Milgram's test is used to evaluate what type of pain?

Milgram's test is specifically utilized to assess intrathecal pain, which arises from issues within the spinal canal, primarily involving the nerve roots or the spinal cord itself. The test involves the patient lying supine and attempting to raise their legs while keeping them straight, which can provoke pain if there is underlying pathology in the intrathecal space.

This test helps in assessing conditions such as herniated discs or other forms of spinal nerve irritation or compression that lead to intrathecal pain. Positive results typically indicate neurological interference related to the spinal structures, guiding clinicians in further evaluation and management.

The other forms of pain listed—peripheral pain, nerve root pain, and muscle pain—do not directly relate to the specific purpose of Milgram's test, which focuses on the assessment linked to intrathecal conditions.
