The objective of this study is to assess the origins of lateral postural inclination presented by some Parkinson disease's patients. Several mechanisms could cause lateral postural inclination. Available data allow to suggest three hypothesis: (troubles of tonus, perception of vertical perturbation, trouble of perception of corporal axis
Inclusion Criteria: * 30 to 75 years old patient * Parkinson disease's diagnosed since 5 years * Treated by deep brain stimulation * Patient with at least 6 degree lateral deviation * Without vestibular troubles nor peripheral sensorial trouble. Exclusion Criteria: * Dementia (Mattis \< 130 ou MMS \<24), or severe depressive episode according to DSM IV-R criteria * Camptocormia or incompatible anteflexion with the dispositive of measure device * Pregnant woman, nursing mother
