Abstract: Objective: To evaluate if there is a relationship between somatosensory evoked potential (SSEP) of tibial nerve of people with paraplegia and classification of ASIA (American Spinal Injury Association) and to assess the difference intra- and inter- group in the latency's values of the tibial SSEP. Methods: Ten individuals with paraplegia (Group 1), one year of lesion at least, 3 ASIA C, 2 ASIA B and 5 ASIA A and 8 healthy individuals (Group 2) were evaluated. Electrophysiological assessment of the median nerve was performed by evoked potential equipment and the injury level was obtained by ASIA. The N8, N22 and N45 latencies were analyzed based on the presence or absence of such variables and observed whether SSEP recordings were normal or delayed using the mixed linear models. Results: In all individuals the N8 and N22 were found. In paraplegics ASIA A and B the cortical latency was absent; in paraplegics ASIA C the cortical latency was present, but with difference between the latencies of healthy and paraplegic people (p<0.05). The differences between the sides, right and left, in the group 1 (p<0.05) were also verified by ASIA. Conclusion: These results suggest that there is a relation between the ASIA and SSEP evaluations, since the SSEP exam confirmed the clinical evaluation done by ASIA. This relation is important due to thefact that the SSEP evaluation is not always available and, on the other hand, the ASIA assessment is simple, cheap and easy to apply.
