Although ultrasound guidance has improved safety, evidence remains limited by small RCTs, heterogeneous protocols, and observational designs. Rigorous multicenter RCTs are needed to confirm efficacy, define patient selection, and standardize protocols. Further research should investigate central regulatory mechanisms and long-term neuroplasticity to advance SGB from empirical therapy to precision intervention.<\/jats:p>\n
