Research Letter: Sensor-Based Systems and the Objective Measure of Physical Activity

Similar to medication adherence, objective measures of physical activity may allow physicians to improve activity rates among individual patients and patient populations, which should improve health care outcomes. Sensor-based systems may become a best practice for objective measurement of physical activity and the management of physical activity programs. Given the ease of tracking with these new devices and the ability to upload information automatically, a sensor-based system has the potential to prevent preventable diseases and lower health care costs.
