Brief Summary

Cesarean delivery (CD) may trigger an increase in low back pain (LBP) intensity and induce core muscle weakness. This study will assess the correlation between low back pain intensity and core muscle strength of transverse abdominis and Lumbar multifidus among women who underwent CD and compare it with those who experienced vaginal delivery.

Detailed Description

Cesarean delivery (CD) is one of the most common surgical procedures in obstetrics, and it is also one of the oldest medical procedures. The rise in the rate of cesarean sections is one of the most striking hallmarks of modern obstetrics.

In Egypt, the prevalence of CD has increased dramatically over the last decade, with the most recent Egypt Demographic and Health Survey (EDHS) reporting a rate of 52 percent, implying that cesarean sections may be overused or utilized for improper reasons.

The two deep local core muscles are the transversus abdominis and the lumbar multifidus muscles. The definition of Core muscle strength is the active ability of these muscles to not only produce but also, maintain stresses to provide stability for the spine through management of the intra-abdominal pressure.

LBP prevalence in mothers undergoing cesarean delivery was higher compared to its counterpart in mothers undergoing vaginal delivery. The related mechanisms for LBP during the postpartum period following cesarean or vaginal deliveries may be overweight and obesity, postural adaptations, and stressful positions that mothers assume during either delivery or lactation.

Primary Outcome Measures
NameTimeMethod
The intensity of LBPAssessment will be done 6-12 weeks after Cesarean OR Vaginal deliveries

The intensity of low back pain is a standardized method to quantify the severity of low back pain

The maximal voluntary isometric contraction of the transversus abdominis muscleAssessment will be done 6-12 weeks after Cesarean or Vaginal Deliveries

The maximum voluntary isometric contraction (MVIC) is an objective standardized method with high reliability used to evaluate and quantify muscle strength

The maximal voluntary isometric contraction of the lumbar multifidus muscleAssessment will be done 6-12 weeks after Cesarean or Vaginal Deliveries

The maximum voluntary isometric contraction (MVIC) is an objective standardized method with high reliability used to evaluate and quantify muscle strength

The correlation coefficient between low back pain intensity and core muscle strengthAssessment will be done 6-12 weeks after Cesarean or Vaginal Deliveries

The correlation coefficient between two variables of outcome is a valid statistical method to the association between them
