Pulsed Radiofrequency for Post-Stroke Complications: From Neuromodulation to Functional Recovery.

Abstract

Purpose of review This review synthesizes the mechanisms, applications, and evidence gaps regarding pulsed radiofrequency (PRF) in the rehabilitation of post-stroke complications to guide its standardized integration. Recent findings PRF, a minimally invasive neuromodulation technique, modulates neuronal excitability without thermal damage. Emerging evidence highlights multi-target effects, including improved microcirculation, suppressed neuroinflammation, and regulated neurotrophic factors. Clinically, PRF effectively alleviates refractory post-stroke pain and may indirectly ameliorate post-stroke depression while facilitating motor recovery. Image-guided procedures targeting specific nerves demonstrate favorable safety profiles. Despite promising outcomes for stroke rehabilitation, current evidence relies primarily on small case series and preclinical studies. Significant gaps remain in standardized protocols and high-quality randomized controlled trials. Further validation of long-term efficacy and safety is essential to establish PRF's definitive role in comprehensive post-stroke management.
