Wrist-worn activity monitors do not directly measure steps, but instead measure wrist movements that occur during ambulation. Due to the

Wearing the accelerometer on the (non-dominant) wrist is gaining popularity as an alternative to hip placement ( Doherty et al., 2017 ; Schrack et al., 2016 ; Troiano, McClain, Brychta, & Chen, 2014 ). Wrist-worn accelerometers have been shown to be valid in estimating physical activity energy
