Abstract
Deep brain stimulation (DBS) in the nucleus ventralis intermedius thalami (VIM) is a common procedure to treat disabling tremor in multiple sclerosis which is refractory to pharmacological treatment. The sparse studies on DBS in multiple sclerosis tremor remain controversial regarding the clinical effect on postural and action tremor of hands, trunk and head. Furthermore, it remains unclear whether DBS in multiple sclerosis tremor is superior to thalamotomy and whether patients show an overall improvement in quality of life and activities of daily living. Therefore, the consensus recommendations of the German Deep Brain Stimulation Study Group rely primarily on expert opinion and include (1) extensive preoperative characterisation of tremor, ataxia with accompanying disabilities, status of the multiple sclerosis, co-morbidities and burden of disease, (2) careful intraoperative testing of effects and side effects and (3) intensive postoperative testing and programming as well as regular re-evaluation of the therapeutic effect.
