title: Wrist actigraphy validation of exercise movement in COPD.
abstract: A wrist actigraph is a device used in sleep research studies to measure whole body movements. The purpose of this study was to evaluate the feasibility, sensitivity, and validity of wrist actigraphy during pulmonary rehabilitation (PR) upper-extremity exercise in chronic obstructive pulmonary disease (COPD) patients. In this study, 20 patients wore Octagonal Basic Motionlogger actigraphs during two 90-minute PR sessions while the investigator recorded details of the subject's upper-extremity movements. Concurrent validity with supervised exercise records was supported for upper-extremity endurance (UEE) intensity at baseline (r = .885, p < .001) and 1 week (r = .935, p < .001). Criterion validity was supported for UEE (r = .56, p = .01) and combined lower- and upper-extremity resistance (r = .72, p < .01) compared with rank-ordered type of exercise. Wrist actigraphy is shown to be a feasible, sensitive, and valid instrument to measure upper-extremity movement during PR in COPD patients.
