Objective: The primary objective of this study was to test the hypotheses that a wheelie training method that begins in a high-rolling-resistance (RR) setting (1) improves the success rate and (2) reduces the training time. Our secondary objectives were to assess the effects of other factors (e.g.

The secondary hypotheses were that walking with a SAP decreases the heel-strike transient force between the ground and the foot and increases function as measured by walking velocity and subjective assessments. Seven people with unilateral trans-tibial amputations walked at self-selected speeds without and with a SAP.

Article Synopsis
- The study aimed to evaluate how increased rolling resistance (RR) affects rear-wheel displacement and perceived difficulty during stationary wheelchair wheelies among 20 participants.
- Participants performed wheelies on different surfaces (tile, foam, and blocks) while measuring wheel displacement and perceived difficulty.
- Results showed that higher RR significantly decreased rear-wheel displacement and made the wheelies appear more challenging, particularly on tile compared to foam and blocks, emphasizing the importance of these findings in training wheelchair users for advanced skills.
