Analysis of Research Trends in Ultrasound-Guided Acupuncture and Dry-Needling: A Scoping Review.

This study aimed to summarize the current status of research on ultrasound-guided acupuncture and dry-needling treatment and the specific treatment methods applied to patients. A scoping review was conducted, surveying three English databases (PubMed, Embase, and the Cochrane Library) for studies published up to May 2024. All studies related to ultrasound-guided acupuncture and dry-needling treatment were considered. Literature was selected using selection and exclusion criteria, and extracted and organized using EndNote. A total of 107 eligible studies were included. Among the 107 studies, non-comparative studies accounted for the largest proportion (n = 47, 43.9%), followed by randomized controlled trials (RCTs; n = 41, 38.3%). Diseases of the musculoskeletal system or connective tissue (15 diseases of the musculoskeletal system or connective tissue) accounted for most (n = 48, 55.8%) of the 86 diseases studied, followed by symptoms, signs, or clinical conditions not otherwise classified (n = 17, 19.8%). Ultrasound-guided acupuncture and dry-needling have been actively studied and applied for the treatment of various diseases. However, higher-quality studies are needed for further applications in research and clinical practice.
