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.
