Myoguide Back Muscle Demo
Myofascial pathology is often 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 are marked 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. Once more, 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.

Benefits
• Myoguide provides a superior injection site targeting system with many useful features, such as, the ability to see and hear EMG signals, display real time analyzed EMG, and stimulation location capability.• Myoguide provides both quantitative and qualitative feedback necessary for clinicians to make decisions about treatment and treatment delivery. All these features are wrapped up in a small , battery operated, hand-held device.
• Myoguide helps identify involved muscles through pre-injection, or pre-intervention evaluation. This can be done by either EMG evaluation, or stimulation location, and is particularly useful in cases where the site may be surrounded by essential nerves and blood vessels
• Pre-injection evaluation can lead to use of reduced drug dose and volume, thereby contributing to limiting drug diffusion into adjacent areas. This is especially pertinent in cases where drugs will be re-injected on follow up appointments, as the basal EMG activity level can be assessed before a dose decision is finalized.
Improve Efficacy
The need to increase accuracy when injecting neuromodulators has been highlighted by recent FDA reviews of the dangers of peripheral effects. Use of Myoguide can lead to more accurate injection site targeting, allowing reduced concentrations and volumes of injected drugs.
