- Walking-Ambulation Objective Measure
Description
An accelerometer is used to measure the intensity of movements continuously over a desirable study period (for a robust assessment of free-living physical activity, a minimum of 4 days is recommended; 7 days of continuous measurement is the most common). It is generally recommended to select the highest time resolution (or the shortest epoch) possible to last over the entire study period. Most current accelerometers have sufficient memory and battery capacity. The participant is asked to wear the accelerometer during all waking hours of the study period. Most monitors are not waterproof, and are not recommended for activities such as swimming and showering. An additional daily record of wearing the monitor can be taken to identify non-wearing time activity. Data are downloaded from the accelerometer after being retrieved from the participant. Although this is the current standard for objective physical activity measurements, more advanced sensor and processing technologies are rapidly evolving in this field to improve accuracy and expand usability.

Personnel and Training Required
The individual who programs the accelerometer, collects the data from the participant, and downloads the data must be trained. The accelerometers user manual must be used to complete the procedures properly.Equipment Needs
Personal computer, accelerometers, download ports or readers (for some), battery chargers (for some) and replaceable batteries (for others).Requirements
| Requirement Category | Required |
|---|---|
| Major equipment | No |
| Specialized training | No |
| Specialized requirements for biospecimen collection | No |
| Average time of greater than 15 minutes in an unaffected individual | No |

Selection Rationale
There are several accelerometers that can measure physical activity, but the costs, accuracy, sensitivity, complexity, and research applicability vary widely. Several accelerometers have been shown to be applicable in heterogeneous subject populations. While the cost remains relatively high (around $350), they provide detailed physical activity data registered in good time resolutions (typically minute-by-minute or better). The intensity measures from the accelerometers closely represent energy expenditure, and with high data resolution, patterns of movements can also be studied. Accelerometers have low user burden (lightweight and small size, allowing multiple uses, and with rechargeable batteries), and data can be directly downloaded for research. The GT3X accelerometer (Actigraph) is used as an example of a typical accelerometer protocol.
