Participant Flow

Participants were recruited via online (e.g., social media) advertising between December 2019 and September 2020. The first participant was enrolled on June 9, 2020, and the last participant was enrolled in October 2020.

Of 1,346 applicants, 270 met inclusion criteria. Of these, 72 were enrolled in the study; however, 11 withdrew before start / randomization. 61 participants started the study (completed randomization). After a 2-week baseline period, participants were randomized into the Experimental and No Intervention Groups.

Measure
Therapy Group
Therapy Group participants start the treatment period with three 1 ½ hour introductory sessions: 1. An education session on the science behind chronic pain and a basic overview of the VR therapy. 2. A session to customize the VR experience to match the participant's own pain experience. 3. A training session on the use of the VR hardware and software. Upon completion, participants begin using the VR therapy app at home once a day, 5 times a week (minimum), for a total of 8 weeks. The VR app contains different training exercises. A workbook provides a schedule and background on each of the training sessions. Therapy Group participants may continue their other pain treatment regimes, and are asked to notify the research team of any changes.

Standard of Care (SOC) Group
The SOC Group (no-intervention) completes a daily pain survey. SOC Group participants are asked to maintain their pain treatment regimes, and are asked to notify the research team of any changes.

SECONDARY outcome

Timeframe: Baseline (average of survey data at beginning and end of a 2-week baseline period) and at the end of the 8 week therapy / control period.

Population: Intent to Treat

Quality of Life (HRQoL SF-12) Questionnaire: yes / no questions and 3-point / 6-point Likert Scale questions; e.g., 1 = \[negative impact\] all of the time (worse outcome), 6 = \[negative impact\] none of the time. HRQoL results in two sub-scales / components (Physical and Mental). The mean of these was taken to result in a single value.

Population: Intent to treat

Oswestry Low Back Pain Disability Questionnaire (OLBPD). 6-point Likert Scale questions on impact of pain on various life aspects; e.g., 1 = no negative impact, 6 = prevents normal activity (worse outcome). Participants completed questionnaire at the beginning and end of a 2-week baseline period and at the end of the 8 week therapy / control period. The starting values were the average of the two reported pain measures at the beginning and end of the baseline period
