Abstract
Functional Electrical Stimulation
(FES) has been adopted in the lower limb
rehabilitation where electrical currents were
applied to paralyzed muscles to avoid muscle
atrophy and to restore motor function. In this
study, we designed and fabricated a prototype of
an electrically assisted wheelchair pedaled by
the electrically stimulated lower limbs. This
design not only allowed the paralyzed lower
limbs to achieve periodic cycling exercises but
also made the rehabilitation process more
versatile and interesting. A six-bar lower limb
cycling model was developed combining a
muscle model to lay a foundation for a
theoretical study. The system was equipped with
a disk motor incorporated into the front wheel
which would provide power assistance when the
wheelchair is in a up-hill situation, or the muscle
fatigue sign is on, or the patient simply gets tired.
In this study, seat position adjustments was
designed for ergonomic reasons.
