Page 8: Getting To Know The Stimpod (Nms 410/450X)
The STIMPOD NMS 450X is quantitative Neuromuscular Transmission (NMT) Monitor which provides real-time quantitative feedback utilizing tri-axial accelerometry. The Stimpod NMS 410 as well as Stimpod NMS 450X is also a precision nerve locating tool used for localizing specific neural pathways. Localization of nerves by electrical stimulation involves connecting the nerve stimulator to a conducting needle through which local anaesthetics can be injected. -
