With the creation of working prototypes, the MUJO devices were installed at Imperial College Healthcare NHS Trust’s Charing Cross Hospital, under the supervision of Professor Alison McGregor, where initial EMG and biomechanical modelling tests were conducted on the MUJO devices for its ability to better target specific muscle groups and train biarticular muscles over their full range.
Further tests were conducted as part of a PhD study by physiotherapist Dean Payne of Optimum Healthcare Solutions, advisor to the FA on hamstring injuries in football, on the effect of training on a MUJO hamstring machine as a way to improve hamstring torque curves.
A pre-production version of the External Shoulder device was then launched at the British Elbow and Shoulder Society annual meeting in Leicester in June 2013 where it gained positive feedback and recognition from orthopaedic surgeons and physiotherapists.
Simon Moyes, Consultant Orthopaedic Surgeon, said “What a tremendous innovation. The possibilities that this technology offers as a rehabilitation aid are significant. A single MuUJO device that allows users to perform shoulder rotation exercises over the full range of shoulder abduction movement would be a welcome addition to any post-surgery rehabilitation programme.”
Test results have provided early validation of the benefits that MUJO equipment can offer. Its unique multiple joint training system holds the potential to decrease rehabilitation time, following an injury or surgery, as well as reducing the risk of future injuries and has received numerous plaudits.
