Abstract

Peripheral arterial disease (PAD) and chronic obstructive pulmonary disease (COPD) are both characterized by dysfunctions that result in limited oxygen reaching the musculature. However, the dysfunctional characteristics are different between the two diseases. The purpose of the study was to compare the gait alterations in individuals with PAD with those individuals with COPD. It was hypothesized that both PAD and COPD patients would express differences in gait compared to healthy individuals and that COPD patients would have similar gait alterations as PAD patients. Three groups of subjects were included: 1) 25 healthy elderly control subjects; 2) 25 patients with PAD; 3) 16 patients with COPD. Participants were instructed to walk along a 10-meter walkway at their self- selected pace. Peak ground reaction forces and lower extremity ankle, knee, and hip joint muscular moments and powers in the sagittal plane of motion were measured. A one-way ANOVA was used to analyze differences between group and ground reaction forces and joint moments and powers, with a significance level set a p = 0.05. No significant differences were observed between COPD and healthy controls. Significant differences in gait mechanics occurred between PAD patients and healthy controls, as well as between PAD patients and COPD patients. These results indicate that despite both presentations of problems with oxygen delivery to tissues, the different disease mechanisms associated with PAD and COPD do not have similar biomechanical alterations under baseline conditions.
