What is the appropriate way to ascend a curb with a forward approach when using a wheelchair

What is the appropriate way to ascend a curb with a backward approach when using a wheelchair
- position the pt facing away from the curb
- lift and roll the back wheels backward up the curb
- continue to roll backwards until the front wheels are in contact with the ground
What is the appropriate way to descend a curb with a forward approach when using a wheelchair
- Tip the chair back so the front wheels are elevated

- gently lower the front wheels down
What is the appropriate way to descend a curb with a backward approach when using a wheelchair
- position the patient away from the curb
- move the wc backwards and slowly lower the rear wheels to the ground
