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

Lumbar Paraspinal Muscles Stiffness, measured by the MyotonPRO device in units of N/m.
muscular stiffness refers to muscle resistance against forces that deform it.
Time frame: 6-12 weeks after cesarean section
Lumbar Paraspinal Muscles Elasticity, measured by the MyotonPRO device in a relative unit
Muscular Elasticity refers to the muscular ability to return to its original shape after the removal of tensional forces.
Time frame: 6-12 weeks after cesarean section
Lumbar Paraspinal Muscles Stress Relaxation Time, measured by the MyotonPRO device in milliseconds
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.
Time frame: 6-12 weeks after cesarean section
Lumbar Paraspinal Muscles Creep, measured by the MyotonPRO device in a relative unit
Muscular creep refers to the muscular ability to lengthen when constant stresses applied to it.
Time frame: 6-12 weeks after cesarean section
