1. A mechanical multi-axis robotic device (10) for re-educating and/or training one or more lower limbs of a subject having an impairment of the central nervous system, comprising:
- at least two powered lower limb structures; and
one or more support structures or plates;
wherein the two powered lower limb structures are secured to the one or more support structures or plated using bolts attached to a linear actuator.

Abstract
The present invention describes a Smart Gait Rehabilitation System (SGRS). The present invention is capable of performing a quantitative analysis of human movements based on the simultaneous measurement of within-subject stride-to-stride changes in gait using accelerometers, gyroscopes, goniometers, and electromyography (EMG). The system described in the present invention is based on step-training that incorporates sensory feedback, provide feedback about kinematics and torques, and proceeds at walking speeds typical of overground ambulation.

9. A system for a priori prediction of the outcome of a physical therapy regimen or recovery in a patient following an impairment of the central nervous system, comprising the steps of:
-
identifying a patient having an impairment of the central nervous system; attaching a mechanical multi-axis robotic device to the patient (10);
wherein the multi-axis robotic device comprises two or more powered lower limb structures connected via one or more support structures or plates, an imbedded knowledge-based control system and an intelligent sensing and a data acquisition and control system connected to one or more sensors;measuring within-subject stride-to-stride changes using the one or more sensors; analyzing the movements quantitatively based on the measurements of the within-subject stride-to-stride changes; and predicting the outcome of a physical therapy regimen or recovery in the patient based on the quantitative results of the measurements of the within-subject stride-to-stride changes. - View Dependent Claims (10, 11, 12, 13)
