The Neurosign 100 is suited to mastoidectomy and thyroidectomy, the Neurosign 400 to parotidectomy, and the Neurosign 800 to intra-cranial and spinal surgery.
The Neurosign 400 and 800 have a display which can show waveforms. These are extremely useful in determining whether a response is EMG or artifact; the Neurosign 100 only has a bargraph. The Neurosign 400 and 800 also allow you to print out results for inclusion in patient records.
