tendency towards significancep = 0.057
The presence of central fatigue was detected; FSS score was significantly correlated to maximal voluntary contraction (MVC baseline and 60%, r-baseline = -0.583, p < 0.01, r-60% = -0.534, p < 0.05), and to motor disability measured by MRC (r = -0.496, p < 0.05); moreover we found a strong tendency towards significance in the association with lactate baseline (r = 0.378, p = 0.057).
