✦ Synopsis

The therapeutic skateboard in a case study, utilising electromyography (EMG) in the analysis of an assistive activity, is presented. The EMG levels of eight shoulder muscles during horizontal adduction and abduction were studied. Three conditions were analysed: the arm supported by a therapeutic skate, a five-pound weight belt on the supported arm and the non-assistive condition where the arm was unsupported. It was found that:

1 The therapeutic skate activity demanded little movement (3.8-48%) from the shoulder muscles and is suitable for early mobilisation. 2 The skateboard assists primarily the stabilisers in both horizontal abduction and adduction. 3 Addition of weights was a gentle upgrading activity creating a small increase in the eight muscles being monitored.
