Abstract

Measuring the propulsion performance of sport wheelchairs in ecological conditions remains complex due to variations inherent in real-world practice. This study aims to develop a validation protocol for an instrumented wheel designed to measure propulsion power under ecological conditions. The wheel's precision was compared to that of the Lode Esseda roller ergometer, the gold standard for measuring the force exerted on both the left and right hands. Tests were conducted at three speeds (1, 2, and 3 m/s) on a multisport wheelchair. Results show a strong correlation between the two systems, confirmed by a repeated measures ANOVA test (p > 0.05) and a root mean square error (RMSE < 5%). Bland-Altman plots reveal good agreement despite discrepancies observed at high speeds, potentially due to mechanical limits. The proposed protocol validates the instrumented wheel and highlights the importance of multi-speed evaluation to ensure valid measurements in ecological conditions.

一种仪器轮的验证方案：与双滚轮轮辋轮椅测力仪的比较。

由于现实世界实践中固有的变化，测量生态条件下运动轮椅的推进性能仍然很复杂。本研究旨在开发一种用于测量生态条件下推进功率的仪表轮的验证方案。这个轮子的精度与Lode Esseda滚轮测力仪进行了比较，后者是测量左手和右手所受力的黄金标准。在多运动轮椅上以三种速度（1、2和3米/秒）进行了测试。通过重复测量方差分析（p < 0.05）和均方根误差（RMSE < 5%）证实，两个系统之间存在很强的相关性。布兰德-奥特曼图显示了良好的一致性，尽管在高速下观察到差异，可能是由于机械限制。提出的方案验证了仪器轮，并强调了多转速评估的重要性，以确保在生态条件下测量的有效性。
