Pulmonary rehabilitation (PR) improves activity tolerance. Outcome measures like wrist actigraphy need to be tested to verify reliability and validity during exercise activities. PURPOSE: To determine the ability of wrist actigraphy to accurately reflect motion during PR exercise in patients with moderate-to-severe COPD. METHODS: A total of 20 subjects (8 male, 12 female) with COPD (FEV1% predicted 40.8+21.2%; FEV1/FVC ratio 51.7+16.2%) were enrolled. Each subject wore Octagonal Basic Motionlogger« (AMI, Ardsley, NY) during 2 PR sessions. The PI (GSB) directly observed all sessions and recorded exercise start-stop times of exercise types including upper extremity endurance (UEE), lower extremity endurance (LEE) and lower/upper extremity resistance (LEUER). Each exercise type was isolated. The zero-crossing-mode (ZCM) and time-above-threshold (TAT) mean and standard deviation were generated. The ZCM and TAT scores were calculated by dividing the mean by the standard deviation to stabilize within subject variability. The average movement duration (AMD) was calculated using Leidy's formula (1997): (TAT/ZCM) *200.RESULTS: Reliability using test-retest (1-week) was reported as Cronbach's alpha:AMD total=0.878, AMD UEE=0.50, AMD LEE=0.851, AMD LEUER=0.569. Criterion validity of the wrist actigraph to reflect training type was determined by correlating type to the type AMD score using a Spearman's rho: AMD total exercise r -0.564(p=0.14); AMD UEE r 0.564(p=0.01); AMD LEE r -0.104(p=0.55); and AMD LEUER r -0.576(p=0.01). In comparison to the PI-generated log data, the actigraphs provided consistent patterns of motion vs. rest. Reliability may be lower in the UEE group as 5 subjects missed this exercise type at 1 session, reducing the sample. Criterion validity is established that wrist actigraph accurately reflects UEE and LEUER training. CONCLUSION: These findings support that wrist actigraphy is a reliable and valid measure of UEE and LEUER during PR. [Poster Presentation]
