BACKGROUND: Extracorporeal shock wave therapy, as its potential benefits for various musculoskeletal diseases, has received widespread attention. Increasingly studies have demonstrated that it has excellent effects such as pain relief and functional recovery. However, bibliometric analysis in the domain of extracorporeal shock wave therapy for pain is relatively lacking. OBJECTIVE: To visually analyze the studies related to extracorporeal shock wave therapy for pain and to sort out the knowledge structure and explore its research status as well as hot trends in this field at home and abroad. METHODS: The publications related to extracorporeal shock wave therapy for pain from 2002 to 2022 in Web of Science Core Collection database and CNKI database were searched. Visual analysis using Citespace software was performed to produce the diagrams and interpret their meanings. RESULTS AND CONCLUSION: A total of 2 101 studies were included. The number of documents issued showed a fluctuating upward trend and the United States and China had certain advantages in the number of documents issued. The issuing institutions are mainly universities and hospitals and the issuing authors mostly belonged to independent teams. The exchange between issuing institutions and authors needed to be strengthened and the degree of crossinstitutional and cross-regional cooperation was low. Keyword visual analysis indicated that extracorporeal shock wave therapy has been widely used in musculoskeletal diseases and further studies should focus on multidisciplinary in-depth study and observation of the clinical efficacy of combined therapy. The studies on the topic of extracorporeal shock wave therapy treating pain mainly focus on musculoskeletal diseases, including plantar fasciitis, scapulohumeral periarthritis, and tennis elbow. In recent years, combined treatment with ultrasound-guided injection therapy, traditional Chinese treatment techniques and expansion of new fields become research trends and hotspots of concern.

This study aims to determine whether ESWT (extracorporeal shock wave therapy) affects ONFH (osteonecrosis of femoral head) in clinical outcomes and radiography outcomes. Two authors independently search the papers on the treatment of femoral head necrosis with extracorporeal shock wave in CNKI (China National Knowledge Infrastructure), VIP (China Science and Technology Journal Database), CSPD (China Science Periodical Database), Pubmed, Embase, and Springer databases. Search period from the inception dates to 2 June 2020 and have no limitations in language; two authors independently conducted a quality evaluation and data extraction for included studies and performed a meta-analysis with data extracted and calculate by using RevMan5. Registration number: CRD42020213580. Nine articles with 409 patients are included in this meta-analysis. The pooled results of HHS (Harris hip score) in eight studies with 337 hips show that ESWT achieves higher Harris scores compared to before treatment (MD = −19.95; 95% CI: −26.27, −13.64) and the difference is statistically significant (p < 0.01). The pooled results of VAS (visual analogue score) in seven studies with 253 hips show that ESWT achieves lower VAS compared to baseline (MD = 2.77; 95% CI: 1.88, 3.65) and the difference is statistically significant (p < 0.01). The pooled results of lesion of MRI with 164 hips show that ESWT decreases the lesion area of MRI (SMD = 1.03; CI: 0.75,1.30) and the difference is statistically significant (p < 0.01). ESWT has an effect on pain relief and has a limited effect on motion function. Its effect may be better than surgical groups (core decompression and core decompression with bone grafting). But it cannot decrease the lesion area of the femoral head on MRI and stop disease progression. [ABSTRACT FROM AUTHOR]
