Triple Compression Stress Test Special Test
Orthopedic Physical Examination & Clinical Assessment Guide
What is it used for?
- Diagnosing Tarsal Tunnel Syndrome (Posterior Tibial Nerve entrapment).
- Considered more sensitive than Tinel's Sign for this condition.
How to Perform
- Position: Patient lies supine or sits with the leg relaxed.
- Action: The examiner places the ankle in full Plantar Flexion and Inversion (Supination).
- Compression: Simultaneously, the examiner applies constant digital pressure over the posterior tibial nerve (behind the medial malleolus). Maintain for 30 seconds.
Interpretation of Results
- Positive Test: Reproduction of numbness, tingling, or paresthesia in the foot or toes (plantar distribution).
Diagnostic Accuracy
- Sensitivity: 85-92%
- Specificity: 86-100% (Magee)
Clinical Context & Limitations
The Triple Compression Stress Test 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 Ankle & Foot region, combining the Triple Compression Stress Test with complementary examination tests significantly improves overall diagnostic confidence.
