IS ELECTROSTIMULATION PREFERABLE TO SURGERY FOR UPPER-LIMB ATAXIA

Ataxic syndromes of the upper limbs are observed in various situations but are usually a result of lesions involving the efferent pathways o f the cerebellum, the superior cerebellar peduncles and midbrain. The commonest causes are multiple sclerosis, brain injury and focal neopla stic or vascular lesions. Cerebellar tremor, which usually comprises a postural and intentional component, is the commonest clinical form. I n this review, we assess the value of the various surgical techniques in the treatment of this particular form of ataxia of the upper limbs.
