What does a positive Thompson test indicate?
A positive test has been reported to indicate a complete rupture of the tendon,4 and the cited mechanical reason for the positive test (complete rupture) is the loss of integrity of the soleal part of the tendon.
How do you do a calf squeeze test?
This test may be done while you are kneeling on a chair with your feet hanging down over the edge of a chair, or lying face down with your feet hanging over the edge of the table, or lying face down with your knee bent up to 90 degrees. While you are in one of these positions, your doctor will squeeze your calf.
What does a positive Silfverskiold test mean?
It measures the dorsiflexion (DF) of the foot at the ankle joint (AJ) with knee extended & flexed to 90 degrees. The test is considered positive when DF at the AJ is greater with knee flexed than extended.
Is Thompson test accurate?
The Thompson test is an accurate clinical test for diagnosing complete Achilles tendon ruptures. However, it might not be a useful test for diagnosing partial Achilles tendon ruptures.
What does a negative Thompson test mean?
When squeezing the right (unaffected) calf, the ankle spontaneously plantar flexed, indicating a negative (normal) Thompson test. Upon squeeze of the left (affected) calf, the ankle did not plantar flex, signifying a positive (abnormal) Thompson test.
How accurate is Thompson test?
The sensitivity of the Thompson’s test for the diagnosis of a complete Achilles tendon rupture is 96-100% and the specificity is 93-100%, but data is limited.
Is the Thompson test reliable?
What is the Thompson test used for?
The Thompson test examines the integrity of the Achilles tendon by squeezing the calf. It is performed as a clinical test to identify the presence of a complete Achilles rupture.
Can a Thompson test be wrong?
A study published in Clinics of Orthopedic Surgery has shown that false-negative Thompson tests account for 25% of neglected Achilles tendon ruptures. According to this study, a false-negative test result may happen when other muscles and tendons still allow plantar flexion in spite of the ruptured Achilles tendon.
What was the result of the Thompson squeezing test?
Thompson and Doherty found that the squeezing test gave a positive result when the m. soleus alone was divided. To elucidate these findings, Scott and colleagues separated the m. gastrocnemius tendon from the m. soleus down to 10 cm above the Achilles tendon, the place where the fibers form the tendon.
What do you need to know about the Thompson test?
Definition/Description. The Thompson test examines the integrity of the Achilles tendon by squeezing the calf. It is performed as a clinical test to identify the presence of a complete Achilles rupture.
How does the Homan’s sign test work for DVT?
In performing this test the patient will need to actively extend his knee. Once the knee is extended the examiner raises the patient’s straight leg to 10 degrees, then passively and abruptly dorsiflexes the foot and squeezes the calf with the other hand. Deep calf pain and tenderness may indicate presence of DVT. [3]
How to check for DVT at home, step by step?
1 Step 1: Actively extend the knee in the leg you want to check. 2 Step 2: Once your knee is in the position, you’ll want someone to help you raise your leg to 10 degrees. 3 Step 3: Have them passively and abruptly squeeze your calf with one hand while flexing your foot with the other. More
