RaceRunning enables athletes with limited or no walking ability to propel themselves independently using a three-wheeled frame that has a saddle, handle bars and a chest plate. For RaceRunning to be included as a para athletics event, an evidence-based classification system is required. This study assessed the impact of trunk control and lower limb impairment measures on RaceRunning performance and evaluated whether cluster analysis of these impairment measures produces a valid classification structure for RaceRunning. The Trunk Control Measurement Scale (TCMS), Selective Control Assessment of the Lower Extremity (SCALE), the Australian Spasticity Assessment Scale (ASAS), and knee extension were recorded for 26 RaceRunning athletes. Thirteen male and 13 female athletes aged 24 (SD = 7) years participated. All impairment measures were significantly correlated with performance (rho = 0.55-0.74). Using ASAS, SCALE, TCMS and knee extension as cluster variables in a two-step cluster analysis resulted in two clusters of athletes. Race speed and the impairment measures were significantly different between the clusters (p < 0.001). The findings of this study provide evidence for the utility of the selected impairment measures in an evidence-based classification system for RaceRunning athletes.
竞速轮椅运动使那些行动能力有限或无法行走的运动员能够使用带有鞍座、把手和胸板的三轮框架独立推进自己。要将竞速轮椅运动纳入残奥运动项目，就需要一个基于证据的分类系统。本研究评估了躯干控制和下肢损伤测量对竞速轮椅运动表现的影响，并评估了这些损伤测量的聚类分析是否能为竞速轮椅运动产生有效的分类结构。记录了 26 名竞速轮椅运动员的躯干控制测量量表（TCMS）、下肢选择性控制评估（SCALE）、澳大利亚痉挛评估量表（ASAS）和膝关节伸展情况。13 名男性和 13 名女性运动员的年龄为 24 岁（SD=7 岁）。所有损伤测量均与表现显著相关（rho=0.55-0.74）。使用 ASAS、SCALE、TCMS 和膝关节伸展作为两步聚类分析的聚类变量，结果产生了两个运动员聚类。两个聚类之间的竞赛速度和损伤测量指标存在显著差异（p<0.001）。本研究的结果为基于证据的竞速轮椅运动员分类系统中选择的损伤测量的实用性提供了证据。
