Pathology in Cervical Dystonia can be associated with "trigger points"(see our whitepaper on trigger points for a great resource).  The trigger point locations are found by physical examination, and manual palpation. They are found to be nodular in nature, or "tight spots" in the muscle. These areas can be marked, after pre-treatment examination, for easy location, once the needle EMG guided injection procedure is ready.

 

It is quite difficult to find the optimal injection locations without Myoguide, as there is a subtlety related to the depths where hyperactive muscle fibers reside. Myoguide allows the clinician to see and hear the EMG signal, providing confirmation that the needle is indeed in the best location.

Another important aspect relates to re-injected sites. Sites injected in previous encounters may still exhibit a degree of neuromodulation. It is of benefit to be able to see the EMG signal, as it provides information about activity that EMG audio alone cannot. The injection dose can be titrated to suit the activity. Hence, we now have a way to evaluate where the optimal injection site is and how much medication is appropriate to inject. This helps to prevent injection of higher volumes and can reduce the concomitant diffusion to adjacent sites.

The video demonstrates the value of Myoguide in finding the injection site, as indicated by a significantly increased level of EMG activity. EMG can be monitored by Myoguide's high fidelity EMG audio, by our large integrated EMG signal display, and by viewing the integrated EMG and EMG RMS indicators on the display screen.

You will also notice the clinician holding Myoguide easily activates the MUTE feature, by pressing the two sideways arrows, as indicated by the pause symbol. This is a very convenient way to shut the audio off while waiting for the next injection. Any button press will switch the EMG audio back to the previously set volume.
