Establishing the Validity and Reliability of a Novel Wearable Physical Activity Monitoring System for Older Adults
Wearable physical activity monitors have become increasingly commonplace as commercial fitness products. However, current devices can be expensive and cannot accurately measure activity for older adults. Xerus, Inc. has recently built an affordable activity tracking system able to measure physical activity levels in older adults. However, the accuracy of Xerus activity tracking monitor has not been tested. Thus, the objective of this study is to determine the accuracy of the Xerus activity monitor to measure physical activity in older adults while performing mobility tasks. These tasks include walking on a treadmill at different speeds, a six-minute walking test and walking up and down stairs. The results will determine the accuracy of Xerus activity monitor and its readiness for clinical use.
