Fig. 2From: Monopolar surface electromyography: a better tool to assess motoneuron excitability upon passive muscle stretchingAbsolute maximal H-wave (Hmax) and maximal M-wave (Mmax) values. Mean ± standard error (SE, n = 12) of the bipolar sEMG (a) and ordinary monopolar sEMG (b) at a resting (R) condition and passive stretching (PS) speed of 2, 5 and 10° s−1 (R, PS2, PS5, and PS10, respectively). *P < 0.001, **P = 0.011Back to article page
