Title: Postural response in patients with Parkinson's disease and healthy elderly on instrumented retropulsion test Introduction: Parkinson's disease (PD) is characterized by a dopamine deficit necessary to movement control. Thus, signs and symptoms motors arise, for example, postural instability, which has a small response for drugs therapy. Since PD patients show deficits in anticipatory and compensatory postural adjustment, the present study manipulated the expectation of an external disturbance with an instrument that replicated the retropulsion test (item 30 of the Unified Parkinson's Disease Rating Scale (UPDRS) called unexpected retropulsion test (URT) and the same test as expected (ERT) to expand knowledge of the compensatory postural reactions and postural instability. Objective: To investigate the compensatory postural reactions and balance recovery in healthy elderly and patients with PD through URT and ERT. Method: 34 subjects were evaluated (17 healthy elderly and 17 elderly with PD (stage 1 to 2.5 of the Hoehn & Yahr). For exclusion's criteria of the study, participants answered the anamnesis. For the screening of cognitive functions was used the Mini Mental State Examination (MMSE) and to assess the degree of involvement of the disease it was applied the UPDRS. For applications of URT and ERT, a device was designed and constructed to ensure the implementation of a customized force (5% of the participant body weight), ensuring the displacement of the center of mass (CM). When an expectation of external disturbance was manipulated, the first attempt was made unexpectedly to all participants and the other attempts (4) in the expected way. Spatiotemporal variables were calculated: the time from the beginning of the movement and removal of the heel from the ground, width, length and velocity of the recovery step; relative angles of the hip, knee and ankle at the beginning of the movement, and the time of removal of the...
