About

Functional impairment in the upper extremities is one of the most common sequelae in stroke patients. It significantly limits the patients' grasping-releasing functions and, consequently, their activities of daily living (ADL), such as eating - drinking, dressing, and self-care. Action Observation Training (AOT), performed by observing simple actions frequently used in ADL and then imitating the observed actions, reduces interhemispheric inhibition and allows the elimination of impairments in upper extremity motor function and relearning of functions in chronic stroke patients. This study aims to investigate the effects of telerehabilitation and face-to-face AOT application on upper extremity functions, activities of daily living, and quality of life in chronic stroke patients and to question whether there are differences between the short- and long-term effects of these two AOT applications.

Full description

Stroke is defined as a neurological picture caused by focal damage to the central nervous system due to vascular problems such as cerebral infarction or intracerebral or subarachnoid hemorrhage.

Functional impairment in the upper extremities is one of the most common sequelae in stroke patients. It significantly limits the patients' grasping-releasing functions and, consequently, their activities of daily living (ADL), such as eating - drinking, dressing, and self-care.

Action Observation Therapy (AOT), which is performed by observing simple actions frequently used in ADL and then imitating the observed actions, is a rehabilitation approach used in recent years to improve upper limb functions in the rehabilitation of stroke and various neurological diseases. It is stated that AOT reduces interhemispheric inhibition and allows the elimination of impairments in motor function and relearning of functions.

Telerehabilitation is the remote delivery of rehabilitation services through telecommunication technology. Telerehabilitation provides important advantages, such as difficulty transferring the patient to the health center, where the rehabilitation process takes a long time, travel time, and travel costs in stroke patients.

In the literature review, no study was found comparing the effect of the AOT with the telerehabilitation method and face-to-face application on the patient's upper extremity functions, activities of daily living, and quality of life in the rehabilitation of patients with chronic stroke. In addition, to our knowledge, there is no study examining the long-term effects of AOT, which has been the subject of a limited number of studies.
