Stroke is one of the leading causes of acquired disability among adults, as it may result in motor weakness and impaired upper-limb control, affecting patients’ ability to perform activities of daily living and limiting their independence and quality of life. Mirror therapy is a non-invasive rehabilitation intervention used in physiotherapy and neurological rehabilitation. It relies on visual feedback by placing a mirror along the body’s midline, concealing the affected limb while allowing the patient to observe the reflection of movements performed by the unaffected limb as if they were produced by the affected limb. This technique is believed to support motor attention, motor learning, and the activation of neural networks associated with action observation and motor imagery, potentially contributing to improved motor performance in some patients following a stroke. The implementation of mirror therapy begins with an assessment of the patient’s motor and functional status, including range of motion, muscle strength, muscle tone, sensation, pain, and visual and cognitive abilities. The patient then sits in a stable position in front of the mirror and is instructed to focus on the reflection of the unaffected limb while performing a series of simple movements, such as opening and closing the hand, flexing and extending the fingers, moving the wrist, rotating the forearm, and flexing and extending the elbow. The exercises may gradually progress to functional tasks appropriate to the patient’s abilities. The duration and frequency of therapy sessions should be determined according to the patient’s condition and response to treatment, while mirror therapy should be integrated with functional training and conventional physiotherapy to achieve the best possible outcomes. Systematic reviews and meta-analyses have examined the effectiveness of mirror therapy in improving upper-limb motor function and the ability to perform activities of daily living among stroke survivors. Available evidence suggests that improvements may be achieved in certain motor and functional outcomes, particularly when mirror therapy is used as an adjunct to a comprehensive rehabilitation program. Changes can be assessed using standardized outcome measures, such as the Fugl-Meyer Assessment for upper-extremity motor function, the Action Research Arm Test (ARAT) for evaluating arm and hand performance in functional activities, the Box and Block Test for measuring manual dexterity, and measures of activities of daily living and functional independence. However, outcomes vary according to the stage of stroke recovery, severity of motor impairment, cognitive and visual abilities, adherence to training, and the nature of the rehabilitation program. Furthermore, improvements in motor assessment scores do not necessarily indicate the complete restoration of independence in daily activities. Despite its simplicity, low cost, and applicability in various rehabilitation settings, mirror therapy should be administered under the supervision of a qualified physiotherapist. A safe positioning setup should be maintained, while pain, fatigue, and visual or psychological discomfort should be monitored. Exercises should be adjusted according to the patient’s response. Further high-quality clinical studies are needed to determine the optimal therapeutic dosage, identify the patient populations most likely to benefit, and establish the long-term sustainability of treatment outcomes. Accordingly, mirror therapy can be considered a promising adjunctive approach in upper-limb rehabilitation following stroke, provided that it is integrated into an individualized treatment plan incorporating conventional motor and functional training. Progress should be monitored using standardized scientific assessment tools to ensure that treatment is directed toward improving functional ability, independence, and quality of life.
