The condition associated with high muscle tone is hypertonia. This term refers to an excessive level of muscle tension, which results in stiffness and reduced flexibility. Individuals exhibiting hypertonia may find it difficult to move their limbs due to the increased muscle stiffness, which can impact their range of motion and overall mobility.

In contrast, hypotonia describes low muscle tone, where muscles are loose and lack sufficient tension. Normotonia indicates a normal level of muscle tone, while atonia refers to a complete absence of muscle tone. Understanding the distinctions between these terms is crucial in the field of physical therapy, as it helps practitioners develop appropriate treatment plans based on the muscle tone exhibited by their patients. Hypertonia is often seen in conditions like cerebral palsy or following a neurological incident, highlighting its clinical significance.
