Abstract
The purpose of this study was to investigate the efficacy of a pre-existing comprehensive pulmonary rehabilitation (PR) program at The University of Iowa Hospitals and Clinics for patients with chronic obstructive pulmonary disease (COPD). The specific objectives were to investigate the effects of eight weeks of PR on: 1) self-selected walking velocity (SSWV); 2) total distance walked and final heart rate (HR), ratings of perceived exertion (RPE) and dyspnea index (DI) scores for a six minute walk test (6 MWT); 3) estimated peak oxygen consumption (V02 - METs) and submaximal HR, RPE, and DI versus estimated VO2 response for a treadmill symptom limited graded exercise test (SLGXT); and 4) total time, and submaximal HR, RPE, and DI scores versus time responses for a treadmill walking endurance test (ET). Five outpatients ranging in age from 64-76 years (mean = 70 ± -5.2 years) (mean weight = 75.2 ± -13.1 kg) with a primary diagnosis of emphysema (mean FEV, = 1.09 ± -0.27 L) with a variety of comorbidities volunteered as subjects. A test-retest experimental design was used to assess the pre versus post PR results of an eight week (three times per week) comprehensive education and endurance circuit exercise training program consisting of treadmill walking, Airdyne bicycling, step exercise, arm ergometry, and upper extremity resistive exercise. Paired t-tests were used for general pre-post PR mean contrasts. Repeated measures ANCOVA was used to evaluate SLGXT HR, RPE, and DI versus MET, and ET HR and RPE versus time regression response lines. Patients exhibited a 16% mean increase in SSWV (2.2 mph to 2.5 mph), a significant 22% mean increase in 6 MWT distance (1000 ft to 1224 ft), a significant 89% increase in SLGXT determined peak VO2 (2.9 METs to 5.5 METs) and a significant 97% increase in ET total walking time (10.14 min to 20.00 min). Subjective pre-post PR reportings of RPE and DI scores were significantly reduced for the SLGXT and ET tests. Results showed positive exercise training responses with decreased respiratory symptoms. Patient subjective feedback suggested enhanced functional activity tolerance and improved general quality of life. Although the subject sample size of this study was small (n = 5), the results support the efficacy of PR for moderately to severely compromised COPD patients.
