muscle tone check

The muscle tone test is a method of checking the tension of the muscles in a state of static relaxation. When the patient's muscles are slack, the doctor's hands hold the patient's limbs, with repeated speeds and rotations at different speeds and amplitudes. The slight resistance felt is the muscle-related tension of the limb. Do not do excessive exercise for a few days before the test to prevent muscle soreness and affect the test results. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Do not do excessive exercise for a few days before the test to prevent muscle soreness and affect the test results. Normal value Muscle rigidity and muscle weakness did not occur during the examination. Clinical significance Abnormal result 1. Increased muscle tone: the muscles are hard, the resistance to passive movement increases, and the range of joint motion is reduced. Can be expressed as sputum or tonic. (1) Increased spasm muscle tension: At the beginning of passive exercise, the resistance is large, and the sudden feeling is weakened at the end, which is called claspknife phenomenon, which is seen in pyramidal beam damage. (2) Increased tonic muscle tone: refers to an increase in the tension of a group of antagonistic muscle groups. When passive exercise is performed, the muscle tension of the extensor and flexor muscles is equally enhanced, as is the bending of the lead tube, so it is called the lead tube-like rigidity, which is seen in the cone. In vitro damage. For example, on the basis of the enhancement of myotonic muscle tension, there is tremor. When it is passive, there may be a feeling of gear-down, called cogwheelrigidity. 2. Reduced muscle tone: muscle relaxation is soft, resistance decreases or disappears during passive exercise, joint movement range expands, and sometimes excessive flexion and extension. Found in peripheral nerves, spinal cord anterior horn gray matter and cerebellar lesions. People who need to be examined are suspected of having abnormal muscle tone. Precautions Taboo before the test: Do not do excessive exercise for a few days before the test to prevent muscle soreness and affect the test results. Requirements for inspection: The muscles should be relaxed during the examination so that the doctor can carry out the inspection smoothly. Inspection process Inspection method: When the patient's muscles are slack, the doctor's hands hold the patient's limbs, and with repeated speeds and rotations with different speeds and amplitudes, the slight resistance felt is the muscle-related tension of the limb. The passive movement of each limb and joint was performed in the same way and compared on both sides. Secondly, the muscle is touched by hand, and the muscle tension can also be measured from its hardness. Not suitable for the crowd Inappropriate population: Patients with disabilities on their limbs or disease. Adverse reactions and risks Nothing.
