Abstract
MacKay-Lyons MJ, Makrides L. Exercise capacity early after stroke. Arch Phys Med Rehabil 2002;83:1697-702. Objective: To evaluate exercise capacity of patients with a poststroke interval of less than 1 month. Design: Prospective, cohort, observational study. Setting: Exercise testing laboratory in a tertiary care hospital. Participants: Twenty-nine patients (mean age ± standard deviation, 64.9±13.5y) with a poststroke interval of 26.0±8.8 days. Interventions: Not applicable. Main Outcome Measure: Peak exercise capacity (VO2peak) was measured by open-circuit spirometry during maximal effort treadmill walking with 15% body-weight support. Results: Mean VO2peak was 14.4±5.1mL · kg−1 · min−1 or 60%±16% of age- and sex-related normative values for sedentary healthy adults. Conclusions: Exercise capacity approximately 1 month after stroke was compromised. Further research is needed to elucidate the physiologic basis of this low capacity. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation
