Fig 1.
a) Frontal plane knee fast walking kinematic waveforms for control (solid black line) and PFP (dotted red line) individuals. Power spectrums for the (b) control and (c) PFP individuals. The top three amplitudes for the power spectra are denoted and represent the three signals that were used for analysis.
Fig 2.
Comparison of the group curves for sagittal, frontal and transverse plane knee fast walking kinematics for the control and PFP individuals.
The solid line represents the mean kinematic waveform and the shaded region is the standard deviation. The control right (a) and left limbs (b), are in the top row and the PFP non-injured (c) and injured (d) limbs are in the bottom row.
