What is the correct sequence for ascending a curb with a backward approach?

• A. Stand on the upper surface; Lift and roll rear wheels backward up curb; Roll backwards until casters are in contact with the upper surface.
• B. Stand on the lower surface; Roll forward up the curb until the front wheels clear the curb.
• C. Position casters near the edge; Tilt forward and push the chair forward onto the curb.
• D. Stand on the upper surface; Tilt back and push the chair backward off the curb.

Answer: (A)

When ascending a curb with a backward approach, the goal is to bring the chair onto the higher surface in a controlled, stable way by lifting the rear wheels first and then guiding the chair onto the curb from behind. This sequence starts with you standing on the upper surface so you can use your body weight and arm strength to lift and roll the rear wheels up onto the curb. Once the rear wheels are on the curb, you back the chair onto the upper surface so the front casters are the last to contact, ensuring the chair lands securely with all wheels on the higher surface. This method reduces the risk of tipping forward and gives you better control during the transition.

The other options describe approaches that either push the chair forward onto the curb or involve standing on the lower surface and moving in a way that increases tipping risk or instability, making them less safe or practical in a standard curb ascent.
