Abstract：
Introduction The Hoffmann reflex (H reflex) is one of the most studied reflexes in human neurophysiological literature. Detection of the H reflex is useful in the diagnosis of early polyneuropathy, S1 radiculopathy, early GBS, tibial neuropathy and sciatica, and sacral plexopathy. The H reflex is also used as a tool to measure the excitability of the nervous components of the arc, regardless of the sensitivity of the sensory organs. The monosynaptic nature of reflex circuits makes H-reflex an attractive tool for clinical neurophysiology and research. Objective The objective is to create reference data of soleus H-reflex latency in an adult population from a tertiary care center in India. Materials and methods Seven hundred eighty-four healthy volunteers underwent a physical examination and brief electrophysiological examination before elicitation of the soleus H reflex of both lower extremities using standard techniques. Reference values are expressed as mean ± standard deviation as well as the third and 97th percentiles for latency as the dependent variable. Results The study population included 346 (44.1%) women and 438 (55.9%) men. The men were aged 40.46 ± 14.76 years, and the women were aged 41.63 ± 13.49 years. The average weight of the men was 73.32 ± 10.28 kilograms, and the women were 62.91 ± 7.46 kilograms. The average height of the men was 172.06 ± 4.22 cm, and the women were 159.12 ± 2.42 cm. The third and 97th percentiles for H-reflex latency on the right side were 22.86 ms to 34.22 ms and on the left side were 22.86 ms to 35.39 ms. The average right tibial H latency and left tibial H latency were 28.18 ± 2.59 ms and 28.14 ± 2.70 ms, respectively. Conclusion A sizable subject population was used to provide reference data for this study. Because of the huge sample size and nearly appropriate coverage of different age groups, reference ranges have been established for various age, height, and BMI groups.
摘要：
引言霍夫曼反射(H反射)是人类神经生理学文献中研究最多的反射之一。检测H反射有助于诊断早期多发性神经病,S1神经根病，早期GBS,胫骨神经病和坐骨神经痛,和骶丛神经病变.H反射也被用作测量弧形神经成分兴奋性的工具，不管感觉器官的敏感性。反射回路的单突触性质使H反射成为临床神经生理学和研究的有吸引力的工具。目的目的是从印度的三级护理中心创建成人比目鱼H反射潜伏期的参考数据。材料与方法在使用标准技术诱发下肢比目鱼H反射之前，对74名健康志愿者进行了体格检查和简短的电生理检查。参考值表示为平均值±标准偏差，以及延迟的第三和第97百分位数作为因变量。结果研究人群包括346名(44.1%)女性和438名(55.9%)男性。男子年龄为40.46±14.76岁,妇女年龄为41.63±13.49岁。男子平均体重为73.32±10.28公斤,女性为62.91±7.46公斤。男性平均身高为172.06±4.22厘米,女性为159.12±2.42cm。右侧H反射潜伏期的第三百分位数和第97百分位数分别为22.86ms至34.22ms，左侧为22.86ms至35.39ms。平均右侧胫骨H潜伏期和左侧胫骨H潜伏期分别为28.18±2.59ms和28.14±2.70ms,分别。结论本研究采用了相当大的研究对象人群,为研究提供了参考数据。由于样本量巨大，不同年龄段的覆盖范围几乎合适，已经为不同年龄建立了参考范围，高度,BMI组。
