2. Fig 1
Gait parameters defined from contact phase of vertical (Fz) ground reaction force (upper figure) and of az acceleration signals (lower). The initial parts of the signals are on an expanded scale on the right demonstrating the definitions of the rate of loading parameters. The ground reaction force of a left limb is demonstrated as a grey line in the upper left figure. Abbreviation: BW, body weight.

4. Fig 3
Linear correlations between loading parameters of vertical (Fz) ground reaction force and az and ar accelerations during walking with normal speed. (A) Fz1 max and IPAa1z; (B) maximal loading rate (LRmax) and ATRmax a1z; (C) average loading rate (LRave) and ATRave a1z; (D) maximal loading rate and ATRave a1z; (E) maximal loading rate and IPAa1z; and (F) LRmax and IPAa1r. Acceleration was measured with the SMAs attached below the knee.
