1. STROKE - OVERVIEW Stroke is one of the most distressing experiences that can happen to anyone. A stroke is caused by a stoppage of blood supply to half of the brain. The term “stroke” comes from the fact that it always occurs without warning, “hitting” the person out of the blue. Worldwide, every year, 2 out of 1,000 people suffer a stroke. Five out of six strokes occur in people over sixty. It is rarely clear why a person should have had a stroke. Contrary to popular belief, stress, whether future or following a sudden event, is not in itself a cause of stroke. The most common factors are aging, and other factors include high blood pressure (hypertension), smoking, being overweight, too much sugar in the blood (diabetes), and too much cholesterol in the blood. Strokes occur when blood flow to the brain is impaired and brain tissue is broken. There are 2 main varieties of stroke: ischemic and traumatic. The severity of damage to brain tissue depends on several factors, including age, the area of ​​the brain affected, and other medical conditions. If the hand and arm do not receive real-time medical help during the stroke, it will reduce muscle power and management, leading to a claw appearance and loss of performance. The patient's daily activities will be significantly affected. Paralysis is the most common type of stroke dysfunction on the upper extremities, particularly the hand and forearm, which could limit the variety of movements and disable activities of daily living. Intensive rehabilitation medical help, such as physiotherapists, activity therapists, is distributed; However, it is limited due to the medium of the paper. The metric size of the fingers somewhat resembles that of the fingers of the human hand. The Gifu Hand Ⅱ includes a much higher number of sensors and higher response than any previously developed robot hand, and can move faster than the human hand. We tend to think that the Gifu Ⅱ hand is useful as a research tool for dexterous manipulation of robots using every force and touch sensing.A. Other Gloves or Exercise Devices: There are also other types of devices called hand exercise machines. These devices are applied to a stroke patient with minor injury or non-stroke humans with the goal of maintaining flexibility and power. The overall conclusion is that the use of advanced input devices and virtual environments can be successfully used to augment motor rehabilitation for post-stroke patients..
