The aim is to evaluate the intra- and inter-tester reliability, construct validity and feasibility of a new functional measurement procedure in a closed chain position on one leg. For this purpose, we will test the maximal voluntary isometric force, as well as the muscular contraction speed of the hip abductor muscles.
Within this Master thesis project, we will investigate intra- and inter-tester reliability, as well as construct validity of a measurement procedure to assess hip abductor strength in a closed-chain position. Additionally, we aim to investigate some aspects of feasibility using a questionnaire about the measurement procedure and by evaluating if the test can be completing in a suitable timeframe for practical use. To investigate intra- and inter-tester reliability, as well as construct validity, we will analyze and compare the maximal voluntary isometric strength (MVIS) and the rate of force generated (RFG) of the three groups of healthy participant (group 1: 18-30 years old; group 2: 31-65 years old; group 3: 65+ years old).

Time frame: 1 March, 2022
Inter-tester correlation
Strength of correlation the measured values
Time frame: 1 March, 2022
Construct validity
Difference between groups by comparing values

Feasibility of the measurement procedure
Through the administration of a feasibility questionnaire we investigate the time to perform the test, the understanding of the instructions, the fatigue, the possible pain, or the fear of falling during the test
