The participants in the intervention group will have access to the tablet they are using for the duration of the study, labelled and kept in their private bedside locker. Ward staff will be prompted to ensure that during the day if a patient wishes to do their exercises they are 'set up' to do so, either by ensuring exercise sheets are to hand, or the tablet is within reach, and if necessary switched on and opened, with prompts how to start the video (as the technology may be unfamiliar to the patients.) Ward staff will also ensure the tablets are regularly charged.
