Percutaneous Cryoneurolysis as a Dynamic Treatment for Spasticity: A Case Series

Abstract

Spasticity, whether from stroke or spinal cord injury or other causes, remains challenging to treat effectively. Common spasticity treatments such as stretching, physical therapy, injection therapy, and even surgery may not result in optimal or the desired outcomes or be appropriate for all patients. Cryoneurolysis is another potential treatment option for spasticity that may have benefits over traditional spasticity treatments. In this case series, 10 patients received cryoneurolysis of specific nerves to treat either lower or upper-extremity pain, weakness, and spasticity, or a neuropathic gait in an outpatient clinic. All 10 patients experienced immediate improvements that were sustained for 1-12 months after treatment. Cryoneurolysis is a safe and effective treatment for spasticity and can allow for easy access to involved nerves.
