Use of Ultrasound in Injections of Botulinum Toxin

ultrasound imaging to guide the intramuscular injections of botulinum toxin : Ultrasound is used to identify the target muscle, and for guiding the insertion of the needle in the muscle. Once the needle is positioned, the botulinum toxin is injected

electrical stimulation (reference technique currently recommended over muscle palpation and anatomical landmarks) to guide intramuscular injections of botulinum toxin. Intramuscular injection is carried out in register with the zone where is located the theoretically target muscle. Electrical stimulation (mediated by the tip of the needle) used to verify the correct position of the needle, and reposition it if necessary. Once the needle is correctly positioned, the botulinum toxin is injected.
