Safety Predictors in Performance of Activities of Daily Living in Patients with Parkinson’s Disease

Background: Safety is recognized as an important factor in personal independence. Studies have found a significant relationship between ADL safety and fatigue, disease severity, and age and considered them to be predictors of performance safety in ADL among patients with PD. But they didn’t consider the cognitive, motor skill; motivation and mental state for safety performance of ADL and suggested further research in this area. Aim: Therefore the aim was to determine safety predictors for ADL in persons with Parkinson's’ Disease. Methods: An observational association-analysis design was applied for the study. Thirty three patients with PD participated in this study. Cognition was assessed using SCOPA, motor and mental scores were assessed using UPDRSI and III scale, motivation was assessed using AES scale, while performance safety was examined with the performance assessment of self-care skills (PASS). Results: A significant relationship was observed between ADL safety and cognition (r, 0.645; P < 0.001), mental state (r, -0.512; P < 0.001), and motor (r, -0.607; P < 0.001).But no correlation with apathy (r,-.312;P=0.78) Conclusion: Cognition, mental state and motor performance are predictors of performance safety in ADL among patients with PD. For implementing more effective interventions on safe ADL performance, rehabilitation teams should conduct more detailed safety assessments with a special focus on the effects of cognitive, mental state and motor on the performance of each activity.
