The video tutorial explains the Right Test, also known as the hyperabduction test, used to assess thoracic outlet syndrome. It details the procedure, which involves monitoring the radial pulse while moving the patient's arm into two positions. The test checks for signs like pulse disappearance or familiar symptoms. Positive results indicate compression in specific anatomical spaces. The video emphasizes the importance of monitoring the pulse and interpreting results to identify the source of compression.

How does the position of the patient affect the interpretation of the test results?

What anatomical structures are implicated based on the position where a positive test is found?
