Combined Application of Electrical Stimulation and Volitional Contractions for Muscle Strengthening and Knee Pain Inhibition (Seated Study)

"Electrodes (Sekisui Plastics Co., Tokyo, Japan) will be placed on the anterior thigh over the motor points of the bilateral vastus medialis and lateralis, and on the posterior thigh over the motor points of the medial and lateral hamstrings. Electrical stimulation intensity will be set to approximately 40% of 1 repetition maximum (RM).~A joint motion sensor (Mutoh Engineering Inc., Tokyo, Japan) will trigger stimulation of the antagonist once it senses the initiation of volitional contraction of the agonist muscle group."

Low intensity exercises completed using isokinetic dynamometer (HUMAC NORM, Computer Sports Medicine Inc. (CSMi), Stoughton, MA) in isokinetic mode at approximately 40%1 RM.
