Understanding Physical Therapy Challenges for Older Adults through Mixed Reality

Abstract: Physical therapy (PT) is crucial in helping older adults manage chronic conditions and weakening muscles, but older adults face increasing challenges that can impact their PT experience, including increased fatigue, memory loss, and mobility and travel constraints. While current technology attempts to facilitate remote care, they have limitations and are used in-practice infrequently. Mixed reality (MR) technology shows promise for addressing these challenges by creating immersive, context-aware environments remotely that previously could only be achieved in clinical settings. To bridge the gap between MR's potential and its practical application in geriatric PT, we conducted in-depth interviews with three PT clinicians and six older adult patients to understand challenges with PT care and adherence that MR may address. Our findings inform design considerations for supporting older adults' needs through MR and outline technical requirements for practical implementation.
