Reliability and Validity of the Evaluation of Hip Abductors Strength (RAVEHABDS)

• Conditions: Healthy People
• Interventions: Other: Maximal voluntary isometric strengthening

• Registration Number: NCT05140577
• Lead Sponsor: HES-SO Valais-Wallis

Brief Summary

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.

Detailed Description

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).
