Samenvatting

BackgroundA 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.

MethodsTwenty-nine participants with SIVD performed the Minimum Sit-to-Stand Height test (MSST), the Leg Extension test (LE) and the 30seconds Chair-Stand test (30sCS), once per week for 5weeks. 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.

ResultsA sufficient feasibility and learning period of the tests was shown. The methods had sufficient test-retest reliability and moderate-to-sufficient correlations.

ConclusionThe MSST, the LE, and the 30sCS are feasible tests for measuring muscle strength in persons with SIVD, having sufficient test re-test reliability.
