IOcurves and IOcurve slopes in the APB. The mean MEP amplitude (in mV± SE) as given on the y-axis against the stimulus intensity given on the x-axis (in percentage of SI1mV). A, B, IOcurves measured at baseline and after immobilization in the PAS25 group (A) and the PAS10 group (B). In both groups, the IOcurves are less steep after immobilization compared with baseline. C, The slopes of the IOcurves have been calculated for the approximately linear part between 90 and 130% SI1mV. The decrease of IOcurve slopes after immobilization is significant in both groups (paired t test; p < 0.001).
