title: Biodynamics of the ankle in spastic children--effect of chronic stretching of the calf musculature.
abstract: The biodynamics of the feet of spastic children have been studied by estimating the resonant frequency using a printed motor to supply rhythmic torques. Changes induced when the muscles have been stretched by casting for four weeks are trivial or absent. The position of the feet, however, after the procedure became more nearly normal.
