{{Short description|Muscular reflex}} 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'''.
==Testing== The test is performed by tapping the [[extensor digitorum muscle]] while the fingers are light or half flexed. A sudden contraction of the musculus extensor digitorum and extension of the fingers indicate a normal reflex.<ref>{{YouTube|ezp_wt8YFJE |Extensor Carpi Radialis Longus, Extensor Digitorum Communis Reflex DTR MSR}}</ref>
==Absence of reflex== An absence of reflex can be an indicator for radiculopathy within the C6 and C7 or neuropathy within the [[deep branch of the radial nerve]].
