The study was discontinued at the investigator's discretion due to recruitment difficulties. In addition, patient care and management practices have evolved, and the DBS-QoL questionnaire is no longer used in routine clinical practice.

In spite of a growing interest in the evaluation of health-related quality of life in movement's disorders management, there is no tool specifically dedicated to dystonia and related syndromes that measures both the objective severity of the handicap and the patient's feelings about the surgical treatment in terms of subjective improvement. We have been working for several years at the bedside of patients operated on in the " pathologies cérébrales résistantes " Unit on the development of a related questionnaire to assess both the motor severity and the patients' feelings about the evolution of their disease under Deep Brain Stimulation (DBS).
The self-questionnaire designed would allow to a certain extent to get away from the two gold standards currently used in the field, i.e. the Burke, Fahn & Marsden Dystonia Rating Scale (BFMDRS) and the SF-36, thus facilitating the evaluation and allowing a homogenization of the practices for the different implanting centers on the french territory.
The construction of the tool in its particular design, including various targeted modules, stems from an experience of more than ten years acquired with patients treated by deep brain stimulation in the unit. The self-questionnaire thus obtained will be sent to 146 patients with generalized dystonodyskinetic syndrome, operated and followed in the unit, and submitted to various statistical analyses. The scores of the identified dimensions will be compared with the etiology of the abnormal movements (primary vs. secondary) as well as with the results obtained with the two scales currently used to evaluate abnormal movements (BFMDRS) and/or quality of life (SF-36) and finally with the patients' mood during their follow-up (BDI, STAI). Tolerance to surgery will also be measured.
