ELECTROTHERAPY 285 



close as possible to the paralyzed nerve or muscle, while the other one is applied 

 m the neighborhood. In spinal paresis of the posterior quarters an electrode 

 IS placed on the moistened sole of each hind foot so that the current wiU pass 

 through the entire posterior parts; in paralysis of a single limb, one electrode 

 IS apphed to the sole of the foot and the other in the region of the lumbar cord 

 The spmal cord is either treated longitudinally, with the anode placed upon the 

 upper (anterior) and the cathode upon the lower (posterior) part; or trans- 

 vei^ely with the electrodes upon the stemmn (anode) and spinal column 

 (cathode); the galvanic current, with the largest electrodes possible, operates 

 best. The brain is treated with the electrodes apphed to the back of the neck 

 and to the forehead, the weakest galvanic current possible being used 



A more complete discussion of electrotherapy will be found in Grundriss 

 der Elektrotherapie fiirTieriirzte by Tereg (Berlin, 1902), and in the special 

 works of Erb, Pierson-Sperhng, Rosenthal, Benedikt, Levandowski, Meyer 

 Graupner and others. ' 



Thermopenetration.-This term refers to the generation of heat in the 

 inner parts of the body with the assistance of the electric current. The un- 

 limited high-frequency current can be introduced into the body in any strength 

 desired without producing any effect upon the nervous system. It exerts a 

 favorable influence on man, especially in neuralgias and rheumatic affections 

 An electnc warm-current healing apparatus called the "Stangerotherm" has 

 been recommended for animals.
