Parkinson's disease is a chronic, neurodegenerative disease of unknown cause, affecting elderly people over the age of 60. It is the second most common neurodegenerative disease, presenting psychomotor signs and symptoms that lead to impaired functionality and quality of life in affected individuals. Mixed reality involves the delivery of digital stimuli in real time and space through spatial mapping using glasses, safely providing multiple iterations to carry out daily activities. Through this tool and in collaboration with technologically skilled mixed reality developers, the software for the rehabilitation program to be applied to Parkinson's disease patients was also developed. The main objective of this clinical study is to examine the effect of a mixed reality program compared to a traditional physiotherapy program on quality of life and motivation for the participation of people with Parkinson's disease.
