supinator muscle strength test

The supinator muscle strength test is a method to check whether the muscle has sputum or spasm. The main function of the supinator muscle is to make the forearm supin. In this tendon, the lateral extension of the wrist and the wrist abduction are not possible, which is manifested as the wrist drooping and the wrist adduction. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The forearm can do free spin-back movement. Positive: The main function of the supinator muscle is to make the forearm supin. In this tendon, the lateral extension of the wrist and the wrist abduction are not possible, manifested as the wrist drooping and the wrist adduction, which is a sign of paralysis of the phrenic nerve (derived from the cervical spinal cord 5-8 and the posterior bundle of the brachial plexus). Tips: Maintain a normal diet and schedule. Normal value The forearm can do free spin-back movement. Clinical significance Abnormal results: The main function of the supinator muscle is to make the forearm supin. In this tendon, the lateral extension of the wrist and the wrist abduction are not possible, manifested as the wrist drooping and the wrist adduction, which is a sign of paralysis of the phrenic nerve (derived from the cervical spinal cord 5-8 and the posterior bundle of the brachial plexus). People who need to be examined: patients with supination tendon. Positive results may be diseases: radial nerve palsy, brachial plexus injury, paralytic brachial plexus neuritis, sacral nerve injury precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for inspection: Actively cooperate with the doctor's work, do not overstretch when the forearm can not be rotated. Inspection process During the examination, the patient stretches the forearm and then spins from the pronator position, and the examiner gives an impedance to the action to detect the muscle strength. Not suitable for the crowd Unsuitable for the crowd: patients with damaged or disabled arms. Adverse reactions and risks Nothing.
