Lower Extremity Dynamometry Assessment in Neurotypical Children

December 19, 2025 updated by: George Paras, University of Thessaly

Reliability and Validity of Lower Extremity Dynamometry Assessment in Neurotypical Children

The purpose of this study is to assess the reliability (intra-rater and inter-rater) and criterion validity (using a Cybex isokinetic dynamometer as the reference) of the K-Pull (traction) dynamometer for evaluating lower limb function in children with neurotypical development.

Study Population

The study population consists of typically developing children aged 5 to 16 years, selected based on specific inclusion and exclusion criteria to ensure the reliability and validity of traction dynamometry.

Description

Inclusion Criteria:

  • typically developing children,
  • between the ages of 5 and 16 years,
  • have the capacity for voluntary motor control

Exclusion Criteria :

  • undergone any treatment or intervention that could impact neuromuscular performance, such as surgery or medication use,
  • experienced a recent injury
  • demonstrating low levels of compliance during assessments are not included in the study.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Neuro-typical Children
Typically developing children aged 5 to 16 years with the ability of voluntary motor control are in included in the study.
Device: Traction Dynamometry
K-Pull dynamometer (Model MP.09.02.FN, Kinvent, Montpellier, France) is an assessment tool used to quantify muscle strength. It uses traction through a non-elastic strap to facilitate isometric contractions. This instrument will be used to evaluate isometric activity (maximum and average torque values) of the hip and knee flexors and extensors at specific joint angles.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average Peak Torque
Time Frame: Through study completion, an average of 5 months
Average Peak Torque refers to the average highest force output recorded during isometric contractions and represents the maximal strength generated by the muscle group being assessed (e.g., hip or knee flexors and extensors). Unit of Measure: Newton-metre (Nm)
Through study completion, an average of 5 months
