Activity Pacing Interventions
Thirty-two adults with symptomatic hip or knee OA
stratified by age and gender were randomized into the
tailored or the general activity pacing intervention group.
Randomization was done by generating a randomized
schedule using SAS software (SAS Institute, Inc., Cary,
NC) in which participants were assigned to the tailored
or general activity pacing groups on the basis of whether
they were “young” or “old” (using a cut-off age that was
the mean age The PI was the first author (SM) of participants
in a previous study; Murphy, Smith, Clauw,
et al., 2008) and on gender. The principal investigator
(Susan Murphy) was blinded to participant assignment.
Regardless of group assignment, all participants met with
an occupational therapist for two one-on-one sessions
(total treatment time: 1.5 hr) over a 2-wk period
