The intervention group will have the same exercises as the control group plus imagined wrist exercises. The exercises will be taught to the subject by reading through the booklet with them, this ensures the advice is standardised. As the intervention is targeting part of the brain involved in the control of movement, high frequency is considered important. The imagined movement programme, is amalgamated from two previous studies and will consist of imagined wrist movement in all planes. The frequency of 15 minutes every waking hour from one study is deemed impractical and another study suggests that 15 minutes of mental practice a day preserved range of motion. Therefore approximately 10-15 minutes, four times a day has been selected as a practical compromise and mirrors routine advice.
