Myoguide System

Needle EMG Guided Injection System

The Myoguide system is designed to amplify EMG signals from muscle, provide audio feedback and visual signal display to assist clinicians in locating areas of muscle activity. Clinicians can see and hear EMG activity.

Recent studies show that both expert and novice injector needle placements improve with guidance even in large easily accessible muscles.

Treatment delivery supported can be in the form of neuromodulator injections, such as Botox©, Dysport©, and Xeomin©, or as simple as inserting a dry needle electrode.  Myoguide has an integrated two range stimulator that can be used for stimulation location procedures.

Applications support procedures that involve delivery of therapeutic injections for the management of many neurological disorders, such as forms of dystonia, and spasticity, many of which are associated dysfunction and pain.

Stimulation guidance procedures can be carried out, using Myoguide's onboard stimulator, for muscle, nerve location, and motor endplate location.  This is particularly useful support for both chemodenervation and neurolytic procedures.

Myoguide™ is a handheld needle EMG guided injection system. Myoguide™ enables clinicians to see and hear, as well as challenge, the injection sites, before any drug is injected.

Myoguide has an integrated EMG amplifier with 9 gain settings (200, 500, 1000, 1500, 2000, 2500, 3000, 3500 and 4000); an integrated LCD signal display;  high fidelity EMG audio over 10-700Hz bandwidth;  a full size speaker; and a comprehensive integrated stimulator that can stimulate in both 1.0mA and 0.1mA steps over the full 0-20mA stimulation range;  Myoguide has 50, 100, 200, or 500μs stimulation pulse width choices; and stimulation frequency choices of 1, 3, 5, 7, or 10 Hz;

Myoguide also has convenience features such as AUDIO MUTE and STIMULATION PAUSE to help streamline procedures in the clinic.

Myoguide has the most comprehensive features available to clinicians carrying out chemodenervation and neurolytic procedures, in any one portable device.

Myoguide’s 0.1mA step stimulation capability opens up opportunities to use Myoguide more extensively for nerve and motor endplate location procedures. This is especially useful for those using ultrasound, in order to confirm location as part of their guidance procedure.

The Intronix Model 8008 Myoguide™ System 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.
