Hypertonia is a condition of abnormally increased muscle tone that causes stiffness and reduced mobility. It can manifest as spasticity or rigidity and is often linked to neurological disorders like cerebral palsy or stroke. Hypertonia significantly affects a person's movement and daily activities. Treatment typically involves physical therapy, muscle-relaxing medications, and sometimes surgery to manage symptoms and improve quality of life. This condition requires ongoing management to maintain function and comfort for those affected.
