Sit-to-stand transfers are frequently performed, and transfers have been associated with fall risk among people with multiple sclerosis (PwMS). There is limited research regarding the validity of sit-to-stand tests (STSs) in PwMS. The purpose of this study was to investigate the concurrent, divergent, and discriminant validity and sensitivity to change of the 5 and 10 STSs.
A repeated-measurement design was used, with data collected before and directly after a 7-week intervention, as well as prospectively reported near-fall incidents and falls during a 14-week period. One hundred two PwMS with a limited (≤200 m) but retained (≥20 m) walking ability were identified by physiotherapists at outpatient rehabilitation centres in 5 Swedish County Council areas and invited to participate in an intervention study. Of the 52 participants agreeing to participate and fulfilling the inclusion criteria, 47 managed the tests at baseline, and 39 of these returned complete fall diaries. The main outcomes were the Berg Balance Scale (BBS), Timed Up and Go test (TUG), 10-m walk test, 2-min walk test, Fatigue Scale for Motor and Cognitive Function, falls, near-fall incidents, and use of walking aids.
Correlations in the total sample were above .60 between the STSs and BBS, TUG, 10-m walk test, and 2-min walk test and above .50 between the STSs and total number of falls. Both tests discriminated between those who did and did not use walking aids for the TUG, but not between fallers and nonfallers. There were no significant correlations between the STSs and number of falls or near-fall incidents. The STSs did not differentiate between participants with changed and unchanged results on the BBS.
The 5 and 10 STSs are valid in PwMS with an Expanded Disability Status Scale score ≤6.0 but do not identify fallers and have limited ability to detect change. Copyright © 2017 John Wiley & Sons, Ltd.
从坐到站的转移动作经常发生，且这种转移与多发性硬化症患者（PwMS）的跌倒风险相关。关于PwMS中从坐到站测试（STS）有效性的研究有限。本研究的目的是调查5次和10次STS的同时效度、区分效度、判别效度以及对变化的敏感性。
采用重复测量设计，在为期7周的干预前后直接收集数据，以及前瞻性报告14周期间的近跌倒事件和跌倒情况。瑞典5个郡议会地区的门诊康复中心的物理治疗师识别出102名行走能力有限（≤200米）但仍保留（≥20米）的PwMS，并邀请他们参加一项干预研究。在同意参与并符合纳入标准的52名参与者中，47名在基线时完成了测试，其中39名返回了完整的跌倒日记。主要结局指标包括伯格平衡量表（BBS）、计时起立行走测试（TUG）、10米步行测试、2分钟步行测试、运动和认知功能疲劳量表、跌倒、近跌倒事件以及助行器的使用情况。
在总样本中，STS与BBS、TUG、10米步行测试和2分钟步行测试之间的相关性高于0.60，与跌倒总数之间的相关性高于0.50。两项测试在TUG中能区分使用和未使用助行器的人，但在跌倒者和未跌倒者之间无区分能力。STS与跌倒次数或近跌倒事件之间无显著相关性。STS在BBS结果有变化和无变化的参与者之间无差异。
5次和10次STS在扩展残疾状态量表评分≤6.0的PwMS中有效，但无法识别跌倒者，且检测变化的能力有限。版权所有©2017约翰威立父子有限公司。
