The number of occurrences of a significant electromyographic (EMG) stretch response (“Responses” flexor) in a given muscle is expressed as percentage of the total number of trials. “Subjects” indicates the number of subjects in whom at least one response occurred. FDS, flexor digitorum superficialis; EDC, extensor digitorum communis; FCU, flexor carpi ulnaris; B, brachioradialis; BB, biceps brachii; TB, triceps brachi; PM, pectoralis major; LD, latissimus dorsi; DM, deltoideus medius.
