A study examined the effects of ice water [[caloric reflex test]] stimulation on [[H reflex]] amplitude in normal subjects and three [[complete spinal cord injury]] patients. H-reflexes were obtained by stimulating the [[tibial nerve]] at the popliteal fossa and recording the H-response from the [[gastrocnemius muscle]]
