Chronic Stroke
Conditions
Brief summary
Stroke, a leading cause of disability worldwide, particularly affects upper extremity function, rendering individuals dependent on others for daily living activities and reducing their quality of life. To mitigate these effects, Action Observation Therapy (AOT), which has gained prominence in recent years, activates the mirror neuron system, triggering learning processes in the motor cortex and supporting functional recovery through the imitation of observed movements. Furthermore, telerehabilitation offers a significant advantage in facilitating access to rehabilitation services for these patients requiring long-term treatment, eliminating barriers such as transportation and cost. The absence of studies in the literature comparing the effectiveness of combining these two methods on hand skills and quality of life in individuals with chronic stroke with conventional physiotherapy makes investigating the clinical value of this approach academically unique and necessary.
Detailed description
Stroke is defined as a neurological condition caused by focal damage to the central nervous system due to vascular problems such as cerebral infarction, intracerebral or subarachnoid hemorrhage. Stroke is among the leading causes of death and disability worldwide. Functional impairment in the upper extremities is frequently observed in stroke patients, significantly limiting their grasping and releasing functions, and consequently their daily living activities (ADL) such as eating, drinking, dressing, and self-care. Due to these limitations, stroke patients become dependent to varying degrees, negatively impacting their quality of life. Scientists are conducting various studies to find effective, low-cost, and easily applicable methods that can reduce the effects of stroke, which imposes a significant economic, physical, social, and psychological burden on patients and their families, and improve recovery. Action Observation Therapy (AOT), which involves observing simple actions frequently used in ADL and then imitating those observed actions, is a rehabilitation approach applied in clinical settings in recent years to improve upper extremity function in the rehabilitation of stroke and various neurological diseases. The neural basis of AOT is the mirror neuron system, which is active not only when observing one's own movements but also when observing others' movements. Studies using Functional Magnetic Resonance Imaging have shown that mirror neuron activity increases when observing the movements of others. It is stated that observing an action and then trying to imitate it reduces interhemispheric inhibition, and as a result, it activates the primary motor cortex that causes the observed movement, facilitates the execution of the action, eliminates motor function disorders, and allows for the relearning of functions. Telerehabilitation is the remote delivery of rehabilitation services through telecommunication technology. Telerehabilitation increases the accessibility of physiotherapy interventions in situations where face-to-face rehabilitation is not possible or difficult to access. In stroke patients with a lengthy rehabilitation process, telerehabilitation offers significant advantages, including reduced difficulties in transferring the patient to the healthcare center, shorter travel time, reduced transportation costs, and lower energy costs. A literature review revealed no studies comparing the effects of AOT delivered via telerehabilitation on upper extremity function, hand skills, daily living activities, and quality of life in patients with chronic stroke compared with conventional physiotherapy.
Interventions
OTHERConventional physiotherapy
All participants will receive conventional physiotherapy, including stretching, strengthening, core mobility, balance, electrotherapy, and endurance exercises in the clinic. These traditional sessions will be administered by physiotherapists three times a week, each lasting 45 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Spasticity | Baseline | Spasticity will assessed using the Modified Ashworth Scale. As the score increases, spasticity increases. The minimum score for this scale is 1 and the maximum score is 5. |
| Stage of hemiplegia | Baseline | "Brunnstrom Hemiplegia Recovery Staging" will be used to determine the hemiplegic stage of the patients. This scale is scored between 1 and 6. As the score increases, the patient improves. |
| Motor function | Baseline, five week later (after intervention) | The "Fugl-Meyer Upper Extremity Motor Assessment Scale" will be used to evaluate upper extremity motor functions. This scale ranges from 0 to 66 points. As the score increases, motor function improves. |
| Dominant side | Baseline | The "Edinburgh Hand Preference Test" will be used to determine the dominant side used by the patient in daily life. It will be used to determine which hand the patient uses more in daily life (Score range: -100 to +100; high positive scores indicate right-handedness, high negative scores indicate left-handedness). |
| Upper extremity function | Baseline, five week later (after intervention) | Evaluation of upper extremity functions (hand-arm) and motor speed will be done with the "Nine-Hole Peg Test". It is a widely used clinical test that evaluates upper extremity function (hand and arm) and motor performance. The test consists of nine wooden sticks with a diameter of 9 millimeters (mm) and a standard wooden block with nine holes of 10 mm diameter. The patient inserts the nine sticks one by one into the nine holes as quickly as possible, placing them randomly into the holes, and then removes them one by one in the same manner. The timer is started when the first stick is inserted and stopped when the last stick is removed and released from the hand. The time taken for the patient to insert and remove the sticks is recorded. A shorter time indicates better upper extremity function. |
| Functional Independence | Baseline, five week later (after intervention) | Evaluation of upper extremity functions will be done with the "Functional Independence Scale (FIS)". The is used to assess the change and development in ADL (Applications for Daily Living) depending on the degree of disability experienced by individuals and rehabilitation programs. Consisting of a total of 18 items, the FIS is divided into two main subcategories: motor domain (FIS-motor; 13 items) and cognitive domain (FIS-cognitive; 5 items). All activities are rated on a 7-point scale ranging from 1 (requires full assistance during activities) to 7 (performs the activity completely independently). The total FIS score ranges from 18 to 126 points. A decrease in the score indicates an increase in the individual's dependence during ADL. |
| Cognitif Function | Baseline | Mini Mental Test will be used to evaluate cognitive functions. In the evaluation, 24-30 points indicate that cognitive functions are normal, 18-23 points indicate mild cognitive impairment, and 17 points and below indicate that cognitive status is severely affected. |
| Neglect | Baseline | The Catherine Bergego Scale will be used to assess the impact of unilateral neglect after stroke on activities of daily living. 1-10 indicates mild neglect, 11-20 indicates moderate neglect, and 21-30 indicates severe neglect. |
| Life Quality | Baseline, five week later (after intervention) | The Stroke Specific Quality of Life Scale will be used to assess the quality of life of individuals with stroke. The higher the total score, the better the quality of life of the individual with stroke. This scale is scored between 49-245.As the score increases, the quality of life increases. |
