Case 14 Reflex Thresholds

For each set of reflexes, complete the tables at the bottom of the page by adding the reflex thresholds, then calculating the sensation level and determining if the reflex threshold (dB HL) is higher than one would expect given the degree of hearing loss.

Right Ipsilateral Reflex Traces
