Extensor digitorum reflex
Encyclopedia
The Extensor digitorum reflex is tested as part of the neurological examination
to assess the sensory and motor pathways within the C6 and C7 spinal nerves. It is also known as Braunecker-Effenberg reflex, or BER.
while the fingers are light or half flexed. A sudden contraction of the musculus extensor digitorum and an extension of the fingers indicates a normal reflex.

Absence of reflex
An absence of reflex can be an indicator for neuropathy within the C6 and C7 or the Deep branch of the radial nerveDeep branch of the radial nerve
The deep branch of the radial nerve winds to the back of the forearm around the lateral side of the radius between the two planes of fibers of the Supinator, and is prolonged downward between the superficial and deep layers of muscles, to the middle of the forearm.Considerably diminished in size,...
