Read the first 7 Manual & Power Wheelchair Selection flashcards as text

  1. A power wheelchair user complains that the chair drifts to one side during straight-line driving. What is the most likely adjustment needed?

    Answer: Perform motor balance or joystick calibration

    Drifting during straight-line travel typically indicates unequal motor output or a joystick calibration issue, both corrected through the chair's programming interface.

  2. Which manual wheelchair configuration is most appropriate for a client who needs to self-propel but has significantly different leg lengths?

    Answer: Hemi-height frame with lower seat-to-floor height

    A hemi-height (low seat-to-floor) frame lets a client with shorter or weaker legs use the floor for propulsion, also accommodating leg-length discrepancies with appropriate footrest adjustment.

  3. According to RESNA and wheelchair standards, what static stability test determines a manual wheelchair's tipping resistance?

    Answer: ISO 7176-1 static stability test

    ISO 7176-1 specifies the static stability test procedure, measuring the angle at which a loaded wheelchair tips forward, rearward, and laterally.

  4. A client with spastic diplegia due to cerebral palsy requires a power wheelchair. Which seating component is MOST critical to control lower extremity positioning?

    Answer: Solid seat insert with contoured cushion

    A solid seat insert with a contoured pressure-relieving cushion provides stable, symmetrical hip positioning that reduces the influence of spasticity on lower extremity posture.

  5. Which HCPCS code group covers a power wheelchair with a Group 3 controller (complex rehab technology)?

    Answer: K0835–K0864

    HCPCS codes K0835–K0864 cover Group 3 power wheelchairs, which include complex rehab power bases with advanced programming capabilities.

  6. A 70-year-old client with severe COPD and limited upper extremity strength needs indoor mobility. Which device type is MOST appropriate?

    Answer: Standard power wheelchair with proportional joystick

    A standard power wheelchair with a proportional joystick requires minimal upper extremity effort, accommodating the client's strength limitations while providing independent indoor mobility.

  7. What is the functional significance of anti-tippers on a manual wheelchair?

    Answer: They limit rearward tipping when ascending inclines or performing wheelies

    Anti-tippers are small rear extensions that contact the ground if the chair tilts too far back, preventing a full backward fall especially on inclines or during sudden acceleration.
