CMC Mobility Assessments & Evaluations 2 — Questions and Answers
Question 1: During a home assessment, a CMC discovers that a client's bathroom doorway is 28 inches wide. What is the minimum ADA-recommended clear width for wheelchair passage?
- 28 inches
- 32 inches
- 36 inches (Correct answer)
- 42 inches
Correct answer: 36 inches
ADA guidelines recommend a minimum clear width of 36 inches for wheelchair-accessible doorways, though 32 inches is the absolute minimum in some residential contexts.
Question 2: When evaluating a client for a power wheelchair, which assessment tool is most appropriate for measuring upper extremity strength and control?
- Berg Balance Scale
- Manual Muscle Testing (MMT) (Correct answer)
- Timed Up and Go (TUG)
- Functional Independence Measure (FIM)
Correct answer: Manual Muscle Testing (MMT)
Manual Muscle Testing (MMT) directly assesses muscle strength grades, which is essential for determining if a client can operate joystick or alternative drive controls.
Question 3: A client with ALS reports progressive upper limb weakness. Which drive control alternative should the CMC prioritize evaluating first?
- Foot controls
- Head array (Correct answer)
- Chin control
- Sip-and-puff
Correct answer: Head array
Head array controls are often the first alternative considered for ALS clients because head and neck function is typically preserved longer than limb or oral motor function.
Question 4: Which of the following is the PRIMARY purpose of a seating simulation during a mobility assessment?
- To determine insurance coverage eligibility
- To trial positioning before equipment is ordered (Correct answer)
- To document the client's diagnosis
- To measure the room dimensions
Correct answer: To trial positioning before equipment is ordered
Seating simulation allows the clinician to trial various positioning supports and configurations before finalizing an equipment order.
Question 5: A CMC is evaluating a client with spasticity. Which measurement is most critical to obtain before recommending a rigid seating system?
- Skin temperature
- Passive range of motion (PROM) (Correct answer)
- Heart rate variability
- Visual acuity
Correct answer: Passive range of motion (PROM)
Passive range of motion measurements determine whether a client can be accommodated in a rigid seat without causing pain or injury from fixed joint limitations.
Question 6: During an evaluation, a client demonstrates a posterior pelvic tilt that cannot be corrected passively. What type of seat surface is most appropriate?
- Flat seat insert
- Solid seat with posterior tilt adjustment (Correct answer)
- Sling upholstery
- Anterior seat wedge
Correct answer: Solid seat with posterior tilt adjustment
A solid seat with posterior tilt capability accommodates a fixed posterior tilt, providing stable support without forcing the pelvis into a painful corrected position.
Question 7: Which standardized outcome measure is specifically designed to assess wheeled mobility performance in community settings?
- Wheelchair Skills Test (WST) (Correct answer)
- Modified Ashworth Scale
- Barthel Index
- ASIA Impairment Scale
Correct answer: Wheelchair Skills Test (WST)
The Wheelchair Skills Test (WST) evaluates a user's ability to perform wheelchair skills in varied environments including community-level tasks.
