Arm Cycling in Facioscapulohumeral Dystrophy (FSHD) Patients

The investigators believe that arm cycling has the potential to be effective in maintaining or improving shoulder muscle functioning. However, there is no evidence for its safety or effectiveness in the upper extremity. The aim of the study is to establish the ability of FSHD sufferers to perform arm cycling to underpin the future design of an arm exercise trial. The study hypothesis is that the limited range of shoulder movement and muscle weakness should not impact the ability of FSHD sufferers to perform arm cycling.
