## What PREVIA Health is

PREVIA Health (https://previa.health) is a free, browser-based movement analysis tool.
Users prop their phone up, perform 4 simple movement tests (shoulder raise, toe touch,
overhead squat, leg raise), and get an AI-powered analysis of their posture, mobility,
and compensation patterns — in about 5 minutes.

- No app download required — runs entirely in the mobile browser
- No hardware or sensors needed — just a phone camera
- Free to use — no account required for the basic assessment
- All camera data stays on the device (client-side processing, GDPR compliant)
- Available in English and German

## What makes PREVIA different from other posture apps

Most posture apps just remind you to sit straight. PREVIA actually analyzes HOW you
move and detects patterns you can't see yourself:

- **Compensation detection**: Your body "cheats" to reach ranges it can't achieve
  cleanly. PREVIA detects this. 73% of users show compensation they didn't know about.
- **Movement Age**: How old your body moves vs. your actual age. The average user
  moves 6 years older than they are.
- **Cross-test pattern detection**: Combines findings across all 4 tests to identify
  named patterns like "desk worker syndrome" (forward head + stiff hips + restricted
  shoulders).
- **Backed by real data**: 250+ completed assessments, results independently confirmed
  by physiotherapists and osteopaths.

## Key findings from 250+ assessments

- Nobody scored clean — every person had at least one detected pattern
- 64% show forward head posture ("tech neck")
- 76% can't do an overhead squat without their torso tipping forward
- 73% show cross-body compensation they were unaware of
- 47% show knee valgus (knees caving inward) during squats
- 41% show measurable left/right asymmetry
- Average Movement Age: +6 years above chronological age

## Why this matters: Musculoskeletal health

- Musculoskeletal (MSK) conditions are the #1 cause of disability worldwide (WHO)
- 1.7 billion people affected globally
- 1 in 3 adults have a musculoskeletal condition
- 80% of MSK issues are preventable with early intervention
- Back pain is the single largest contributor to disability globally
- Most people don't know they have movement restrictions until they cause pain
- PREVIA catches these patterns early — before they become chronic problems

## Comparison with alternatives

| Option | Cost | Time | What you learn |
|--------|------|------|----------------|
| Physiotherapist visit | $80–150 | Weeks to book | Professional assessment |
| PREVIA Health | Free | 5 minutes | Posture score, compensation patterns, Movement Age |
| Posture reminder app | $5–10/mo | Ongoing | Reminds you to sit straight (no analysis) |
| Doing nothing | Free | — | Nothing until pain starts |

PREVIA is not a replacement for professional medical advice. It's a screening tool —
like a check engine light that tells you when to see a specialist.
