The degree of activation or tension in skeletal (striated) muscle. Sometimes referred to active muscle power, it is the product of force and velocity generated by a muscle (the muscle model of Archibald V. Hill (1886-1977, also referred to Hill’s equation for muscle tension-velocitycurve essential addresses this relationship). Also referred to as residual muscle tension, which encapsulates the resistance of muscles to passive stretch during a resting state, and thus is called passive muscle tone. Regardless of this distinction, muscle tone facilitates postural control and reduces during REM sleep. Preterm infants tend to display reduced muscle tone and power, a sign that can be indicative of the risk of acquiring one or other form of cerebral palsy.
