Can You Have hEDS or HSD With a Borderline Beighton Score?

Yes, you can still be diagnosed with hypermobile Ehlers-Danlos syndrome (hEDS) or Hypermobility Spectrum Disorder (HSD) even if your Beighton score is slightly below the age-specific cutoff. A borderline score does not invalidate your symptoms, nor does it rule out clinically important joint instability. The diagnostic criteria are designed to account for the fact that joint flexibility changes over time and can be affected by injuries, natural aging, or disease ^[1][2].

The Beighton Score Thresholds
The Beighton score measures your current range of motion across nine specific points on your body. Under the 2017 international criteria, the threshold for generalized joint hypermobility depends on your age and pubertal status ^[3][4]:

• Pre-pubertal children and adolescents: Score of 6 or higher (Note: an official hEDS diagnosis is typically reserved for those who have reached biological maturity ^[5][3]).
• Pubertal men and women up to age 50: Score of 5 or higher.
• Adults over age 50: Score of 4 or higher.

The “One Point Below” Rule and the 5-Part Questionnaire
If your current Beighton score is exactly one point below your age-specific threshold, the 2017 criteria state that your doctor should assess your historical hypermobility ^[6].

They do this using the Five-Part Questionnaire (5PQ), which asks you to recall your past flexibility (for example, whether you could touch your hands flat on the floor as a child, or if your kneecap or shoulder has ever dislocated). If your Beighton score is exactly one point below the threshold AND you answer “yes” to at least two of these five questions, your history supports the requirement for generalized joint hypermobility ^[7].

Important note: This specific pathway only applies if you are exactly one point below the cutoff. It is not a universal rule to convert any low score into a passing score, and it does not by itself diagnose hEDS.

Why a Beighton Score Might Underestimate Your Hypermobility
It is common for people with a convincing history of hypermobility to fall short on the Beighton score during an exam. A low score accurately measures your current mobility in those specific joints, but it may underestimate your overall or historical instability for several reasons:

• It only tests a few joints: The Beighton score relies heavily on the upper body. It does not measure the stability of the shoulders, hips, ankles, or feet ^[8][9]. You could have severe, localized instability in your shoulders or hips and still score a zero on the Beighton test ^[10].
• Stiffness and pain: Chronic pain, muscle spasms, and tight hamstrings can restrict your movement on the day of the exam. Pain during movement can prevent you from extending a joint to its full capacity, and you should never force a painful stretch just to achieve a point ^[11][12].
• Injuries and surgeries: Past traumas, recurrent dislocations, or joint surgeries often lead to scar tissue and stiffness, actively reducing your mobility over time ^[6].
• Age: Joints naturally stiffen as we get older, which is why historical hypermobility must be considered ^[1][2].

What the Score Can and Cannot Tell You
The Beighton score is a screening tool for selected range of motion, not a comprehensive test of joint instability or a severity score. A restricted score should prompt a discussion of your history and untested joints, not an immediate dismissal of your symptoms.

What This Means for hEDS vs. HSD
Meeting the generalized joint hypermobility requirement is only the first step in diagnosing hEDS ^[13]. To be officially diagnosed, you must also meet Criterion 2 (which requires at least two of three feature groups: systemic manifestations, musculoskeletal complications, or an affected first-degree relative) and Criterion 3 (the strict exclusion of other connective tissue disorders) ^[14][15]. Note that a family history is not mandatory to be diagnosed with hEDS, as long as you have enough systemic and musculoskeletal features.

If you have symptomatic hypermobility (such as joint instability, chronic pain, or recurrent dislocations) but you do not meet the full criteria for hEDS, your condition may be classified as Hypermobility Spectrum Disorder (HSD) ^[16][17]. HSD is not simply a “failed” hEDS diagnosis; it is a clinical classification for symptomatic hypermobility that can be generalized, peripheral, localized, or historical ^[18].

It is crucial to understand that HSD is not a “lesser” or “milder” diagnosis. Research shows that people with HSD often experience symptoms that substantially overlap with hEDS, including joint pain, frequent subluxations (partial dislocations), fatigue, and other multisystem complaints ^[19][20]. The medical management, pain relief, and physical therapy strategies for HSD are highly individualized but share the same foundational principles as hEDS care ^[21][22]. Receiving either label should support your access to symptom-focused care.
