This lecture introduces the MotionMaker device for lower limb rehabilitation, combining mobilization and electrostimulation therapy. It explains the interaction between the device and the user, the spinal cord functions, and the closed-loop muscle electrostimulation. The presentation covers the proof of concept with knee orthosis, the parameters of the electrostimulation controller, and the progress of voluntary and electrically induced forces. It also discusses the importance of parallel kinematics and presents upcoming products like the Lambda Health System. The lecture concludes with examples of other rehabilitation technologies like Lokomat, Reo Ambulator, and Kineassist, emphasizing the closed-loop functional electrical stimulation for gait training in paraplegic patients.
