Summary

Intramuscular injections of botulinum toxin are currently the best focal treatment of spasticity, with clearly defined indications and role. French and European recommendations focus on the toxin's mode of administration, which must be as precise as possible. The toxin's specific action on motor endplates (blocking the release of acetylcholine) shows the importance of targeted injections within the muscle belly. The pain caused by these injections is due partly the number of injections (up to 30 in a single session), and partly to the use of electrical stimulation guidance. Prevention and alleviation of the pain caused by these injections have become a regulatory obligation since the law of 4 March 2002 relating to the rights of patients and the quality of the health system (" Any person has the right to receive relief from pain, which must, under all circumstances, be prevented, evaluated, taken into account and treated … ").

Conditions

  • Spasticity

Interventions

PROCEDURE

Ultrasound

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

PROCEDURE

electrical stimulation

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.
