Peak dynamic force in human gait



Peak dynamic force in human gait



Journal of Biomechanics 14(12): 817-822



Studies were made of the forces generated at heel stroke in human gait using force plates having high resonant frequencies (capable of picking up high frequency components in the contact force) and a force transducer inserted into the heel of the shoe of the subjects. The output traces were analyzed for the existence of high frequency impulse loads during a normal walking cycle. The effect of the compliance of the foot and floor was studied with the force transducers. Results showed that during normal human gait the lower limb is subjected to a high frequency impulsive load at heel strike. The severity of this impulse varied with the individual, the velocity and angle with which the limb approached the ground and the compliance of the 2 materials coming in contact at heel strike. The magnitude of this peak force varied from 0.5-1.25 times body wt and its frequency components from 10-75 Hz.
