total finger extensor muscle strength test

Refers to the total extensor muscle strength test is a method to check whether the muscle has sputum and sputum. The main function of the total extensor muscle is to make the first knuckle of the second to fifth fingers straight and have a wrist extension. In this tendon, the first knuckle is significantly flexed and the little finger flexion is more pronounced, the fourth finger is slightly flexed, and the third finger is lighter, and the mid-finger and the end energy-saving portion are straightened due to the action of the interosseous muscle. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: You can relax your finger joints before checking so that the check goes smoothly. Normal value The first finger of the second to fifth refers to energy saving and straightening. Clinical significance Abnormal result The main function of the total extensor muscle is to make the first knuckle of the second to fifth fingers straight and have a wrist extension. In this tendon, the first knuckle is significantly flexed and the little finger flexion is more pronounced, the fourth finger is slightly flexed, and the third finger is lighter, and the mid-finger and the end energy-saving portion are straightened due to the action of the interosseous muscle. The tendon is a sign of paralysis of the phrenic nerve (derived from the cervical spinal cord 7-8 and the brachial plexus and the posterior bundle). People who need to be checked Refers to patients with total extensor tendon. Precautions Contraindications before examination: You can relax your finger joints before examination so that the examination can proceed smoothly. Requirements for inspection: Do not overstretch when your fingers cannot flex. Inspection process When the patient's finger is flexed during the mid-section and the distal end, the first knuckle of the second to fifth fingers is straightened, and the examiner gives the impedance to measure the muscle strength. Not suitable for the crowd A patient with a damaged or disabled hand. Adverse reactions and risks Generally no adverse reactions.
