Accelerometer measurement differences between the preferred and non-preferred wrist

Description
Summary:Differences in movement between the preferred arm, most commonly used to perform daily living tasks, or non-preferred arm may result in different physical activity estimates when using accelerometry. Therefore, this study compared measured physical activity, using an Actigraph Link, between the preferred and non-preferred wrist during college students’ structured daily college activities and free-living conditions. 30 participants completed 7 lab tasks wearing an accelerometer on each wrist followed by 7 days of free-living data. Average vector magnitude (AVM) of counts per minute during lab activities and free-living conditions were compared between the preferred and non-preferred wrists. AVM was significantly higher in the preferred wrist compared to the non-preferred during basketball (preferred = 22,753.9 (SD 4,013.6) vs non-preferred = 20,655.6 (3,196.5), p  = .003), and racquetball (15,248.4 (3,503.9) vs 12,030.0 (3,115.6), p
