WebPrime mover: also known as the agonist, is the muscle primarily responsible for producing a specific movement. For example, the biceps brachii muscle is the prime mover during elbow flexion, as it contracts to bend the elbow joint. Antagonist: is the muscle that opposes, or reverses, the action of the agonist muscle. WebHowever, a person’s shoulder mobility may prevent a full range of motion and in this case using the 90° rule (upper arms parallel to the floor, 90° of elbow flexion) may be a safer …
