Feasibility
Regarding intervention feasibility, a total of 177 were initially
screened, and 86 patients were potentially eligible. After the
principal investigator approached each, 23 individuals were
eligible and agreed to participate. Of the 63 individuals
remaining, 56 individuals were ineligible (65.12%) and seven
refused (23.33%). See Figure 1 for reasons given. Overall
retention for the study was 91%.
Of the 11 participants who were randomized to the CSEP
and adhered to structured walking prescriptions as reported
on daily logs, the mean minutes walked per session was 28.53
(SD = 4.49), with a frequency of 3.07 (SD = 2.43) days per
week and a mean intensity of 11.78 (SD = 0.94) on the Borg
scale. Objective data further supported that the CSEP was
feasible by increasing daily steps walked, with a mean
increase of 5920 steps (SD = 1523) from baseline to 12-week
post-intervention. An independent-sample t test indicated
that the 12-MWT was significantly different for participants
who completed the study in the exercise group from baseline
to week 10 than for those in the attention control group
(t = 2.28, P = 0.04).
