Personalized Robotic Platform Rehabilitates Disorganized Gait

An advanced gait rehabilitation system uses enhanced learning intelligence technology (ELITE) to provide optimal neuromuscular re-education and brain retraining.

The Motorika (Mount Laurel, NJ, USA) Optimal-G Pro system integrates clinical principles of gait rehabilitation and motor learning with expertise in robotic technology to restore natural physiological gait patterns in both adults and pediatric patients following neurological trauma or orthopedic injury. The system provides real-time video biofeedback through front and side cameras that offer superior visualization in order to reinforce proper gait biomechanics. ELITE proactively adjusts the patient's treatment plan, based on objective clinical data and their individual progress.

Neuromuscular re-education and brain retraining are facilitated by intensive and repetitive reciprocal motion, recovering normal gait patterns and improves ambulatory capabilities, balance, stability, and posture. By continuously analyzing functional abilities, therapists can provide recommendations and correct adjustments based on treatment parameters, enabling improved decision-making, progressing therapy programs, and enhancing patient care.

The Optimal-G Pro system is designed to allow for natural gait kinematic movements of the hip, knee, and ankle during walking by helping to provide three-dimensional (3D) freedom of movement of the pelvis, including lateral shift, rotation and up/down vectors. Optimal weight bearing and pressure distribution are provided by shifting load from the robotic support to the patient’s lower limbs, using an ergonomically designed harness and foot-lifters. In addition, the system provides muscle resistance measurement, passive, active, and active-assist modes of therapy, 18 physiological gait profiles, interactive games, and virtual reality.

“Robot rehabilitation solutions enable therapists to enhance traditional treatments. For example, they can be easily used under the supervision of one therapist, providing intensive, task-oriented gait training, as part of a set of rehabilitation tools that additionally include other non-robotic approaches,” said Arik Avni, co-CEO of Motorika. “Thanks to ELITE, the Optimal-G Pro enables rehabilitation professionals, for the first time, to offer a proactive motor learning technology that personalizes patient therapy and ultimately accelerates recovery.”

Human gait is defined as bipedal, biphasic forward propulsion of the center of gravity of the human body, in which there are alternate sinuous movements of different segments of the body with least expenditure of energy. Different gait patterns are characterized by differences in limb-movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in the contact with the surface.
