THOMPSON
TEST
• Test positioning
The client lies prone on a table with the heels placed over the edge of the table.
• Action
With the gastrocnemius soleus complex relaxed, the therapist squeezes the belly of these muscles.
• Positive finding
When squeezing the calf muscles, a normal response would be to have the foot plantar flex.
Therefore, an absence of plantar flexion upon squeezing would be a positive test, indicating a possible rupture of the Achilles tendon.
The Thompson Test, credited to Dr. Simmonds Thompson, is used for diagnosing Achilles tendon ruptures by observing plantarflexion upon squeezing the calf muscle.
