Multicenter Study of Thermal Radiofrequency Applied to the Musculocutaneous Nerve for the Treatment of Spasticity

This multicenter observational study evaluates the safety and effectiveness of ultrasound-guided thermal radiofrequency applied to the musculocutaneous nerve in adult patients with focal elbow flexor spasticity secondary to central nervous system injury. Hypothesis: Thermal radiofrequency treatment of the musculocutaneous nerve in patients with spasticity resulting from damage to the central nervous system is a safe and effective treatment for spasticity.

Inclusion Criteria: * Signed informed consent. * Age 18 years or older. * Diagnosis of spasticity secondary to central nervous system injury. * Predominant elbow flexor spastic pattern dependent on the musculocutaneous nerve. * Patients with severe spasticity refractory to conservative treatments who underwent thermal radiofrequency treatment of the musculocutaneous nerve during the study period. Exclusion Criteria: * No signed informed consent. * Age under 18 years. * Radiofrequency treatment applied to patients without central nervous system injury. * Absence of follow-up after radiofrequency treatment, for any reason, for a minimum period of 2 months.
