Testing of myotomes, in the form of isometric resisted muscle testing, gives information about the level in the spine where a lesion may be present. The exact area that each dermatome covers can be different from person to person. A myotome is a group of muscles innervated by the ventral root a single spinal nerve. A myotome is defined as a distribution of musculature that is innervated by a given segmental motor nerve. Hip extension means you’re opening, or lengthening, the front of your hip.
