Feasibility, Acceptability, and Usability of a Tele-rehabilitation Combining Immersive Virtual Reality Exercises and Therapeutic Education for Chronic Non-specific Neck Pain

Background: Several randomized controlled trials have already investigated the efficacy of virtual reality treatment for chronic neck pain, however no study to date has investigated multimodal tele-rehabilitation, combining both specific neck exercises in immersive virtual reality and therapeutic education, in subjects with chronic non-specific neck pain.

Objectives: The primary objective of this mixed-methods pilot study is to determine the feasibility, acceptability, and usability of tele-rehabilitation combining immersive virtual reality exercises and therapeutic education in people with chronic non-specific neck pain. Secondary objectives are: 1) to investigate changes in clinical outcomes (range of motion, pain intensity, neck disability, illness perceptions, kinesiophobia, impression of change) ; 2) to explore the subjects' experience of tele-rehabilitation.

Methods: The duration of the intervention will be 6 weeks, including 5 virtual reality sessions (15-20 minutes per session, without supervision of the physiotherapist) and 1 teleconsultation session with a physiotherapist (30 minutes per session) per week. Participants will be assessed quantitatively before and after the intervention, and qualitatively after the intervention.

Discussion: Study findings will provide evidence concerning the feasibility, acceptability, and usability of multimodal tele-rehabilitation for chronic non-specific neck pain, using immersive virtual reality. This study may strengthen the scientific evidence for the use of immersive virtual reality at home in the treatment of chronic non-specific neck pain.
