MacKenzie’s sign

MacKenzie’s sign is used by healthcare providers to identify nerve root compression, especially in the lower back. It involves asking the patient to extend their leg while lying on their stomach. If this movement causes pain that radiates down the leg or back, it suggests nerve involvement. Essentially, the test helps determine if a pinched nerve is causing symptoms. It is a clinical tool to assess low back pain and nerve irritation, aiding in diagnosis and guiding further treatment strategies.
