Motor skills are motions carried out when the brain, nervous system, and muscles work in concert. The cerebellum is deeply interconnected with sensory-motor areas of the cerebral cortex. Cerebellar ataxia and motor-based neuropathy damage both contribute to the loss or impairment of motor skills.
Cerebellar ataxia affects fine motor skills, small movements like opening a jar, holding a fork, cutting your food, or using a small tool. Fine motor skills use the muscles in your fingers, hands, wrists, toes, lips, and tongue.
Motor-based neuropathy affects the gross motor skills, the large muscles in the arms, legs, torso, and feet. These skills are responsible for bigger movements like sitting, standing, walking, running, and balance.
