Randomized Controlled Trial Clinical TrialEffects of home versus supervised exercise for patients with intermittent claudication.
This study was performed to test the efficacy of a supervised, hospital-based exercise program compared with a home-based exercise program involving minimal supervision, for both walking ability and quality of life measures in patients with exercise-limiting intermittent leg claudication. ⋯ A structured exercise program was more effective in improving the ICD over a 24-week period than a less formal, home-based program. However, if patients are screened properly and receive adequate instruction, a home-based program can be a safe, low-cost alternative providing similar long-term (24 weeks) exercise benefits in ACD.

Randomized Controlled Trial Clinical TrialProportional assist ventilation may improve exercise performance in severe chronic obstructive pulmonary disease.
Exercise tolerance is impaired in chronic obstructive pulmonary disease (COPD), in part because of a reduction in ventilatory capacity and excessive dyspnea experienced. The authors reasoned that proportional assist ventilation (PAV), a ventilator mode in which the level of support varies proportionately with patient effort, could be used during exercise to assist ventilation. The purpose of this study was to evaluate the efficacy of PAV to improve exercise endurance and related physiologic parameters in COPD. ⋯ Proportional assist ventilation can improve performance during constant workrate exercise in severe COPD.
