Secondary

MeasureTime frame
1. Group differences in MAS of elbow flexor muscles after 1 month of intervention 2. Group differences in effect of MAS for wrist flexors and finger flexors immediately after intervention and after 1 month 3. Group differences in AOC, ROM of elbow extension and wrist dorsiflexion, ROM of hand extension, and tendon reflexes of elbow flexors and wrist flexors immediately after the intervention and 1 month after the intervention. 4.
