Objective:
To evaluate the effects of needling depth on clinical efficacy of lumbar disc herniation (LDH).
Methods:
Ten electronic databases, including China National Knowledge Infrastructure (CNKI), VIP Database, Chinese Biomedical Literature Database (CBM), Wanfang Database, MEDLINE, CENTRAL, CINAHL PLUS, AMED, Embase, PsycINFO, and 6 registry platforms of clinical trials were searched. All randomized controlled trials (RCTs) that compared the effect of needling depth on clinical efficacy of LDH were collected; in addition, the reference lists of the studies included were hand searched. Data were extracted independently by two reviewers. RevMan 5.3 was applied to carry out statistical analysis.
Results:
Totally 8 716 articles were retrieved, and 10 RCTs were included after screening, involving 1 116 patients. The results showed the effects of deep acupuncture onrelievingpain, reducing the Oswestry disability index (ODI), improving total effective rate and Japanese Orthopaedic Association (JOA) were superior to those of shallow acupuncture in patients with LDH.
Conclusion:
It is preliminarily indicated that deep acupuncture is helpful to improve the therapeutic effect of LDH; however, due to the low research quality and small sample size, the evidence is insufficient, and more high-quality researches are needed to further confirm the results.
