How to do dermatome testing?

Dermatome testing assesses sensory function by evaluating the skin's response to stimuli in specific areas innervated by particular spinal nerves. To perform the test, use a cotton swab, pinprick, or temperature stimuli to gently touch the skin in designated dermatome regions. The patient should report sensations, noting any areas of decreased or absent feeling. Results can help in diagnosing neurological conditions or determining the level of spinal cord injuries.
