How this service works
Graham 2006 CTS-6 from six caller-assigned booleans with published discrete weights (median-territory numbness 3.5, nocturnal numbness 4, thenar atrophy or weakness 5, Phalen 5, two-point discrimination loss 4.5, Tinel 4; max 26). Score >5 is associated with ≈25% probability of CTS; score >12 with ≈80%. magent does not examine the patient. Deterministic published arithmetic with citation; not a CTS diagnosis, not an EMG order, not a Boston questionnaire, and not a medical device.
Output
Returns the computed CTS-6 total score (maximum 26) derived from summing the weighted boolean inputs per Graham 2006 published weights. A score above 5 is associated with approximately 25% probability of CTS; a score above 12 with approximately 80% probability. The response does not constitute a diagnosis, EMG order, or medical device output.
Example use cases
Pre-referral CTS triage in primary care
“I've got a patient with nocturnal numbness, median territory numbness, and a positive Phalen test, but no Tinel sign, no thenar atrophy, and no two-point discrimination loss — can you run the CTS-6 score and tell me the associated CTS probability?”
Documenting clinical decision rationale
“For my chart note, calculate the CTS-6 score for a patient with all six findings positive: median numbness, nocturnal numbness, thenar atrophy, positive Phalen, positive Tinel, and two-point discrimination loss.”
Ruling out CTS in low-suspicion presentation
“My patient has a positive Tinel sign only — no other CTS features. What does the Graham 2006 CTS-6 score come out to, and what probability of CTS does that suggest?”

Endpoint
GEThttps://api.magentlab.com/api/calc/cts_6When to prefer
Use this endpoint when you need a deterministic, citation-backed arithmetic computation of the Graham 2006 CTS-6 score from caller-supplied physical exam booleans, and when you explicitly do not need EMG results, the Boston Carpal Tunnel Questionnaire, or any patient-interactive diagnostic device. Prefer this over generic medical knowledge retrieval when reproducibility and a published reference score are required.
Side effects
- Missing any of the six required boolean query parameters returns a validation error
- Non-boolean values for boolean parameters cause a parse or validation error
- Network or payment authorization failure returns an HTTP 402 or 5xx error
