Article Title: Monopolar surface electromyography: a better tool to assess motoneuron excitability upon passive muscle stretching

doi: 10.1007/s12576-009-0027-9

Figure Lengend Snippet: Arrangement of surface electromyography (sEMG) electrodes. The G1 electrode position is 2 cm distal to the insertion of the medial gastrocnemius muscle (MG) into the Achilles tendon and is used for both sEMG methods (bipolar and monopolar). In the bipolar sEMG, the G2 electrode (BG2) is placed 3 cm distal to G1. In the monopolar sEMG, the G2 electrode (MG2) is placed 3 cm medially and 2 cm superiorly to medial malleolus (MM) and over the Achilles tendon. The reference electrode (R) of both methods is placed anterior over the tibial bone at a distance between the stimulus site and G1 electrode (dashed circle).The stimulating site (S) is approximately 1 cm lateral to the popliteal crease mid-point (PCM)

Article Snippet: The arrangement of the electrodes is illustrated in Fig. , and a circular disposable self-adhesive sEMG electrode with a diameter of 20 mm (VIASYS healthcare, Neurocare group, Conshohocken, PA) was used.

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 = 0.011
