Hypertonicity refers to which condition in muscles?

Hypertonicity refers to a condition where there is excessive muscle tone, resulting in muscles being abnormally tense and exhibiting increased resistance to passive movement. This state can impede normal muscle function and joint mobility, often seen in certain neurological conditions or following trauma.

Maintaining a balance in muscle tone is crucial for effective movement and coordination. When muscles are hypertonic, they can lead to stiffness and limit a person's range of motion, impacting day-to-day activities. This condition can also affect movement patterns and may require specific therapeutic interventions to help manage the effects of high muscle tone effectively. Understanding hypertonicity is essential for occupational therapy practice, as it directly influences treatment planning and goal setting for clients with such conditions.
