Focal joint cooling has been shown to increase the Hoffmann reflex (H-reflex), an index of spinal excitability, in the lower extremity. Unfortunately, the H-reflex is influenced by many segmental physiological factors making it difficult to delineate the mechanistic underpinnings of this previously observed phenomenon. Accordingly, this thesis sought to determine if cryotherapy alters motoneuron excitability by using an innovative technique that permits a more direct assessment of A-motoneuron excitability. To approach this aim, we investigated the effects of focal wrist joint cooling on the flexor carpi radialis muscle’s H-reflex response as well as cervicomedullary evoked potentials (CMEPs) in 10 healthy male participants. A 2 x 2 repeated measures ANOVA was used to compare the H-reflex and CMEP measurements following a cryotherapy or sham intervention. No time by treatment interactions were observed for any outcome variables. In summary, focal joint cooling does not alter H-reflex or CMEP amplitude measurements immediately posttreatment.
