BackgroundThe rising prevalence of Parkinson disease and the growing demand on the health care system underscore the need for accessible and innovative care solutions, such as Reality Digital Therapeutics (Reality DTx)-an augmented reality neurorehabilitation program that delivers remotely prescribed gait and balance exercises for people with Parkinson disease to perform at home.ObjectiveAt a preimplementation stage, this qualitative study aimed to explore the acceptability of Reality DTx.MethodsAn exploratory qualitative study design was used. We conducted semistructured interviews, guided by the theoretical framework of acceptability, with 22 people with Parkinson disease who used Reality DTx at home for 6 weeks as part of a feasibility trial. We conducted a reflexive thematic analysis using an inductive, semantic approach informed by critical realism.ResultsThe results of the reflexive thematic analysis are described in 3 themes and 9 subthemes. The 3 themes are "there was considerable interindividual variation," "the intervention is complementary to supervised physical therapy," and "adherence in the long term is crucial." Participants reported variable perceptions of effectiveness and variable experiences of effort to complete the Reality DTx program. They viewed Reality DTx as a valuable complement to supervised physical therapy and emphasized the indispensable role of the physical therapist for external control of long-term exercise adherence and for meaningful feedback on motor performance, as well as the desire for social connection. Flexibility in time and location was mentioned as a very important program characteristic, supporting long-term exercise adherence. Suggestions for improvement included enhanced visibility of progression in scores, increased variation in games, and the integration of competitive elements.ConclusionsRemotely prescribed, gamified, augmented reality exercises at home, complementary to supervised physical therapy, are acceptable to people with Parkinson disease. The findings inform future Reality DTx development and implementation from the perspective of people with Parkinson disease, which should be weighted with the perspectives of other stakeholders such as clinicians and other key decision-makers.
