Wrist & Hand
Nerve Compression
Evidence: suggestive
Tinel's Sign (Wrist) Special Test
Orthopedic Physical Examination & Clinical Assessment Guide
What is it used for?
- Diagnosing Carpal Tunnel Syndrome (Median Nerve).
How to Perform
- Action: Examiner lightly taps (percusses) over the median nerve at the carpal tunnel (wrist crease).
Interpretation of Results
- Positive Test: Tingling or "electric shock" sensation in the thumb, index, and middle fingers.
- Why: An irritated nerve is hypersensitive to mechanical percussion.
Diagnostic Accuracy
- Sensitivity: 70%
- Specificity: 90%
Clinical Context & Limitations
The Tinel's Sign (Wrist) should be considered as one component of a comprehensive musculoskeletal assessment. No single special test has perfect diagnostic accuracy; thus, clinical decision-making should integrate test results with patient-reported symptoms, mechanism of injury, functional impairment, and relevant imaging.
Clinicians should be aware of potential false-positive results in patients with pain sensitisation, muscle guarding, or poor relaxation. For the Wrist & Hand region, combining the Tinel's Sign (Wrist) with complementary examination tests significantly improves overall diagnostic confidence.
