A Comprehensive Exploration of Motor, Sensory, and Physiological Factors in a Case of Limb Kinetic Apraxia Following...

We herein report a 16-year-old boy who presented with limb-kinetic apraxia, which was presumed to be an impairment of sensorimotor integration due to brain damage localized to the central region after head trauma. The patient's basic sensory and motor functions were also preserved. However, deficits were noted in two-point discrimination (a higher-order sensory function), material identification, and three-dimensional geometric figure identification: sensorimotor tests that include active touch (a function of sensorimotor integration). The present case suggests that a thorough neurological examination from the perspective of sensorimotor integration is important to understand the pathology of limb-kinetic apraxia.
