“…Previous work assumed that elastic elements could positively affect cycling based on the simulations of just a few sets of spring parameters [15]. In this work, the detailed FES cycling simulation environment allowed further investigation of passive knee orthoses parameters, in which we found that the spring parameters τ max and θ s may positively influence cadence.…”

“…Based on the consistency of the results from Section III-A, we built a pair of passive knee orthoses to test this effect during FES cycling exercises performed by a volunteer with SCI. Past works have previously modeled and implemented similar concepts for cycling [13], [15]- [17], yet, this is the first time that an individual cycled with passive knee orthoses using FES. While using the passive element, the cadence increased in both days of training (Tables II and III).…”

Functional Electrical Stimulation (FES) may be used in rehabilitation and assistance of people with Spinal Cord Injury (SCI). One significant application is facilitating physical exercise, mainly when combining FES with mechanical platforms, such as tricycles. However, there are still technical challenges in FES cycling protocols, such as improving control and improving cycling performance. Here we show how passive elements in knee orthoses during FES cycling could increase the average cadence, taking advantage of the cycling movement. Our approach is twofold. First, we simulated the forward dynamics of a detailed musculoskeletal model with passive elements over the knees. Simulations showed that specific spring stiffness ranges increased the crankset speed during cycling by more than 50%. Using parameters found in simulations, we built a pair of passive orthoses and performed experiments with one individual with SCI. During two days, the volunteer cycled with similar stimulation magnitude with and without the passive elements. We observed that the average crankset speed was higher by more than 10% when the springs were attached to the passive orthoses. These results show the potential of using passive elements to increase cycling speed for FES cycling with similar or even lower stimulation magnitude, leading to longer exercise duration.
