This two-volume work is the first and only complete description of the use of tiny electronic signals for the treatment of neuromuscular injuries, including neck and back pain, rotator and ACL tears, carpal tunnel and the rapid repair of traumatic injuries. The book covers the underlying principles of neurophysiology, cell function and dysfunction, and a compete discussion of the electro-chemical process that governs our every movement and function. Finally, this book describes in detail the implementation and the techniques used in diagnosis and treatment of injury using up-to-date electro-therapy. The SCENAR, which is the most useful tool for the application of this technology, is described in detail. Use of the SCENAR in many applications is described, along with results obtained from its use. The two volumes consist of 451 and 417 pages, with full color pictures and illustrations in a soft cover 6 x 9 inch format.
