Objectives: This study is aimed to look into what effect mirror therapy has on the muscle activity of a hand when it is applied to healthy individuals. Methods/Statistical Analysis: The participants of the experiment were 22 healthy adults without musculoskeletal disease at upper extremity. For the mirror therapy, a mirror is placed on the center of a table in front of a subject. To check the changing muscle activation between pre-test and post-test the mirror therapy, this study was usedsEMG about MP 36 USA Biopac System. Findings: As a first result about comparison of resting and left movement, the muscle activity was shown to have increased in a thenar muscle, a hypothenar muscle, a flexor bundle muscle, an extensor bundle muscle with a significant statistical difference. As a second result about comparison of right movement and both movement, the muscle activity did not show a significant statistical difference in the thenar muscle, hypothenar muscle, flexor bundle muscle, extensor bundle muscle. Improvements/Applications: Mirror therapy will benefit the muscle activities of patients whose limbs are paralyzed through the brain activation even though there isn’t any movement in the limbs in the future.
