Abstract
Rehabilitation is the process of treating post-stroke consequences. Impaired limbs are considered the common outcomes of stroke, which require a professional therapist to rehabilitate the impaired limbs and restore fully or partially its function. Due to the shortage in the number of therapists and other considerations, researchers have been working on developing robots that have the ability to perform the rehabilitation process. During the last two decades, different robots were invented to help in rehabilitation procedures. This paper explains the types of rehabilitation treatments and robot classifications. In addition, a few examples of well-known rehabilitation robots will be explained in terms of their efficiency and controlling mechanisms.
Highlights
Stroke is considered one of the leading causes of death; it comes in the third place after heart disease and cancer [1]
This paper focuses on after-stroke rehabilitation and upper limb rehabilitation robots
The Genetic algorithm (GA) algorithm uses the root mean square (RMS) as a controlling feature, where the best output solution “which is usually named as a chromosome” is the output that minimizes the RMS between the torque estimated by the EMG signal and the torque estimated by the model [67]
Summary
Stroke is considered one of the leading causes of death; it comes in the third place after heart disease and cancer [1]. It has been reported that up to 30% of stroke patients suffer from permanent disabilities and up to 20% require intensive rehabilitation programs [2]. Rehabilitation programs require one-on-one interactions between the therapist and the patient. Interactive rehabilitation is a time-consuming and labor-intensive for both the therapist and the patient [2]. These facts pushed researchers to invent rehabilitation robots that can be used as assistive devices for therapists. This paper focuses on after-stroke rehabilitation and upper limb rehabilitation robots. A discussion and a conclusion are given in Sections 6 and 7, respectively
