The intramuscular injection of botulinum toxin in targeted muscles has emerged as a treatment of choice for the management of spasticity, as well as for numerous other conditions. An essential factor influencing the treatment outcome is the need for better accuracy in delivering the toxin to the target muscle. The needle must be positioned within…

Basic EMG Signal Pick-Up There are three electrodes used for EMG guidance procedures: a surface reference electrode a surface ground electrode a hypodermic needle electrode This is the basis of what is required to measure a usable biosignal using a differential amplifier to improve the quality of the signal by subtracting out the common mode…

There are many compelling reasons to use EMG guidance. The first is that EMG ensures that the needle is located in a muscle and in a muscle that is actively contracting in association with the disorder. Speelman and Brans showed that even the most experienced “blind” injectors were frequently inaccurate in identifying needle placement in…

Myoguide™ EMG/ESTIM BoNT injection guidance system is designed to amplify EMG signals from muscle and provide audio and visual feedback to assist clinicians in locating areas of muscle activity. Myoguide also has an integrated and well featured stimulator, capable of stimulation in either 1.0 mA or 0.1 mA steps, for muscle, nerve, and motor endplate location procedures. Myoguide supports…
