Design of a trike for paraplegic use with FES




The goal of this research is to design, build, and test new pedaling mechanisms to be incorporated into a bicycle-like devices for spinal-cord injured individuals. Many challenges arise in pedaling capability of a paraplegic or tetraplegic patient that are very different from a healthy individual. The intended tricycle users mainly employ Functional Electrical Stimulation (FES) to produce quadricep contractions, which are converted into a propelling force. Various concepts for alternative mechanisms have been produced. Pedaling force and motion simulation models were generated to evaluate the concepts. The desired pedaling mechanism must overcome dead-points encountered during the pedaling cycle while optimizing the transmission of power. Thus, the goal is to convert the modest amount of power generated by FES-stimulated legs into cycling power for a tricycle.
