JPO SELF-ASSESSMENT EXAMINATION
TO EARN TWO PCE CREDITS:
- Read the article on pages 113–120.
- Complete the examination.
- Submit your completed examination to the AAOP per the directions on the next page.
The following questions require short answers only; you do not have to use complete sentences. All questions refer the article: “Effect of the Weight of Prosthetic Components on the Gait of Transtibial Amputees,” by Hamid Bateni, PhD, CPO, and Sandra J. Olney, PhD.
Please allow 2–4 weeks for processing.
- List three (3) factors known to affect the characteristics of an amputee’s gait:
- True or False: In the last decade a factor that has become an integral component of competition among prosthetic components designers and manufacturers has been the weight of the component.
- Select the correct answer: A comparison of available components that affect the prosthetic weight has Never/Often been made.
- Name one useful tool to evaluate gait and determine efficiency of walking:__________________________________________
- Circle theINCORRECTpercentage figure: TTAs spenda) %9% b) 20% c) 41% d) 67% more energy for walking when compared to the able bodied.
- List the two (2) commonly-used methods of assessing metabolic energy cost:
- Select the correct answer: During the testing procedure, by replacing prosthetic parts, the prosthetic weight was changed by _____________________ grams.a) 181 b) 203 c) 169
- Select the correct answer: [Substantial / No Substantial] differences in relative angles were noted between steel and titanium trials.
- True or False: The positive work of the hip tended to be greater when steel components were used, relative to titanium.
- List two (2) differences reported by test participants when prosthetic components were changed:
- Circle the correct answers:
True or False: Test results indicate a significant difference in energy expenditure when steel components were replaced with titanium.
True or False: The low PCI when using titanium components, as indicated by test results, suggests that participants were performing a more economical gait when using the light materials.
- The results of the study showed that there were some / there were no consistent differences in the kinematic and kinetic factors of the amputee gait when the steel prosthetic components were replaced by titanium.
- The results also suggest that small changes in the weight of a prosthetic limb [do / do not ] affect the stance time of the affected side.
