Physical activity across abilities

Physical activity is an important factor of health for individuals of all ages and activity abilities. Many studies have developed and validated physical activity measurements for healthy populations. However, the accuracy and ability to apply these measures to populations with gait deviations and/or walking aids is less studied. This study had two main aims: 1) evaluate a step count algorithm by Maylor et al. at different walking speeds and accelerometer placement and 2) evaluate effect of AD use on acceleration profile metrics and step count accuracy.
