Participants in both groups will be asked to carry out the following baseline measurements by the researcher: 1)Timed performance of up to five repetitions of the sit to stand movement (FTSTST), if able; 2) Abbreviated Mental Test -4 with a inclusion score of 4 or higher (AMT-4); 3) Tinetti Gait and Balance Assessment (TGBA); 4) Elderly Mobility Scale Test (EMST). These assessments are already being used by the clinical team. Training with the system:The rehabilitation staff will supervise all training sessions as per normal practice. The researcher will provide technical support for all the sessions. The participant will be asked to sit on an adjustable chair with armrests. The height of the chair to be adjusted by the researcher for individual needs. A loose vest with a pouch pocket fitted near the chest region will be worn by the participant. Help will be provided by the researcher if needed. An inertial sensor (Spatial 3/3/3, Phidgets Inc, Calgary, Alberta, Canada) will be placed into the pocket and connected by a USB (Universal Serial Bus) cable to a laptop computer. The participant will then be asked to place both feet on a portable balance plate (BP5046, Bertec Inc, Columbus, OH, USA), which is also attached to the laptop via the USB. The system provides a virtual reality environment that simulates user getting on and off a bus seat. The participant can observe their real-time movement as an avatar on a computerised image (projected on a wall by a projector). Real-time feedback on performance (balance, strength and/or coordination), verbally and visually, will be provided throughout training. The game can be personalised to suit different needs based on the participant's real-time performance. Training should be two to three times a week based on advice on current practice. During the study, the researcher will check with the ward staff that the activity monitor (ActivePAL) is still attached to the participant's thigh and that they are free of skin irritation. The researcher will also change the monitor after seven days so that the skin can be fully inspected and cleaned if necessary. After the study, the monitor will be completely removed by the researcher. The captured anonymised physical activity data will be downloaded to an encrypted folder on a computer and used exclusively for this study. It will then be transferred to a secured computer at the University of Strathclyde for safe storage. Post-assessment: The researcher will carry out a repeat of the baseline measurements at the end of the study.
