Poorly controlled chronic pain in teens can impact quality of life, increase opioid use and is a risk factor for developing chronic pain in adulthood. Currently, there is a shortage of support to help teens manage chronic pain in the community and the support that did exist has been significantly scaled back due to the COVID-19 pandemic. This research study will investigate, based on questionnaires with teens and healthcare providers and interviews with teens, whether pain rehabilitation virtual reality is easy to use and understand, satisfactory to use, and whether it may improve pain, mobility, and function for the teens using the program compared to those doing standard physiotherapy treatment over videoconference.

Chronic pain affects the lives of 1 in 5 - or 2 million - Canadian children and adolescents and has negative impacts on all aspects of health-related quality of life as well as significant economic costs to families and society. The standard of care for pediatric chronic pain management is an interprofessional biopsychosocial treatment approach, a cornerstone of which is physiotherapy (PT) led functional rehabilitation. Furthermore, lack of access to pain clinics and physiotherapy is an ongoing issue which has been exacerbated by the current COVID-19 pandemic; many ambulatory pediatric chronic pain clinics and community-based physiotherapists have halted appointments, with only a few pivoting to virtual service delivery. Providing care virtually is particularly challenging in this field given the physical and hands-on nature pain physical therapy assessment and treatment. These challenges delay treatment and leave vulnerable youth at risk for severe sequelae without the services they require for recovery.

Virtual reality (VR) can help bridge these gaps in care during and beyond COVID-19 by reducing fear associated with movement. A growing body of research has shown the power of immersive VR for reducing anxiety and managing acute pain via distraction in children and adolescents. While there is emerging evidence for the benefit of VR for treating chronic pain in adults, there is minimal research evaluating VR's effectiveness for reducing pain and improving physical function in children and adolescents with chronic pain. Changes to health service delivery due to the COVID- 19 pandemic confirms the crucial need to develop a comprehensive, engaging, and effective approach to home-based chronic pain rehabilitation. The ability of VR to offer patients with chronic pain access to multi-sensory, 3D, immersive therapeutic experiences, has the potential to break the cycle of pain, fear and activity avoidance from a patient's own home.

This pilot randomized controlled trial (RCT) will: (1) Primary Aim: determine the feasibility of implementing an off-the-shelf VR program and custom VR program (i.e., accrual rates, engagement in therapy sessions, retention rates, technical and practical issues, time to set up and conduct PR-VR, treatment acceptability, outcome evaluation, adverse events and participant satisfaction) and; (2) Secondary Aim: evaluate preliminary effectiveness (estimates of magnitude of effect) of VR interventions compared to the usual care condition (standard virtual PT [SVPT]).
