AIMS
i) to compare 30-s sit-to-stand (STS) test repetitions and power between older adults with and without Parkinson's disease (PD) and ii) to evaluate the relationship of STS repetitions and power with functional measures in older people with PD.
METHODS
STS repetitions and power (Alcazar's equation) during the 30-s STS test were assessed in forty-six age- and sex-matched older adults with and without PD. Functional measures included habitual (HGS) and maximum gait speed (MGS), timed-up-and-go (TUG) test and the Mini-Balance Evaluation System Test (Mini-BEST). PD-specific tests were as follows: the motor subscale of the Unified Parkinson's Disease Rating Scale (UPDRS-III), quality of life [Parkinson's Disease Questionnaire (PDQ-39)], perceived freezing of gait (FOG questionnaire), and fear of falling [Falls Efficacy Scale (FES)]. T scores, repeated measures ANOVA and linear regression analyses were used.
RESULTS
T scores for older adults with PD were - 2.7 ± 4.5 for STS repetitions, -5.2 ± 4.2 for absolute STS power, and - 3.1 ± 4.6 for relative STS power compared to older adults without PD. T scores for absolute STS power were lower than T scores for STS repetitions (p < 0.001) and relative STS power (p < 0.001). Both absolute and relative STS power and STS repetitions showed similar correlations with functional measures (r = 0.44 to 0.59; both p < 0.05). Relative STS power (r = -0.55; p < 0.05) and STS repetitions (r = -0.47 to -0.55; p < 0.05) but not absolute STS power were correlated to PD-specific tests.
CONCLUSIONS
STS repetitions and power values estimated through the 30-s STS test were lower in older people with PD than without PD. Overall, STS power measures were similarly associated with functional performance as STS repetitions, indicating these power equations can be implemented when assessing lower extremity function in older people with PD.
目的
i）比较患有和不患有帕金森病（PD）的老年人在 30 秒坐站（STS）测试中的重复次数和功率，ii）评估 STS 重复次数和功率与 PD 老年人功能测量的关系。
方法
在 46 名年龄和性别匹配的患有和不患有 PD 的老年人中评估 30 秒 STS 测试中的 STS 重复次数和功率（Alcazar 方程）。功能测量包括习惯性握力（HGS）和最大步态速度（MGS）、计时起立行走（TUG）测试和 Mini-Balance Evaluation System Test（Mini-BEST）。PD 特异性测试如下：统一帕金森病评定量表（UPDRS-III）的运动子量表、生活质量[帕金森病问卷（PDQ-39）]、感知冻结步态（FOG 问卷）和跌倒恐惧[跌倒效能量表（FES）]。使用 T 分数、重复测量方差分析和线性回归分析。
结果
患有 PD 的老年人的 T 分数为 STS 重复次数为-2.7±4.5，绝对 STS 功率为-5.2±4.2，相对 STS 功率为-3.1±4.6，与不患有 PD 的老年人相比。绝对 STS 功率的 T 分数低于 STS 重复次数（p<0.001）和相对 STS 功率（p<0.001）的 T 分数。绝对和相对 STS 功率和 STS 重复次数与功能测量具有相似的相关性（r=0.44 至 0.59；均 p<0.05）。相对 STS 功率（r=-0.55；p<0.05）和 STS 重复次数（r=-0.47 至-0.55；p<0.05）与 PD 特异性测试相关，但绝对 STS 功率与 PD 特异性测试无关。
结论
患有 PD 的老年人在 30 秒 STS 测试中的 STS 重复次数和功率值低于不患有 PD 的老年人。总体而言，STS 功率测量与功能表现的相关性与 STS 重复次数相似，表明这些功率方程可用于评估 PD 老年人下肢功能。
