Brief Summary

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

Conditions

Occupational Exposure

Keywords

bending, load, stiffness, elastography, deformation

Outcome Measures

Primary Outcomes (1)

• Change in muscle stiffness

  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.

  90 minutes

Secondary Outcomes (3)

• Change in range of motion

  90 minutes

• Change in length of the spine

  90 minutes

• Change in muscle activity

  90 minutes

Study Arms (1)

Intermittent trunk flexion

EXPERIMENTAL

60-min intermittent trunk flexion protocol.

Other: Repeated trunk flexion

Interventions

Repeated trunk flexion OTHER

A 60-min intermittent trunk flexion protocol. Participants will sit on a standard height sit, with their knees bent at approximately 90° with their hands crossed on their chest. They will perform 40 sets of 60 s of maintaining a flexed position, interspersed with 30 s of rest. Participants will achieve the flexed position by tilting the pelvis posteriorly and leaning forward. During rest, participants will sit up straight without leaning on the support.
