triceps surae limp

triceps surae limp,

an abnormal action in the walking or gait cycle, associated with a deficiency in the elevating and propulsive factors on the affected side of the body, especially a deficiency of the triceps surae. Such a deficiency prevents the triceps surae from raising the pelvis and carrying it forward during the walking cycle. The pelvis consequently sags below its normal level and lags behind in the walking movement.
