The patients in the intervention group will have their next therapy session in the normal manner, but during or at the end of the session,(whichever is most appropriate) the exercises prescribed by the therapist will be filmed onto a tablet. It will consist of the therapist performing the exercise three times to allow the participant to get the idea of the correct movement, and then the participant performing the action three times with the therapist giving verbal prompts to correct the movement.For the intervention group the therapist will be asked to film any upper limb exercises prescribed onto an i-pad, which will provided (one for each patient). Filming will be from two to three feet away, and from whatever angle the physiotherapist feels is most appropriate. The video need not include all of the patient or physiotherapist demonstrator, but should include as much of their body as the therapist feels is needed for guidance.
