1 in 20: The Hypermobile Pregnant Client You Weren't Trained to See

hEDS and HSD may affect 1 in 20 births. How to screen, adapt your manual therapy, and refer safely.

Roughly one in twenty births may involve hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobility spectrum disorder (HSD) — yet these conditions are widely under-diagnosed, and most birth professionals were never taught to screen for them.
The frustrating part? These clients are already in your chair, presenting with chronic pelvic pain, recurrent pelvic girdle pain, and a "stretchy" recovery that never quite consolidates. I see these people every day in the clinic and I am also one of them.

It's a collagen story. In EDS and HSD, collagen is structurally different — more elastic, less resilient — so the tissue supporting the pelvic organs is compromised from the outset. Then pregnancy adds relaxin on top. Baseline laxity plus hormonal softening compounds into instability that arrives earlier, runs greater, and lasts longer. This is exactly the tissue your fascial work targets, which is why your lens matters here and why it's important to understand the differences in hEDS and HSD.

Pelvic girdle pain is the loudest signal. Pelvic pain and instability run about four times more prevalent than in non-EDS pregnancies, and up to 88% of hEDS clients report PGP during pregnancy in case series — with earlier onset and longer postpartum persistence. Screen generalized joint hypermobility with the Beighton score (a 5 or more out of 9 is positive in most adults), remembering that a score is a flag, not a diagnosis, and that pregnancy itself increases laxity.

Read differently, dose differently. When baseline tissue is lax, palpation carries more diagnostic weight — prioritize asymmetry and glide quality over raw range. Expect a softer, later barrier. Expect more sensitivity, but also use less pressure than you think you are already using. Recalibrate your techniques: gentler amplitude on already-elastic round and broad ligaments; mobilize the SI joint for symmetry, then immediately pair with stabilizing input. The governing principle is mobilize judiciously, then load for stability — and expect a longer recovery arc. Less is more in this population.

Know your lane. Your hands-on work belongs with hEDS and HSD. Vascular EDS is a different risk category entirely — COL3A1 variants carry real risk of arterial and tissue rupture. If you see easy arterial bruising, translucent skin, a personal or family history of spontaneous rupture, or progressive cardiac signs, pause and refer to genetics, MFM, or cardiology before hands-on soft-tissue work.

Anchor your practice in the 2024 international childbearing guidelines (Pezaro et al., PLOS ONE), which include a dedicated physical-therapy supplement and frame individualized care as non-negotiable. Recognize the tissue, read it through your fascial lens, adapt your dose, and know when to hand off — that's care most of this population has never received.
