The use of neurolytic blocks for the management of spasticity

The management of spasticity often requires a combination of methods to maintain normal range of motion and improve functional capacity. Most practitioners are familiar with the use of systemic spasmolytic agents, stretching, and splinting but may be less likely to consider anesthetic or neurolytic neural blockade for management of spasticity in a localized fashion. In this article, both historical perspectives and new techniques of neural blockade are discussed. Information presented includes indications for use, choices for medication and site of injection, duration of therapeutic effect, and adverse effects. The goal of the article is to provide a rational, integrated analysis for the inclusion of peripheral neural blockade and intramuscular neurolysis in the treatment of spasticity.
