Quiz – The Effectiveness of a Modified Icex Casting Technique Based on Circumferential Change in Residual Limb Volume, Jonathan D. Day, CPO, LPO

[Correct response indicated in bold font.]

1. [Select the correct response.] According to the article, ______________ a residual limb is crucial to producing a well-fitting prosthetic socket.
• A. designing
• B. adjusting
• C. casting
2. (True or False) ______________ Prosthetists base their selection and application of a particular casting technique both on their anecdotal experience and on their foundational education.
3. [Select the correct response.] Based on existing literature, _____________ scientific evidence exists to guide a prosthetist’s choice of casting technique.
• A. little-to-no
• B. a moderate amount of
• C. a plethora of
4. [Select the correct response.] The air bladder and pump are connected and the bladder is pressurized to about _____________ while the plaster cup is _____________.
• A. 10 mm Hg…drying
• B. 20 mm Hg…curing
• C. 20 mm Hg…settling
• D. 10 mm Hg…hardening
5. (True or False) ____________ Five-inch rigid plaster is used to apply two layers over the residual limb, minimizing any overlap through a shift technique.
6. [Select the correct response.] Large areas of overlap and using too many layers of plaster ____________ the effectiveness of the pressure bladder.
• A. increases
• B. maintains
• C. reduces
7. (True or False) _______________ Only patients who underwent a unilateral transtibial amputation and were cast using the Icex casting procedure were included in the study.
8. (True or False) ______________ Most of the 82 amputations included in the study were caused by diabetes or trauma.
9. [Select the correct response.] The mean volume reduction produced by the pressurized casting technique was statistically significant at ___________ level(s).
• A. one
• B. two
• C. all three
10. (True or False) ______________ The volume reduction impacted the effectiveness of the casting technique, but it did not change the shape of the residuum.
11. [Select the correct response.] The impact of vacuum-assisted casting on the residual limb’s volume is ____________.
• A. measurable
• B. quantifiable
• C. unknown
12. (True or False) _____________ The difference in volume reduction is attributed to the amount of bone present and limited soft tissue in the proximal region of the residuum.
