The validity and reliability of these devices is proven for healthy adults between 18 and 64. Objectives: Comparing data output of two devices. Methods: Observational case study on a test track and in the domestic environment of a 80- year-old female multimorbide geriatric patient. Results: High significant correlation of the devices on the test track [r=.776, p≤.001, Bca-CI-95\% (.618;.874), N=33], but significant different in the domestic environment over time (z=4.840, p≤.001). Conclusion: The dominant/non-dominant body side and further sources of error may play a role in monitoring steps with these devices.}, language = {en} }
