The video tutorial explains carpal tunnel syndrome, focusing on the compression of the median nerve. It introduces two clinical tests: Tinel's sign, which involves tapping over the median nerve to elicit symptoms, and Phalen's sign, which involves holding the wrists together to reproduce symptoms. Both tests help diagnose carpal tunnel syndrome by identifying symptoms like numbness and tingling in the median nerve distribution. The video concludes with a call to action for viewers to engage with the content.
