Electrical Charge Now Charts Polio

A new method of investigating the causes of polio by measuring the amount of electricity in the muscles of victims was revealed yesterday by Dr. Arthur L. Watkins '31, associate in Medicine.

Dr. Watkins discussed the new technique, known as electromyography, at a meeting of the American Academy of Orthopedic Surgeons in Chicago.

Since completely paralyzed muscles are usually electrically silent, he disclosed, doctors can foresee a patient's recovery when electrons begin to reappear. The technique can be used to expose malingerers and to reassure neurotics.

The electrical activity in afflicted muscles is greatest when the patient is relaxed, Dr. Watkins declared, and when the patient moves, electrical fluctuations can be detected.

Dr. Watkins and his associates are also applying their findings to certain types of ruptures and Parkinson's disease.
