  1. Time represents the linear effect of time. Time2 represents the quadratic effect of time. Time3 represents the cubic effect of time. Touch Effect was entered as a dummy variable (resting control group = 0, soft shoulder massage = 1, vagus nerve massage = 1). Time × Touch Effect represents the interaction between the linear effect of time and Touch Effect. Time2 × Touch Effect represents the interaction between the quadratic effect of time and Touch Effect. Time3 × Touch Effect represents the interaction between the cubic effect of time and Touch Effect.
