At the end of the four week period, or up to 72 hours before discharge, the baseline assessment barrage will be repeated by the baseline assessor (still blinded, participants prompted not to divulge group allocation) In order to evaluate the experience of exercising out of therapy sessions, the research physiotherapist will conduct a one to one interview with some of the patient participants. They will be selected via purposive sampling, accounting for initial weakness category and previous experience of using tablet technology. Open ended questions will be used to find out how easy they found it to exercise their affected arm out of therapy time.
