Correlation of the Somatosensory Evoked Cerebral Potentials of Median Nerve Between Healthy and Respondents with Multiple Sclerosis
Amplitude of wave P22 for 14% of respondents with MS was 0.1-1 µV, the number of patients with the amplitude 1-5µV in the experimental group was lower by 12% and by 3% smaller number of patients with the amplitude 5-10 µV compared to the control group. Shown results indicated statistically significant difference of decreased values for the P22 wave in experimental compared to the control group. ( X2=109,896 p<0.01). CONCLUSION: In our research values of the cortical waves N19 and P22 amplitudes was significantly decreased among patients with MS compared to healthy respondents. This parameter of measuring evoked response besides prolonged latency can be considered significant as proof of pathological waves in SSEP among patients with multiple sclerosis especially during the acute phase of illness.
