The purpose of the present study is to determine the utility and effectiveness of combined inspiratory (IMT) and expiratory muscle training (EMT) in improving ventilatory function in people who are disabled by long-term stroke (greater than 8 months following onset) with hemiparesis or hemiplegia. xx subjects will be randomized into 2 parallel groups in which the experimental group will undergo combined IMT and high-resistance EMT and the comparison group will undergo IMT with low- resistance EMT. Both training techniques involve breathing through a tube with known amounts of resistance. Subjects will perform the breathing maneuvers for 10 repetitions, twice daily, 5 days per week for 4 weeks, in the home environment. Adherence will be monitored by reminder telephone calls at least weekly. Outcomes will be assessed using maximum inspiratory and expiratory pressures and standard pulmonary function testing.
