The exercise session will then commence with a five minute warmup consisting of whole arm movements using equipment such as pedals and cylinders to facilitate activity. The patient will then be asked to perform a range of practical tasks using their weak arm e.g.turning cards, moving objects of various shapes and sizes, opening and closing bottles and bilateral activities such as lifting objects with both hands. The exercise regime will aim to incorporate 300- 400 such arm movements and will take approximately one hour.
