Table 3.

Group means and standard deviations for joint powers of the ankle, knee and hip joint for Peripheral Arterial Disease (PAD) and control groups. The units for all values are Watts/kg.

Note:

^ap < .05, significant differences between groups (PAD-PF, Non-Affected limb vs. Control).

^bp < .05, significant differences between groups (PAD-PF, Affected limb vs. Control).

^cp < .05, significant differences between groups (PAD-P, Non-Affected limb vs. Control).

^dp < .05, significant differences between groups (PAD-P, Affected limb vs. Control).

^ep < .05, significant differences between testing conditions (PAD-PF vs. PAD-P).
