Introduction: To determine the value of shear wave elastography (SWE) in assessing abdominal wall muscles, includ- ing rectus abdominis (RA), external oblique muscle (EO), internal oblique muscle, and transversus abdominis (TrA) in patients with diastasis recti abdominis (DRA) and healthy controls. Methods: From October 2018 to December 2019, 36 postpartum DRA patients and 24 nulliparous healthy women were identifed. Inter-rectus distance (IRD) measurements were taken by B-mode ultrasound. Shear wave speed (SWS) values were acquired by one operator at ten specifc locations. Clinical and ultrasound variables, including demographics, IRD, muscle thickness, and mus- cle SWS, were compared between the two groups using Student’s t test or Fisher’s exact test. Pearson correlation analyses were conducted for the variables of IRD, muscle thickness, and SWS in the 36 DRA patients. Results: The maximum diameter of recti abdominus separation was located at the umbilicus in DRA patients (4.59±1.14 cm). The SWS value was signifcantly lower in the RA (p=0.003) and higher in the TrA muscle (p < 0,001) in DRA patients compared with the age-matched controls. However, SWS in both muscles (RA and TrA) showed a statistically posi- tive correlation with IRD (p<0,05) In addition, the SWS value in EO statistically decreased in DRA patients compared with the healthy controls (1.65±0.15 vs. 1.79±0.14, p=0.001). Conclusion: The application of SWE to abdominal wall muscles in DRA patients is feasible. The correlation between SWS value and IRD in RA should be interpreted with caution.
