Valsalva Test | Rationale & Interpretation

The video tutorial explains the Valsalva test, focusing on its application in diagnosing cervical radiculopathies. It details the procedure, where the patient performs the Valsalva maneuver to increase thoracic and cervical pressure, potentially compressing nerve roots. The test's specificity is high, making it useful for confirming cervical radiculopathy if upper extremity symptoms are reproduced. However, it should be used cautiously, especially in patients with cardiovascular or pulmonary risks. The tutorial emphasizes the importance of interpreting results correctly and understanding the physiological effects involved.
