Use of pedometers and accelerometers in clinical populations: validity and reliability issues

摘要: Abstract Background: Pedometers and accelerometers are often used in clinical research studies, have the potential to provide valid objective information on physical activity. Objectives: The purposes of this review introduce clinicians various activity monitors that commercially available, discuss their strengths limitations. Scientific articles over past 20 years were reviewed, most common types identified. Emphasis was placed devices with established validity reliability, which acceptable participants did not interfere activities. Ease-of-use from investigator's standpoint also considered. Major findings: A number identified, including four pedometers (Yamax SW digiwalker, New Lifestyles NL-2000, Omron HJ-720 ITC, StepWatch), three accelerometer-based (ActiGraph, Actical, RT3), a multisensor device (Sensewear Armband). Validity and...
