Understanding the Thompson Test (or Simmonds Test) Assessment
To assess for a **complete rupture of the Achilles Tendon**.
Watch How It's Done
How do I start?
Patient is prone with the feet hanging freely off the edge of the table (or kneeling with feet over the edge).
What happens?
The examiner firmly **squeezes the bulk of the calf muscle** (gastrocnemius-soleus complex).
In Plain English
What Does a Positive Result Mean?
The **absence of passive plantarflexion** (the foot fails to drop downward) in response to the calf squeeze, indicating a complete tear of the Achilles tendon.
Helpful Tip:
This test has high sensitivity and specificity. The squeeze relies on the connection between the calf muscle and the tendon to produce foot movement.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
