Thompson Test | Rationale & Interpretation

The video tutorial explains the Thompson test, a diagnostic tool for Achilles tendon ruptures. It details the procedure, where the patient lies prone with feet dangling, and the examiner squeezes the gastrocnemius to observe plantar flexion. A lack of movement indicates a positive test, suggesting a complete rupture. The test's psychometrics show high specificity and sensitivity. The video also discusses interpreting results for partial ruptures, which may still show movement but can be painful.

Explain the significance of specificity and sensitivity in the Thompson test.

How can the results of the Thompson test be interpreted in relation to grade 1 and grade 2 strains?
