Hypermobility vs flexibility
These are different things. Hypermobility describes joints that move beyond the typical range because of ligament laxity; flexibility describes how far muscles lengthen. A high Beighton score and feeling stiff in some stretches can happen together, because muscles often tighten to stabilize lax joints.
The Beighton score, a 9-point screen
The Ehlers-Danlos Society describes the 9-point Beighton system and its positive thresholds: 5 or more in adults, 4 or more over age 50, and 6 or more in children.
The five maneuvers
- Little-finger bends back beyond 90 degrees (1 point each hand).
- Thumb touches the forearm (1 point each thumb).
- Elbow hyperextends beyond 10 degrees (1 point each).
- Knee hyperextends beyond 10 degrees (1 point each).
- Palms flat on the floor with straight knees (1 point).
Age-adjusted positive thresholds
Because laxity decreases with age, the cutoff is lower for older adults and higher for children.
Hypermobility vs HSD vs hEDS
Most hypermobility is harmless. Missouri Medicine notes about 10 to 30 percent of people have some joint hypermobility, but only about 1 in 500 meet criteria for hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome. Per GeneReviews, hEDS requires generalized joint hypermobility plus systemic, family, and musculoskeletal criteria and exclusion of other conditions.
Why a high score does not always mean flexible
Muscles often tense around lax joints, so a high score can come with a smaller stretch range. This is why chasing more passive flexibility can backfire, and why strength and control usually matter more.
Training considerations
If your Beighton score reads high, strength and control through range are a common focus rather than pushing into ever-greater passive range. Ask a clinician about your result. Building stability around the joints tends to reduce the achy, unstable feeling.
Build stability around your range with ROMRx
ROMRx Base focuses on usable, controlled range, so your plan builds stability rather than chasing more laxity.
Frequently asked questions
What is a positive Beighton score?
5 or more out of 9 in adults, 4 or more over age 50, and 6 or more in children. It is a screening threshold for generalized joint hypermobility, not a diagnosis on its own.
Is hypermobility the same as being flexible?
No. Hypermobility is joint laxity; flexibility is muscle length. A high Beighton score and feeling stiff in some stretches can happen together, because muscles often tighten to stabilize lax joints.
Does hypermobility mean I have EDS?
Usually not. Some joint hypermobility is common, but only a small fraction of people meet criteria for hypermobility spectrum disorder or hEDS, which requires clinician assessment.
Can you score high on the Beighton screen and still feel stiff?
Yes. Muscles often tense to protect lax joints, so a high Beighton score can come with feeling tight in everyday stretching.
If my Beighton score is high, do I stretch or strengthen?
Strength and control through range are usually the priority over pushing into more passive range. Building stability around the joints tends to help more than aggressive stretching.
