Comparing Two Moderate-to-Vigorous Physical Activity Accelerometer Cut Points in Older Adults With Neck and Back Disabilities Undergoing Exercise and Spinal Manipulation Interventions.

Comparing Two Moderate-to-Vigorous Physical Activity Accelerometer Cut Points in Older Adults With Neck and Back Disabilities Undergoing Exercise and Spinal Manipulation Interventions. J Aging Phys Act. 2019 Nov 07;:1-7 Authors: Malone Q, Passmore S, Maiers M Abstract Different techniques used to analyze and reduce accelerometer data may impact its interpretation. To determine which variables were impacted by changing analysis parameters, the authors performed a secondary analysis of data gained from a clinical trial conducted on older adults (aged ≥65 years; M = 71.1 and SD = 5.3; n = 100) with neck and back disabilities and compared the effects of two different cut- point sets (Matthews and Freedson sets) commonly used to analyze older adult accelerometry data. The Matthews set was found to assign significantly greater moderate-to-vigorous physical activity per day than the Freedson set in all comparisons. This suggests that, if moderate-to-vigorous physical activity per unit time is a primary outcome measure, the choice of which analysis method is used should be carefully considered. Further results from analyses of dependent variables, time in moderate-to-vigorous physical activity bouts of >10 min/day, mean bout length, and number of bouts per day are discussed.
