A feasible and reliable instrument to measure strength in persons with severe intellectual and visual disabilities (SIVD) is lacking. The aim of our study was to determine feasibility, learning period and reliability of three strength tests.
Twenty-nine participants with SIVD performed the Minimum Sit-to-Stand Height test (MSST), the Leg Extension test (LE) and the 30 seconds Chair-Stand test (30sCS), once per week for 5 weeks. Feasibility was determined by the percentage of successful measurements; learning effect by using paired t test between two consecutive measurements; test-retest reliability by intraclass correlation coefficient and Limits of Agreement and, correlations by Pearson correlations.
A sufficient feasibility and learning period of the tests was shown. The methods had sufficient test-retest reliability and moderate-to-sufficient correlations.
The MSST, the LE, and the 30sCS are feasible tests for measuring muscle strength in persons with SIVD, having sufficient test re-test reliability.
目前缺乏一种可行且可靠的工具来测量重度智力和视力残疾（SIVD）患者的力量。我们研究的目的是确定三种力量测试的可行性、学习周期和可靠性。
29名SIVD患者每周进行一次最低坐立高度测试（MSST）、腿部伸展测试（LE）和30秒坐立测试（30sCS），共进行5周。通过成功测量的百分比来确定可行性；通过连续两次测量之间的配对t检验来确定学习效果；通过组内相关系数和一致性界限来确定重测可靠性，并通过Pearson相关性来确定相关性。
测试显示出足够的可行性和学习周期。这些方法具有足够的重测可靠性和中度至足够的相关性。
MSST、LE和30sCS是测量SIVD患者肌肉力量的可行测试，具有足够的重测可靠性。
