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.

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 are above 34 years old or below 20 years old
• Women who have a body mass index above 30 Kg/m2

A study in the scope of physiotherapy for women's health

60 females participated in this research, aged between 20 and 34 years old. They were free of specific lower back disorders. They were recruited from the outpatient clinics of South Valley Hospitals
