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/目标： 5 次坐姿站姿测试 (FTSST) 的各种临床应用，无论是否有手，都可能会混淆确定脊髓损伤 (SCI) 患者下肢功能和活动能力的结果。本研究评估了 FTSST 在 SCI 患者中的同时有效性，他们使用或不使用双手完成了测试，并使用这些个体的独立性和安全性所必需的下肢运动评分 (LEMS) 和功能移动性的标准测量来验证。

设计：横断面研究。

地点：三级康复中心和社区医院。

参与者： 56 名运动不完全 SCI 的行走个体，他们能够在有或没有行走装置的情况下独立行走至少 10 m。

结果测量：根据个人的能力、LEMS 和功能移动性，完成有或没有手的 FTSST 的时间。

结果：完成 FTSST 的时间与 LEMS 分数和所有功能移动性测试显示出中度至强相关性（ρ  = –0.38 到 –0.71，P < 0.05），但仅在那些不用手进行测试的人中。相比之下，用手完成 FTSST 的人的数据仅与脚踝肌肉力量和允许上肢在测试中贡献的功能活动度测量显着相关（ρ  = –0.40 至 0.52，P < 0.05）。

结论：上肢受累可能会混淆 FTSST 的结果。目前的研究结果表明，在没有手的情况下使用 FTSST 来确定 SCI 患者的下肢功能。
