O treinamento de reabilitação com pedalada em cadeira de rodas em combinação com estimulação elétrica funcional (FES) pode ser eficaz para diminuir significativamente o risco de queda. O ajuste automático da velocidade do ciclismo e a realização de curvas sem paralisação têm sido desejados para aplicações práticas do treinamento com ciclismo FES móvel. Este estudo teve como objetivo desenvolver um sistema de controle em malha fechada da velocidade do ciclismo com a cadeira de rodas pedalada. Considerando o uso prático clínico sem necessidade de modificações extensas na cadeira de rodas, foi introduzido um método de medição da velocidade do ciclismo com unidades de medição de movimento inercial (IMUs) e foi projetado um controlador fuzzy para ajustar a intensidade da estimulação para regular a velocidade do ciclismo. O protótipo desenvolvido do sistema de controle FES de circuito fechado alcançou velocidade de ciclagem adequada para as diferentes velocidades alvo na maioria dos ensaios de controle com indivíduos neurologicamente intactos. Além disso, todos os testes de controle de ciclismo em baixa velocidade, incluindo inversão de marcha, conseguiram manter a velocidade alvo sem paralisação. A distância e o tempo de ciclismo aumentaram com o controle em circuito fechado de baixa velocidade de ciclismo, compensando a diminuição da velocidade de ciclismo causada pela fadiga muscular. A partir desses resultados, sugeriu-se que o sistema de controle FES difuso de malha fechada funcionasse de maneira confiável no ciclo FES móvel.

Abstract: Rehabilitation training with pedaling wheelchair in combination with functional electrical stimulation (FES) can be effective for decreasing the risk of falling significantly. Automatic adjustment of cycling speed and making a turn without standstill has been desired for practical applications of the training with mobile FES cycling. This study aimed at developing closed-loop control system of cycling speed with the pedaling wheelchair. Considering clinical practical use with no requirement of extensive modifications of the wheelchair, measurement method of cycling speed with inertial motion measurement units (IMUs) was introduced, and fuzzy controller for adjusting stimulation intensity to regulate cycling speed was designed. The developed prototype of closed-loop FES control system achieved appropriately cycling speed for the different target speeds in most of control trials with neurologically intact subjects. In addition, all the control trials of low speed cycling including U-turn achieved maintaining the target speed without standstill. Cycling distance and cycling time increased with the closed-loop control of low cycling speed compensating decreasing of cycling speed caused by muscle fatigue. From these results, the developed closed-loop fuzzy FES control system was suggested to work reliably in mobile FES cycling.
