Chemodenervation Clinical Solutions

Ultrasound guidance for chemodenervation procedures

Improve instrumented guidance during chemodenervation procedures with direct and continuous ultrasound. Ultrasound helps visualize and select muscles or other structures for targeting, helps accurately localize the injection target to enhance effectiveness, and minimizes the potential risks and side effects. Color Doppler and Power Doppler help determine flow in vessels in the path to the target.

The goals during chemodenervation procedures are to accurately place the needle within the target structure, avoid structures in the needle path, and avoid structures adjacent to or behind the target structure. Electromyography (EMG), electrical stimulation, ultrasound guidance, and motor endplate targeting all help achieve these goals.

Benefits of needle guidance and e-stim during Chemodenervation

Traditionally guided by clinical examination and anatomic landmarks, the accuracy and safety of chemodenervation injections have been dramatically improved with ultrasound. Electrodiagnostic testing with Sierra Summit electrical stimulation and Sierra NMUS1 ultrasound may enhance the effectiveness of chemodenervation by:

• Visualizing and precisely locating muscles or other structures for targeting
• Accurately localizing the injection target
• Providing muscle activity information
• Minimizing potential risks by avoiding structures in the needle path, and structures adjacent to and behind the target
• Reducing the number of needle sticks
• Helping to place the needle in the target muscle or adjacent to the target nerve for motor point localization or nerve blocks

Using Sierra NMUS1 ultrasound for guided injections can help improve clinical outcomes, enhance patient safety, and save procedural time. Diagnostic, neurolytic, and anesthetic nerve blocks or motor point blocks are typical use cases for this combination, as well as for patients with complex postures associated with cervical or limb dystonia.

Clinical indications for ultrasound-guided needle injections

Combined techniques with Sierra electrodiagnostic solutions can be used to treat spasticity and function in individuals with spinal cord injuries, and to improve muscle activity in movement disorders like dystonia, tremors, and hemifacial spasms.
