1. A 45-year-old individual with C5 spinal cord injury is being evaluated for a power
wheelchair seating system. The client demonstrates a posterior pelvic tilt and a tendency to
slide forward in the chair. What is the most appropriate initial seating intervention to
address this postural deviation?
A. Install a flat planar seat cushion with no contours
B. Incorporate an anti-thrust seat contour combined with a properly positioned pelvic
positioning belt anchored at a 90-degree angle
C. Adjust the footrests to their highest vertical position to flex the hips past 120 degrees
D. Remove the backrest support to encourage active trunk extension
Answer: B
An anti-thrust seat contour, when paired with a pelvic positioning belt mounted at an optimal
angle (typically 45 to 90 degrees depending on the client’s hip flexion range), prevents forward
migration of the pelvis and counteracts posterior pelvic tilt by blocking the ischial tuberosities
from sliding forward.
2. During an initial seating and mobility evaluation for a client with progressive multiple
sclerosis, the Assistive Technology Professional (ATP) must prioritize which of the
following assessments to ensure long-term equipment utility?
A. Assessing current functional capabilities only, without accounting for future disease
progression
B. Documenting anticipated functional declines, muscle fatigue patterns, and potential future
support requirements
C. Selecting the least expensive manual wheelchair frame currently available on the market
D. Prioritizing cosmetic aesthetic choices over clinical postural support features
Answer: B
,For progressive neurological conditions, the ATP must anticipate functional decline over time.
Evaluating anticipated fatigue patterns and progressive support needs ensures that the
prescribed mobility system can be modified or upgraded rather than replaced prematurely.
3. A client presents with a fixed right pelvic obliquity where the right pelvis is significantly
lower than the left. When configuring a custom seating system, how should the ATP
address this postural asymmetry?
A. Build up the seating surface under the right ischial tuberosity to force the pelvis level
immediately
B. Accommodate the fixed asymmetry by providing asymmetrical build-ups under the higher
side while offloading or redistributing pressure evenly under the lower side to prevent pressure
injuries
C. Force the spine into a rigid straight alignment using aggressive lateral thoracic supports
D. Ignore the obliquity and provide a standard symmetric flat cushion
Answer: B
A fixed skeletal deformity cannot be corrected by force without causing pain or tissue damage.
It must be accommodated by building up support under the low side or building down under
the high side while protecting pressure points from excessive shear and peak pressures.
4. A Medicare beneficiary requires a Group 3 power wheelchair with power tilt and power
recline functions. Which of the following documentation requirements is strictly mandated
by regulatory guidelines to justify the medical necessity of these power functions?
A. Client preference for comfort while watching television at home
B. Documented inability to perform functional weight shifts independently to manage pressure
redistribution, coupled with measurable skin integrity risks
C. A verbal statement from the family caregiver requesting automated features for easier vehicle
loading
D. Proof that the client owns a home compatible with an oversized wheelchair base
Answer: B
Power tilt and recline functions are funded based on documented medical necessity, primarily
the client’s inability to perform independent weight shifts to manage pressure sores or manage
orthostatic hypotension, autonomic dysreflexia, or tone.
,5. Which of the following frame materials offers the highest stiffness-to-weight ratio and
superior vibration dampening for an active user requiring an ultra-lightweight manual
wheelchair?
A. Standard structural carbon steel
B. Commercial-grade aluminum alloy 6061
C. Titanium alloy
D. Cast iron
Answer: C
Titanium alloy provides an exceptional strength-to-weight ratio, excellent corrosion
resistance, and natural vibration-dampening characteristics that reduce repetitive stress on the
upper extremities of active manual wheelchair users.
6. A client with severe spastic cerebral palsy exhibits strong extensor thrusts that
frequently dislodge them from their wheelchair seating system. Which component is most
critical for managing this extensor tone?
A. A loose thoracic chest strap placed loosely across the upper chest
B. A 4-point pelvic positioning belt combined with a properly angled dynamic or static seating
system that controls hip and knee angles
C. A simple lap tray attached to armrests without torso support
D. Removing all footplate supports to allow free lower extremity extension
Answer: B
Management of strong extensor thrusts requires a multi-point containment strategy, starting
with a secure 4-point pelvic belt that captures the anterior superior iliac spines, combined with
supportive positioning at the knees and feet to break up the extensor synergy pattern.
7. When measuring a client for a custom wheelchair seating cushion, the ATP notes that
the client’s actual seated hip width measures 16 inches across the widest point of the
trochanters. What is the standard recommended seat cushion width to ensure proper
pressure distribution without lateral instability?
A. 14 inches
B. 16 inches
, C. 20 inches
D. 22 inches
Answer: B
The cushion width should match the client's actual hip width (16 inches) to provide adequate
lateral support and prevent sliding or listing. A cushion that is too wide promotes leaning,
while one that is too narrow creates excessive pressure on the trochanters.
8. An aging client with muscular dystrophy experiences progressive upper extremity
weakness, making manual wheelchair propulsion increasingly difficult. The funding source
requires a formal justification for transitioning from a manual to a power wheelchair.
Which factor provides the strongest clinical justification?
A. Desire to travel internationally on commercial airlines
B. Preservation of residual functional energy for activities of daily living and maintenance of
independent community mobility
C. Aesthetic preference for motorized equipment
D. Availability of garage storage space
Answer: B
Demonstrating that independent manual propulsion leads to exhaustion and compromises the
client's ability to perform activities of daily living justifies transitioning to a power mobility
device to preserve energy and sustain independence.
9. A client utilizes a power wheelchair equipped with proportional mini-proportional
specialty controls operated via chin drive due to high cervical spinal cord injury. During
routine maintenance, the client reports intermittent jerky movements and loss of tracking.
What is the most appropriate initial troubleshooting step?
A. Immediately replace the entire power wheelchair electronics module and drive motors
B. Check all physical mounting hardware for stability, inspect wiring harness connections for
wear, and recalibrate the neutral deadband and throw settings
C. Increase the maximum forward speed parameter to 10 miles per hour
D. Disconnect all backup safety switches permanently
Answer: B
