Spasticity is a condition characterized by increased muscle tone and stiffness, which can lead to difficulty in movement. It often results from damage to the central nervous system, such as from conditions like cerebral palsy, multiple sclerosis, or a stroke. This increased muscle tightness can cause discomfort and limit a person's ability to perform daily activities. The severity of spasticity can vary widely among individuals. Some may experience mild stiffness, while others may have significant muscle contractions that affect their posture and mobility. Treatment options include physical therapy, medications, and sometimes surgical interventions to help manage symptoms and improve quality of life.
