Lack of voluntary coordination of muscle movements results a neurological sign known as ataxia. Disturbances of ataxia are failure to produce smooth intentional movements; inability to perform smooth coordinated gait, weakness, dizziness, stroke, falling etc., Ataxia is of three typeâs motor ataxia, sensory ataxia, vestibular.
Motor ataxia caused by cerebella disorders, intact sensory receptors and afferent pathways.
Integration of proprioception is faulty, midline cerebellar lesions cause truncal ataxia, lateral cerebellar lesions cause limb ataxia, and thalamic infarcts may cause contralateral ataxia with sensory loss.
Sensory Ataxia is due to failure of proprioceptive information to the CNS, may be due to disorders of spinal cord or peripheral nerves or can be compensated for by visual inputs.
Vestibular ataxia is an ataxia caused due to dysfunction of vestibular system, followed with the symptoms of nausea, vertigo, vomiting.
Some drug treatments, physical therapy, occupational therapy, movement therapies are used to treat ataxia up to some extent.
