External characteristics.
Fig 4.
Group ensemble mean (± SD gray shaded areas) joint kinematic and unilateral kinetic time series data.
Column 1 –ankle joint, column 2 –knee joint, column 3 –hip joint, and column 4 –pelvic-trunk joint. Row 1 –joint angles, row 2 –joint angular velocities, row 3 –joint moments, row 4 –joint powers.
Fig 5.
Ensemble group mean (± SD gray shaded areas) joint moment time series data for the pelvic-trunk, bilateral hip and bilateral knee joints.
Shaded bars represent the SnPM{t} output statistic for each comparison. Intensity of shaded areas indicate the extent to which the critical threshold (t*) was exceeded during the movement phase with a p-value given for each supra-threshold cluster superimposed on top.
