Abstract: Apparatus for use in nerve conduction testing where a stimulating electrode is used to electrically stimulate a nerve and a detection electrode is used to detect an evoked neurological response, the apparatus comprising: a shaped protrusion for positioning against an electrode; and a compression mechanism for applying a force to the shaped protrusion so as to cause the shaped protrusion to press the electrode against the underlying tissue and compress the same, so as to move the electrode closer to the nerve and thereby augment nerve stimulation and response detection.
