What is a positive Thompson test?

What is a positive Thompson test?

The feet extend farther than the end of the bed. The examiner then squeezes the calf muscle. This motion, in a normal patient, should cause the toes to point downward as the Achilles pulls the foot. In a patient with a ruptured Achilles tendon, the foot will not move. That is called a positive Thompson test.

Can you diagnose Achilles tear without MRI?

MRI is unnecessary for diagnosing acute Achilles tendon ruptures: clinical diagnostic criteria.

What are 3 special test used for an ankle sprain?

Lateral ankle sprain This study investigated the diagnostic accuracy of three physical examination tests: the anterior drawer test, medial talar tilt stress test, and medial subtalar glide test.

How accurate is the 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.

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.

How do you test ankle stability?

In a clinical setting, the anterior drawer test (ADT) is generally used as a manual test to evaluate ankle instability. The test is usually performed with one hand stabilizing the distal tibia and the other hand pulling the foot anteriorly without any attempt to isolate the displacement from only the tibiotalar joint.

What is the best clinical test for Achilles tendinopathy?

Results: The most valid tests are; pain on palpation of the tendon (sensitivity 84%, specificity 73%, kappa 0.74-0.96) and the subjective reporting of pain 2-6 cm above the insertion into the calcaneum (sensitivity 78%, specificity 77%, kappa 0.75-0.81).

Can the Thompson test be wrong?

What is the Thompson test?

Definition/Description[edit| edit source] 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. Clinically relevant anatomy[edit| edit source]

What is the sensitivity and specificity of the Thompson test?

For the Thompson test, Maffuli23reported a sensitivity of .96 and a specificity value of .93. This led to a LR+ of 13.47 and a LR- of 0.04.

What are the different types of measures used to determine reliability?

measures are used in determining reliability for: 1) speeded and power tests, where a sep­ arately timed short parallel form is admin­ istered in addition to the full-length test; 2) power tests, where a subset of items isim­ bedded within the total test, parallel to the

What is the Thompson test for Achilles tendon rupture?

Achilles tendon rupture. A total of four physical examination tests were reviewed: Thompson test, Matles test, Palpable gap in Achilles tendon, and the Copeland test. For the Thompson test, Maffuli 23 reported a sensitivity of .96 and a specificity value of .93. This led to a LR+ of 13.47 and a LR- of 0.04.
