Reflex testing h wave

WebHow is H-reflex test done? The procedure to elicit the H-reflex usually involves applying a percutaneous electric stimulus to a mixed nerve. For example, when eliciting the soleus H-reflex, a 1-millisecond square wave pulse is applied to the posterior tibial nerve in the popliteal fossa. What is H wave reflex? WebH reflexes are a sensitive test for polyneuropathies and may be abnormal even in mild neuropathies. H reflexes involve conduction in proximal as well as distal fibers. These …
