Not Applicable
Completed
Conditions
Occupational Exposure
Registration Number
NCT05511896
Lead Sponsor
University of Primorska
Brief Summary

An interventional study on the effects of repeated trunk flexion exposure on trunk neuromuscular properties.

Detailed Description

An interventional study will include 16 healthy young adults. All participants will complete a 60-min protocol of intermittent trunk flexion. Measurements of trunk neuromuscular properties will be performed prior to and following the 60-min protocol.

Primary Outcome Measures
NameTimeMethod
Change in muscle stiffness90 minutes

Muscle stiffness will be measured in prone lying using ultrasound-based shear wave elastography. Erector spinae and multifidus muscle stiffness will be expressed as the shear modulus value in kilopasquals.

Secondary Outcome Measures
NameTimeMethod
Change in length of the spine90 minutes

The length of spine will be measured on a custom-developed stadiometer, with the participants in a seated position.

Change in muscle activity90 minutes

Muscle activity will be measured using electromyography during standing.

Change in range of motion90 minutes

Trunk flexion range of motion will be evaluated using inertial measuring units during bending in standing position.
