Fit & Use

The best splint is the one that covers
your core well, supports the abdominals,
and is comfortable enough that you will
wear it consistently.

Find the right splint for you.

I loved that I could wear my splint under my work shirt and no one could even tell. That splint reminded me all day of how to stand and sit and work without collapsing. - Jeff

How to Choose Your Splint

When it comes to choosing a splint, here’s how to get it right:

  1. Get a tape measure or a piece of string that you can later measure against a ruler. When you measure, do
    not suck in and do not push out; measure the tummy you “live in.”
  2. In inches, measure from the top of your hipbone (right above the spot you feel when you bend your hip) to the bottom of your *rib cage. This number will be used to choose the height of your splint (6″, 9″, or 12″).
    • *Women: stop about an inch under your bra; Men: include your lower 2–3 ribs.
    • *If you are pregnant, measure over the front of your belly to determine your size. 
    • To determine your postpartum size, subtract 2-4 inches. 
  3. Next, in inches, measure around your tummy at the widest area (this is usually the navel). Record this number. It will be used to choose the width of your splint (XS, S, M, L, or XL).

Now that you have your recorded measurements, you can use the numbers to find the right size below.

Important Sizing Considerations:

– If you measure between heights, choose the splint that is shorter.
– Unless your belly measurement is within 1 inch of the smaller size, do not consider the smaller size.
If you are pregnant, decide whether you’re purchasing a splint for prenatal or postpartum use; rarely will the same splint work for both.If you are measuring for use while pregnant, measure the height over the front of your belly (include the belly bump) to determine if you need a 3 or 4 panel splint.
– If your belly measurement is close to the bigger size and you still have several weeks left in your pregnancy, purchase the larger size.
– To determine your postpartum size, subtract 2-4 inches.

How to Put On Your Splint

  1. Place the splint between your ribs and pelvis. (Overlap onto the ribs or pelvis is okay; just make sure the splint covers the main part of your abdomen).
  2. Stand with your feet hips’-width apart.
  3. Untuck your pelvis and keep your ribs aligned over the pelvis.
  4. Exhale and draw your navel to your spine.
  5. Pull the two sides of the splint across your middle and fasten the closure. It should be snug like a hug, but NOT tight like a tourniquet.  Supportive not restrictive.

Correct Use of Your Splint

  • Wear the splint all day (and, in some cases, all night) during the initial weeks of core rehab training or the first several weeks of postpartum training.
  • Wear the splint over a camisole, undershirt, or bellyband to limit skin irritation and decrease laundering, which comprises the Velcro®.
  • Splinting is only a portion of core rehabilitation. How you wear your splint and hold yourself while splinting is key to extending the life of your splint, and, ultimately, your recovery.
  • Focus consistently on slightly drawing your navel in away from the splint, NOT on resting into the splint.
  • Remember that the splint is meant to be temporary and helps place the muscles in proper alignment for rehabilitation. The transverse work your perform through exercise, posture and alignment, and functional activities is truly how the muscles heal and rebuild.

Other Information

  • Our splints should last about 12-16 weeks and are not intended for long-term use.
  • Keep laundering to a minimum by wearing the splint over a camisole, undershirt, or bellyband.
  • To launder, connect the splint by its Velcro® closure, hand wash, and then machine dry on low.
