Computer generation of human gait kinematics

The paper describes a computer program that generates absolute motion variables of human gait from predetermined relative motions. Relative displacements are measured over a range of step rates during both free (self-determined step rate at different speeds) and forced (forced step rate at a constant speed) walking, converted into harmonic coefficients and stored in an array as a function of step rate. Only six variable identifiers need to be specified to compute any absolute variable or its derivatives at any desirable step rate. The paper displays some examples of measured relative motions and reconstituted absolute variables.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23673/1/0000641.pd
