Spasticity is defined as increased resistance to passive stretch where the central feature is an exaggerated stretch reflex. In the experimental animal this clearly delineates spasticity from the general category of hypertonic states and muscular rigidity. In clinical practice the distinction is not so readily apparent. However, the author of this short monograph proposes some interesting hypotheses for the mechanism of spasticity in man, correlating clinical observations with the results of the investigation of the muscle spindle and the gamma motor system in animals. Similarities and discrepencies are discussed. The anatomy of the stretch reflex is reviewed, and the contributions
