This study will prospectively measure the effectiveness of a core strengthening program on reducing the inter-rectus distance (IRD) and abdominal wall muscle contraction in postpartum women with diastasis rectus abdominus (DRA). Additionally, this study will aim to investigate and clarify the association between IRD and low back pain.
DRA is a separation of the abdominal wall muscles that commonly occurs during pregnancy and is caused by the stretching of the linea alba to accommodate a growing fetus. Separation of core muscles is thought to be factor in postpartum low back pain, stress urinary incontinence, and core strength, as well as being cosmetically undesirable. This study will evaluate the effect of a core strengthening program on shortening the IRD and improving the connectivity and strength of abdominal wall muscles in postpartum women with a DRA. It will also investigate the relationship between IRD and low back pain.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Core Strengthening Exercise Intervention | Experimental | All subjects will participate in the study for a total of 24 consecutive weeks. During the first 12 weeks, subjects will participate in weekly online exercise classes for Core Muscle Strength training and will be asked to perform daily homework assignments. Following completion of the 12-week intervention, subjects will be asked to continue the exercises on their own. |
|
| Control+Core Strengthening Exercise | Active Comparator | All subjects will participate in the study for a total of 24 weeks. During the first 12 weeks, subjects will serve as the control group, and they will be advised to continue their baseline level of exercise and lifestyle. During the subsequent 12 weeks, subjects will participate in the exact same program as Group A performed during the first 12 weeks (Core Muscle Strength Training). |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Core Muscle Strength Training | Other | Targeted weekly workouts consisting of low-impact aerobic exercises and resistance exercises designed to address muscle imbalance common in women who exhibit DRA and to prompt automatic core engagement while performing compound, multi-joint movements. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in inter-recti distance (IRD) | Change in IRD will be measured using palpation and musculoskeletal ultrasound. | Up to 24 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Abdominal wall muscle function | Measured using musculoskeletal ultrasound at rest and during contraction (abdominal draw-in maneuver). | Up to 24 weeks |
| Low back pain | Measured using the Quebec Back Pain Disability Scale. Scores range from 0 to 100, with 100 representing higher disability. |
