Randomized Controlled Trial Clinical TrialA pilot exercise intervention to improve lower extremity functioning in peripheral arterial disease unaccompanied by intermittent claudication.
A pilot study was conducted to test the feasibility of supervised treadmill exercise training to improve functioning in study participants with peripheral arterial disease who did not have classical symptoms of intermittent claudication. ⋯ This pilot study demonstrated that a supervised treadmill walking program may be feasible and may improve functioning for individuals with peripheral arterial disease who do not have classical symptoms of intermittent claudication. Further study is needed with a larger sample to identify optimal exercise methods that improve lower extremity functioning in men and women with peripheral arterial disease who do not have intermittent claudication.

Multicenter Study Comparative StudyEffects of pulmonary rehabilitation on dyspnea, quality of life, and healthcare costs in California.
This study evaluated pulmonary rehabilitation as practiced in the general California medical community to determine its effectiveness in improving dyspnea and health-related quality of life and reducing the use of healthcare resources. ⋯ Pulmonary rehabilitation was effective in improving symptoms and quality of life and reducing the utilization of healthcare resources over 18 months. The results were consistent across participating centers despite variations in practice settings, patient referral patterns, and program structure.

Comparative StudyA new unsupported upper limb exercise test for patients with chronic obstructive pulmonary disease.
PURPOSE This study aimed to develop a new unsupported upper limb exercise test (UULEX) for patients with chronic obstructive pulmonary disease (COPD). ⋯ The findings suggest that the new UULEX test is a reproducible and acceptable exercise test for patients with COPD that can be used as a simple method to evaluate upper limb function in these patients. Further studies are required to determine the external validity of the test and its sensitivity to interventions such as pulmonary rehabilitation.

Questioning the use of heart rate and dyspnea in the prescription of exercise in subjects with chronic obstructive pulmonary disease.
This study examined the heart rate and dyspnea responses during constant submaximal lower limb endurance exercise in subjects with chronic obstructive pulmonary disease (COPD) to determine the appropriateness of using target heart rate or dyspnea for the prescription of endurance exercise intensity. ⋯ Setting heart rate and dyspnea targets for endurance training at an intensity equivalent to 60% VO(2peak) may be inappropriate for subjects with moderate to severe COPD because heart rate and dyspnea increase independently of workload at this intensity.

Criterion validity of the Duke Activity Status Index for assessing functional capacity in patients with chronic obstructive pulmonary disease.
This study evaluated the concurrent criterion validity of the Duke Activity Status Index (DASI) with respect to standard physiologic work capacity indices in patients with chronic obstructive pulmonary disease (COPD) and compared its performance with similar surrogates. ⋯ DASI has high criterion validity for predicting CE and/or AE outcomes in the COPD population. It is warranted in addition to the 6MWD, and its predictive significance and simplicity recommends it over several other self-administered instruments for evaluating functional capacity.
