  1. Read the article on pages 70–82.
  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, “The Use of Preparatory/Evaluation/Training Prostheses in Developing Evidence-Based Practice in Upper Limb Prosthetics” by Carl D. Brenner, CPO and Joseph K. Brenner, CP.


Please Allow 2–4 weeks for processing.

  1. True or False ___________________ A significant challenge regarding the gathering of statistically relevant information for this study was the limited number of upper limb prostheses in comparison to lower limb prostheses.
  2. [Select the correct response.] When considered at the most elementary operational level, the normal, fully functional human arm provides at least ___________________ degrees of freedom, including ___________________ voluntary, independent movements, without counting the individual motions of each separate digit.
    1. 8…12
    2. 12…16
    3. 8…16
    4. 8…12
  3. True or False ___________________ Unlike lower limb prosthetics which can benefit from the effects of gravity and ground reaction forces to enhance involuntary prosthetic function, the upper limb amputee must consciously control each separate function of the upper limb prosthesis.
  4. [Select the correct response.] It ___________________ necessary to fit a P/E/T prosthesis for each type of socket being initially evaluated.
    1. is
    2. is not
  5. [Select the correct response.] The body-powered P/E/T prosthesis is particularly beneficial to the new amputee in its ___________________ role because of its effectiveness in controlling edema, protecting the residual limb, and reducing the patient’s pain and anxiety.
    1. preparatory
    2. evaluation
    3. training
  6. [Select the correct response.] The body-powered mechanical P/E/T prosthesis is ideally fitted to the patient ___________________ the sutures have been removed, generally about ___________________ days after amputation.
    1. before…21
    2. after…21
    3. before…14
    4. after…14
  7. [Select the correct response.] The P/E/T ___________________ prosthesis, with its interchangeable modular design, makes it very easy for the clinic team and the patient to try out a large variety of socket designs, suspension systems, combined with body-powered control systems.
    1. body-powered
    2. hybrid
    3. externally-powered
  8. [Select the correct response.] Although pronation and supination can be preserved, to some degree, in an uncomplicated wrist disarticulation amputation, usually only ___________________ of the full range of forearm rotation is expected to be functionally available.
    1. 30%
    2. 40%
    3. 50%
    4. 60%
  9. True or False ___________________ The P/E/T electronic prosthesis is best used in those situations where an externally powered elbow would restore function not available with a body-powered system.
  10. True or False ___________________ The trial prosthesis and a P/E/T electronic prosthesis share many similarities, such as both systems are intended for temporary use and may or may not eventually be replaced by a definitive prosthesis. Another similarity is that both are used as an investigative tool.
  11. [Select the correct response.] In prosthetics, the ___________________ is generally regarded as the completion of his prosthetic care, and is often the focus of the treatment plan.
    1. secure and proper fit of the trial prosthesis
    2. acceptance of the prosthesis by the patientÆs health care plan
    3. delivery of a patient’s definitive prosthesis
  12. [Select the correct response.] With improvements in sensor technology, biomaterials using nanotechnology, imbedded chips, artificial intelligent algorithms and programmable miniature microprocessors ushering in, what could be described as the ___________________ era, new methods are needed to discern the most appropriate technology for each individual patient.
    1. biomechatronic
    2. biomechanical
    3. nanoelectric
    4. megabiologic
    5. electrobiomechanical
