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…

While the Myoguide System is better known for being a world class, EMG/STIM BotNT injection guidance system, the USFDA classification includes “Electrical Peripheral Nerve Stimulator”.   We can underline the fact that Myoguide has a very well featured, integrated stimulator designed for both nerve and muscle stimulation.  In fact, it is Myoguide’s capability of being continuously…

Myoguide input cable EMG and STIM guidance procedures require a quality hypodermic needle electrode and two surface electrodes. The needle electrode plugs into Myoguide’s black connector. One surface electrode is connected to the green connector and is for the ground, and the other connects to the red connector and is for the reference. I heard the…

Even though the NiMH rechargeable batteries have a lower specified capacity (2300mAH) and lower voltage (1.2V) compared to a typical Duracell ProCell Alkaline AA battery (2850mAH, 1.5V), they tend to provide more capacity in a higher current draw situation. The following article covers Myoguide Battery Strategies to get the longest battery life. NiMH rechargeable batteries…

We would like to review Myoguide electrode Strategies for Optimizing EMG/ESTIM BoNT Injection Guidance Results. We have been received quite a few inquiries about what the optimal surface electrode placement approaches should be for procedures involving injection guidance using hypodermic needle electrodes and Myoguide EMG/ESTIM BoNT injection guidance system. Firstly, I would like to refer…

Hands- On: Learning to Use Myoguide The following steps can be used to learn and verify functionality of the Myoguide device. For first time users, it is a good idea to play with Myoguide on your own, before engaging patients.  These exercises will help you learn about measuring EMG and delivering stimulation on your own…

Motor point chemodenervation or chemical neurolytic procedures require low current stimulation location in the order of 0.2-0.5 mA, depending on the stimulation pulse width.  Pulse width is an essential part of the stimulation delivery.  Narrower pulse widths deliver the current pulse over the duration of the pulse width.  This means that the energy delivered is short for short…
