Myoguide Applications:  New Series Pt. 3

This is the third post, in our new series, that recognizes Myoguide application, used to manage spasticity, in scientific publications

We do try to keep track of the many references citing Myoguide use as an essential part of research based publications. This is part of our ongoing surveillance needed and our responsibility maintaining our medical device licences. The following series will feature these articles, to help illustrate the various benefits of using Myoguide in practice and for research applications.

Single-fiber Electromyography Examination in Patients Treated with Botulinum Toxin

There have been many journal articles written within the realm of Botulinum Toxin applications that cite “Myoguide” use as part of the studies. This article hails out of:

Ankara Numune Training and Research Hospital, Clinic of Clinical Neurophysiology, Ankara, Turkey

The aim of this study was to evaluate the functions of neuromuscular junctions in muscles that were injected botulinum toxin and in muscles that were not injected botulinum toxin after the expected duration of effect of botulinum toxin passed in patients who received botulinum toxin therapy.

For the treatment of Cervical Dystonia, Btx-A was injected to hyperactive muscles using 26 gauge, 50 mm-long needles accompanied by the Myoguide™ EMG/ESTIM BoNT injection guidance system.

Muscles injected: Sternocleidomastoid, Semispinalis Capitis, Splenius Capitis, Levator Scapula, Trapezius, and Scalenus. The choice of muscles was made under the guidance of an EMG device for each patient.

In this study, subclinical neuromuscular junction dysfunction was not detected in muscles without toxin injections during the period when the clinical effect of the toxin had passed in patients treated with botulinum toxin therapy. Therefore, it is important to keep in mind that neuromuscular junction dysfunction detected in distant muscles that have not been directly injected BtxA may be part of pseudobotulism.

Their conclusion was that, in patients treated with botulinum toxin, neuromuscular junction defects were not detected in the muscles in which the toxin was not injected directly.

Myoguide on a table

You can always rely upon Myoguide for reliable EMG/STIM injection guidance.

We posted an article detailing how the Myoguide™ EMG/ESTIM BoNT Injection Guidance System Improves Needle Placement

The article presented a short review of the benefits of using the Myoguide™ EMG/ESTIM BoNT injection guidance system, citing appropriate literature.
