“计时起床和走”（TUG）是一种广泛用于老年人和神经系统人群（包括帕金森病患者）身体功能的测量方法。当使用惯性传感器测量系统（仪表化TUG [iTUG]）时，可以单独测量iTUG的各个部件和主干的运动学，这可能提供相关的附加信息。本研究的目的是确定帕金森病患者iTUG的评分内、评分间和重测信度。纳入了28名年龄在50岁或以上的PD患者。对于iTUG， dynapport Hybrid （McRoberts, the Hague, the Netherlands）被穿在下背部。该装置以100个样本/秒的速率在三个方向上测量加速度和角速度。患者连续2天进行5次iTUG检查。采用同一评价者在同一天的重复测量来计算评价者内部的信度。采用不同评价者在同一天的重复测量来计算评价者内部和评价者之间的信度。采用同一评价者在不同日期的重复测量来计算重测信度。19例（15%）的ICC值≥0.9被认为是极好的信度。64个（49%）的ICC值≥0.70和< 0.90，信度较好。31个（24%）的ICC值≥0.50和< 0.70，信度中等。16个ICC值(12%)≥0.30和< 0.50表明信度较差。2个ICT值(2%)< 0.30，表明可靠性很差。总之，在帕金森病患者中，仪器化TUG （iTUG）各部件的评分内、评分间和重测信度在总持续时间和转弯持续时间方面从优秀到优秀，在次持续时间和SiSt和StSi的运动学方面从优秀到低。对仪器化TUG运动的全自动分析结果表明，可以确定几个可靠的TUG参数，为在临床实践中更精确、定量地使用TUG测试提供基础。
The “Timed Up and Go” (TUG) is a widely used measure of physical functioning in older people and in neurological populations, including Parkinson’s Disease. When using an inertial sensor measurement system (instrumented TUG [iTUG]), the individual components of the iTUG and the trunk kinematics can be measured separately, which may provide relevant additional information. The aim of this study was to determine intra-rater, inter-rater and test-retest reliability of the iTUG in patients with Parkinson’s Disease. Twenty eight PD patients, aged 50 years or older, were included. For the iTUG the DynaPort Hybrid (McRoberts, The Hague, The Netherlands) was worn at the lower back. The device measured acceleration and angular velocity in three directions at a rate of 100 samples/s. Patients performed the iTUG five times on two consecutive days. Repeated measurements by the same rater on the same day were used to calculate intra-rater reliability. Repeated measurements by different raters on the same day were used to calculate intra-rater and inter-rater reliability. Repeated measurements by the same rater on different days were used to calculate test-retest reliability. Nineteen ICC values (15%) were ≥ 0.9 which is considered as excellent reliability. Sixty four ICC values (49%) were ≥ 0.70 and < 0.90 which is considered as good reliability. Thirty one ICC values (24%) were ≥ 0.50 and < 0.70, indicating moderate reliability. Sixteen ICC values (12%) were ≥ 0.30 and < 0.50 indicating poor reliability. Two ICT values (2%) were < 0.30 indicating very poor reliability. In conclusion, in patients with Parkinson’s disease the intra-rater, inter-rater, and test-retest reliability of the individual components of the instrumented TUG (iTUG) was excellent to good for total duration and for turning durations, and good to low for the sub durations and for the kinematics of the SiSt and StSi. The results of this fully automated analysis of instrumented TUG movements demonstrate that several reliable TUG parameters can be identified that provide a basis for a more precise, quantitative use of the TUG test, in clinical practice.
