ABSTRACT

Introduction: H-reflex is a technique to evaluate nerve conduction through afferent and efferent pathways, especially in proximal peripheral nerve segments, as well as neurophysiological changes in involved nerve roots. Abnormalities in the H-reflex correlates with root pathology reflected on prolonged latency or its absence on the affected side. Linear regression analyses have been conducted to estimate the expected latency of the H-reflex based on current literature. Objective: we aimed to design a normogram and equation to predict median nerve H-reflex latency based on upper extremity length and arm length in a group of healthy subjects. Material and methods: an observational, prospective analysis was carried out including healthy subjects submitted to nerve conduction studies. Results: simple linear regression model showed a predictive value of 15.1% for arm length compared to upper extremity length with a 12.6% predictive value (p < 0.000). Conclusions: H-reflex equation to predict H-reflex latency based on arm length was determined as: latency H = 4.865 + 0.225 (arm length).
