Effect of needle selection on battlefield acupuncture tolerance and pain reduction: an exploratory randomized controlled trial.

Researchers conducted a study comparing three different types of needles used in battlefield acupuncture (BFA), a specific ear acupuncture technique designed for pain relief. The study included 30 patients experiencing acute or chronic pain, who were randomly assigned to receive treatment with ASP needles, 15-millimeter disposable needles, or Pyonex needles. The main goals were to determine whether certain needle types were better tolerated and whether they differed in pain-reducing effectiveness.

The results showed that all three needle types significantly reduced pain across multiple measures, with improvements noted immediately after treatment and continuing for up to one week. However, the 15-millimeter needles caused less pain at the insertion site compared to ASP needles, making them more comfortable during treatment. The Pyonex needles showed similar insertion pain to ASP needles. Importantly, there were no differences between needle types in terms of overall patient satisfaction, side effects like dizziness, bruising, fatigue, or headaches.

For patients considering battlefield acupuncture for pain management, this study suggests that all three needle types can effectively reduce pain, though some may be more comfortable than others during insertion. The choice of needle type may depend on individual sensitivity and practitioner preference, as all appear to deliver similar pain relief outcomes. This exploratory study helps establish that comparing different acupuncture needles is feasible and provides groundwork for larger future studies.

This unblinded exploratory RCT (n=30) compared three needle types for auricular battlefield acupuncture in acute and chronic pain patients: ASP needles, 15mm disposable needles, and Pyonex needles (10 per group). Outcomes were assessed using the Defense and Veteran Pain Rating Scale (DVPRS) and needle tolerance questionnaires at baseline, 10 minutes, 24 hours, and 1 week post-treatment. The 15mm needles demonstrated superior tolerance with significantly lower pain at insertion sites compared to ASP needles (OR=0.12, p=0.005), while Pyonex showed no significant difference (OR=1.45, p=0.525). No differences in overall satisfaction or adverse effects were observed between groups (p=0.190). DVPRS scores significantly declined post-treatment across all groups (β=-1.40, p<0.001), with sustained improvements for specific DVPRS questions but not overall scores over time. All three needle types demonstrated comparable analgesic efficacy. The study establishes feasibility for comparative needle research and provides power calculations for future definitive trials.
