[전극]#32_Electrode Placement for Knee Flexion

The greater trochantor and the popliteal fossa are marked. Large electrodes are used to activate this diverse muscle group, with a symmetric biphasic waveform. The proximal electrode is placed medially to activate all of the hamstrings near their origin. The distal electrode is placed about midline. During stimulation you must remember the biomechanics of the hamstring muscles require fifteen degrees of knee flexion to allow further knee flexion. The stimulated contraction is three minus out of five in this position. Stronger contractions result in muscle cramping. For treatment purposes stimulation is better carried out in a short sitting position with resistance against the hamstring
