Examination of Biomechanical Characteristics of Linea Alba in Diastasis Recti Patients

Examination of Linea Alba Biomechanical and Viscoelastic Characteristics in Patients Diagnosed With Diastasis Recti Using Ultrasound

Diastasis recti is an increased distance between the rectus abdominis muscles at the midline caused by weakness in the anterior abdominal wall.

Study Overview

• Status: Not yet recruiting
• Conditions: Separated Recti Abdominis
• Intervention / Treatment: Device: Ultrasonography; Device: The MyotonPRO Device

Detailed Description

Most healthcare providers agree that in diastasis rectus abdominis there is a weakness, thinning, and widening of the linea alba and weakness of the associated abdominal musculature.

Ultrasonography is regarded as the most accurate method for measuring the IRD and its results are consistent with the data derived from palpation, calipers, and intraoperative measurements.

The MyotonPRO Device is used for the non-invasive measurement of Device is for the non-invasive measurement of biomechanical and viscoelastic properties of superficial soft biological tissues. Skeletal muscles or tendons can be measured at different regions, at full rest or in contraction.

This study aims to assess the biomechanical and viscoelastic properties of the Linea Alba in patients who are diagnosed with diastasis rectus abdominis by ultrasonography.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
20 Women in the Postpartum Diastasis Recti Group	Device: Ultrasonography; Ultrasound is an assessment device that uses high-energy sound waves to look at either superficial tissues like linea alba and/or organs inside the body. The sound waves make echoes that form pictures of the tissues and organs on a computer screen (sonogram).; Device: The MyotonPRO Device; The MyotonPro is a portable device for measuring biomechanical and viscoelastic properties in superficial soft tissues
20 Women in the Control Group (Postpartum Without Diastasis Recti)	Device: Ultrasonography; Ultrasound is an assessment device that uses high-energy sound waves to look at either superficial tissues like linea alba and/or organs inside the body. The sound waves make echoes that form pictures of the tissues and organs on a computer screen (sonogram).; Device: The MyotonPRO Device; The MyotonPro is a portable device for measuring biomechanical and viscoelastic properties in superficial soft tissues
