Analysis of the Effectiveness of Visual Training in Stroke Rehabilitation

The Fugl-Meyer Assessment-Upper Extremity subscale was employed to examine the motor function restoration in the upper extremity of stroke patients following interventions. The Fugl-Meyer Assessment-Upper Extremity consists of 33 items that assess motor function, with a scoring range of 0-66, The minimum score 0 represents severe impairment, and maximum score 66 represents normal motor function. Higher scores indicate better motor function.

The Action Research Arm Test is utilized to examine the functional capabilities of stroke patients upper extremities, specifically in terms of reaching, gripping, pinching, and overall movement tasks. Each item is allocated a rating score of 4 points, with the potential total values ranging from 0 to 57. The minimum score 0 represents severe impairment, and the maximum score 57 represents normal upper extremity function. Higher scores on the Action Research Arm Test indicate better functional capabilities of the upper extremities.

The BBT evaluated the manual dexterity of individuals who had suffered a stroke. During this assessment, participants are required to transfer blocks from one container to another within a one-minute time limit.

Electromyography signals are obtained in order to evaluate the electrical activity generated by muscles. Electromyography was utilized for the objective assessment of the effectiveness of immersive VR-based hand games. The objective assessment includes the evaluation of the correlation between electromyography signal features and clinical outcomes, which includes the Fugl-Meyer Assessment-Upper Extremity, Action Research Arm Test, and Box and Block Test.

The weekly movement performance was evaluated by machine learning algorithms that include k-nearest neighbors, random forest, and support vector machine classifiers on the electromyography signals of stroke patients.

The Modified Barthel Index assesses an individual's ability to perform both practical and routine tasks independently. The Modified Barthel Index consists of 10 items, each scored based on the level of assistance required or the level of autonomy demonstrated by the patient. The total score ranges from a minimum of 0 to a maximum of 20. Lower scores indicate greater dependence, with scores below 10 typically representing severe disability and scores below 15 usually indicating moderate disability. Moreover, higher scores reflect greater independence in performing daily activities.

The Stroke-Specific Quality of Life measure was used to assess the health-related quality of life of stroke survivors. The Stroke-Specific Quality of Life scale consists of 49 comprehensive items that evaluate various aspects of quality of life based on the patient's current state. The total score ranges from a minimum of 49 to a maximum of 245. Lower scores indicate poorer health-related quality of life, and higher scores indicate better health-related quality of life.
