Validity, reliability, and feasibility of the uSense activity monitor to register physical activity and gait performance in habitual settings of geriatric patients
Objective : The aim of the study was to investigate the psychometric quality of a newly developed
activity monitor (uSense) to document established physical activity parameters as well as innovative
qualitative and quantitative gait characteristics in geriatric patients. Approach : Construct and
concurrent validity, test-retest reliability, and feasibility of established as well as innovative
characteristics for qualitative gait analysis were analyzed in multi-morbid, geriatric patients with
cognitive impairment (CI) ( n = 110), recently discharged from geriatric rehabilitation. Main
results : Spearman correlations of established and innovative uSense parameters reflecting active
behavior with clinically relevant construct parameters were on average moderate to high for motor
performance and life-space and low to moderate for other parameters, while correlations with uSense
parameters reflecting inactive behavior were predominantly low. Concurrent vali...
