RESUMO
OBJECTIVE: Virtual reality (VR) can enhance engagement in outpatient physical therapy (PT) through distraction and gamification of movement. This study assessed barriers and facilitators to VR-enhanced PT. METHOD: Data were collected during a feasibility trial of VR-enhanced PT for youth with chronic musculoskeletal pain. Semistructured and informal interviews were conducted with youth participants, their caregivers, and collaborating physical therapists. To analyze transcriptions, content analysis was employed in multiple rounds. Barriers and facilitators to VR implementation were coded using a deductive approach, then an inductive approach was used to identify emergent themes within each deductive code category. RESULTS: We completed interviews with youth participants (n = 9), caregivers (n = 7), and clinician stakeholders (n = 5). Coded barriers included: (1) participant identity and self-narrative inconsistent with the intervention, (2) system-level, structural constraints of healthcare, (3) lack of guidance and leadership from clinicians around VR use, (4) research burnout, (5) expectation violation and disappointment, and (6) missing the optimal treatment window. Coded facilitators included: (1) viewing VR as a bridge to achieving treatment goals, (2) having access to resources, (3) sustained positive experience and immersion in the game, (4) alignment between identity and the intervention, and (5) champion-level collaborations. CONCLUSIONS: This study highlights the importance of considering the VR technology, person using the VR, and the context in which VR is being implemented to optimize uptake and acceptability. Adopting an implementation science lens to the field of VR for chronic pain will enhance the applicability and scale of impact.
RESUMO
INTRODUCTION: Chronic pain affects a significant number of children and impacts multiple domains including social, emotional and behavioural functioning, and negatively impacts family functioning. Roughly 5% of youth with chronic pain experience moderate to severe pain-related disability, with pain-related fear and avoidance of activities being identified as substantial barriers to treatment engagement. Evidence supports targeted psychological and physical interventions to address these barriers (eg, graded-exposure treatment), but accessibility to intervention is undermined by a shortage of services outside of urban areas, high treatment-related costs, and long provider waitlists; highlighting the need to develop digitally delivered behavioural intervention, using agile and iterative study designs that support rapid development and timely dissemination. METHODS AND ANALYSIS: This study seeks to develop an effective and scalable intervention for youth with chronic pain and their caregivers. This paper presents a user-centred protocol for the development and refinement of a digital exposure treatment for youth and caregivers, as well as the study design to examine feasibility and preliminary efficacy of the treatment using single-case experimental design (SCED). Assessments include daily diaries, completed from baseline and daily throughout the intervention (~6 weeks), and at 3-month follow-up, as well as self-report measures completed at baseline, end of intervention and 3-month follow-up. Primary outcomes include treatment satisfaction, treatment expectancy, adherence to daily dairies and functional disability. Secondary outcomes are pain-related fear and avoidance of activities, pain catastrophising and pain acceptance. We will present descriptive and model-based inference analyses, based on SCED reporting guidelines. We will calculate effect sizes for each individual on each outcome. We will examine mean treatment expectancy, credibility and satisfaction scores, and patient drop-out percentage. ETHICS AND DISSEMINATION: This study is approved by the Institutional Review Board at Stanford University (protocol #53323). Findings will be actively disseminated through peer-reviewed journals, conference presentations and social media. TRIAL REGISTRATION NUMBER: NCT05079984.
