INTRODUCTION:-

 A stroke is a clinically defined syndrome characterized by quickly emerging symptoms or indicators of focal loss of cerebral function, with no other apparent cause than vascular origin. However, the loss of function can occasionally be global (applied to patients with subarachnoid haemorrhage and deep coma). symptoms could be fatal or linger longer than 24 hours.1. The severity of the illness ranges from a full recovery in a single day to a severe handicap that requires lifelong care to death. The criteria has not changed in over 20 years, and there is no cause to change it in the near future, whether it is for epidemiological or clinical purposes. If the definition relied too much on technology—like brain imaging—epidologists wouldn’t be able to apply it .(¹⁾

The main finding, which is surprising, is that haemorrhagic strokes, not ischemic ones, accounted for most stroke cases worldwide in 2010. A third (31·5%) of the 16·9 million incident stroke events (20% in high-income countries and 37% in low- and middle-income countries) were haemorrhagic strokes, an incidence rate that is greater than previously thought. Even so, hemorrhagic stroke accounted for three-quarters (61·5%) of the 102·2 million DALYs lost globally and over half (51·7%) of the 5·9 million stroke-related deaths, while being only half as common as ischemic stroke. Compared to ischemic stroke (mean age 65·1 years [SD 0·11]), which afflicted persons at a later age (73·1 years [0·10]), hemorrhagic stroke caused a greater number of years of life lost. ⁽²⁾

The second important finding is that low-income and middle-income countries bear the majority of the burden of ischemic and hemorrhagic stroke, accounting for 63% of incident ischemic strokes and 80% of hemorrhagic strokes, 57% of ischemic stroke-related deaths and 84% of hemorrhagic stroke-related deaths, and 64% of DALYs lost as a result of ischemic stroke and 86% due to hemorrhagic stroke. ⁽²⁾

The third finding indicates that individuals under 75 years of age carry the majority of the burden of ischemic and hemorrhagic stroke, accounting for 62% of incidence ischemic strokes and 78% of hemorrhagic strokes, as well as 63% of DALYs lost as a result of ischemic stroke and 83% owing to hemorrhagic stroke. ⁽²⁾

The fourth finding shows that, between 1990 and 2010, there was a significant increase in the total number of people who had incident ischemic stroke (up 37%) and incident hemorrhagic stroke (up 47%), as well as a rise in the number of deaths from ischemic stroke (21%), hemorrhagic stroke (20%), and DALYs lost from ischemic stroke (18%) and hemorrhagic stroke (14%). The age-standardized incidence of both ischemic and hemorrhagic strokes has decreased by 13% and 19%, respectively. Stroke mortality rates have also decreased by 37% and 38%, and DALY rates for both types of strokes have decreased by 34% and 39%, respectively. Nevertheless, the absolute numbers have increased. ⁽²⁾

Fifth, there has been a twenty-year increase in the incidence of hemorrhagic stroke in low- and middle-income countries (22% increase, 95% CI 5-30), with a notable increase in cases in those under 75 years of age (19%, 5-30). As a matter of fact, compared to high-income countries, low- and middle-income countries had greater rates of hemorrhagic stroke: 40% higher incidence, 77% higher mortality, and 65% higher DALY rates. ⁽²⁾

The capacity to carry out precise, fluid, and regulated motor responses is known as coordination or coordinated movement. It is a difficult procedure that depends on a fullywhole neuromuscular system. The characteristics of coordinated motions include muscular tension, timing, distance traveled, direction, and speed. Physical therapists can access motor performance information through coordination assessments. They aid in determining the cause of motor impairments. Numerous observational coordination tests have been offered, and related research has been conducted. ⁽³⁾

The ability to integrate and analyze touch and visual information in the central nervous system to enable intentional motor movements is known as eye-hand coordination. There exist two distinct components to eye-hand coordination. Validation Reaction (an open motor skill) and (a closed motor talent). Action that the athlete controls or initiates is referred to as probation. Movement that takes place in reaction to another activity is referred to as a reaction. The ability of the visual system to synchronize the information received through the eyes to control, lead, and mentally direct the hands in the completion of a specific action, such writing by hand or catching a ball, is known as hand-eye coordination. Hand-eye coordination involves using the hands to carry out an action and the eyes to focus attention. ⁽⁴⁾

Patients who have had a stroke frequently struggle with hand-eye coordination, which impairs their finger dexterity and perception accuracy. These limitations may have a major effect on their general quality of life. In order to test upper limb impairment and coordination, a new eye-hand correlation evaluation system with improved assessment metrics is presented in this work. It correlates hand and arm movements with eye-gaze via a robotic haptic device. To quantify the displacement of upper limb joint angles, the experimental setup incorporates four inertial sensors, an eye tracker, and a haptic device. In a virtual world, the user makes different hand movement patterns as data is being simultaneously gathered from the hand, eye, and arm movements. The Pearson coefficient was used to generate the eye-hand coordination measure (EHCM), which was then associated with upper limb movements. ⁽⁵⁾

NEED FOR STUDY-

stroke is very common and is caused by a lot of factors, which include a sedentary lifestyle, hypertension, smoking, stress, and head injury.

Stroke has a lot of repercussions, which include limb weakness, dropping of the eyelid,

Deviation of the mouth, difficulty speaking, and swallowing, especially in coordination

Due to impaired coordination, it causes disturbed eye-hand co-ordination, which causes difficulty in daily life for stroke survivors.

To check the effect of an experimental protocol on stroke patients in comparison with a conventional or traditional approach (protocol).

People with stroke have impaired co-ordinatiob and reduce upper extremity motor function some studies shows conventional protocol for improving coordination but there is paucity in the literature that includr combine effect of eyehand coordination device along with coordination exercises to improve in coordination in stroke surviors so this study is initiative approach to improve coordination in stroke surviours.
