简要总结
Stroke is the third commonest cause of death and is probably the commonest cause of severe disability. Upper limb recovery after stroke is unacceptably poor with only 50% of stroke survivors likely to regain some functional use. In many disabilities, the rehabilitation process is of long duration and clinicians face the challenge of identifying a variety of meaningful and motivating intervention tasks that may be adapted and graded to facilitate this process.. Motor learning models emphasize that self-generated voluntary actions should be used and repeated in playful and motivational settings and that the difficulties of the task have to be at an appropriate level for successful learning. Motivation to use the hemiplegic upper extremity was considered to be the most important factor in guaranteeing intense practice and was achieved through the patient's individual inner drive and motivation for play. Virtual reality-based therapy is one of the most innovative and developments in rehabilitation technology. Enhanced feedback provided by a virtual reality system has been shown to promote motor learning in normal subjects. Interaction with objects in a virtual environment (VE) through grasping and manipulation is an important feature of future virtual reality simulations. Until now, there has been limited research involving the inclusion of virtual reality gaming systems in neuro-rehabilitation for hemiplegic patients. So the purpose of this study will be evaluation of the efficacy of virtual reality technology on improving the function of the involved upper extremity in Saudi patients having stroke.

结局指标
主要结局
Change in the score of Fugl-Meyer Assessment Scale of Upper-Extremity (scale that assess the change in upper extremity motor functions)
时间窗: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between Fugl-Meyer Assessment Scale Score of Upper-Extremity at both baseline and completion of 12 weeks of intervention)
The Fugl-Meyer Assessment of Upper Extremity (FMA-UE) is a stroke-specific, performance-based impairment index. It measures the movement, coordination and reflex action of the shoulder, elbow, forearm, wrist and hand. The scale includes 33 items divided into 4 subscales: (A) shoulder/elbow, 18 items, (B) wrist, 5 items, (C) hand, 7 items, and (D) coordination/speed, 3 items. Each item is scored on an ordinal 3-point scale, where 2 points are assigned when the movement is performed fully, 1 point when performed partially, and 0 points when the movement cannot be performed. A total score of 66 indicates better sensorimotor function. Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity motor functions.
Change in the score of The Action Research Arm Test (test that assess the change in upper extremity functions)
时间窗: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between The Action Research Arm Test Score at both baseline and completion of 12 weeks of intervention)
The Action Research Arm Test (ARAT) is an evaluative measure to assess specific changes in limb function among individuals with hemiplegia. It assesses a patient's ability to handle objects differing in size, weight and shape and therefore can be considered to be an arm-specific measure of activity limitation. The ARAT consists of 19 items grouped into four subscales: grasp, grip, pinch, and gross movement. The ARAT is scored on a four-level ordinal scale (0-3): 0 = cannot perform any part of the test, 1 = performs partially, 2 = take long time to complete the test, and 3 = performs the test normally. The total score on the ARAT ranges from 0 to 57, with the lowest score indicating that no movements can be performed, and the upper score indicating normal performance. Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity motor functions.
Change in the score of The Wolf Motor Function Test (test that assess the change in upper extremity motor ability)
时间窗: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between The Wolf Motor Function Test Score at both baseline and completion of 12 weeks of intervention)
The Wolf Motor Function Test (WMFT) is designed to assess upper extremity motor abilities in patients with stroke through timed and functional tasks. The WMFT consists of 15 timed items (6 items involve timed functional tasks, and 9 items consist of analyzing movement quality when completing various tasks), in addition to 2 items (7\&14) are measures of strength. The examiner should test the less affected upper extremity followed by the most affected side. The 15 timed items are rated on a 6-point functional ability scale (0-5), score (0) means the patient is unable to use UE being tested while score (5) means the patient is able to use it and movement appears to be normal. The total score on the WMFT ranges from 0 to 75. Lower scores are indicative of lower functioning levels. Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity (UE) motor abilities.
