Quadriceps muscle strength test

The quadriceps muscle strength test is a method of examining the degree of spasm or spasm of the muscle. The main function of the quadriceps is to flex the thighs and straighten the calves. When the muscle group is paralyzed, the hip flexion is difficult and the quadriceps muscle is atrophied, which is a sign of paralysis of the femoral nerve (derived from the lumbar spinal cord 2 to 4). The patient is supine or sitting, the knee joint and the hip joint are pre-buckled, and then the calf is straightened. The examiner gives resistance to this movement and touches the contracted muscle at the thigh to measure the muscle strength. Basic Information Specialist classification: growth and development check classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The result of the test was negative. Normal muscle strength, no signs of paralysis. Positive: The test result is positive, that is, the muscle strength is abnormally weak, and it is a sign of paralysis of the femoral nerve (derived from the lumbar spinal cord 2 to 4). Tips: Check your relaxation, you should face it positively and actively cooperate with the inspection. Normal value The result of the test was negative. Normal muscle strength, no signs of paralysis. Clinical significance Abnormal results: The test result is positive, that is, the muscle strength is abnormally weak, and it is a sign of paralysis of the femoral nerve (derived from the lumbar spinal cord 2 to 4). The quadriceps are innervated by the femoral nerve (lumen 2 to 3), and the four heads are the rectus femoris, the medial femoral muscle, the lateral femoral muscle and the medial femoral muscle. The rectus femoris is located in the middle of the front, which is a fusiform plump muscle. It is a short sacral spine from the anterior superior iliac spine; the medial femoral muscle is located in the anterior medial aspect of the thigh, from the medial lip of the femoral condyle, and the muscle bundle is obliquely downward to the front; The muscle is located on the lateral side of the thigh, from the lateral lip of the femoral condyle; the medial femoral muscle is located deep in the rectus femoris, between the femoral and lateral muscles, from the front of the femur, with four heads attached downward to the upper edge of the tibia And the inner and outer margins, from the humerus to the lower ligaments to stop the humerus. The ligamentous ligament is thick and is the total sputum of the quadriceps. The muscle function is to stretch the calf, the rectus femoris and the flexor thigh. People who need to be examined: people who have weakness in their thighs. Positive results may be diseases: gluteal muscle contracture, stroke sequelae matters needing attention Taboo before inspection: no special contraindications. Requirements for inspection: Check the feelings of relaxation, should face positively, and actively cooperate with the inspection. Inspection process The patient is supine or sitting, the knee joint and the hip joint are pre-buckled, and then the calf is straightened. The examiner gives resistance to this movement and touches the contracted muscle at the thigh to measure the muscle strength. Not suitable for the crowd There are no taboos. Adverse reactions and risks Nothing.
