What New Research on Fascia Means for People with Hypermobile Ehlers-Danlos Syndrome (hEDS)

If you have hypermobile Ehlers-Danlos syndrome (hEDS), you've probably experienced a frustrating contradiction: everyone tells you that you're "too flexible," yet your body feels incredibly tight.

Your neck feels stiff. Your shoulders ache. Your ribs feel restricted. Your hips feel locked up. You may even feel like your entire body is bracing against itself.

For years, healthcare providers struggled to explain why people with hEDS often experience significant stiffness and pain despite having excessive joint mobility. Emerging research into the fascial system is beginning to provide answers—and it may change how we think about treatment.

What Is Fascia?

Fascia is a continuous web of connective tissue that surrounds and connects every muscle, bone, nerve, blood vessel, and organ in the body. Rather than individual muscles working independently, fascia helps create a body-wide network that distributes force, provides support, and contributes to movement, stability, and body awareness. Healthy fascia is adaptable, elastic, and able to glide smoothly between layers of tissue. When fascia becomes restricted or dysfunctional, it can contribute to pain, stiffness, fatigue, and movement limitations.

New Research Suggests Fascia Plays a Major Role in hEDS

Historically, hypermobile EDS was viewed primarily as a disorder of loose ligaments and unstable joints. While joint hypermobility remains a hallmark feature, researchers are increasingly recognizing that fascial changes may play a significant role in many of the symptoms experienced by people with hEDS.

Studies have found alterations in the connective tissue matrix that may affect how forces are transmitted throughout the body. Researchers have also observed that people with hEDS frequently develop areas of fascial densification and increased tissue tension despite generalized laxity.

In other words, while some tissues are excessively mobile, others may become overly protective and restricted.

This may help explain why many people with hEDS experience:

• Chronic muscle tightness

• Neck and shoulder pain

• Rib and chest wall restrictions

• Headaches and migraines

• Jaw pain and TMJ dysfunction

• Pelvic pain

• Breathing difficulties

• Persistent fatigue

• A feeling that the body is constantly "holding tension"

  
  

Fibroblasts and Myofibroblasts: Why the Body Can Feel Stuck

One of the most fascinating developments in fascial research involves specialized connective tissue cells called fibroblasts.

Fibroblasts are responsible for producing and maintaining connective tissue. They continuously respond to mechanical forces, helping tissues adapt to stress and movement.

When tissues experience chronic stress, inflammation, injury, or prolonged tension, fibroblasts can transform into cells called myofibroblasts.

Unlike regular fibroblasts, myofibroblasts have the ability to actively contract.

Think of them as tiny tension-producing cells within the fascial system.

While this process is important for wound healing, excessive myofibroblast activity may contribute to chronic fascial tension and stiffness. Researchers believe these cells can create a self-sustaining cycle of tension within connective tissues.

For individuals with hEDS, ongoing joint instability may lead the nervous system to recruit additional muscular and fascial tension in an attempt to create stability. Over time, this may contribute to widespread pain, stiffness, and fatigue.

This helps explain why many people with hEDS describe feeling both "too loose" and "too tight" at the same time.

How Myofascial Therapy May Help

Myofascial therapy is a gentle manual therapy technique that focuses on improving the mobility and function of the fascial system.

Rather than forcing tissues to stretch, myofascial therapy uses sustained pressure and gentle tissue loading to encourage fascial glide, hydration, and relaxation.

Research suggests that manual therapy may influence connective tissue through a process called mechanotransduction.

Mechanotransduction refers to the way cells respond to physical forces. Gentle, sustained pressure appears to create biochemical signals within tissues that may help reduce excessive tension, improve tissue organization, and calm protective responses.

For patients with hEDS, this can be particularly important because aggressive stretching or forceful treatment often increases symptoms rather than relieving them.

Many patients report improvements in:

• Pain levels

• Muscle tension

• Headaches

• Breathing comfort

• Body awareness

• Sleep quality

• Overall relaxation

  
  

Beyond Myofascial Release: Other Manual Therapy Techniques That Can Help

At Intrinsic Physical Therapy & Wellness, we recognize that hEDS affects much more than joints alone. Treatment is most effective when it addresses the connective tissue system, nervous system, and movement system together.

Gentle Joint Mobilization

Although people with hEDS are hypermobile, some joints become functionally restricted due to muscle guarding and protective tension.

Carefully selected low-grade joint mobilizations can help reduce pain, improve movement quality, and decrease muscular compensation without increasing instability.

Craniosacral Therapy

Many people with hEDS also experience nervous system dysregulation, headaches, dizziness, sleep disturbances, and sensory sensitivity.

Craniosacral therapy uses a very gentle touch to support relaxation and parasympathetic nervous system activity. Patients often report feeling calmer, less overwhelmed, and more regulated following treatment.

Rib Cage, Diaphragm, and Pelvic Floor Mobilization

Breathing dysfunction is common in hEDS. Restrictions in the rib cage, diaphragm, and pelvic floor can contribute to neck tension, pelvic pain, fatigue, feelings of breathlessness, and poor core stability.

Because these structures work together as part of the body's pressure management system, manual therapy directed toward the rib cage, diaphragm, and pelvic floor may help improve breathing mechanics, reduce muscle guarding, and support more efficient movement and stability throughout the body.

Nervous System-Focused Treatment

Perhaps most importantly, manual therapy can help reduce the body's constant state of protective bracing.

When the nervous system begins to feel safer, muscles often stop working quite so hard to create stability. This can reduce pain, improve movement, and create a better foundation for strengthening exercises.

Manual Therapy Is Only One Piece of the Puzzle

While manual therapy can provide meaningful symptom relief, it is not a standalone treatment for hEDS.

Long-term success requires a comprehensive approach that includes:

• Progressive strength training

• Proprioceptive training

• Joint stabilization exercises

• Breathwork

• Nervous system regulation strategies

• Pacing and energy management

• Education and self-management

Manual therapy often helps create the conditions necessary for these interventions to be more successful.

The Bottom Line

New research is helping us understand that hypermobile EDS is not simply a condition of "loose joints." The fascial system, nervous system, and connective tissue cells themselves appear to play important roles in pain, stiffness, fatigue, and movement dysfunction.

For many individuals with hEDS, gentle myofascial therapy, joint mobilization, craniosacral therapy, and other hands-on treatments can help calm an overprotective system, reduce tension, and improve overall function.

At Intrinsic Physical Therapy & Wellness, we use evidence-informed manual therapy techniques alongside individualized strengthening and nervous system rehabilitation to help patients move with greater confidence, comfort, and resilience.
