Brachioradialis muscle strength test

The diaphragmatic muscle strength test is a method to check whether the muscle has sputum or spasm. The main function of the diaphragm is to bend the elbow and turn the forearm from the supination position to the pronation position. When the tendon is in, the forearm can not be rotated, the hand is generally pronated, and passively in the posture of the upper limb sagging. After the spin, it still turns to the pronator position. Basic Information Specialist classification: neurological examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Do not be too nervous during the examination to prevent excessive muscle tension and affect the results of the examination. Normal value The forearm is free to rotate from the supination position to the pronation position. Clinical significance Abnormal results: The main function of the diaphragm is to bend the elbow and turn the forearm from the supinator position to the pronator position. When the tendon is used, the forearm can not be rotated, and the hand is generally pronated, in the posture of the upper limb sagging. After passively rotating it, it still turns to the pronator position, which is a sign of paralysis of the phrenic nerve (derived from the cervical spinal cord 5-7 and the posterior bundle of the brachial plexus). People who need to be examined: patients with diaphragmatic spasms. Precautions Pre-examination taboo: Maintain a normal diet and schedule, without worrying too much. Requirements for inspection: Do not be too nervous during the examination to prevent excessive muscle tension and affect the results of the examination. Inspection process During the examination, the patient's forearm was rotated before and after the supine neutral position, and then the elbow was flexed. The examiner gave an impedance to the movement and touched the muscle contracted by the patient's forearm. Not suitable for the crowd A patient with an injured or disabled arm. Adverse reactions and risks Generally no adverse reactions.
