The effects of physical exercise on 8 stage II peripheral vascular disease (PVD) patients were observed after a six-month training program. Doppler velocimetry (including the treadmill test), strain gauge plethysmography, and transcutaneous oxygen pressure were used to quantify the results, which were compared with those obtained in a control group of another 8 stage II PVD patients, under placebo therapy for six months. The results show physical exercise increased the walking capacity, both the pain-free walking time and the maximum walking time. No significant difference was observed in the other parameters studied, in either the exercise patients or the control group.
