Which term describes an uncoordinated gait associated with pathology of the central nervous system?

Ataxic gait is characterized by a lack of coordination, balance, and control during movement, which is often seen in individuals with central nervous system pathology. Conditions that can lead to an ataxic gait include cerebellar disorders, multiple sclerosis, and stroke, where the cerebellum or its connections are affected, impairing the ability to execute smooth, coordinated movements. The key aspect of ataxia is the inability to precisely control the timing and sequencing of muscle contractions, leading to a staggered or unsteady walk.

Other terms listed describe different aspects of motor function. Spastic gait is marked by stiffness and resistance to movement due to increased muscle tone, typically related to upper motor neuron lesions. Hypotonic conditions refer to decreased muscle tone, often resulting in a flaccid or weak appearance and movement. Apraxic gait involves difficulties in motor planning and execution of coordinated movements, which can occur even when strength and sensation are intact. Each of these conditions has distinct characteristics that differentiate them from ataxia, which is specifically tied to uncoordinated movement patterns due to central nervous system dysfunction.
