Spasticity is a condition that can manifest congenitally or later in life in children, and it is also observed in adults. Its diagnosis relies on a comprehensive neurological evaluation. This process involves a holistic assessment of the patient's history, a detailed physical examination, and findings from nervous system imaging methods when necessary. During the physical examination performed by a specialist physician, important parameters such as the patient's ability to sit, stand, walk, their posture, deep tendon reflexes, and muscle tone (tension) are carefully evaluated.
