Murakami et al. Ear Acupuncture for Immediate Pain Relief – A Systematic Review and Meta-Analysis of Randomized Controlled Trials (2017)

Summary: Ten studies met the authors’ inclusion criteria with six demonstrating auricular acupuncture to be superior to its comparator (e.g. standard care) although the mean difference was small; three showed no difference, and one showed inconsistent results. The authors concluded that, “Ear acupuncture may be a promising modality to be used for pain reduction within 48 hours, with a low side effect profile.”

Macpherson, et al. The persistence of the effects of acupuncture after a course of treatment: a meta-analysis of patients with chronic pain (2017)

Summary: The study aimed to determine the trajectory of pain scores over time using data from 29 high quality randomized controlled trials including 17,922 patients.  The chronic pain conditions included low back, neck and shoulder pain, knee osteoarthritis, and headache/migraine.  Acupuncture versus control resulted in 90% of the benefit still holding one year after end of treatment.  In acupuncture vs. sham control, the sham group improvement diminished by 50% over 12 months whereas the acupuncture group showed no significant reduction.  Patients can therefore be reassured that acupuncture treatment effects persist for chronic pain.

Acupuncture for Chronic Pain: Update of an Individual Patient Data Meta-Analysis
Vickers, Andrew J. et al. The Journal of Pain, 2017 Nov 30. pii: S1526-5900(17)30780-0. doi: 10.1016/j.jpain.2017.11.005.

Summary: Researchers performed a meta-analysis of raw data from 39 randomized controlled trials including 20,827 patients suffering from non-specific musculoskeletal pain, osteoarthritis, chronic headache or shoulder pain.  Acupuncture was superior to both sham and no acupuncture control groups for each pain condition and found clear evidence that the effects of acupuncture persist over time with only a small decrease of approximately 15% over a year.

Summary: This small trial involving 35 patients randomly assigned to receive real electroacupuncture (EA) or sham EA twice a week for 6 weeks before entering a 12-week follow up.  Pain scales, opioid like medication consumption and their side effects were recorded daily.  Participants also completed a number of standardized questionnaires such as the SF-36 at the intervals out to the 20th week.  Reductions in opioid like medications were reduced by 39% in the real EA group and 25% in the sham EA group.  The authors concluded that, “Real electroacupuncture demonstrates promising short-term reduction of opioid like medication for participants with chronic non-malignant pain, but such effect needs to be confirmed by trials with adequate sample sizes.”

Summary: Researchers randomly assigned 41 patients into acupuncture and control groups.  Conventional treatment (rest, NSAIDS, bracing, stretching/exercise) were applied to both groups.  Pain scale and the Duruoz Hand Index (DHI) for functioning of the affected limb, pressure pain threshold, and common extensor tendon (CET) thickness were assessed before and after treatment for both groups. Ten treatments roughly 2 or 3 times a week for 4 weeks were provided to the patients. Both pain and DHI scores in both groups decreased, however the pressure pain threshold and CET thickness only demonstrated improvement in the acupuncture group.  (This is significant in that physicians would be impressed with structural changes due to acupuncture treatment…)  The points used were an ashi point, SJ 5, LU 5, LI 10, LI 11, and LI 4.

Summary: Researchers evaluated 19 randomized controlled trials that compared acupuncture and/or moxibustion with sham acupuncture or another form of acupuncture or conventional treatment.  They considered most of the studies to be of low quality, but demonstrated that acupuncture or moxibustion was superior or equal to conventional treatment such as local anesthetic injection, local steroid injection, NSAIDS, or ultrasound.  The studies showed that acupuncture plus moxibustion were superior to acupuncture alone.

Summary: This meta-analysis evaluated outcomes of randomized controlled trials including pain, physical function, fatigue, sleep, total well-being and stiffness.  Nine trials including 395 participants met the inclusion criteria.  Three studies used electroacupuncture (EA) with the remainder using manual acupuncture.  Low quality evidence from one study (with 13 participants) showed EA improved symptoms at one month following treatment, including pain, well-being, stiffness and fatigue.  There was no difference in sleep quality.  Moderate quality evidence from six studies (286 participants) indicated that acupuncture (EA or MA) was no better than sham acupuncture except for less stiffness at one month.  Low quality evidence from a study with 38 participants showed a short-term benefit of acupuncture over antidepressants for pain relief.  Four studies reported no difference between acupuncture and control or other treatments described at a six to seven month follow-up.  The authors conclude that electroacupuncture is superior to manual acupuncture for pain, stiffness reduction and improvement of global well-being, sleep and fatigue.  The effect lasts up to one month, but is not maintained at six months follow-up.

Summary: Researchers evaluated systematic reviews and meta-analyses of acupuncture in the treatment of headaches and migraines.  For migraine, 22 studies were chosen representing 4985 patients. These meta-analyses demonstrated that acupuncture was associated with statistically significant improvement in both headache frequency and response when compared with routine care only and with prophylactic drug treatment at 2 months. Acupuncture was associated with better response and lower headache frequency at 3-4 months and 5-6 months compared with usual care, but not compared with drug treatment at those time points.  For tension-type headaches, 12 trials met their inclusion criteria representing 2349 patients.  Meta-analyses demonstrated that acupuncture was statistically significantly superior to both routine care and sham acupuncture for both “response” and reduction in the number of headache days at 2 months, 3-4 months, and 5-6 months after randomization.  For chronic headache, Vickers et al. analyzed the raw, patient-level data from 29 RCTs and found that the effect size associated with acupuncture was statistically significantly larger than the effect size associated with sham acupuncture.  The final conclusion of the authors is that, “Those studies provide ample evidence that acupuncture is effective as an adjunct to usual care in the management or prevention of common headache disorders…”

Summary: This paper is an update to a Cochrane review from 2009.  The researchers included RCTs at least 8 weeks in duration that compared an acupuncture intervention with no acupuncture control, sham acupuncture, or prophylactic drug in patients with episodic migraine.  Twenty-two trials included 4985 patients total, and those who compared acupuncture with no acupuncture, acupuncture was associated with a moderate reduction of headache frequency, where 41% of the participants had their migraine frequency cut in half (compared to 17% reduction in those without treatment). Both after treatment (12 trials, 1646 participants) and at follow-up (10 trials, 1534 participants), acupuncture was associated with a small but statistically significant frequency reduction over sham.  After three months headache frequency at least halved in 57% of participants receiving acupuncture and 46% receiving prophylactic drugs and after six months in 59% and 54%, respectively.  The authors concluded that, “The available evidence suggests that adding acupuncture to symptomatic treatment of attacks reduces the frequency of headaches.”

Summary: A total of 270 patients participated in a randomized controlled trial receiving 12 acupuncture treatments over 8 weeks.  The main outcome measure was the difference in number of days with headache between the four weeks before intervention and 9-12 weeks after treatment, as recorded by patients in headache diaries.  The number of days with headache decreased by 7.2 days in the acupuncture group vs. 1.5 days in the wait list group, and 6.6 days in the minimal acupuncture group.  Almost half of those in the acupuncture group had a 50% reduction in number of days with headache.  The authors concluded that, “Acupuncture was more effective than no treatment  but not significantly more effective than minimal acupuncture for the treatment of tension-type headache.”

Summary: Thirty RCTs met inclusion criteria with 25 providing data for meta-analysis (involving 3,109 participants with an average age of 19 years old).  The main outcomes were cure rate, total effective rate, pain intensity, menstrual pain, plasma PGF(2α)/PGE(2) ratio and adverse events.  The results demonstrated that both acupuncture and acupressure, moxibustion and acupoint herbal patches had significant effects compared to medication or non-acupoint stimulation in terms of pain relief, pain intensity, and total effective rate. The acupressure stimulation, moxibustion and/or herbal patches applied to acupoints was more effective compared with acupuncture.  Four studies reported minor adverse events such as bleeding at the needle site, hematoma and needle-site pain.

Summary: The trial consisted of 27 female patients (and 45 wrists) randomly divided into two groups (acupuncture and control). All patients used a night wrist splint.  Pain scale, Duruoz hand index, quick disabilities of the arm, shoulder and hand questionnaire scores, electrophysiologic measurements and median nerve cross sectional areas (CSA) were recorded before and after treatment in both groups.  All indices were improved in both groups, however, the median nerve CSA in the acupuncture group was significantly reduced compared to the control group.  The authors’ conclusion was that, “After acupuncture therapy, the patients with CTS might have both clinical and morphological improvement.”

Summary: Fifty patients with mild to moderate Carpal Tunnel Syndrome (CTS) were randomized into two groups, both receiving night wrist splints for a month, and the acupuncture group was given 8 treatments over a 4 week period. A control group was given 400 mg of ibuprofen three times a day for 10 days.  A month later, significant improvements were found in both groups.  Acupuncture improved all measures compared to ibuprofen, except distal motor latency, and the authors suggest that acupuncture may be an effective treatment for CTS.

Summary: A total of 77 patients were randomly assigned to either a steroid group (prednisolone) and acupuncture group receiving 8 treatments over a four-week period.  Both groups improved at weeks two and four with no statistical significance except the acupuncture group experienced a greater decrease in distal motor latency and nocturnal latency at week four.  The authors’ concluded that, “Short-term acupuncture treatment is as effective as short-term low-dose prednisolone for mild-to-moderate CTS. For those who do have an intolerance or contraindication for oral steroid or for those who do not opt for early surgery, acupuncture treatment provides an alternative choice.”
