Collagen: Your Body's Essential Scaffolding
Ever wondered why a paper cut heals differently than a deep muscle strain? The answer lies in collagen—your body's most abundant protein and the literal framework holding everything together.
Collagen acts like the steel reinforcement in concrete. Just as rebar gives concrete its tensile strength and prevents cracking, collagen provides the structural integrity for your skin, tendons, ligaments, blood vessels, and even your bones. It's not just present—it makes up roughly 30% of all protein in your body.
Here's what makes collagen remarkable: it's organized in triple-helix strands that create incredibly strong fibers. These fibers resist stretching and provide the 'bounce-back' quality in healthy tissues. When you bend your finger, stretch your skin, or absorb impact through your joints, you're relying on collagen's structural properties.
But when collagen production is disrupted—whether through genetics, nutrition deficiencies (like vitamin C), or aging—the effects ripple throughout your entire body. This explains why conditions like Ehlers-Danlos Syndrome don't just affect one area; they create widespread joint hypermobility, fragile skin, and vascular issues. The scaffolding itself is compromised.
Next time you notice your skin's elasticity or feel your joints' stability, you're experiencing collagen at work. Understanding this helps explain why injury recovery, aging changes, and even dietary choices matter for tissue health.
Example
A patient with collagen deficiency experiencing both joint hypermobility and easy bruising—seemingly unrelated symptoms connected by one underlying structural issue
Collagen is the glue that holds the body together.
What Hypermobility Actually Means
Ever noticed someone who can bend their thumb back to touch their forearm, or lock their knees backward? That's hypermobility—when joints move beyond the typical range most people have. It's often called being 'double-jointed,' though your joints aren't actually double—they just extend further than average.
Here's what's important to understand: hypermobility itself isn't a disease or disorder. It's simply a physical characteristic, like being tall or having flexible hamstrings. Research shows that 10-20% of the population has some degree of hypermobility, and many function perfectly well without ever experiencing problems.
The issue arises when your muscles can't adequately stabilize those extra-mobile joints. Think of it like this: if your joints are doors that swing wider than normal, you need stronger door stops (muscles) to control that movement. Without adequate muscular control, those joints can become unstable, leading to pain, fatigue, or injury.
Example: A gymnast with hypermobile shoulders might perform beautifully because they've built the strength to control that range. Meanwhile, someone with similar joint mobility but poor muscle control might experience shoulder pain with overhead activities.
Next time you notice unusual joint flexibility, ask yourself: 'Do I have the strength to control this range?' That's where the real work begins.
Example
A gymnast maintaining shoulder stability through strength training versus untrained hypermobile joints becoming painful
Flexibility without stability is just another word for instability.
Ehlers-Danlos Syndrome: Beyond Just Flexible Joints
Can you touch your thumb to your forearm? While impressive party tricks, some people's flexibility comes with a hidden cost—systemic health challenges that extend far beyond their joints.
Ehlers-Danlos Syndrome (EDS) is a genetic condition affecting how your body produces or processes collagen—the protein that acts like scaffolding throughout your entire body. Think of collagen as the structural glue holding tissues together. When it's faulty, the consequences ripple everywhere.
Unlike simple hypermobility, EDS is a syndrome—a collection of symptoms affecting multiple body systems. Yes, joints are hypermobile, but that's just the visible tip. People with EDS often experience skin that bruises easily and tears like tissue paper, wounds that heal poorly, chronic widespread pain, and digestive issues from a 'stretchy' gut. Some types affect the heart and blood vessels, while others impact neurological function.
From a movement perspective, this matters enormously. A patient with EDS doesn't just need joint stability exercises—they need careful consideration of tissue fragility, pain management strategies, and understanding that their fatigue isn't laziness; it's their body working overtime to compensate for faulty building materials.
Next time you assess someone with 'just' hypermobility, consider: Are there other signs suggesting something more systemic? Early recognition changes everything about how we approach their care.
Example
A patient presenting with shoulder instability, easy bruising, and chronic fatigue—recognizing the pattern leads to appropriate referral and management rather than just treating the joint
EDS isn't about being extra flexible—it's about having a body where the structural foundation itself is compromised.
The Hypermobility Spectrum: Where Do You Fall?
Can you touch your thumb to your forearm? While your friend with the same flexibility experiences chronic pain, you feel fine. What's the difference? Hypermobility exists on a spectrum—and where you fall determines everything about your care needs.
At one end sits asymptomatic hypermobility: you're naturally flexible, perhaps excelled at gymnastics or yoga, but experience no pain or complications. Your joints move beyond normal ranges, but your body handles it beautifully. No treatment needed—you've won the genetic lottery.
Move along the spectrum and you'll find Hypermobility Spectrum Disorder (HSD). Here, those flexible joints cause problems: recurrent sprains, chronic pain, joint instability. You don't meet the strict criteria for a genetic condition, but you're definitely not "just flexible." This is where targeted physiotherapy becomes crucial.
At the far end lies Ehlers-Danlos Syndrome (EDS)—a genetic condition where hypermobility comes with widespread systemic issues: skin fragility, digestive problems, cardiovascular complications. This requires specialized medical management beyond joint care alone.
Example: Two dancers with identical Beighton scores (a flexibility test). One performs pain-free for decades (asymptomatic). The other develops chronic ankle instability and needs structured strengthening programs (HSD).
From a movement perspective, your position on this spectrum isn't about how flexible you are—it's about how your body tolerates that flexibility. Understanding this guides whether you need monitoring, physiotherapy, or comprehensive medical care.
Example
Two individuals with 8/9 Beighton scores: one is an asymptomatic yoga instructor, the other requires ongoing physiotherapy for joint pain and instability
Flexibility without control is just instability waiting to happen.
Why Hypermobile Bodies Need Different Strategies
Ever been told to 'just stretch more' when you can already put your palms flat on the floor? For hypermobile bodies, this common advice can actually worsen pain and instability.
Hypermobility means your joints move beyond normal ranges—you have too much flexibility, not too little. The real challenge? Your nervous system struggles with proprioception (sensing where your joints are in space), and your tissues lack the stability to control that extra range safely.
Think of it like a door with loose hinges. Adding more range (stretching) makes the problem worse. What you need are stronger hinges (stability) and better awareness of when the door is open or closed (proprioception).
From a movement perspective, this means shifting focus to controlled strengthening and position awareness exercises. Your tissues are more vulnerable to injury, so gradual progression isn't just smart—it's essential for breaking the pain-injury cycle.
Next time someone suggests yoga or stretching, ask yourself: 'Do I need more range, or better control of the range I already have?'
Example
Instead of touching your toes with straight legs, practice controlling the movement down and back up with a slight knee bend
For hypermobile bodies, stability is the new flexibility.
Review Key Concepts
- What is collagen and why is it important?
Collagen is your body's most abundant protein (30% of total protein), providing structural integrity like steel reinforcement in concrete. It creates strong triple-helix fibers that give tissues their 'bounce-back' quality and resistance to stretching.
- What is hypermobility?
Hypermobility is when joints move beyond the typical range most people have—often called being 'double-jointed.' It's a physical characteristic affecting 10-20% of the population, not inherently a disease or disorder.
- Why do hypermobile joints struggle with stability?
Hypermobile bodies struggle with proprioception (sensing joint position in space), and tissues lack stability to control extra range safely. It's like a door with loose hinges—more range without control worsens instability.
- What is Ehlers-Danlos Syndrome (EDS)?
EDS is a genetic condition affecting how your body produces or processes collagen. It's a syndrome—a collection of symptoms affecting multiple body systems, including hypermobile joints, fragile skin, poor wound healing, and chronic widespread pain.
- What is the hypermobility spectrum?
Hypermobility exists on a spectrum from asymptomatic (flexible but no problems) to Hypermobility Spectrum Disorder (HSD) (pain and instability) to EDS (genetic condition with systemic effects). Where you fall determines your care needs.
- What is asymptomatic hypermobility?
Asymptomatic hypermobility means you're naturally flexible with joints moving beyond normal ranges, but you experience no pain or complications. Your body handles the extra mobility beautifully—no treatment needed.
- What is Hypermobility Spectrum Disorder (HSD)?
HSD occurs when flexible joints cause problems—recurrent sprains, chronic pain, joint instability—but you don't meet strict criteria for a genetic condition like EDS. Your hypermobility is symptomatic and requires management.
- Why is 'just stretch more' bad advice for hypermobility?
Hypermobile bodies have too much flexibility, not too little. Adding more range through stretching worsens instability. What's needed is stability (stronger support) and better proprioception (joint position awareness), not more flexibility.
- What is the stability-first approach for hypermobility?
From a movement perspective, hypermobile bodies need controlled strengthening and position awareness, not more stretching. Focus shifts to building stability through the available range and training the nervous system to sense joint position accurately.
- Why do different tissues heal at different rates?
Collagen organization determines healing speed. Skin has abundant blood supply and simple collagen structure (heals quickly). Tendons and ligaments have dense, organized collagen with poor blood flow (heal slowly). Understanding this guides realistic recovery expectations.
