• Conditions: Sacroiliac Joint Dysfunction

• Registration Number: NCT06820827
• Lead Sponsor: Cairo University

Brief Summary

This study will be conducted to investigate the effect of high-power pain threshold ultrasound on postnatal sacroiliac joint pain.

Detailed Description

Sacroiliac joint pain (SIJ) in the pregnant and postpartum females is susceptible to dysfunction due to multiple biomechanical changes that happen over the course of gestation. This includes an increased angle of lordosis, weight gain, and structural trauma due to the physiologic process of childbirth, biomechanical changes, along with hormonal fluctuations through each trimester, particularly with increased levels of estrogen and relaxin, have been found to decrease the stability of the joint leading to sustained postpartum back pain that may necessitate surgical intervention if conservative treatment fails.

PGP can result in significant physical disability and has important psychosocial implications, including extended leave from work during pregnancy and postnatal, poorer quality of life (as a result of being unable to carry out normal roles, affecting their ability to care for their children and the new baby) and predisposition to chronic pain.

There are side effects to using medical treatment for PGP, such as bruising, bleeding, stomach upset (including bleeding in the stomach), peptic (stomach) ulcers, blurred vision, constipation, dry mouth, fatigue, headaches, insomnia, mood changes, nausea, urination problems, and weight gain. So, using other treatment methods, such as ultrasound therapy to treat PGP is beneficial.

Ultrasound therapy is a non-invasive treatment in which sound waves penetrate soft tissues, increasing blood flow; this can help relieve pain, improve circulation, and promote tissue healing. As such, ultrasound therapy is often used to treat injuries, muscle spasms, and chronic issues like neck or back pain.

No previous study has investigated the effect of high-power pain ultrasound on sacroiliac pain in postpartum women. So, this study aims to investigate the effect of high-power ultrasound on postnatal sacroiliac joint pain.

Primary Outcome Measures

Name	Time	Method
Pain intensity	8 weeks	A numerical rating scale will be used to evaluate pain intensity for all participants before and after the end of the treatment program. It will be given to each participant to rate her intensity of pain. 0 indicates no Pain, 1-3 indicates mild pain (nagging, annoying, interfering little with activity of daily living (ADLs), 4-6 indicates moderate pain (interferes significantly with ADLs), and 7-10 indicates severe pain (disabling; unable to perform ADLs).
Pressure pain threshold (PPT)	8 weeks	A pressure algometry (Force Dial model FDK 20 Push Pull Force Gage, Wagner Instruments, Greenwich CT, USA) will be used to assess pain sensitivity by measuring pressure pain thresholds (PPT) at five selected points in the sacroiliac joint region of the affected side. The first examined point will be 1 cm medial and inferior to the posterior superior iliac spine, while the other four examined points will be 2 cm lateral, medial, superior, and inferior to the first point. Each point was measured three times with a ten-second interval between them; the mean of them will be then calculated for each point to be utilized for statistical analysis.

Secondary Outcome Measures

Name	Time	Method
Function disability	8 weeks	Pelvic Pain Impact Questionnaire (PPIQ) will be used to assess function disability. It consists of 8 questions that get scored 0-4, for a total of 32. 0 indicates no at all and 4 indicates great deal.
