Short-term and long-term effect of intermittent doffing for posterior
and anterior regions in sockets with pin (upper) and vacuum or suction (lower)
suspension. “Benefit” occurred when the experimental session (B)
rate of change was higher (less negative) than both control session rates of
change (A1, A2), B > A1 and B > A2. “No Effect” was
indicated by the experimental session rate of change in between control session
rates of change, B > A1 and B < A2, or B < A1 and B
> A2. When the experimental session rate of change was lower (more
negative) than both control session rates of change, B < A1 and B
< A2, this signified “Detriment.”
