2. Fig 1
In the approach phase (A), the wheelchair user approached the 15cm-high curb squarely, rapidly, and with the hands ready to apply forward forces on the hand rims at the appropriate moment. In the caster-pop phase (B), the wheelchair user accelerated the rear wheels, causing the casters to lift from the surface. In the rear-wheel-ascent phase (C), the wheelchair user leaned forward and applied another push to the hand-rims. Once on the curb (D), the wheelchair user sat upright. Throughout the skill, the single spotter held a spotter strap loosely in the right hand and held the left hand near the wheelchair user's shoulder.

Intervention versus control groups with respect to training time, success rate, spotter interventions, and perceived difficulty. Mean + SD values are shown. Only the training time difference was statistically significant (P=0.042).

4. Fig 3
The wheelchair's casters failed to clear the curb during the caster-pop phase, causing the wheelchair to stop abruptly and tip forward. The rear spotter held a spotter strap to prevent a full rear tip. The forward spotter prevented a full forward tip or the wheelchair occupant falling from the wheelchair.

5. Fig 4
The wheelchair struck the curb with the right rear wheel first. When this wheel ascended the curb before the left one, the spotter was required to intervene to prevent a full lateral tip.
