The 30-second Chair Stand Test (30s-CST) and Modified Four Square Step Test (mFSST) are used to determine the functional status of individuals with multiple sclerosis (MS). No other studies have demonstrated the reliability and validity of the 30s-CST and mFSST.
To identify the test-retest reliability, concurrent validity and the known-group validity of the 30s-CST and mFSST in persons with MS.
A total of 64 persons with MS were enrolled. 30s-CST, mFSST, Timed Up and Go Test (TUG) and Five Times Sit to Stand (FTST) tests were performed. 30s-CST and mFSST were conducted again one-hour later.
The mean age of the persons with MS were 37.9±11.3 years. The test-retest reliability of the 30s-CST and mFSST were excellent (ICC = 0.974, 95%CI: 0.95-0.98; ICC = 0.992, 95%CI: 0.98-0.99). The 30s-CST was strongly correlated with FTST and TUG (r = -0.871, p = 0.0001; r = -0.741,p = 0.0001). There was a strong relationship between mFSST with TUG and FTST (r = 0.781,p = 0.0001;r = 0.788,p = 0.0001). The SEM and MDC values of the 30s-CST and mFSST were 0.41/1.13 and 0.34/0.94, respectively. Besides, there were significant differences between the persons with or without fall history in 30s-CST (MD: 1.66, CI: 0.27 to 3.05, p = .019) and mFSST CST (MD:-2.70, CI: -4.73 to -0.67, p = .010) performances.
The 30s-CST and mFSST are both valid and reliable in mildly-disabled individuals with MS.
30 秒椅站测试（30s-CST）和改良四方步测试（mFSST）用于确定多发性硬化症（MS）患者的功能状态。没有其他研究表明 30s-CST 和 mFSST 的可靠性和有效性。
确定 30s-CST 和 mFSST 在 MS 患者中的重测信度、同时效度和已知组效度。
共纳入 64 名 MS 患者。进行 30s-CST、mFSST、计时起立行走测试（TUG）和五次坐立测试（FTST）。1 小时后再次进行 30s-CST 和 mFSST。
MS 患者的平均年龄为 37.9±11.3 岁。30s-CST 和 mFSST 的重测信度均为优（ICC=0.974，95%CI：0.95-0.98；ICC=0.992，95%CI：0.98-0.99）。30s-CST 与 FTST 和 TUG 呈强相关（r=-0.871，p=0.0001；r=-0.741，p=0.0001）。mFSST 与 TUG 和 FTST 之间存在强相关性（r=0.781，p=0.0001；r=0.788，p=0.0001）。30s-CST 和 mFSST 的 SEM 和 MDC 值分别为 0.41/1.13 和 0.34/0.94。此外，在 30s-CST（MD：1.66，CI：0.27 至 3.05，p=0.019）和 mFSST CST（MD：-2.70，CI：-4.73 至-0.67，p=0.010）表现方面，有跌倒史与无跌倒史的患者之间存在显著差异。
30s-CST 和 mFSST 在轻度残疾的 MS 患者中均具有有效性和可靠性。
