Effort measurement for IME and workers comp

Effort scoring that shows its work.

Flexion is a prototype effort score for workers compensation, disability, and IME work. No number goes in a report until it holds up against 3D motion capture.

What Flexion does

Three problems in effort measurement that every examiner, claims adjuster, and defense counsel faces. Flexion is built to address them honestly.

Rule-in, not rule-out

A positive effort flag is worth real weight. A negative one clears nobody. Flexion reports both halves of the diagnostic, not just the one that fits the narrative.

Ground truth first

The standard is simple: no movement number goes in a report unless it survives a check against 3D motion-capture ground truth.

Capture gates, not guesses

A single phone camera invents scatter the body never produced. So Flexion's approach is a second camera, a depth signal, or a capture gate that rejects bad angles before scoring.

The research behind it

Grip strength coefficient of variation is the most common effort test in IME work. But most reports cite the wrong specificity number, and most video effort tools skip the ground-truth check entirely. We pulled the primary data and tested it.

Pilot offer: $100 per assessment

Flexion is a prototype. The validation study has not run yet. The pilot is set up so you carry none of that risk.

What you get

An effort consistency report on each of your next 20 FCEs, built from video of the exam you already run. It reports movement consistency only. It never labels anyone a malingerer.

What it costs

$100 per assessment for those 20. Nothing is billed until the validation study clears its preregistered bar.

If the study misses

The pilot is free, and I send you what the data showed. You lose nothing but the time to reply.

One question: would you put 20 exams through at $100 once the study clears? A yes or a no both help.
