GEE regression coefficients (β) for the effect of stride length, stride frequency and walking speed on the one hand and the ML MoS, the BW MoS and LDS expressed as λs on the other hand.

=  β1*stride length + β2*stride frequency + β3*walking speed + intercept In the model stride length, stride frequency, and walking speed are expressed as the fraction of the comfortable value. The model used is: outcome measure
*significant at the 0.05 level
