Abstract

I.Introduction. II.Factors Concerned in the Diagnosis of Peripheral Nerve Lesions. A. Slight Motor Function Distinguished from Complete Paralysis. B. Relative Value of Various Observations. 1. Trophic Phenomena. 2. Electrical Reactions. 3. Sensory Changes. 4. Motor Loss. ( a ) Tendon Palpation. ( b ) Observations of the Muscle. ( c ) Joint Action. III.Production of Compensatory Movements. A. Compensatory Movements Produced by Momentum. B. Gravity as a Factor. C. Relaxation of Functioning Muscles. D. Contraction of Nonparalyzed Muscles. E. Elimination of Compensatory Movements by Proper Methods of Examination. IV.Lesions of Individual Nerves Considered in Reference to Compensatory Movements and Other Phenomena. A.
