Reliability and Validity of Inline Dynamometry Study for Measuring Knee Extensor Torque

Anterior Cruciate Ligament Injuries Clinical Trial

Official title:
A Prospective Cross-sectional Study to Determine the Reliability and Validity of Inline 'Pull' Dynamometry for Measuring Peak Knee Extensor Torque in Patients Following Anterior Cruciate Ligament (ACL) Reconstruction: HRA & HCRW Approval Issued.

Clinical Trial Summary

This study will investigate the reliability and validity of an inline 'pull-type' dynamometer for measuring peak knee extensor torque. For the reliability study, healthy volunteers will be assessed by two assessors (inter-rater) at the index testing session, with testing repeated by one assessor one week later (test-retest). Validity will be investigated against isometric electromechanical dynamometry (gold standard) in patients following anterior cruciate ligament (ACL) reconstruction.

Clinical Trial Description

This is a prospective, cross sectional study using a within-participant, repeated measures design. The inter-rater and test-retest reliability of the KForce Link (pull-type dynamometer) will be determine using 50 healthy subjects. The validity of the KForce Link will be determined using 52 post-operative ACL reconstruction patients against the gold standard of isometric electromechanical dynamometry (Cybex). All testing will be performed isometrically with the knee positioned at 60 degrees knee flexion. Assessors and participants will be blinded to the scores until testing is complete. ;
