Dermatomes are used to represent the patterns of sensory nerves that cover various parts of the body, include, head and neck, upper extremities (arms, hands, torso etc.), and lower extremities (hip, leg, foot, buttocks, feet, etc.)
Is radicular pain neuropathic or nociceptive?
Radicular pain is a type of neuropathic pain. It is defined as pain arising in the back and radiating into the limbs, and is caused by nerve root irritation/inflammation, mainly due to leakage of nucleus pulposus material and/or compression [Zundert et al. 2010].

What does Dermomyotome mean?
Dermomyotome is an epithelial cell layer constituting of the dorsal part of the somite lying under the ectoderm. As its name implies, it will give rise to dorsal dermis and to the skeletal muscle of the myotome, as well as the precursor cells of other skeletal muscles.
Is there a mapping of pain referral patterns?
Although the research discussed today was done many years ago, the finding of the studies has led to the development of an invaluable mapping of pain referral patterns. In particular, the recognition of a “Cloward Sign” is a clinical tool I was given after graduating university and I find it true clinical gem, which I wish to pass on to you.
What is the network map of the nerves?
Network Map of the Nerves. Almost every nerve in your body originally branches out your spine at specific places between the spinal vertebraes. This branching of nerve or the dorsal root from the spine has a particular area of skin that is associated with it. This pattern of skin and associate nerve root is known as the Dermatome pattern.
What patterns of pain are evoked by the first 3 cervical nerves?
We reviewed the patterns of pain evoked by stimulation of the first 3 cervical nerves (C1-C3) in 10 patients with chronic occipital pain, 6 of whom also had migraine. Stimulation at the C1 level evoked periorbital and fro … The cervical nerves may play a significant role in primary headache disorders.
Who developed the pain referral chart for cervical facet joint denervation?
One study conducted by Bogduk (1996) identified the pain referral patterns of cervical facet joints. This information was derived from 61 volunteers who underwent a zygopophyseal joint injection and facet joint denervation in a pain clinic in Japan. They developed this referral chart for clinical use…… (Bogduk, 1996, p. 81).
