Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Ability to perform different activities assessed by DBS-QOLs

    Ability to perform different activities assessed by the Dystono-dyskinetic Brethomé-Sanrey Quality of Life scale (DBS-QOLs) with the evaluation of the ability to perform different activities (from impossible to autonomous) and then to estimate the evolution of this ability since the intervention (worsening, no change, improvement)

    1 year

  • Psycho-social assessment by DBS-QOLs

    Psychosocial assessment by the "Dystono-dyskinetic Brethomé-Sanrey Quality of Life scale" (DBS-QOLs) with yes/no/partially questions related to the emotional and psychological perception of patients and then to estimate the evolution of this thought since the intervention (worsening, no change, improvement)

    1 year

  • Intervention's assessment by DBS-QOLs

    Intervention's assessment by "Dystono-dyskinetic Brethomé-Sanrey Quality of Life scale" (DBS-QOLs) with yes/no question related to the intervention.

    1 year

  • Life's Quality assessment by DBS-QOLs

    Life's Quality assessment by "Dystono-dyskinetic Brethomé-Sanrey Quality of Life scale" (DBS-QOLs) with squales from 0 (worst case) to 10 (best case).

    1 year

Secondary Outcomes (7)

  • External validity of the DBS-QOLs compared to the BFMDRS for the functional subscale
