Being Flexible Isn’t the Same as Being Stable: Understanding Joint Hypermobility and How Physical Therapy Can Help

If you’ve ever popped a shoulder out of place reaching into the back seat, felt your kneecap slide carrying laundry upstairs, rolled an ankle stepping off a curb you had already seen, or been the person who could bend a thumb to their forearm, you may be living with joint hypermobility.

Here is the number that reframes it: in a UK study of six thousand fourteen-year-olds, roughly 27.5% of girls and 10.6% of boys met the common screening threshold for generalized hypermobility.[1] Being bendy is ordinary. What is not ordinary is that extra range arriving with recurring partial dislocations, pain in several joints, and fatigue that does not match what you did. That combination is what joint hypermobility exercises are built to address.

The good news? Your only option is not to protect yourself and wait. The research here is young and imperfect, but the muscles around a loose joint can be trained to do work the connective tissue is not doing.

At Rooted Motion Physical Therapy, we believe understanding why a joint feels unreliable changes what you are willing to try.

What Is Joint Hypermobility?

Joint hypermobility means a joint moves beyond a typical range. It is a trait, not a diagnosis, and it becomes clinically meaningful when it travels with symptoms. A 2017 consensus framework introduced the term hypermobility spectrum disorder for symptomatic hypermobility that does not meet criteria for hypermobile Ehlers-Danlos syndrome.[2] The two are not ranked tiers of seriousness. A study of 97 adults found that after coordinated physical therapy more than half of both groups reported lasting improvement, with no difference between them.[3]

Common experiences include joints that partially slip out or fully dislocate with little force—often shoulders, kneecaps, fingers and ankles; pain in several joints rather than one; fatigue out of proportion to activity; and symptoms that flare after activity that felt fine at the time. Diagnosis requires a clinical evaluation.

Why Do Hypermobile Joints Hurt?

Every joint is held by two systems. The passive system—ligaments, capsule, connective tissue—restrains without you doing anything. The active system—muscles, and the nervous system timing them—restrains moment to moment. In hypermobility the passive system offers less, and the active system often has poorer information. Researchers comparing walking in adults with Ehlers-Danlos syndrome against healthy adults found delayed thigh-muscle activation and weaker hip and ankle muscles, while the joint angles were essentially the same.[4] The difference was the timing and the control.

Imagine a Storm Door Without Its Closer

Picture the storm door on a Virginia porch. A working door has a pneumatic closer along the top that lets it swing open, holds it partway, and eases it shut without slamming. Take the closer off and the door still opens—further than before, and more easily. Nothing is torn. But it slams in a gust and bangs the frame until the hinges complain. Nobody would fix that door by opening it wider.

The key idea: more range is not the goal—control through range is. The connective tissue is not going to become tighter, so the target is muscles and a nervous system that can steer the joint through the range you already have.

Is Stretching the Problem, or Is It How Far You Stretch?

“Every provider I’ve seen tells me I’m tight and hands me stretches. I do them, I feel amazing for ten minutes, and then everything hurts worse.” The explanation is more nuanced than “stretching is bad for hypermobile people.”

Start with what the evidence does not show. No good-quality trial has found that stretching worsens pain, partial dislocations or joint stability. The 2017 clinical framework notes that avoiding joint hyperextension may not be necessary, and that stretching can give up to around 24 hours of relief by easing muscle spasm.[5] Expert guidance includes gentle stretching alongside strengthening and balance work.[6]

The useful distinction is not stretching versus no stretching. It is what you are stretching for, and how far you go. Easing a muscle that is guarding—working overtime to supply restraint the ligaments are not—is reasonable. Chasing more range in a joint that already has plenty is where consensus places the risk of provoking a slip or a flare. Yoga sits in that tension: hypermobile bodies get rewarded for going deeper, at the end range where a joint is least protected.

One more point reverses an instinct many people develop after years of flares. What expert consensus does identify as clearly worsening instability is prolonged rest and inactivity, along with muscle relaxants—both reduce muscle tone and condition.[5] The joint you stop using does not become safer.

What Does the Research Actually Say?

We will be more candid than most articles here, because the honest version is more useful. The evidence base for exercise in joint hypermobility is thin, small and inconsistent. A 2021 systematic review screened 1,045 references and found six randomized trials, sample sizes of 20 to 57, with “huge heterogeneity” in the interventions. Its conclusion: physiotherapy benefits pain and position sense, but “robust randomized control studies are missing.”[7] Existing trials are mostly single-joint and short on follow-up.[6]

The largest trial is a shoulder study. One hundred adults with hypermobility spectrum disorder and shoulder symptoms were randomized to sixteen weeks of heavier, full-range strengthening or lighter, mid-range exercise. The heavier program improved more—but by less than the trial’s own threshold for a meaningful difference, reaching it only among those who completed the sessions. There were no serious adverse events, though the heavier group reported more temporary soreness.[8] At one year the advantage was no longer statistically significant.[9]

How Should You Actually Train?

Two reasonable bodies of evidence point in slightly different directions, and you deserve both. Published physical therapy guidance is the more conservative: trunk control first, then stability at the individual joints, and only then strengthening—load kept low, repetitions increased before resistance.[6] The best single trial points the other way, favouring more load sooner.[8] One sixteen-week single-joint study is a narrow base for overturning broad guidance, so in practice that usually means starting nearer the conservative end and progressing on how you respond.

• Closed-chain before open-chain. Hand or foot fixed—a wall push, a mini squat—before free-moving versions.[6]

• Reps before resistance. Add repetitions first and increase load later, progressing more slowly than a person without hypermobility would.[6]

• Expect months, not weeks. No validated dose exists, and several months are typically needed before pain meaningfully improves. Programs usually begin supervised and continue as a home routine.[6]

Is Some Discomfort During Exercise Okay?

Generally, yes. A common clinical guide is that discomfort at or below roughly 3 to 4 out of 10 during exercise is acceptable. The more important check is the 24-hour rule: symptoms should settle to your baseline within about a day. If they are still elevated, reduce the load rather than stop. A joint slipping out during an exercise is different from soreness—that means the position, load or range needs changing.

What About the Dizziness and the Fatigue?

If you have wondered whether lightheadedness on standing and joint pain are connected, that is a question the literature is actively working on. For people who have both, the guidance is more specific than it used to be: a 2021 review explicitly recommends semi-recumbent and horizontal exercise—swimming, recumbent cycling—because they reduce the strain of being upright, with upright work added over the following months and exercise modified to protect loose joints.[10] No trial has compared recumbent against upright starting positions head to head, so this is reasoning from mechanism rather than proof.

The Rooted Motion Difference

The changeable part of all this is the active system, and that is what physical therapy addresses. A coherent plan also replaces a scattered one—many people have collected a folder of unconnected advice from providers who each saw one joint. Care is one-on-one, unhurried, and built around your life rather than a clinic’s schedule. We serve Richmond, Midlothian and Henrico. Here is what you can expect:

• A thorough evaluation that looks at the whole system, not one joint in isolation.

• A plan built around what you actually need to do—your work, your kids, your hobbies.

• Honest conversation about what the evidence supports and where it remains uncertain.

• Training progressed gradually and adjusted to how you respond, not to a fixed timeline.

• Practical strategies for managing flares and spreading effort across a week.

• Convenient concierge mobile physical therapy delivered where you are.

Being seen at home means training your stairs, your kitchen counter and your kids’ car seats—where control actually gets tested.

Ready to Feel Steady in Your Own Body Again?

Whether it started with a shoulder that slips when you reach behind you, knees that ache after a walk along the Capital Trail, or a year of fatigue nobody has connected, you do not have to navigate this alone. Physical therapy will not change your connective tissue. What it can work toward is a body that responds more predictably and joints that feel governed rather than precarious.
