Preliminary study of exercise capacity in post-acute stroke survivors.
The purpose of this study was to evaluate the feasibility and exercise capacity of cycle ergometry exercise testing and exercise performance in patients with post-acute stroke. Nineteen male patients (mean age, 62.7 +/- 9.2 years) with a post stroke interval of 9.9 +/- 2.0 days underwent symptom- limited cardiopulmonary exercise testing. Peak exercise capacity was measured by open-circuit spirometry during standard upright ergometer cycling. The mean peak oxygen uptake was 11.8 mL/kg/min, peak heart rate with age-predicted maximal heart rate was 67.9 +/- 3.4%, and peak oxygen pulse was 7.5 mL/beat. The anaerobic threshold was achieved with a mean peak oxygen uptake of 73.4%. Mean peak minute ventilation was 42.1 L/min, and ventilatory reserve was 48.1 +/- 16.8%. Our findings confirm that cycle ergometry exercise testing is feasible and exercise capacity is compromised in post-acute stroke survivors within 2 weeks after stroke. Respiratory impairments do not appear to contribute to the reduced exercise capacity post stroke.
