Hypertonia

Hypertonia, also known as spasticity, is a condition in which a person's muscles become abnormally tight and stiff. It is a neurological disorder that is caused by damage to the central nervous system, most commonly in the form of an injury or stroke. This damage can interfere with the ability of the nerves to send signals to the muscles, causing them to become overly contracted. This can cause pain, difficulty in movement, and impair a person's ability to perform normal tasks. In some cases, it can also limit a person's range of motion and cause difficulty in speaking or walking. Treatment for hypertonia can include physical therapy, occupational therapy, medications, and surgery.
