Robot-aided gait assessment (RAGA): existing outcome measures assessing gait score with “0” people that cannot yet walk, regardless of the underlying residual function (e.g. WISCI II, 10MWT). Moreover, many assessments are categorical (e.g. WISCI II). The long-term goal of this project is to develop an assessment of walking (Robot-aided Gait Assessment—RAGA) which can provide an objective, continuous score suitable to monitor the patient’s walking ability in all stages of rehabilitation. The Y axis shows a generic “outcome measure” value. The X axis represents patient’s walking ability, divided roughly in non-ambulatory, ambulatory with assistance and walking independently.
