Approximately 80% of stroke patients experience upper extremity hemiplegia (UE), leading to chronic injuries such as loss of motor control, pain, and cramps
.

These have an important impact on the quality of life, because the impairment of hand and arm function restricts participation in activities of daily living

Advances in rehabilitation technology, especially robotics, virtual reality (VR) and neuromuscular electrical stimulation (NMES), have been shown to be effective in improving the UE function of stroke patients by providing such repetitive and task-oriented training

Although advances in robotics, virtual reality, and NMES technology have led to new treatment models for post-stroke UE functions, further progress is needed for these technologies to have a real impact
.

Specifically, the Personalized Upper Limb Rehabilitation (SUPER) plan in this article includes: (1) Robot activities to perform body-assisted UE stretching exercises; (2) VR activities to perform unassisted hand extension and grasping movements; and (3) NMES, to facilitate hand stretching

The goal of this article is to determine the feasibility and therapeutic effect of individualized rehabilitation programs in patients with moderate/severe chronic stroke

Stroke participants (n = 28) received a 4-week intervention (three trainings per week).
The functional integrity of the corticospinal tract was assessed using physiological electrical signals, including motor evoked potential measurements and manual muscle tests
.

Patients with low hand recovery potential (shoulder joint group; n = 18) received robotic rehabilitation intervention that focused only on elbow and shoulder movements

Stroke participants (n = 28) received a 4-week intervention (three trainings per week).

Overall view of the robotic rehabilitation system

In this study, the feasibility of individualized rehabilitation program intervention was determined, and the initial efficacy of combining robotics, VR and NMES to improve UE function in patients with chronic stroke was measured
.

It shows that the rehabilitation effect is safe and welcomed by the participants.

The results show that virtual reality, robotics, and electrical stimulation can help improve UE function in patients with moderate to severe damage caused by stroke
