“…), time from midstance valley to toe-off (𝑡 (( ), the impulse of loading response and midstance (𝐼 ) ), the impulse of terminal stance and pre-swing (𝐼 * ), and the total impulse of the vertical component 𝑇𝐼 / = (𝐼 ) + 𝐼 * ). Finally, the loading rate (𝐿𝑅), unloading rate (𝑈𝑅), and the braking (𝐵𝐼 / ) and propulsion impulse (𝑃𝐼 / ) were calculated according to [20,21]. The symmetry of the ground reaction force between lower limbs (Eq.…”
