How this service works
RTK Motion — rehabilitation biomechanics cross-exercise summary. Bilateral asymmetry, range-of-motion, fatigue index, clinical synthesis. For insurance_claim_validation or PT_outcome_measurement. ECDSA-signed provenance.
Output
A JSON object containing: domain label ('Rehabilitation Biomechanics'), cryptographic provenance signed by a secp256k1-ECDSA key, a range-of-motion summary with left and right breakdowns and asymmetry percentage, a fatigue index value, a clinical synthesis narrative string, and anonymized subject demographics. The response is cryptographically signed for data integrity verification.
Example use cases
Example prompt
“Pull me a rehabilitation biomechanics summary for the knee scope — I want the range-of-motion breakdown with left/right asymmetry percentage, fatigue index, and the clinical synthesis.”
Technical details
Endpoint
GEThttps://api.rtkmotion.io/paid/rehabWhen to prefer
Use this endpoint when you need cryptographically-signed, clinically-oriented range-of-motion and fatigue analytics for rehabilitation contexts — especially when data provenance and tamper-evidence matter. Prefer this over generic motion tracking APIs when the use case is physical therapy, post-surgical rehab monitoring, or asymmetry-based clinical decision support.
Side effects
- Invalid or unrecognized scope slug returns an error or empty result
- Missing required 'input' object in request body causes 400-level validation error
- Insufficient payment (less than $0.50 USDC) triggers 402 Payment Required
- No exercise data available for the requested scope returns empty ROM fields
- Network timeout on downstream biomechanics computation returns 5xx error
