The participants will be matched according to the severity of their weakness, then randomly allocated to either a treatment as usual group, or an intervention group. Those in the intervention group will have their exercises for their arm and hand recorded onto a tablet during their normal therapy session. They will then be lent the tablet for the duration of the trial, so they can have a visual guide to help them throughout the trial period. Ward staff will be shown how to use the tablet to help any participants who struggle with the technology.
