The quickest way to tell if you’re hypermobile is to check whether your joints bend noticeably further than most people’s. A standardized test called the Beighton score lets you assess this at home in about two minutes, using nine specific movements across your fingers, thumbs, elbows, knees, and spine. A score of 5 or higher out of 9 generally indicates hypermobility in adults, though the threshold shifts with age and sex. But the Beighton score only captures part of the picture. Hypermobility also shows up in your skin, your balance, your injury history, and patterns you may have never connected.
The Beighton Score: A Simple Self-Test
The Beighton score is a nine-point scale used by clinicians worldwide. You earn one point for each of these movements you can do:
- Pinky fingers: Bend each pinky finger backward past 90 degrees (one point per hand).
- Thumbs: Bend each thumb back far enough to touch your forearm (one point per hand).
- Elbows: Straighten each elbow past a neutral, straight position so it curves backward (one point per elbow).
- Knees: Straighten each knee past neutral so the leg bows backward when standing (one point per knee).
- Forward bend: Bend forward and place both palms flat on the floor without bending your knees (one point).
That gives you a maximum of nine points. The threshold for hypermobility depends on your age and sex, because joint flexibility naturally decreases over time. For women aged 8 to 39, a score of 5 or higher is considered hypermobile. For men in the same age range, it’s 4 or higher. After 40, the cutoffs drop: women need a score of 4 between ages 40 and 59, and just 3 between 60 and 69. Men over 40 may qualify with a score of only 2. Children before puberty are naturally more flexible, so a score of 6 or higher is the typical threshold.
You can do this test at home to get a rough sense of where you fall. But keep in mind that the Beighton score only tests five joint sites. It’s possible to have significant hypermobility in your shoulders, hips, ankles, or jaw that the test completely misses.
Signs You Might Notice in Daily Life
Many hypermobile people don’t realize their joints move beyond the normal range because it’s all they’ve ever known. Instead, the clues show up as patterns: you sprain your ankles more easily than your friends, your shoulder “pops out” during ordinary movements, or your knees lock backward when you stand. Frequent joint and ligament injuries, including partial dislocations (subluxations) and sprains, are one of the most common indicators.
Clumsiness and poor balance are also linked to hypermobility. Loose ligaments alter the way sensors inside your joints detect position and movement, a sense called proprioception. Research comparing hypermobile and non-hypermobile individuals found that those with higher Beighton scores had significantly worse accuracy when asked to position their elbows and knees at specific angles without looking. In practical terms, this means you might misjudge where your limbs are in space, bump into door frames, or feel unsteady on uneven ground.
Other everyday patterns worth noting: you may have always been the “flexible one” in gym class, you might sit in a W-position naturally, or you could find that your joints ache after standing or walking for periods that don’t bother other people. Chronic pain, especially in the knees, hips, or back, is common even when imaging shows nothing structurally wrong.
Skin and Body Clues Beyond the Joints
Hypermobility is a connective tissue trait, and connective tissue isn’t just in your joints. It’s in your skin, your gums, your blood vessels, and your organs. So the signs often extend well beyond flexibility.
One of the more reliable checks is skin stretchiness. To test this, gently pull the skin on the inside of your non-dominant forearm (the hairless side, near the wrist) until you feel resistance. If the skin stretches more than 1.5 centimeters, that’s considered hyperextensible. Avoid testing on the backs of your hands or over your knuckles, where skin is naturally looser. Skin that’s unusually soft or velvety to the touch, even without moisturizer, is another marker.
A few other physical features are associated with more generalized connective tissue involvement:
- Piezogenic papules: Small, skin-colored bumps that appear on the sides of your heels when you stand and disappear when you sit. These are tiny herniations of fat through the connective tissue of the heel. They need to be present on both feet to count as a clinical sign.
- Dental crowding and a high, narrow palate: If you needed orthodontic work as a teenager and also have a notably arched or narrow roof of your mouth, those two features together point toward connective tissue differences.
- Easy bruising: Bruises that appear with minimal impact, or that you can’t explain.
- Stretch marks: Especially if they appeared without significant weight changes.
Hypermobility, HSD, and hEDS: What the Labels Mean
Joint hypermobility itself is extremely common and often causes no problems at all. It only becomes a clinical concern when it’s paired with symptoms like pain, instability, or recurrent injuries. The terminology can be confusing, so here’s how it breaks down.
Generalized joint hypermobility (GJH) simply means your joints move beyond the typical range. It’s a physical trait, not a diagnosis. If that flexibility causes musculoskeletal symptoms but you don’t meet the full criteria for a specific connective tissue disorder, the diagnosis is hypermobility spectrum disorder (HSD). HSD is a real, recognized condition, not a lesser version of something else.
Hypermobile Ehlers-Danlos syndrome (hEDS) is the most restrictive diagnosis. It requires generalized hypermobility plus a combination of systemic signs (skin involvement, dental crowding, hernias, organ prolapse, or a tall and slender body type), along with a family history or musculoskeletal complications, and the exclusion of other connective tissue conditions. The diagnostic criteria were tightened significantly in 2017, which means some people who would have previously qualified for a hypermobility-type EDS diagnosis now fall under HSD instead. Both conditions are diagnosed purely through clinical evaluation. There’s no blood test or genetic marker for either one.
Conditions That Often Travel With Hypermobility
If you’re hypermobile and also deal with dizziness when standing, a racing heart, unexplained flushing, or gut problems, you’re not imagining a connection. Hypermobility frequently overlaps with autonomic nervous system dysfunction, particularly a condition called postural orthostatic tachycardia syndrome (POTS), where your heart rate spikes abnormally when you go from sitting to standing. Hypermobile EDS is the most common disorder associated with POTS, and one study found that 18% of people with POTS met the criteria for EDS. The likely mechanism is that lax blood vessels allow blood to pool in the legs, forcing the heart to compensate.
Mast cell activation issues also appear more often in this population. In a survey of over 4,800 people diagnosed with POTS, 25% also had EDS and 9% had been diagnosed with a mast cell activation syndrome, which can cause flushing, hives, gastrointestinal distress, and allergic-type reactions. The three conditions (hypermobility, POTS, and mast cell problems) overlap often enough that clinicians familiar with hypermobility will typically screen for all three.
Getting a Formal Assessment
Self-screening with the Beighton score and checking for skin and body signs can give you a strong sense of whether hypermobility is part of your picture. But a formal diagnosis, especially if you’re dealing with pain, instability, or related symptoms, requires a clinical evaluation. Rheumatologists are the most common specialists for this, though medical geneticists handle cases where a specific connective tissue syndrome needs to be confirmed or ruled out. Physical therapists with experience in hypermobility can also be valuable, both for identifying the pattern and for building a management plan focused on joint stability and strength training.
When you go in for evaluation, expect a hands-on joint exam, questions about your injury history, and an assessment of your skin. Bringing a written list of your symptoms, including things like fatigue, dizziness, digestive issues, and how long you’ve dealt with them, can help the conversation move faster. Many hypermobile people spend years seeing specialists for individual symptoms before someone connects the dots, so arriving with the full picture already laid out works in your favor.
