Fig. 2From: The discrepancy in triggered electromyography responses between fatty filum and normal filum terminaleMorphology of fatty filum and normal filum terminale, and the triggered electromyography (EMG) of filum. (A) Morphology of fatty filum under microscopy. (B) Morphology of normal filum under microscopy. (C) Triggered EMG showing no muscle contraction in any monitored channel. (D) Triggered EMG showing EMG response only in anal sphincter. (E) Triggered EMG showing EMG response in muscles of left lower extremity (hamstring, gastrocnemius and peroneus longus). (F) Triggered EMG showing EMG response in muscles of right lower extremity (hamstring, gastrocnemius and peroneus longus) and anal sphincterBack to article page
