Spasticity is a condition characterized by abnormal muscle tightness due to prolonged contraction. It often results from damage to the nervous system, such as from a stroke, multiple sclerosis, or cerebral palsy. This increased muscle tone can lead to stiffness and difficulty in movement, affecting daily activities. The severity of spasticity can vary widely among individuals. In some cases, it may cause mild discomfort, while in others, it can significantly impair mobility and coordination. Treatment options include physical therapy, medications, and sometimes surgical interventions to help manage symptoms and improve quality of life.
