ROHKEA: Virtual Reality Therapy 12-week Programme for Chronic Pain

The ROHKEA Virtual Reality (VR) Therapy device is specifically aimed at people with low activation and low motivation, who are unable to attend outpatient clinics or access online support. The ROHKEA VR Therapy device is offering something current standard of care cannot. This enables people to engage with CBT and exposure therapy for chronic pain using VR therapy to enhance motivation and attention, whilst in the safety and comfort of their own home.

This is a pilot study using an Interpretative Phenomenological Analysis (IPA) design and semi-structured interviews: to explore the experience of 6 patients with chronic pain going through a VR enhanced CBT and graded exposure 12- week chronic pain management programme. The verbatim transcripts of those interviews will be used as the data for an IPA. Participants will be asked to keep a rolling diary of their experience across the 12-week programme - and to re-read this prior to the interview at the end. They will also be asked to keep a home practice log via a mobile app. Participants will be recruited following the completion of a telephone healthcare assessment which is standard practice. Participants who express an interest in the study will be screened to ascertain their willingness to learn new skills despite pain; ensure they satisfy the inclusion criteria, and are able to safely use a Virtual Reality device. A clinical assessment will be completed as part of this process and treatment goals identified with each participant. Participants will be invited to trial a Virtual Reality headset device in their own home, and will already have completed a VR screening tool to ascertain their medical health, and to satisfy infection control measures. A 2-stage consent process is required: one for screening and then a consent to enter the trial. ROHKEA™ VR Therapy and ROHKEA™ Companion application forms the ROHKEA™, which is intended to be used by people living with chronic musculoskeletal pain. ROHKEA™ VR Therapy is a virtual reality (VR) experience designed with pain management and pain psychology professionals to provide digital therapeutic content for people with chronic pain to treat fear of movement and improve pain management in daily life. ROHKEA™ VR Therapy consists of a 12-week long treatment program including psychological therapeutic modules as well as physically activating exercises specifically designed for people with chronic musculoskeletal pain. The whole program is guided by a built-in virtual mentor (SAMI). The headset is an oculus quest 2 virtual reality device. An elite strap is being used for comfort, and the hand controllers have the choice of additional Velcro straps for ease of use and comfort.

ROHKEA™ Companion application is a support tool to complement the OHKEA™ VR Therapy. It is designed to provide easy access to account management, progress tracking, homework, and extra materials. Three standardised self-report questionnaires, which are part of standard of care will be used. They will be completed at assessment, pre and post the 12-week programme. They include:

1. Brief Pain Inventory (BPI) - measures pain severity, the impact of pain on daily function, the location of pain, pain medications and amount of pain relief in the past 24 hours of past week. There is no scoring algorithm for the Brief Pain Inventory, but "worst pain" or the arithmetic mean of the four severity items can be used as measures of pain severity; the arithmetic mean of the seven interference items can be used as a measure of pain interference.
2. Chronic pain acceptance questionnaire - short version 8 (CPAQ8) to identify different profiles of pain acceptance patterns, levels of function and behavioural flexibility.
3. Patient Health Questionnaire - short version 4 (PHQ4) is four questions answered on a four point Likert-type scale. Its purpose is to allow for ultra-brief and accurate measurement of core symptoms/signs of depression and anxiety.

Participants will be encouraged to keep a journal/log of their experiences throughout the 12-week programme. They will be able to choose their own format for completing this. It is intended as an aide memoir to read though at the end of the programme, prior to completing an in-depth interview with the research team. Participants will be interviewed in person 1-2 weeks post completing the programme. The session will be recorded and a transcript generated. Participant characteristics and chronicity of pain will be noted. Themes will be generated from the transcripts, and connections will be sought. A more thorough and analytical ordering of the data will follow, as the researcher aims to make sense of what the person is saying. Superordinate themes will be identified, and care will be taken to distinguish between what the respondent said and the analysts interpretation of it.
