Sealed opaque envelopes contained randomly generated codes for treatment allocations will be given to a member of the clinical team. Once informed consent has been provided, the envelope will be opened randomising participants into two groups: 1) A control group who will conduct conventional sit-to-stand training and 2) An experimental group who will conduct augmented STS training using the feedback system. Twenty participants will be randomly allocated to each group. Participants allocated to either group will be attached with a physical activity monitor (ActivePAL sensor,PAL Technologies Ltd, Glasgow) by the researcher onto the unaffected or dominant side of the thigh. Full instructions will be provided on its use. The monitor is small and lightweight (<15 grams) but capable of detecting and storing information on movement and position (e.g. duration of sitting, standing and the number of STS execution 24 hours aday for 28 days).Data to record from medical notes: Participants' background information (i.e. gender, age, height, weight, reasons for admission and number and type of co-morbidities) will be noted.Pre-assessments:
