ELECTROTHERAPY 285 



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

 in 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 will 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 spinal cord is either treated longitudinally, with the anode placed upon the 

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

 versely, with the electrodes upon the sternum (anode) and spinal column 

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

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

 and to the forehead, the weakest galvanic ciurent possible being used. 



A more complete discussion of electrotherapy will be found in Grundriss 

 der Elektrotherapie f iir Tierarzte by Tereg (Berlin, 1902), and in the special 

 works of Erb, Pierson-Sperling, 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 im- 

 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 electric warm-current healing apparatus called the "Stangerotherm" has 

 been reconmiended for animals.
