关,而与H反射时间呈正相关,但与各神经SNI无关。HbA_1与各神经MNCV呈负相关,与各神经SNI呈正相关。

本文对拟诊为腰骶神经根压迫症125例电生理测定和临床的关系作了统计分析。发现 H 反射与踝反射、肌电图与伸(?)肌力、肌电图 S_1神经与 H 反射和肌电图 S_1神经与踝反射的关系,均有统计学意义,P 值分别<0.001、0.05,0.05和0.01,但电生理测定与放射痛、直腿高举试验、间歇性跛行、脊柱过伸试验等均无明显关系。以上提示电生理测定反映粗纤维破坏性损害的临床表现,但不能反映细的无髓鞘 C 类纤维的刺激性临床表现。本文就神经根压迫损害对腰痛的意义作了探讨。
