Algorithms and Measures

Physical Activity

Physical activity and functioning are essential to understanding the clinical outcomes across a wide range of chronic conditions

Physical Activity

Physical Activity

Traditionally, in-clinic performance-based outcomes such as the 6-minute walk test and patient reports are used to assess physical functioning. Compared to these traditional assessments, ActiGraph technology collects objective measures of physical functioning remotely and continuously. These outcomes not only reflect patients’ function in the real-world, remote assessments reduce barriers to study participation and lead to greater success in recruitment and completion, especially in clinical populations with impaired mobility.

Commonly Used Physical Activity Measures

  •   Moderate to Vigorous PA (MVPA)
  •   Sustained Physical Activity Bouts
  •   Non-Sedentary Time
  •   Step Count and Metabolic Equivalents (METs)
