Cerebellar dentatotomy was a procedure widely used in the past to treat generalized spasticity. Their results were never excellent enough to bring near complete improvement to the applied cases. On average, there was a 50% improvement in symptoms. Few better results were obtained when the technique was combined with thalamotomy. This technique is currently in disuse. One technique still in use for the treatment of selected cases of spasticity and dystonia is deep brain stimulation in the dentate nucleous, a technique with still uncertain results. A non-invasive option for dentate nucleous stimulation is by Magnectic Transcranial Stimulation.
