Seven assessments. One four-photo posture scan and six guided movements. Here is each one, what it looks at, and what Flexa takes from it.
Stand tall and relaxed while the app takes four photos: front, back, left side, right side.
Where your head, shoulders, ribcage, hips, knees and feet sit when you are not trying. Side by side, the four views show tilt, rotation and shift, left to right and front to back.
Joint positions and angles: your resting shape, and which way your frame is leaning and turning before any movement happens. It is the baseline every movement result is compared against.
Feet flat, arms forward, lower down as far as you comfortably can.
How deep you can go, how your ankles, knees and hips share the work, and whether your chest stays up or folds forward on the way down.
Whether you load front or back, and how evenly you load left and right, under your own body weight.
Step one foot directly in front of the other, as if on a line, and lower.
Balance on a narrow base, how far your hips open, and how much your knee drifts in or out as you lower, one side at a time.
The left-to-right difference. This is where a side that has been quietly doing more work usually shows up.
Lift one leg over an imaginary hurdle and set it down, keeping your torso quiet.
Whether your hips stay level while one leg does the work, and how much your upper body has to swing to get the leg across.
How well you hold a steady middle when only one leg is on the ground. This is the pattern behind most walking and stair complaints.
Keep your hips facing forward and turn your upper body to each side.
How far you turn each way, and whether your hips or feet cheat the turn.
Which direction your ribcage prefers. A turn that is easy one way and stiff the other is a strong pattern signal.
Reach overhead and lean back as far as feels comfortable.
Where the bend comes from, whether your upper back opens or your low back does all the work, and how far your arms get overhead.
How your ribcage and low back divide the job of extending. Uneven sharing here is one of the most common findings.
Feet together, knees soft, reach down toward your toes.
How your spine rounds along its length, how far your hips fold, and whether your weight travels forward or back over your feet.
Where movement is coming from and where it is missing. This is the clearest read on how the front and back of your body are sharing the load.
The Neural Code, a pattern-recognition engine created by neuroscientist Dr. Sheila Nirenberg (Cornell, MacArthur Fellow), licensed to Spiral Health for movement assessment, reads your six movement results and picks which of eight movement patterns best describes your body. Your daily program follows from that.
Flexa uses your camera two ways. The four posture photos become joint positions and angles, essentially geometry. The six guided movements are read by the Neural Code, which classifies how you move into one of eight movement patterns. Both feed the program Flexa builds for you. Full processing and retention details are in our privacy policy. Fully on-device processing, our "Privacy Airlock" architecture, is in active development and not shipping today.
You can repeat the seven assessments whenever you like, so progress is measured against your own baseline. Alongside them, Flexa asks the same questions clinical researchers ask.
Where a validated instrument exists for a region, we use it. Where one does not, we use our own ten-item function scales — hip, knee, ankle, lower extremity and upper back — scored the same way every time so your change over time is meaningful. We do not present those as validated instruments, because they are not: they are ours, and we say so.
Wellness marketing has an evidence problem: borrowed studies and blurred attribution. Here is exactly whose result is whose.
Flexa delivers an integrated postural and movement therapy method. The primary source is The SPINE CARE Randomized Clinical Trial: 2,971 people across 33 centers, whose individualized postural therapy arm delivered this method in person.
These results belong to the method and the clinicians who delivered it. The trial ran before the Flexa app existed. Flexa is how the method reaches your phone.

Where we reference digital musculoskeletal results from other programs, such as Hinge Health's reported 2.4× ROI or Sword Health's reported 3.2:1, those are their published figures about their own programs, cited for market context only. They are not claims about Flexa.
Sources: the respective companies' public disclosures.
Flexa's product-level outcome studies are under way. Until they publish, we do not claim product-level clinical results. What we can say today is that every member's progress is captured on validated instruments, so the evidence base is being built into the product.
Status: in progress. This page will be updated as results publish.
Flexa is a wellness product, not a medical device. It assesses how you move, builds a personalized movement program, and coaches you through it. It does not diagnose, treat, or cure any condition, and nothing on this page should be read as a claim that it does.
Take the seven assessments today. Take them again in a month.
