Arm Tone Reaction

The arm tone response is a clinical test that measures the muscle tone of the upper limb. The results of the arm tone response can be used to diagnose and evaluate the treatment of neurological diseases such as myasthenia gravis, Parkinson's disease and others.

**Procedure** To carry out the arm tone reaction, it is necessary to ask the patient to extend his arm forward and slowly bend it at the elbow joint. The neurologist will monitor the range of motion of the shoulder joint and the strength in various muscles. Typically the hand tone reaction time is about two seconds. If any delay in reaction occurs, you should consult a doctor. **Normal results**

The hand tone response should be quick and complete. In the case of normal muscle function, there should be no significant difference in the range of motion between both hands.

If the muscle response is deviated when performing the Wodak Fisher test, additional studies should be performed: take an x-ray of the cervical spine, perform biochemical blood tests to determine the level of thyroid hormones, and examine the level of calcium. When all the results of the examination are received, in combination with the clinical examination of the patient, a final diagnosis will be given.
