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 ( > 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.
由于实际应用中存在固有的变化，在生态环境下测量运动轮椅的推进性能仍然很复杂。本研究旨在为一种用于在生态环境下测量推进力的仪器化轮椅开发验证方案。将该轮椅的精度与Lode Esseda滚筒测力计（测量左右手施加力的黄金标准）的精度进行比较。在一辆多功能运动轮椅上以三种速度（1、2和3米/秒）进行了测试。结果表明，两个系统之间存在很强的相关性，重复测量方差分析测试（>0.05）和均方根误差（RMSE<5%）证实了这一点。布兰德-奥特曼图显示，尽管在高速时观察到差异，但仍具有良好的一致性，这可能是由于机械限制。所提出的方案验证了仪器化轮椅，并强调了多速度评估对于确保在生态环境下进行有效测量的重要性。
