• 1 other identifier: dynam-neurotyp-child
• Study Type: observational
• Target: 30
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Lower Limb; Assessment Tool; Force Measurement; Children

Keywords

dynamometry; lower limb; assessment; child

Outcome Measures

Primary Outcomes (1)

• Average Peak Torque

  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

Study Arms (1)

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

Interventions

Traction Dynamometry DEVICE

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.

Neuro-typical Children

Eligibility Criteria

• Age: 5 Years - 16 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

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.

You may qualify if:

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

You may not qualify if:

• 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.
