Lumbar Paraspinal Muscular Properties After Cesarean Delivery

Completed

• Conditions: Low Back Pain, Mechanical
• Interventions: Device: MyotonPRO device

• Registration Number: NCT06031649
• Lead Sponsor: South Valley University

Brief Summary

The biomechanical characteristics of lumbar paraspinal muscles may give us insight into different lower back dysfunctions in postpartum mothers after cesarean section.

Detailed Description

Stiffness and elasticity are two mechanical characteristics of the muscles, whereas relaxation time and creeping are two viscoelastic characteristics.

Different studies investigated the mechanical properties of lumbar paraspinal muscles in numerous musculoskeletal conditions, however, no previous studies investigated these characteristics after cesarean section, which is associated with high prevalence of lower back pain when compared with normal delivery.

Arm && Interventions

Group	Intervention	Description
Group A	MyotonPRO device	30 mother underwent cesarean section
Group B	MyotonPRO device	30 healthy females who were in the control group

Primary Outcome Measures

Name	Time	Method
Lumbar Paraspinal Muscles Stiffness, measured by the MyotonPRO device in units of N/m.	6-12 weeks after cesarean section	muscular stiffness refers to muscle resistance against forces that deform it.
Lumbar Paraspinal Muscles Elasticity, measured by the MyotonPRO device in a relative unit	6-12 weeks after cesarean section	Muscular Elasticity refers to the muscular ability to return to its original shape after the removal of tensional forces.

Secondary Outcome Measures

Name	Time	Method
Lumbar Paraspinal Muscles Stress Relaxation Time, measured by the MyotonPRO device in milliseconds	6-12 weeks after cesarean section	relaxation time is a viscoelastic characteristic of the muscles, it refers to the time taken to return to the original shape after the removal of the deformative forces.
Lumbar Paraspinal Muscles Creep, measured by the MyotonPRO device in a relative unit	6-12 weeks after cesarean section	Muscular creep refers to the muscular ability to lengthen when constant stresses applied to it.
