  1. Read the article on pages 21–24.
  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 the article: “Dynamic Foot Orthosis and Motor Skills of Delayed Children,” by Kenneth H. Pitetti, PhD, FACSM, and Valerie C. Wondra, RPT.


Please allow 2–4 weeks for processing.

  1. Dynamic Foot Orthoses (DFOs) are shoe inserts that contain one layer of ________ and a thin layer of polyethylene ________designed to give mild mechanical support and proprioceptive feedback to children with subtle neurological anomalies.
  2. Which of the following was NOT a criterion for eligibility to participate in the study: These children had to:
    1. be above the age of 60 months
    2. be diagnosed with gross motor delay, as defined by the Peabody Developmental Motor Scales Test
    3. be enrolled in an early intervention program, including direct physical therapy at least once every week
    4. be medically stable for therapy (as determined by the child's pediatrician)
    5. have the informed consent of a parent or guardian.
  3. The z score figure used in the study to indicate gross motor delay was ___________ or lower.
  4. True or False? The minimum controlled dynamic foot orthosis (DFO) used for this study is a shoe insert consisting of a thin layer of plastic on the bottom of dense foam (aliplast-like material) contoured and shaped to fit the plantar surface of the foot.
  5. [Fill in the blank with the correct term.] semi-flexible / rigid / flexible
    • The study DFO is ____at the toe,
    • ________at the arch, and
    • ________around the heel.
  6. True or False? The sizing of the study DFO correlates to the weight of the patient.
  7. True or False? When fitting the child with the study DFO, it is important to match the heel and metatarsal heads to the heel pocket and metatarsal depressions, respectively.
  8. [Fill in the blanks with the correct numbers.] The Peabody Developmental Motor Scales Test, 2nd edition (PDMS-2) has been shown to be a reliable and valid method of determining motor skills in children _________to ________ years of age.
  9. Name three (3) locomotor items used in the PDMS-2:
  10. a.
  11. True or False? Concerning test results, significantly higher raw scores and age equivalent scores were seen WITHOUT inserts when compared to WITH inserts.
  12. True or False? The disability category that demonstrated the largest improvements were those children who were developmentally delayed.
  13. [Circle the correct answer.] The results of this study suggest that DFOs DEFINITELY DO / COULD PERHAPS / DEFINITELY DO NOT play a significant role in improving the locomotor skills of children with gross motor delays.
