What are the causes of hypertonia and how do they contribute to the development of this condition?
Hypertonia is caused by damage to the central nervous system, such as stroke, traumatic brain injury, or cerebral palsy. This damage disrupts the communication between the brain and muscles, leading to increased muscle tone and stiffness. This contributes to the development of hypertonia by causing muscles to contract excessively, making movement difficult and affecting posture and coordination.
