Parkinsonian syndromes are common causes of gait disorders, associated with hypometria, bradykinesia or rigidity. If motor disorders are the most visible part, lower urinary tract dysfunction is one of the most prevalent dysautonomic disorder (27-80%), especially over active bladder syndrome (OAB). If it seems evident that gait and urinary disorders are linked, because of similar anatomic pathways and control processes, no studies have investigated their association in extrapyramidal patients.
