Abstract:
Study was conducted in laboratory condition for investagating the relationship between muscle strain and arm positions. Rerults showed that: the bio-potential of brachioradialis, deltoid and trapezius muscles were significant higher when the arms were elevated at haft-arm length. The trapezius had highest bio-potential than the other left. The subjective shoulder pain occurred after 15-17 mimutes of experiment. When was higher hio-potential, that the muscle pain was more obvious. The accumulation of pain can be considered as reason of that called Neck-Shoulder Disorders.
