FITsplint & Research

FITsplint support belt 

Why do we call it the FITsplint? The patented FITsplint* allows for a custom fit to you (dual straps that either overlap or lay flat, is fully adjustable, flexible and made of breathable material) 

A splint is a type of support that helps pull muscles or joints close together. The FITsplint helps support the stretched out abdominal muscles and tissue during pregnancy and postpartum. While keeping the core and pelvic floor strong with exercise is the most important step …a support belt is often helpful when dealing with excess pain, pressure, or large diastasis. The FITsplint can provide support to the back, belly, help reduce bladder pressure and if worn lower, provide compression to the pelvis for those dealing with pelvic girdle pain.

What does the research say about the FITsplint?

Maternity FITsplint - Wear as needed. For pregnant women who may need additional support for their back, bladder, belly, pelvic girdle pain (worn lower) can benefit from the FITsplint. Women who have a large diastasis during pregnancy may find relief from the FITsplint as well. The Maternity FITsplint can be worn postpartum..the straps will just wrap more around the back. 

Maternity FITsplint Reseach  - recent independent research by Utah Valley University 2025- evaluated the biomechanical effects of the FITsplint maternity support with pregnant runners. ​ This was a small but impactful study. The study measured pelvic and hip kinematics and ground reaction forces (GRF) using motion capture and an instrumented treadmill. ​

• Key Findings:
• Pelvic Tilt: The FITsplint significantly reduced anterior pelvic tilt (right: -64.15%, left: -57.94%)  suggesting improved pelvic alignment and reduced stress on the back. ​
• Pelvic Rotation: Left-to-right pelvic rotation decreased significantly (-27.56%), indicating enhanced pelvic stability. ​
• Pelvic Shifts and Ground Reaction Forces: No significant changes were observed in pelvic shifts or GRF, suggesting the FITsplint primarily affects alignment rather than force distribution. ​

The FITsplint shows promise as a non-invasive intervention to provide support, reduce excess pelvic tilt and reduce strain during physical activity in pregnant women. 

Post-Natal FITsplint - Recommended to wear postpartum for about 4-6 weeks while reconditioning the core and pelvic floor, especially if dealing with a separation 2 or more finger widths. 

• Research has shown that combined use of the FITsplint along with core reconditioning exercises improved trunk flexion strength faster than the exercise only group or those with no intervention. Exercise and the use of a binder may help promote collagen formation at the linea alba -Keshwani 2019

FITsplint BENEFITS

• Protects from further stress or strain
• Provides gentle compression, helps transfer load
• Provides proprioceptive feedback
• Supports the abdominal muscles, hips, back and pelvis
• Use both straps to gently lift belly to help reduce bladder pressure during pregnancy
• Supports weakened abdominal wall and tissue during healing process postpartum
• Wear lower around the hips to help reduce pelvic girdle pain

FITsplint FEATURES

• Elastic binder
• Allows full range of motion
• Does not restrict breathing patterns
• Easy to support weakened abdominal muscles without increasing *pelvic floor pressure
• Non-slip technology
• Straps can splint without overlapping or bunching

*Pelvic floor pressure

Abdominal binders used in study [FITsplints] were unlikely to evoke or exacerbate urogynecological symptoms through causing Intra abdominal pressure. -Keshwani, Mathur, McLean 2019

While rigid binders can cause intra-abdominal pressure, elastic binders do not. -Zhang et al. 2016 

Doming, coning or bulging occurs due to a weakened anterior wall either by diastasis recti (lengthening of the linea alba), lengthening of the abdominal muscles due to pregnancy or lack of ability to sustain muscle stiffness (being able to resist internal force). Training to increase core stiffness (resist force) as well as core strength (produce force) will improve the ability to create and handle higher Intra abdominal pressure which is critical to being able to produce more force.

FITsplint Research Summary

• The Maternity FITsplint shows promise as a non-invasive intervention to provide support, reduce excess pelvic tilt and reduce strain during physical activity in pregnant women.  - Astle, 2025
• Wearing the FITsplint while reconditioning the core and pelvic floor provides the most optimal environment for postpartum recovery than exercise alone.
• Physiotherapy interventions such as abdominal binding [such as the FITsplint] with exercise therapy can positively impact body image and trunk flexion strength. While a clinical trial investigating these interventions is feasible, further preliminary investigation is recommended. -Keshwani, Mathur, McLean 2019
• Wearing the binder immediately after the vaginal delivery provides greater stability to the woman’s body as it provides support to the stretched ligaments and muscles, as well as supports the spine and improves posture. Subsequently, reducing strain on lower back and pelvic ligaments and joints help in alleviating back and pelvic pain through taking the pressure off these regions. Reducing stress in these areas enhances the body’s ability to return to its pre-pregnancy alignment and shape and helps the woman to return to her normal activities and wardrobe sooner. - Pela, Spoora 2008
• Postpartum body garments provide support to abdominal wall, assist in abdominal muscles retraction, improve posture, stabilize loosened ligaments and provide support to the torso while vital organs returned to their pre-pregnancy position. So, many women reported returning to their pre-pregnancy sizes faster while using it. - Mokhtar 2010
