About this trial

An experimental study, which will aim to investigate the acute effects of unloading maneuvers during an intermittent spinal flexion protocol on changes in trunk mechanical and neuromuscular properties.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Occupational workers with a predominantly non static job (e.g. combination of sitting and standing)

Disqualifiers

History of chronic low back pain

Episode of acute low back pain

Hip injury in the past six months

Previous spine, pelvis or hip surgery

Trial design

Design model

Parallel

Treatments tested in this trial

  • Unloading maneuvers

    Other intervention

    Participants will perform unloading maneuvers four times with 15 min of spinal flexion protocol in between. The intervention will include self traction on a box (5 s) and sustained standing trunk extension (8 s). Both maneuvers will be repeated twice at each timepoint.

Treatment groups

30 Participants
are divided into 2 treatment groups
Group A: Control groupNo intervention 0 interventions
Group B: Intervention groupExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Change in muscle stiffness

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

Time frame
90 minutes

Secondary outcomes

1

Change in range of motion

Trunk flexion range of motion will be evaluated using Spinal Mouse in maximal trunk flexion while standing.

Time frame
90 minutes
2

Change in seated spinal height

Seated spinal height will be measured on a custom-developed stadiometer, with the participants in a seated position.

Time frame
90 minutes
3

Change in lumbar lordosis angle

The lumbar lordosis angle will be evaluated using Spinal Mouse during upright standing.

Time frame
90 minutes
4

Change in trunk extension maximal strength

Isometric trunk extension peak torque will be assessed on a trunk dynamometer.

Time frame
90 minutes
