Validity and Reliability of Trunk Strength Device

NCT06330129 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

Summary

The study aims to evaluate the accuracy and consistency of assessing trunk muscle strength using an isometric device (Pegasus, Leipzig, Germany). Thirty healthy volunteers will undergo maximal isometric strength testing with the device, repeated one week later to assess repeatability. Surface electrodes will measure muscle activation, while MRI scans will assess structural condition.

Conditions

  • Trunk Muscle Strength

Interventions

DEVICE

CTT Pegasus

The intervention aims to assess the construct validity of trunk flexor, extensor, and rotator muscle strength using the CTT PEGASUS isometric dynamometer (Leipzig, Germany). This involves correlating muscle strength measured isometrically with its physiological determinants: MRI-based anatomical cross-sectional area (CSA) in the lumbar region and muscle activation measured via surface electromyography (EMG) of spine and trunk muscles. Additionally, the intervention will assess the test-retest reliability of isometric strength of trunk flexors, extensors, and rotators.
