AoM_Total total amount of motion, ∆HR heart rate change, AoM_G amount of motion during gait, AoM_NG amount of motion during non-gait, CI confidence interval, AIC/BIC Akaike/Baysian Information Criterion with maximum likelihood, *** p <0.001, ** p < 0.01, * p < 0.05.
^aNote that models with AoM_Total and AoM with both gait and non-gait portions (AoM_G and AoM_NG) best represent the data as opposed to AoM during gait only (AoM_G) and step number
