BACKGROUND Stroke survivors can exhibit abnormally elevated oxygen consumption during walking. Therapeutic interventions can improve gait deficits and oxygen consumption. A practical measure of oxygen cost is not available. This study tested the usefulness of an indirect index of oxygen cost, the Physiological Cost Index, and the ability of this index to discriminate between healthy adults and stroke survivors. METHODS The authors studied 17 subjects with stroke and 10 healthy control… CONTINUE READING
