Also listed are the mean coefficients of determination R2 between the zero-moment force curve and the experimentally measured horizontal ground reaction force for medio-lateral(

\(R_{x}^{2}\)
⁠) and anterior-posterior(
\(R_{y}^{2}\)
) directions (see Eqn 11), and the mean distance between the CMP and CP points across the entire gait cycle normalized by foot length for each study participant (β%) is given
