Summary

An experimental study, which will aim to compare changes of trunk mechanical properties and neuromuscular control following spinal flexion exposure in crane operators and control subjects.

Detailed description

Our experimental study will include 40 participants, more specifically 15 crane operators and 15 control subjects. All participants will complete a 60-min protocol of intermittent trunk flexion. Measurements of trunk mechanical properties and neuromuscular control will be performed prior to and following the 60-min protocol.

Conditions

• Occupational Exposure

Interventions

Type	Name	Description
OTHER	Repeated trunk flexion	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.
