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
