Abrams, Howard J. Waldman, in Practical Management of Pain (Fifth Edition), 2014 Pitfalls and Comments. The H-reflex is somewhat more useful than the F wave, but the main reason for the study is to evaluate patients with suspected S1 radiculopathy whose history or findings on physical examination are suggestive but the EMG is normal. 34 …
Web29 aug. 2024 · H reflexes and F waves are commonly recorded electrophysiologic responses ( Figs. 18-1 , 18-2 , and 18-3 ). H reflexes are reflexes that are produced by afferent conduction in large afferent fibers and by efferent conduction in alpha motor neurons. By contrast, F waves are produced by antidromic activation (“backfiring”) of the …
