The Beighton scale is a nine-point scoring system used to measure generalized joint hypermobility, which is the ability to move joints beyond the normal range of motion. It’s the standard clinical tool for screening and diagnosing hypermobility conditions, and it takes only a few minutes to perform. Originally developed as a quick way to screen large populations, it was later adopted for individual diagnosis and remains central to the criteria for hypermobility spectrum disorders and hypermobile Ehlers-Danlos syndrome.
How the Nine Points Are Scored
The Beighton scale tests five specific movements, four of which are checked on both sides of the body. Each positive result earns one point, for a maximum of nine.
- Pinky finger extension: Can you bend your little finger backward past 90 degrees? One point per hand (2 points possible).
- Thumb to forearm: Can you bend your thumb forward to touch your forearm? One point per hand (2 points possible).
- Elbow hyperextension: Do your elbows bend backward past straight by more than 10 degrees? One point per arm (2 points possible).
- Knee hyperextension: Do your knees bend backward past straight by more than 10 degrees? One point per leg (2 points possible).
- Forward bend: Can you place your palms flat on the floor with your knees fully straight? One point (1 point possible).
A clinician typically performs these checks in sequence, sometimes using a handheld device called a goniometer to measure the exact angle at the elbows and knees. The whole assessment usually takes under five minutes.
What Your Score Means
The most commonly used cutoff is a score of 4 or higher out of 9, which is considered a positive result for generalized joint hypermobility. But that single threshold doesn’t fit everyone equally well. A large cross-sectional study of an Australian population found that a cutoff of 4 was only appropriate for women aged 40 to 59 and men aged 8 to 39. Outside those groups, age- and sex-specific cutoffs produced more accurate results.
This matters because joint flexibility naturally decreases with age. A 60-year-old who scores 3 may have been significantly hypermobile earlier in life, while a young child who scores 4 might simply have the normal flexibility of childhood. The 2017 diagnostic criteria for hypermobile Ehlers-Danlos syndrome account for this by using different thresholds: a score of 5 or higher for adults over 50 and 6 or higher for children who haven’t finished puberty.
A positive Beighton score alone doesn’t equal a diagnosis. It identifies generalized joint hypermobility, which is common and often causes no problems at all. Clinicians use it as one piece of a larger assessment that considers symptoms like chronic pain, frequent joint dislocations, skin elasticity, and family history before diagnosing a condition like hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome.
Where the Scale Falls Short
The Beighton scale was designed in the 1970s as a quick epidemiological screening tool, not a comprehensive joint assessment. It checks only five joint areas (pinkies, thumbs, elbows, knees, and spine), which means it misses hypermobility in the shoulders, hips, ankles, and feet entirely. Someone with significant hypermobility in those joints but normal range in the areas the scale measures could score below the cutoff and be missed.
Researchers are actively working to address this gap. The Ehlers Danlos Society is currently evaluating four additional joint assessments covering shoulder flexion, forearm rotation, ankle flexibility, and big toe extension to improve recognition of hypermobility that the Beighton scale alone would miss. For now, experienced clinicians often supplement the Beighton score with broader physical examination when they suspect hypermobility despite a low score.
Another limitation is that the scale captures a snapshot in time. Joint range of motion can vary with temperature, time of day, hormonal changes, and how warmed up your muscles are. Previous injuries or surgeries can also reduce range of motion at specific joints, lowering the score even when underlying hypermobility is present.
How Reliable Is It?
Despite its simplicity, the Beighton scale produces consistent results. A systematic review published in the Orthopaedic Journal of Sports Medicine found that it shows substantial to excellent reliability both when the same clinician repeats the test and when different clinicians assess the same person. About 63% of reliability measurements across studies fell in the “substantial to almost perfect” range, and this held true regardless of the rater’s background or experience level.
That consistency is one reason the scale has remained the standard for decades. It’s quick, requires no special equipment, and produces results that different clinicians can reproduce. While it has real limitations in which joints it covers, what it does measure, it measures well.
Beyond the Score: What Comes Next
If you score at or above the threshold for your age group, the next step is evaluating whether your hypermobility is causing problems. Many hypermobile people are completely healthy. Dancers, gymnasts, and musicians often score high on the Beighton scale, and their flexibility is an asset rather than a medical concern.
Hypermobility becomes clinically relevant when it’s accompanied by symptoms: chronic joint or muscle pain, joints that sublux (partially dislocate) or fully dislocate, fatigue, slow wound healing, or unusually stretchy skin. A clinician will typically review your symptom history, examine additional joints beyond the five the Beighton scale covers, and may assess related systems like your skin and cardiovascular health. The Beighton score is the starting point of that process, not the finish line.
