Table 3: SCM VEMPs (ipsilateral to monaural acoustic stimulation), and SETMPs (contralateral to monaural acoustic stimulation). The SCM VEMP is the mean (±SD) of the right and left response ipsilateral to the acoustic stimulus. The SETMP responses are the mean (±SD) of the right and left response contralateral to the ear that received the acoustic stimulus for the spinal cord lesion or control subjects. Since 9 out of 14 spinal cord lesion subjects did not have a SETMP response, the latencies for spinal cord lesion subjects are the mean (±SD) of those with a response, however, the inter-amplitudes are the mean (±SD) of all spinal cord lesion subjects.
