According to the National Institutes of Health, muscle tone plays a crucial role in maintaining posture and regulating movement. The medical term for muscle tone, also known as residual muscle tension or the continuous, passive partial contraction of muscles, is **tonus**.

Did you know that rigidity, a form of increased muscle tone, is often a key symptom in conditions like Parkinson's disease? Understanding **what are two types of rigidity**—lead-pipe and cogwheel—is crucial for distinguishing their clinical presentation and potential underlying causes.

Medically, tone refers to the passive resistance a muscle has to stretch, which helps maintain posture and prepares for movement. This is a crucial concept for understanding many neurological and musculoskeletal conditions, going far beyond the superficial definition of physical fitness.
