CRA Adaptive Sports Equipment 2 — Questions and Answers
Question 1: Which feature is most important when selecting a wheelchair for wheelchair basketball?
- High seat height for better court visibility
- Angled (cambered) wheels for stability and maneuverability (Correct answer)
- Removable armrests for easier transfers
- Padded headrest for neck support
Correct answer: Angled (cambered) wheels for stability and maneuverability
Cambered wheels on sport wheelchairs lower the center of gravity and increase lateral stability during quick direction changes on the court.
Question 2: A participant with a below-elbow amputation wants to play tennis. Which adaptive device is most appropriate?
- A universal cuff attached to the racket handle
- A prosthetic terminal device designed to grip a racket (Correct answer)
- A body-powered hook prosthesis with no modifications
- Taping the racket directly to the residual limb
Correct answer: A prosthetic terminal device designed to grip a racket
A prosthetic terminal device specifically designed for racket sports allows secure grip and effective swing mechanics for below-elbow amputees.
Question 3: What is the primary purpose of a beep baseball used in adaptive sports?
- To make the ball easier to catch due to its larger size
- To allow players with visual impairments to locate the ball by sound (Correct answer)
- To slow down the pitch for players with cognitive disabilities
- To reduce hand impact for players with upper limb differences
Correct answer: To allow players with visual impairments to locate the ball by sound
Beep baseballs emit an audible beeping sound so that participants who are blind or visually impaired can track and field the ball.
Question 4: When fitting a hand cycle for a participant with a spinal cord injury, what is the first measurement the recreation aide should take?
- Shoulder width
- Trunk height while seated
- Arm length (reach) (Correct answer)
- Grip strength rating
Correct answer: Arm length (reach)
Arm length determines the appropriate crank radius and handlebar distance, ensuring efficient power transfer and preventing shoulder overuse injuries.
Question 5: Which adaptive archery device assists a participant who has limited hand strength or cannot grip a bow?
- A mouth tab release
- A wrist release aid or mechanical trigger release (Correct answer)
- A longer draw-weight bow
- A compound bow with a drop-away rest
Correct answer: A wrist release aid or mechanical trigger release
A wrist or mechanical trigger release allows archers with limited grip strength to draw and release the bowstring without relying on finger strength.
Question 6: A sit-ski differs from a mono-ski primarily in that the sit-ski:
- Is designed for higher speeds on groomed runs
- Requires no outriggers and is pulled by an instructor
- Has a lower, more reclined bucket seat and is typically tethered for beginners (Correct answer)
- Is used exclusively by upper-limb amputees
Correct answer: Has a lower, more reclined bucket seat and is typically tethered for beginners
Sit-skis have a lower seat and rely on an instructor tether for control, making them suitable for beginners or those with very limited trunk control, unlike the more independent mono-ski.
Question 7: What safety check should a recreation aide perform on a sport wheelchair before each use?
- Inspect the seat cushion color for fading
- Verify wheel locks, tire pressure, and anti-tip device function (Correct answer)
- Confirm the chair's weight capacity label is visible
- Check that the chair serial number matches documentation
Correct answer: Verify wheel locks, tire pressure, and anti-tip device function
Functional checks of wheel locks, tire pressure, and anti-tip devices are critical pre-use safety steps to prevent tip-overs and loss of control during activity.
