Abstract
Abstract An apparatus for therapeutical treatment and stimulation of muscles in a human body comprises a housing containing a low-frequency oscillating electric circuit having dry cells as power source and an electrode section having two electrodes electrically connected and replaceably associated with the housing. The apparatus has a construction of compact and small size adapted for therapeutical and stimulating treatment by electric charge applied to the muscles with the electrode section contacted to muscle portions so as to remedy pain and fatigue in the muscles and strengthen the muscles by stimulation.
