Context/Objectives: Various clinical application of the five times sit-to-stand test (FTSST), with or without hands, may confound the outcomes to determine the lower limb functions and mobility of individuals with spinal cord injury (SCI). This study assessed the concurrent validity of the FTSST in ambulatory individuals with SCI who completed the test with or without hands as verified using standard measures for lower extremity motor scores (LEMS) and functional mobility necessary for independence and safety of these individuals.

Design: Cross-sectional study.

Setting: Tertiary rehabilitation centers and community hospitals.

Participants: Fifty-six ambulatory individuals with motor incomplete SCI who were able to walk independently with or without a walking device over at least 10 m.

Outcome Measures: Time to complete the FTSST with or without hands according to individuals’ abilities, LEMS, and functional mobility.

Results: Time to complete the FTSST showed moderate-to-strong correlation with the LEMS scores and all functional mobility tests (ρ = –0.38 to –0.71, P < 0.05), but only in those who performed the test without hands. By contrast, data of those who completed the FTSST with hands were significantly correlated only with the ankle muscle strength and the functional mobility measures that allow upper limb contribution in the tests (ρ = –0.40 to 0.52, P < 0.05).

Conclusion: Upper limb involvement could confound the outcomes of the FTSST. The present findings suggest the use of FTSST without hands to determine the lower limb functions of ambulatory individuals with SCI.

背景/目的：五次坐或站手测试（FTSST）的各种临床应用，无论有无手，都可能混淆结果，以确定脊髓损伤（SCI）患者的下肢功能和活动能力。这项研究评估了FTSST在患有SCI的非卧床患者中的并发有效性，该患者已通过使用标准方法测量了这些患者的下肢运动评分（LEMS）和这些患者独立性和安全性所必需的功能性活动，从而完成了手或不手的测试。

设计：横断面研究。

地点：第三级康复中心和社区医院。

参与者： 56名运动不完全SCI的步行者，他们能够在至少10 m的有或没有步行装置的情况下独立行走。

成果衡量：根据个人的能力，LEMS和功能流动性，手动或不手动完成FTSST的时间。

结果：完成FTSST的时间与LEMS评分和所有功能迁移测试之间呈中等至强相关性（ρ  = –0.38至–0.71，P <0.05），但仅在那些没有双手进行测试的人中。相比之下，用手完成FTSST的人的数据仅与踝部肌肉的力量和允许上肢参与测试的功能活动性指标显着相关（ρ  = –0.40至0.52，P <0.05）。

结论：上肢受累可能混淆FTSST的结果。目前的发现表明，不用手动FTSST即可确定患有SCI的卧床患者的下肢功能。
