A 1-DoF robot is designed and fabricated to be used for knee rehabilitation
training. The mechanism (robot) is designed to perform specific set of exercises
while the patient is sitting on a chair. The therapy process for patients has
different stages; each stage consists of specific exercises to recover the knee
to its condition before injury.
The maximum torque of healthy joint during the
extension/flexion exercise is evaluated by simulation and suitable actuator is
selected based on the results.
A prototype is then fabricated as a platform to
evaluate the design and control concepts. The experiment procedure consisting of
three stages of therapy indicates good tracking performance and safe operation of
the system. Implication for Rehabilitation A 1-DoF mechanism for knee
rehabilitation has been designed to perform three stages of therapy: passive,
active assist and active resist. The assistive and resistive torque, during
active assist and active resist stages, can be set according to the progress in
therapy. The results of this study suggest the system has the potential to result
in various benefits including reduction of physical workload of physiotherapists
and improved repeatability.
