Chronic pain in older adults is a complex and multidimensional condition that affects physical function, emotional well-being, social participation, and overall quality of life. In this population, persistent pain is frequently accompanied by fear of movement and maladaptive beliefs about pain, which can lead to activity avoidance and progressive functional decline. Many older adults reduce their physical activity not only because of pain itself, but because of the anticipation that movement will worsen symptoms or cause injury. Over time, this avoidance can contribute to muscular deconditioning, reduced balance, increased frailty, and greater dependence in daily activities. Contemporary pain science recognizes that chronic pain involves not only peripheral tissue factors but also central nervous system processes, cognitive appraisal, emotional regulation, and learned behavioral patterns. For this reason, rehabilitation approaches that address only the physical dimension of pain may be insufficient.
This study is grounded in the biopsychosocial model of chronic pain, which integrates biological, psychological, and social contributors to the pain experience. The intervention is designed to engage these interacting domains simultaneously. On a biological level, gradual activation of the motor system and re-engagement in movement may help counteract deconditioning. On a psychological level, addressing maladaptive pain beliefs and reducing fear-based avoidance may improve confidence and perceived control. On a social and emotional level, increasing engagement and exposure to meaningful environments may support mood and motivation.
Pain neuroscience education has demonstrated benefits in reducing catastrophizing and improving self-efficacy in individuals with chronic pain. Structured educational programs that explain how chronic pain differs from acute injury and how the nervous system can become sensitized may help individuals reinterpret their symptoms in a less threatening way. When patients better understand that pain does not always indicate tissue damage, they may become more willing to re-engage in movement. The educational component included in this study is intended to provide participants with practical strategies to manage flare-ups, regulate stress responses, and reduce unhelpful thoughts related to pain.
In parallel, immersive virtual reality offers a novel therapeutic platform capable of supporting graded exposure to movement in a controlled and engaging manner. Immersive virtual environments create a strong sense of presence, meaning that users feel situated within the simulated environment rather than observing it from a distance. This immersive quality may increase attentional absorption, reduce pain salience, and enhance emotional engagement. Virtual environments can also provide positive and calming experiences, including exposure to natural landscapes, which have been associated with improved mood and reduced stress. In addition, interactive virtual systems can translate gentle physical movements into forward progression within the environment, allowing participants to experience movement success in a supportive context.
The intervention evaluated in this study integrates structured pain education with immersive virtual reality-supported rehabilitation delivered under clinician supervision. The virtual component is personalized and adapted to the participant's functional capacity, preferences, and rehabilitation goals. The progression within the immersive experience is gradual. Participants may begin with exposure to immersive environments that require no active physical movement, allowing them to become comfortable with the technology and to engage in guided motor imagery. As confidence increases, the intervention may incorporate gentle physical movements that influence navigation within the virtual space. This graded approach is designed to reduce fear while reinforcing positive movement experiences. The immersive environments are selected to promote safety, engagement, and enjoyment, with careful monitoring for tolerability.
The primary purpose of this pilot study is not to establish definitive clinical efficacy, but rather to evaluate feasibility, acceptability, and implementation practicality in older adults with chronic pain. The study seeks to determine whether the combined approach can be delivered safely within clinical and residential care settings, whether participants are willing to engage with immersive technology, and whether clinicians can integrate the intervention into routine workflows. The study also aims to estimate variability in key clinical measures in order to inform sample size calculations for a future larger trial.
Several conceptual mechanisms may contribute to potential benefit. Engagement in immersive environments may reduce attentional focus on pain, temporarily lowering perceived intensity. Guided motor imagery and graded movement may activate motor-related neural networks without triggering excessive threat responses. Repeated positive movement experiences may weaken fear-based associations. Educational content may modify maladaptive beliefs and reduce catastrophizing. Improvements in confidence and perceived control may facilitate behavioral activation and adherence to rehabilitation. Exposure to calming natural environments may influence mood and stress regulation. These interacting processes reflect the integrated biopsychosocial rationale of the intervention.
The pilot design allows systematic documentation of recruitment flow, adherence patterns, participant retention, tolerability of immersive exposure, and practical barriers to implementation. The study also examines whether older adults with varying levels of physical function and technological familiarity can engage with immersive systems when provided appropriate supervision and support. Safety considerations are central, including monitoring for cybersickness symptoms such as dizziness, nausea, or disorientation. The intervention is delivered under trained supervision, and participants may discontinue at any time without impact on usual care.
By focusing on feasibility and implementation in real-world contexts rather than tightly controlled laboratory conditions, the study aims to generate information that is directly relevant to clinical translation. The results will inform refinement of procedures, optimization of session pacing, identification of appropriate safety parameters, and clarification of training needs for clinicians. Ultimately, this pilot phase is intended to support the development of a larger, adequately powered randomized controlled trial designed to evaluate the clinical effectiveness of immersive virtual reality-supported rehabilitation for chronic pain in older adults.
