To determine the relationship between mobility performance measures and Wheelchair Skill Test (WST) scores and to establish the test-retest and inter-rater reliability of these measures.
Forty patients with spinal cord injury participated in this study. Subjects performed the Wheelchair Skill Test and mobility performance tests: maximal velocity (Vmax), spontaneous velocity (Vspont) and a 10-m back and forth slalom (Stime). Eighteen patients with spinal cord injury participated in a second testing session to evaluate test-retest reliability and, among these patients, 8 participated in a third testing session to evaluate inter-rater reliability.
Spearman's correlation coefficients calculated between WST and Vmax, Vspont and Stime were high and significant (p < 0.05). The intraclass correlation coefficients (ICC (2.1)) evaluating test-retest reliability for Vmax, Vspont and Stime were 0.94, 0.84 and 0.88, respectively. The ICC evaluating inter-rater reliability for Vmax, Vspont and Stime were 0.92, 0.92 and 0.95, respectively. Reliability results were confirmed by Bland-Altman plots.
Vmax and Stime could be used to evaluate wheelchair skills and to create a new scale, whereas Vspont is the least appropriate of these measurements to describe wheelchair skills.
确定移动性能测量与轮椅技能测试（WST）评分之间的关系，并确定这些测量的测试-重测和组内信度。
40 名脊髓损伤患者参与了这项研究。受试者进行了轮椅技能测试和移动性能测试：最大速度（Vmax）、自发速度（Vspont）和 10 米往返穿梭（Stime）。18 名脊髓损伤患者参加了第二次测试，以评估测试-重测信度，其中 8 名患者参加了第三次测试，以评估组内信度。
WST 与 Vmax、Vspont 和 Stime 之间的 Spearman 相关系数高且显著（p<0.05）。评估 Vmax、Vspont 和 Stime 的重测信度的组内相关系数（ICC（2.1））分别为 0.94、0.84 和 0.88。评估 Vmax、Vspont 和 Stime 的组内信度的 ICC 分别为 0.92、0.92 和 0.95。可靠性结果通过 Bland-Altman 图得到证实。
Vmax 和 Stime 可用于评估轮椅技能并创建新的量表，而 Vspont 是描述轮椅技能最不合适的测量方法之一。
