✋ CTS-6 (Carpal Tunnel Syndrome Diagnostic Score)
UseWhen to use: clinic diagnosis of CTS when EDX is deferred or adjunctive.
StrataHigher scores support clinical CTS; integrate differential (radiculopathy, polyneuropathy).
LimitsWhen not to use: acute trauma / infection hand pathways. · Pitfall: non-median numbness scoring. · Not a sole surgery booking.

When to use
When to use: clinic diagnosis of CTS when EDX is deferred or adjunctive.
How it works
Sum of six weighted history/exam items (max 26); >5 ≈25%, >12 ≈80% cues.
Key points
- Max 26.
- >12 high-probability cue.
- Next: night splint / EDX selective.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Numbness mainly in median territory (3.5) | No |
|---|---|
| Nocturnal numbness (4) | No |
| Thenar atrophy or weakness (5) | No |
| Positive Phalen test (5) | No |
| Loss of 2-point discrimination ≤5 mm (4.5) | No |
| Positive Tinel sign (4) | No |
→CTS-60.0/26
- Cue：≤5 — lower probability cue
| Numbness mainly in median territory (3.5) | Yes (+3.5) |
|---|---|
| Nocturnal numbness (4) | Yes (+4) |
| Thenar atrophy or weakness (5) | Yes (+5) |
| Positive Phalen test (5) | Yes (+5) |
| Loss of 2-point discrimination ≤5 mm (4.5) | Yes (+4.5) |
| Positive Tinel sign (4) | Yes (+4) |
→CTS-626.0/26
- Cue：>12 — ~80% probability cue for CTS in derivation teaching

FAQ
Frequently asked questions
- Does CTS-6 (Carpal Tunnel Syndrome Diagnostic Score) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is CTS-6 (Carpal Tunnel Syndrome Diagnostic Score) calculated in practice? Can you show a worked example?
- Inputs: Numbness mainly in median territory (3.5) No, Nocturnal numbness (4) No, Thenar atrophy or weakness (5) No, Positive Phalen test (5) No, Loss of 2-point discrimination ≤5 mm (4.5) No, Positive Tinel sign (4) No → Result: CTS-6 0.0 /26（Cue: ≤5 — lower probability cue） Inputs: Numbness mainly in median territory (3.5) Yes (+3.5), Nocturnal numbness (4) Yes (+4), Thenar atrophy or weakness (5) Yes (+5), Positive Phalen test (5) Yes (+5), Loss of 2-point discrimination ≤5 mm (4.5) Yes (+4.5), Positive Tinel sign (4) Yes (+4) → Result: CTS-6 26.0 /26（Cue: >12 — ~80% probability cue for CTS in derivation teaching）
