The knee MOvement, Balance and stabILITY study (MOBILITY)
  • What to Expect

    What will happen on the day?

    All sessions take place at the University of Exeter’s vSimulator facility, Exeter Science Park, EX5 2FN. Sessions last 1–2 hours. Support with parking and travel is provided.

    1. Arrival & preparation

    Tour the facility, confirm your details, have height, weight and knee movement measured. Reflective markers and optional sensors are attached to your skin and clothing.

    2. Familiarisation

    Walk on the platform for 20 seconds — first still, then gently vibrating. You are never alone and can stop at any time.

    3. Movement tasks

    Everyday activities: standing, walking, stepping up and down, sitting to standing. Each repeated up to 5 times with rest breaks. The platform may gently vibrate during some tasks.

    4. Virtual reality

    Using a VR headset, complete activities such as walking through a train carriage or around obstacles. You can opt out at any time.

    5. Follow-up

    Healthy volunteers attend once only. OA participants return 6–12 months after surgery for a repeat session, plus a short questionnaire at 12 months.
