The clinical applications and benefits of the use of a Robotic Exoskeleton for Rehabilitation (RER) in the elbow and hand are described because a RER is a high-quality alternative capable of restoring compromised functions and neurorehabilitation at the same time in post-stroke patients. Passive rehabilitation (PR) is usually applied in the early stages of post-stroke recovery. The responsibility of assisting physical medicine and rehabilitation (PM&R) doctors and the patient with passive exercises is a robotic system (RS); while active rehabilitation (AR) is applied regularly in late stages, it is like PR and its implications but requires the strength and support of the person to perform the exercises voluntarily. The objective of the present study is to collect, synthesize, and report relevant scientific studies related to the implementation of exoskeleton systems for elbow-hand rehabi...
