Introduction: Parkinson’s disease is a neurodegenerative disorder leading to the loss of independence and deterioration in patients’ quality of life. In recent years, researchers have developed various forms of rehabilitation as a support strategy alongside drug treatment. It has been suggested that music therapy can have a positive impact on both cognitive and motor function in Parkinson’s disease patients and, more importantly, improve quality of life. Aim of the study: The purpose of this systematic review was to assess the latest research and summarise the possibilities and effectiveness of music therapy. Materials and methods: Four databases were systematically searched and analysed from 1 January 2021 to 14 February 2023, according to the established criteria and definition. Results: Thirteen studies were included in the analysis. The methodology of the studies varied. Most of them were short-term and involved a small number of participants. Studies examining the impact of singing, dancing and playing instruments, were included in the analysis. Of the studies, 69.2% reported positive effects on motor function, 84.6% on cognitive function, and 53.8% on improved mental well-being. Conclusions: Although the research methodology needs further refinement, the benefits of music therapy on motor, cognitive, and mental functioning are evident in short-term studies. The potential beneficial effects in long-term follow-up require further research.
