BIOLOGICAL PERCEPTION OF HUMAN MOVEMENT IN INDIVIDUALS WITH PARKINSON'S DISEASE: A CROSS-SECTIONAL STUDY

Resumo

Parkinson's disease (PD) is a multifactorial neurological disorder, with progressive degeneration and impairment of voluntary motor control. Action-observation could be an effective way to learn specific motor skills, but in PD the execution of movement and biological perception of human movements could be affected by the difficulty to planning motor actions. The aim of this cross-sectional study was to evaluate the biological perception of human movement in individuals with PD (PDG, n=5), comparing it with a control group of healthy individuals (CG, n=5). Edinburgh Handedness Inventory (EHI) and Mini Mental State Examination (MMSE) were used to characterized both groups. PDG and CG were evaluated in a single session of 30 minutes by a Human Movement Perception Task, in which the primary outcome measure was the number of correct answers (NCA) in each movement perception task and the verbal reaction time (VRT). As a secondary outcome measure, the Hoehn and Yahr Scale (H&Y) and section 3 of the Unified Parkinson's Disease Assessment Scale (UPDRS) were used only in PDG. Statistical analysis was performed using the BioEstat 5.3, using Mann-Whitney test and Spearman correlation. No statistical difference (p>0.05) was found when comparing the NCA of each task among the groups. A negative correlation (rs:- 0,91; p=0.0304) was found between the H&Y and NCA for kick, long jump, sit to stand and riding a bike tasks. Further studies should be carried out based on the H&Y classification and its impact on the perception of human movement in this population. This study showed that there were no impairments in the perception of human movement by individuals with Parkinson's Disease. This study is ongoing.
