Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intermittent trunk flexion
60-min intermittent trunk flexion protocol.
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in muscle stiffness
Time Frame: 90 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.
90 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in range of motion
Time Frame: 90 minutes
Trunk flexion range of motion will be evaluated using inertial measuring units during bending in standing position.
90 minutes
Change in length of the spine
Time Frame: 90 minutes
The length of spine will be measured on a custom-developed stadiometer, with the participants in a seated position.
90 minutes
Change in muscle activity
Time Frame: 90 minutes
Muscle activity will be measured using electromyography during standing.
90 minutes
