This short monograph presents in considerable detail a method of treatment of hemiplegia and other upper motor neuron disorders by means of active exercises. These include methods of teaching walking and rhythmic exercises for coordination with minimal apparatus. To develop functional ability of the upper extremities the most important equipment is three sizes of balls used in exercises and games. Other standard gymnasium equipment is also described and advocated. A few types of occupational therapy procedures are included. The complete problem of rehabilitation of these patients including social and economic adjustment is not fully covered. Physicians and technicians dealing with these problems will find practical information satisfactorily described and illustrated. It is recommended more as a reference textbook, as it does not completely cover the problems in this important field of physical rehabilitation.
