Systematic Review of Fire Needling or Warm Needling Treatment for Ankle Sprain

The effectiveness of fire needling or warm needling treatment in clinical studies for the treatment of ankle sprains was reviewed using 4 international (PubMed, Cochrane library, EMBASE, CNKI) and 5 Korean databases (NDSL, RISS, KISS, OASIS, KTKP). Randomized controlled trials, that performed fire needling or warm needling treatment for ankle sprains until October, 2018 were retrieved ( n = 8). All studies were performed in China, and 7 out of 8 studies were published within the last 5 years. There were 4 studies that used fire needling treatment, 3 studies used warm needling treatment, and 1 study used fire and warm needling treatment. The ashi-points and gallbladder meridian were the most frequently selected acupoint and meridian each. All intervention groups in the 8 studies showed statistically significant beneficial effects compared with control groups. The results of this study could provide preliminary data as the basis for welldesigned randomized controlled trials on fire needling or warm needling treatment for ankle sprains.
