Abstract INTRODUCTION: The Hoffmann reflex or H reflex is an electrical counterpart of the myotatic reflex. In normal adults is elicited with stimulating the tibial and the median nerves. It is useful as an adjunct study of neuroexamination and assesses the corresponding arc reflexes in their integrity. SUBJECTS AND METHODS: 248 H reflexes were studied stimulating the tibial nerve in 124 healthy subjects. RESULTS: The latency values were: minimum 23.6 ms; maximum 29.8 ms; mean value 27.6 ± 1.41 ms. CONCLUSION: This work explains the technique to obtain the H reflex and discusses the need for normalized values for each neurophysiology lab.
