Parkinson's disease is a neurodegenerative chronic condition with a declining trajectory and lack of a cure, making quality of life an important aspect of care. The purpose of this literature review was to analyze the state-of-the-science on the effects of non-pharmacological treatments on quality of life in person's with Parkinson's disease. Literature search was conducted using keywords in electronic databases up to September 1, 2016 and cross-searching the references of identified articles. Of the 259 articles generated, 26 met the eligibility criteria and were included in this review. The majority of studies (77%) were Level I evidence and 23% Level II evidence. The levels of study quality were: strong (50%), moderate (15%), and weak (35%). The interventions varied across studies with 15 studies evaluating a similar intervention. About 58% of the studies showed that the interventions improved quality of life. In conclusion, a variety of non-pharmacological interventions have been increasingly studied for their effects on quality of life in Parkinson's disease, showing initial promising results. However, most interventions were only examined by a limited number of studies and the minimal and optimal intervention doses needed for improving quality of life are yet unknown.
