H-reflex data

The Hoffmann reflex (H-reflex) is an electrically induced reflex that bypasses the muscle spindle. H-reflex is a useful measure to assess modulation of monosynaptic reflex activity in the spinal cord.
H-reflex studies can be set up multiple ways and users should determine the best approach for their required protocol; BIOPAC cannot recommend a “standard” approach for H-reflex.
