About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Women who experienced cesarean section at least for one time
  • Women Who are free of specific lower back disorders
  • Women who are below 34 years old and above 20 years old

Exclusion criteria

  • Women who experienced normal vaginal birth
  • Women who complain of a specific lower back disorder

  • Women who have a body mass index above 30 Kg/m2

Treatment and study plan

MyotonPRO device

Device

It is a valid and reliable device for measuring the muscular mechanical properties

Other names: Myotonometry

Primary outcomes

  1. Lumbar Paraspinal Muscles Stiffness, measured by the MyotonPRO device in units of N/m.

    Time frame: 6-12 weeks after cesarean section

    muscular stiffness refers to muscle resistance against forces that deform it.

  2. Lumbar Paraspinal Muscles Elasticity, measured by the MyotonPRO device in a relative unit

    Time frame: 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 outcomes

  1. Lumbar Paraspinal Muscles Stress Relaxation Time, measured by the MyotonPRO device in milliseconds

    Time frame: 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.

  2. Lumbar Paraspinal Muscles Creep, measured by the MyotonPRO device in a relative unit

    Time frame: 6-12 weeks after cesarean section

    Muscular creep refers to the muscular ability to lengthen when constant stresses applied to it.
