What is the best mode of transmission for an EADL that controls a distant device such as a garage
door opener? - Answer-EADLs are electronic aids to daily living. However, radio frequency transmission
is the best choice for use with distant
devices like garage door openers because it is not impeded by most materials except for grounded
metal.
What is the main difference between the RESNA Code of Ethics and the RESNA Standards of
Practice for Assistive Technology Practitioners and Suppliers? - Answer-The RESNA Code of Ethics lists
specific modes of moral conduct to be adhered to; it includes a
statement about informing and educating the public about assistive technology, in addition to
statements related to moral conduct that other disciplines use. (A) is incorrect because the
Standards of Practice actually is broader in scope that the Code. (B) is wrong because both are
specific to the Assistive Technology field, although many of the standards are similar to those given
in other medical standards of practice statements. (D) is incorrect since neither document actually
outlines a specific quality assurance program.
What is the threshold for a person being tested by pure tone audiometry? - Answer-In pure tone
audiometry, thresholds are generally determined at frequencies ranging from
0.125 to 8 kHz as the intensity in dB that the person hears each tone 50 percent of the time in each
ear. Decibels represent the amplitude of sound. Intensity (A) also represents a threshold in terms of
the frequency of audible sound; that is not the meaning of "threshold" in pure tone audiometry, but
the test does give an idea of the range of audible frequencies. Option (C) is one threshold for a
normal individual without hearing loss. Option (D) is what is evaluated in another assessment, the
speech recognition test.
,What stage of processing has the greatest effect on reaction time in an individual with apraxia? -
Answer-The largest component contributing to reaction time is cognitive processing in the central
nervous system (CNS). This is true for normal individuals (typically 70 to 300 milliseconds, ms), but
it is amplified in people with apraxia who have an inability to perform complex movements through
CNS involvement (such as with brain damage) but have intact peripheral systems. Normally typical
times are up to 38 ms for sensory reception (A), from 2 to 100 ms for neural transmission to the
CNS (B), 10 to 30 ms for neural conduction to the muscle (D), and 30 to 70 ms for a fourth
component, latency and activation time of the muscle.
Generally, what is the first step in ascertaining potential sites for control of assistive devices in a
person with physical disabilities? - Answer-The first step generally is to assess seven functional hand
grasp patterns, because the ideal
control sites are the hands and fingers. Option (B), in which the individual uses his or her thumb to
point to corners or touch them by hand using a range and resolution board, is usually performed
after the functional grasp patterns. If the person cannot use his or her hands for controls, then
range and resolution are determined using less preferable sites, which in decreasing order of
preference are the head (D) or mouth, the feet (C), and arms or legs. Sometimes the chin, forehead,
or eye movement is used for control.
Which of the following is NOT an example of the use of AAC in a child with an autism spectrum
disorder? - Answer-Voice recognition software is really more a tool for people who have cognitive
disabilities that
curb their ability to write, such as those who have suffered traumatic brain injury (TBI). The other
options are all examples of AAC, augmentative and alternative communication systems, which are
appropriate for individuals with autism spectrum disorder (ASD). ASD is a developmental disorder
primarily distinguished by challenges related to social interaction, verbal and nonverbal
, communication, and repetitive, stereotypical conduct. Use of static visual symbols (A), contextual
clues or prompts (B), and PECS, the Picture Exchange Communication System (C), have all been
found useful for individuals with ASD.
Which of the following components is part of operational competence training by the ATP for a
consumer receiving an assistive device? - Answer-All of these responses are ways of facilitating assistive
technology performance once a device
is delivered to the consumer. Answer (C) describes training that facilitates operational competence.
Option (A) describes what is involved in training the person in achieving strategic competence,
which is application of the device. Performance aids (B) and written instructions (D) are not
training tools per se, but rather aids to help the person remember what to do.
Which of the following is NOT a means of measuring user satisfaction as an outcome measure for
use of assistive technology? - Answer-The only outcome measure listed that does not evaluate user
satisfaction is FIM, the Functional
Independence Measure. FIM is a functional performance measurement of eighteen items such as
self-care and communication, but it is basically useless in terms of evaluating assistive technology
because maximal scores can only be obtained without use of such devices. QUEST (A) stands for the
Quebec User Evaluation of Satisfaction with Assistive Technology, which consists of two sections, a
user satisfaction questionnaire and a portion scoring variables related to satisfaction. COPM (B)
stands for the Canadian Occupational Performance Measure, which evaluates the person's
selfacknowledged
goals and satisfaction. Assistive technology abandonment (D) is a gauge of
dissatisfaction.
