Clinical trial NCT06031649: Lumbar Paraspinal Muscular Properties After Cesarean Delivery
Official title: Lumbar Paraspinal Muscular Properties After Cesarean Delivery
Study type: OBSERVATIONAL
Overall status: COMPLETED
Conditions: Low Back Pain, Mechanical
Lead sponsor: South Valley University
Sponsor class: OTHER
First posted: 2023-09-11
Enrollment: 60
Sex: FEMALE
Minimum age (years): 20
Maximum age (years): 34
Standard ages: ADULT
Accepts healthy volunteers: no
Observational model: CASE_CONTROL
Time perspective: RETROSPECTIVE
Sampling method: PROBABILITY_SAMPLE
Study population: 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

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.

Eligibility criteria: 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

Primary outcomes:
measure: Lumbar Paraspinal Muscles Stiffness, measured by the MyotonPRO device in units of N/m.
timeFrame: 6-12 weeks after cesarean section
measure: Lumbar Paraspinal Muscles Elasticity, measured by the MyotonPRO device in a relative unit
timeFrame: 6-12 weeks after cesarean section
Secondary outcomes:
measure: Lumbar Paraspinal Muscles Stress Relaxation Time, measured by the MyotonPRO device in milliseconds
timeFrame: 6-12 weeks after cesarean section
measure: Lumbar Paraspinal Muscles Creep, measured by the MyotonPRO device in a relative unit
timeFrame: 6-12 weeks after cesarean section
