“…result during oocyte aspiration for in vitro fertilization [67] is contrasted by one negative result after third molar surgery [68]. The recently introduced P-Stim auricular EA device offers the advantage of a small size and the possibility to administer the therapy on an ambulatory basis, obviating the need for frequent clinic visits to receive treatments.…”

Acupuncture is now accepted as a complementary analgesic treatment. Auricular acupuncture is a distinct form of acupuncture. Electrical stimulation of acupoints (electroacupuncture) increases the effects of acupuncture. Recently, an auricular electroacupuncture device, the P-Stim, has become available. Clinical studies in outpatients have investigated the P-Stim in chronic musculoskeletal pain and its use for minor surgery. In chronic cervical or low back pain, auricular electroacupuncture was more effective than conventional auricular acupuncture. The results in acute pain were controversial. Auricular electroacupuncture reduced pain and remifentanil consumption during oocyte aspiration when compared with conventional auricular acupuncture or a sham treatment. However, after third molar tooth extraction, auricular electroacupuncture and auricular acupuncture failed to reduce either postoperative pain or analgesic consumption. Further large-scale studies are required to evaluate the analgesic efficacy of auricular electroacupuncture.

“…Wait-list control was most frequently used in earlier RCTs. In a literature search on RCTs published in 2006-2007 [12,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52], most outcomes were positive (Table 1). Needless to say, blinding is impossible with this type of control.…”

“…Indeed, it is difficult to explain why even sham acupuncture shows positive outcomes in RCTs and sometimes leads to greater improvement than physiotherapy or drugs [16]. Based on our own early reports [54] comparing different acupuncture controls for RCTs [12,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][55][56][57][58][59][60][61][62][63][64] on pain, more invasive controls clearly tend to yield more "negative" studies, as wait-list controls produce more positive outcomes (Tables 1, 2, and 3). This result suggests that needle insertion sham may induce a non-specific effect greater than that of placebo, particularly in pain conditions, in which endorphin release may play a major therapeutic role.…”

In recent years, acupuncture has rapidly become part of mainstream medicine in the West, where new developments in acupuncture clinical research show extensive progress in evaluating the efficacy and safety of the modality in many categories of disease, especially in pain conditions. Although challenges and difficulties remain, the acupuncture research community has matured and its past experience may lead to even better methods and more innovative research.

“…However, this study did not include either sham, placebo, or 'no additional treatment' groups. In another trial auricular needle acupuncture with and without electrical stimulation and placebo treatment in patients with third molar extraction did not differ in analgesic consumption or pain reduction [18].…”

The role of acupuncture and transcutaneous-electrical nerve stimulation for postoperative pain control

Evidence of efficacy in recent studies on acupuncture and TENS in management of postoperative pain is limited. However, some high-quality studies clearly show positive results for both methodologies. As these techniques cause no harm, their use as adjunct to conventional pharmaceutical approaches could be considered particularly for patients in whom conventional techniques fail and/or are accompanied by severe medication-related adverse events.
