What is a Lumbar Dermatome Map?

A dermatome map is a guide practitioners utilize to identify the affected dermatome based on the patient’s symptoms. A , in particular, focuses on the dermatomes and spinal nerves located in the lower back region.

To help you out, here’s a list of the lower back region’s spinal nerves and their corresponding dermatomes.

  • L1: lower back, upper hips, and groin
  • L2: lower back, hips, and tops of the inner thigh
  • L3: lower back, inner thighs, and inner legs below the knees
  • L4: the back of the knees, inner sections of the lower legs, and the heels
  • L5: top of the feet and front of the lower legs

As for the map, we noticed the existence of a handful of dermatome map templates, but templates of lumbar dermatome maps are few and far between. That’s why we’ve created a lumbar dermatome map template to help practitioners who want to focus on checking the patient’s lower extremities and affected dermatomes or spinal nerves in the lower back region. Our template can reduce the risk of practitioners getting distracted or confused by the other regions and places a premium on finding the localized lesion in the area.

You can opt to do the light touch test with a ball of cotton wool on the concerned area, or you can also do the pinprick test by pricking the area with a pin and asking the patient if they feel a sharp or blunt sensation. Don’t forget to ask for sensory symptoms from the patient so you have a more concrete idea of what the patient is experiencing. 

Step Three. Fill out the Template

Research & Evidence

Though there are multiple studies and evidence that prove that dermatome maps aren’t the best tools practitioners can use due to their inconsistencies across guides/templates and on a person - since the location of a particular dermatome area may vary a bit depending on the patient’s body - according to Downs and Laporte, sensory skin tests are still a valuable and “important tool for identifying the location of a neurological injury”. Therefore, it’s recommended that practitioners continue using lumbar dermatome maps but take its results with a grain of salt and do further testing before formulating a clinical impression or final diagnosis.
