The purpose of this research was to determine whether prior activity affected the
shape of a plaster cast taken of a transtibial residual limb. Plaster casts were
taken twice on one day in 24 participants with transtibial limb loss, with 5 s
between doffing and casting in one trial (PDI-5s) and 20 min in the other trial
(PDI-20m). The ordering of the trials was randomized. The mean +/- standard
deviation radial difference between PDI-20m and PDI-5s was 0.34 +/- 0.21 mm when
PDI-5s was conducted first and -0.02 +/- 0.20 mm when PDI-20m was conducted
first. Ordering of the trials had a statistically significant influence on the
mean radial difference between the two shapes (p = 0.008). The result shows that
prior activity influenced the residual limb cast shape. Practitioners should be
mindful of prior activity and doffing history when casting an individual's limb
for socket design and prosthetic fitting.
