A method to compare new and traditional accelerometry data in physical activity monitoring

A method is developed that facilitates the compatibility between both methods through conversion of raw accelerometer output data collected with inertial acceleration sensors into Actigraph counts — the most widely used (de facto standard) device brand in epidemiological studies.

Accelerometers and pedometers: methodology and clinical application

This review examines recent literature on the validation of movement sensors to assess habitual physical activity and suggests new technologies, including the combination of accelerometry with the measurement of physiological parameters, have great potential for the increased accuracy of physical-activity assessment.

Evolution of accelerometer methods for physical activity research

A collaborative approach towards analytic methods is proposed to facilitate PA research, which requires a shift away from multiple independent calibration studies and makes the case for a distinction between PA represented by accelerometer-based devices and PA assessed by self-report.

A Review of Accelerometry-Based Wearable Motion Detectors for Physical Activity Monitoring

This paper reviews and compares existing commercial products to provide a comprehensive outlook of current development status and possible emerging technologies of wearable accelerometry-based motion detectors.

Modeling physical activity outcomes from wearable monitors.

An algorithm embodying best practice recommendations for collecting, processing, and reporting physical activity data routinely collected with accelerometry-based activity monitors is presented, proposed as a linear series of seven steps within three successive phases.

Assessing physical activity using wearable monitors: measures of physical activity.

The quantitative assessment of physical activity using wearable monitors is grounded in the measurement of energy expenditure and sensors and methods for quantitatively assessing physical activity should be validated in laboratory and free-living populations using criterion methods of calorimetry or doubly labeled water.

Validity of accelerometry in high-intensity complex movements

It is found that GT3x was not particularly valid for assessing energy expenditure in high intensity complex activities and was found to prefer before the Y-axis solely when using the accelerometer for estimations of EE.

Integration of physiological and accelerometer data to improve physical activity assessment.

The combination of HR and ACC improves the accuracy of PAEE estimates and could be applied in large-scale epidemiological studies.

Protocols for evaluating equivalency of accelerometry-based activity monitors.

Issues associated with monitor equivalency are summarized and methods for standardization and quality control in future research are proposed.

Calibration of accelerometer output for children.

The calibration of four different accelerometers used most frequently to assess physical activity and sedentary behavior in children are reviewed and alternative data processing using the raw acceleration signal is recommended as a possible alternative approach where the actual acceleration pattern is used to characterize activity behavior.

Reliability of accelerometry-based activity monitors: a generalizability study.

The CSA/MTI appeared to have acceptable reliability for most research applications and values with the other devices indicate some possible concerns with reliability, but additional work is needed to better understand factors contributing to variability in accelerometry data.

Validity of accelerometry for the assessment of moderate intensity physical activity in the field.

The count versus METs relationship for accelerometry was found to be dependent on the type of activity performed, which may be due to the inability of accelerometers to detect increased energy cost from upper body movement, load carriage, or changes in surface or terrain.

A comparative evaluation of three accelerometry-based physical activity monitors.

Evaluating the absolute and relative validity of three contemporary activity monitors under both laboratory and field conditions found the CSA yielded accurate predictions of energy expenditure (EE), whereas the Tritrac and Biotrainer tended to overestimate the EE (101-136% of measured value).

Prediction of activity energy expenditure using accelerometers in children.

Both accelerometer-based activity monitors provided valid measures of children's AEE and PAR, and can be used to discriminate sedentary, light, moderate, and vigorous levels of physical activity but require further development to accurately predict A EE and PAR of individuals.

Assessment of energy expenditure for physical activity using a triaxial accelerometer.

Although sedentary activities and walking represent a large part of normal daily physical activity, the validity and usefulness of the triaxial accelerometer--measuring IAAtot--to predict EEact in daily life must be studied under free-living conditions.

Estimation of energy expenditure using CSA accelerometers at hip and wrist sites.

Estimation models that relate hip and wrist accelerometer data to energy expenditure (EE) in field and laboratory settings are established and the small amount of additional accuracy gained from the wrist accelerometers is offset by the extra time required to analyze the data and the cost of the accelerometer.

The term "calibration" in accelerometry research has come to mean the conversion of counts into other established measurement units. In this article, two types of calibration research are described.

Validity of four motion sensors in measuring moderate intensity physical activity.

Motion sensors tended to overpredict EE during walking, however, they underpredicted the energy cost of many other activities because of an inability to detect arm movements and external work.

Measuring daily behavior using ambulatory accelerometry: The Activity Monitor

The AM is based on ambulatory accelerometry, the aim of which is to assess postures and motions for long-term (>24-h) measurement periods during normal daily life and has many possibilities in behavioral research.
