  1. Read the article on pages 2–7.
  2. Complete the examination.
  3. 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 to the article, “Clinical Benefits of Stance Control Orthosis Systems: An Analysis of the Scientific Literature” by Britta Zacharias, Dipl-Ing (FH), Andreas Kannenberg, MD, PhD.

Quiz – Clinical Benefits of Stance Control Orthosis Systems: An Analysis of the Scientific Literature, Britta Zacharias, Dipl-Ing (FH), Andreas Kannenberg, MD, PhD.

  1. [Select the correct response.] Of the 171 articles analyzed initially, only _____________ remained for the final literature analysis.
    • A. 23
    • B. 32
    • C. 47
  2. True or False _____________ In the last part of the stance phase, unlike with a stance control orthosis, the extension moments are much higher than normal with a locked KAFO.
  3. [Select the correct response.] Several studies demonstrating walking with an SCO showed in particular reduced _____________ on the orthotic side.
    • A. medial obliquity
    • B. pelvic obliquity
    • C. sagittal obliquity
    • D. transversal obliquity
  4. True or False _____________ A compensatory movement with a locked KAFO is a pronounced plantarflexion of the sound foot in the stance phase.
  5. True or False _____________ The influence of an SCO on the reduction of plantarflexion seems to be clearly greater for experienced orthosis users than for first-time users.
  6. True or False _____________ The results of the literature search indicate that the use of a stance control orthosis versus a locked KAFO can clearly reduce or even eliminate the necessity of compensatory movements.
  7. [Select the correct response.] Overall, the gait pattern of patients walking with a stance control orthosis was consistently assessed as _____________.
    • A. more systematic and fluid
    • B. more symmetrical and natural
    • C. smoother and more even
  8. True or false _____________ Many patients said that they would accept the greater weight and bulkier nature of an SCO if it were reliable and walking with it proved to be easier than with a locked orthosis.
  9. [Select the correct response.] According to the article, which of the following was a perceived benefit of an SCO?
    • A. easier to walk
    • B. required less concentration
    • C. conducive to greater mobility
    • D. easier to control
    • E. less strenuous
    • F. all of the above
    • G. none of the above
  10. True or False _____________ Due to the paucity of patients and small population sizes, adequate levels of statistical significance were often not reached for many of these studies.
  11. True or False _____________ Several of the SCOs allow the knee joint of the orthosis to be flexed when loaded, thereby permitting alternate ramp and stair descent.
  12. True or False _____________ According to the article, the diversity of the product-specific demands on patients may actually contribute to the failure of the SCOs to prevail to a larger extent over locked KAFOs.
