From: Continuous relative phases of walking with an articulated passive ankle–foot prosthesis in individuals with a unilateral transfemoral and transtibial amputation: an explorative case–control study

Fig. 9

Comparison of continuous relative phases hip–knee and knee–ankle at self-selected walking speed between current prosthesis and novel prosthesis (Talaris Demonstrator) in individuals with a transtibial amputation (TTA). The continuous relative phases of the first and second row are those of the amputated limb (AMP) and the ones on the third and fourth row are those of the non-amputated limb (NAMP). The continuous relative hip–knee phases are displayed on rows one and three, and the continuous relative knee–ankle phases are presented on rows two and four. The continuous relative phases in the first column represent the mean (± SD) continuous relative phase across all gait cycles. The gait cycles are defined based on the hip flexion peak angles. The second column presents the results of the non-parametric mapping (non-parametric paired t-tests) between current prosthesis and Talaris Demonstrator. Red horizontal dashed lines depict the critical t-values
