25 patients with stroke and hemiparesis in antecedents were recruited for the study. Objective: Recording Short Latency Somato-Sensory Evoked Potentials (SSEP) in dynamics and clinical assessment of th motor impairments. Results: The latency of the N20 wave from SSEP calculated from the dynamic recordings is increased at the level of the injured hemisphere. Medium latency of the recorded N20 wave at the level of the injured hemisphere and the recording at the level of the uninjured hemisphere have a statistically significant difference (p<0.05). Conclusion: The absence or minimal modification of the SSEP post-stroke is correlated with an improved motor performance, while increased latencies of the N 20 wave are associated with a low rate of motor rehabilitation after the stroke(in this case, SSEP modifications can appear for long periods).
