Commonly asked questions

The Thompson Test is less effective for diagnosing partial Achilles tendor tear. In cases where a partial tear is suspected, further imaging, such as an MRI or ultrasound, is recommended for a definitive diagnosis.

Yes, the Thompson Test is highly reliable for diagnosing a complete Achilles tendon tear. When the Achilles tendon is completely ruptured, squeezing the calf muscle will not produce any movement of the foot, indicating a positive result for this test. Nevertheless, it is essential to seek immediate medical attention for an acute Achilles tendon rupture to confirm the diagnosis and determine the appropriate course of treatment.

If the patient is accessible, the Thompson Test can be performed immediately after the injury. Early testing helps in quick diagnosis and timely intervention, crucial for optimal recovery outcomes.
