Brief summary
This study aims to evaluate a novel mediated reality intervention for clinical use in those with knee osteoarthritis. Previous work has shown that mediated reality can be used to deliver body re-sizing illusions that reduce knee osteoarthritis symptoms. Recently we have worked with end-users to develop a clinic-ready version of this technology. The overarching aim of this project to test the clinic-ready version of this technology and evaluate its feasibility, acceptability, and preliminary efficacy in those with knee osteoarthritis.
Interventions
All participants will receive the same intervention. Participants will attend 8, one-on-one, 1-hour sessions with a healthcare provider (physiotherapist, sports trainer, or exercise physiologist) over a 4-week period. All health providers will receive 4 hours of training by the research team on intervention delivery and trial activities. There are three components to the intervention: pain science informed knee osteoarthritis (OA) education; mediated reality bodily illusions; and self-paced cycl
All participants will receive the same intervention. Participants will attend 8, one-on-one, 1-hour sessions with a healthcare provider (physiotherapist, sports trainer, or exercise physiologist) over a 4-week period. All health providers will receive 4 hours of training by the research team on intervention delivery and trial activities. There are three components to the intervention: pain science informed knee osteoarthritis (OA) education; mediated reality bodily illusions; and self-paced cycling. Study adherence will be evaluated by session attendance and by counting the number of sessions where participants choose to use the mediated reality. The education will be delivered via bespoke videos to enhance standardisation across participants/sites. Educational concepts include: the 'modern' OA story (i.e., that knee OA is a whole body process, that symptoms can improve with lifestyle management); importance of exercise for knee OA; and the existing scientific evidence for bodily illusions. Videos will be played at the beginning of the session and are between 7-18 minutes in length. Clinicians will re-enforce the educational messages provided from the videos and answer any participant questions about the content. Next, clinicians will use the mediated reality to provide body re-sizing illusions. The mediated reality system uses bespoke software on a Microsoft Surface Pro (Redmond, WA, USA) tablet. In these illusions, participants view a live video of their own knee in a tablet and a bespoke program is then used to change the viewed morphology of the knee, either visually stretching/elongating or shrinking/compressing the live video of the participants knee in the tablet. While the visual changes are occurring on the tablet, the clinician provides gentle congruent tactile input to the participants lower leg (i.e., gently distracting/compressing the joint), These illusions will be customised to participants preferences to ensure the best reduction in knee symptoms (i.e., the number of repetitions, type of morphological change, degree of morphological changes). Participants will be offered stretch/shrink illusions prior to cycling every session. They may also choose to have 'top-ups' of the illusion during/after cycling. From session 3 onwards, participants will receive a strong leg illusion applied with mediated reality while the participant is cycling. Here, the participant will see a set of strong, muscled legs cycling in time with their own legs in order to induce ownership. From session 5 onwards participants will be provided the choice with which illusion they will receive. At each session, participants complete up to 30 minutes of self-paced cycling on a stationary bike mounted on a Wahoo Kickr Smart Trainer. Participants will self select both cycling cadence and resistance (controlled via the Wahoo app). Participants will cycle for as long as they are able/comfortable doing or for a maximum of 30minutes.

Inclusion criteria
Inclusion criteria include: persistent knee pain (duration >6months) of moderate intensity (average pain over the past week =>4 on an 11-point NRS) and meet the NICE diagnostic criteria for knee OA (aged 45 years or older; activity-related joint pain; no morning stiffness or morning stiffness that lasts no longer than 30 minutes), or have received a diagnosis of knee OA from a medical professional.
Exclusion criteria
People will be excluded if they have: a) health conditions that prevent safe participation in exercise (e.g., severe cardiac or lung disease); b) self-reported evidence of a separate medical condition that impairs movement or may require immediate medical intervention, such as an inflammatory condition (e.g., rheumatoid arthritis), neurological disorders (e.g., multiple sclerosis), planned knee replacement surgery during the intervention window, evidence of presence of a metastasizing cancer; or c) evidence of other conditions that may preclude participants from understanding or being able to participate in study procedures (e.g., dementia).
