Randomized Trial
JAMA Internal Medicine Sham-Controlled Trial — Chronic Sciatica From Herniated Disk
In 216 patients with chronic sciatica from a herniated disc, 10 acupuncture sessions over 4 weeks reduced leg pain roughly twice as much as sham acupuncture (a 30.8 vs 14.9 point drop on a 100-point scale) and improved function significantly more. Benefits appeared by week 2, persisted through a full year, and no serious adverse events occurred.

Meta-Analysis
Durable Effects of Acupuncture for Chronic Neck Pain — 18 trials
Pooling 18 randomized trials, acupuncture added to other care provided pain relief lasting at least 3–6 months after treatment ended, and improved function significantly more than sham acupuncture at 3 months. On pain scores alone, acupuncture did not outperform sham — an honest limitation the authors report alongside a favorable safety profile.

Randomized Trial
Acupuncture for Diabetic Peripheral Neuropathy — ACUDPN Trial
In this open-label randomized trial of 62 patients with type 2 diabetic neuropathy, the acupuncture group reported numbness improved by about 2.3 points on an 11-point scale versus a waiting-list control, with benefits persisting at 16 and 24 weeks; objective nerve-conduction measurements did not change. The authors call for confirmatory sham-controlled studies.

Randomized Trial
Intensive Acupuncture vs Sham for Knee Osteoarthritis (Tu et al.)
In this multicenter sham-controlled trial, intensive electroacupuncture produced a higher response rate at 8 weeks than sham (60.3% vs 47.3%), with benefits lasting through 26 weeks; manual acupuncture, however, was not significantly better than sham at 8 weeks — a clear reminder that results can vary by technique.

Cochrane Review
Cochrane Systematic Review — Chronic Nonspecific Low Back Pain
Compared with no treatment, acupuncture produced clinically relevant pain relief (moderate-certainty evidence), and compared with usual care it improved function and quality of life. Differences versus sham acupuncture were smaller and fell below the review’s threshold for clinical importance.

Randomized Trial
Acupuncture for Chemotherapy-Induced Peripheral Neuropathy (Bao et al.)
In this pilot randomized trial of 75 cancer survivors with moderate-to-severe chemotherapy-induced neuropathy, real acupuncture produced significantly greater reductions in pain, tingling, and numbness at 8 weeks than usual care. The difference versus sham acupuncture was smaller, and the authors describe the study as preliminary — designed to inform a larger, definitive trial.

Meta-Analysis
Acupuncture for Chronic Pain — 39 trials, 20,827 patients
Across 39 high-quality randomized trials, acupuncture was superior to both sham acupuncture and no-acupuncture controls for chronic back and neck pain. Treatment effects persisted over time and could not be explained by placebo alone.

Meta-Analysis
Acupuncture for Lumbar Disc Herniation — 30 trials, 3,503 participants
Pooling 30 randomized trials, acupuncture produced higher overall effectiveness rates than lumbar traction, ibuprofen, diclofenac, and meloxicam, and better pain scores than traction and diclofenac. An important caveat: the comparators were traction and medication rather than sham treatment, and the authors noted that more rigorously designed, large-scale trials are still needed.

Systematic Review
Systematic Review — Acupuncture for Rheumatoid Arthritis
Reviewing 43 studies, the authors reported that acupuncture alone or alongside conventional treatment may help improve function and quality of life in rheumatoid arthritis, with no adverse effects reported — while candidly noting inconsistent efficacy results and a shortage of well-designed trials. RA evidence remains adjunctive.

Clinical Guideline
American College of Physicians — Low Back Pain Guideline
The ACP recommends acupuncture as a first-line, non-drug treatment for chronic low back pain — to be tried before medication — and as a treatment option for acute low back pain.

Systematic Review
Acupuncture for Peripheral Neuropathy — Systematic Review & Meta-Analysis
Across 15 studies, most randomized trials favored acupuncture over control for diabetic neuropathy, Bell’s palsy, and carpal tunnel syndrome; a pooled analysis of diabetic neuropathy and Bell’s palsy data (6 trials, 680 patients) showed an odds ratio of 4.23 favoring acupuncture for neuropathic symptoms. The authors concluded acupuncture is beneficial in some neuropathies but that larger sham-controlled trials are still needed.

Randomized Trial
JAMA Internal Medicine — Long-Term Migraine Trial
In 249 patients with migraine without aura, true acupuncture reduced monthly migraine attacks significantly more than sham acupuncture or a waiting-list control (a reduction of about 3.2 attacks per month versus 2.1 and 1.4, respectively), and the benefit persisted through 24 weeks of follow-up.

Clinical Guideline
EULAR — European Fibromyalgia Management Recommendations
This evidence-based European guideline gave acupuncture a conditional (“weak for”) recommendation for fibromyalgia based on evidence of pain improvement, while strongly recommending exercise as core therapy — supporting the combined movement-plus-treatment approach we use.

Cochrane Review
Cochrane Review — Acupuncture for Migraine Prevention
Across 22 trials with 4,985 participants, adding acupuncture reduced the frequency of migraine attacks, with a small but genuine effect beyond sham needling. Acupuncture performed at least as well as preventive drug treatment in comparative trials, with fewer reported side effects.

Cochrane Review
Cochrane Review — Acupuncture for Tension-Type Headache
In 12 trials with 2,349 participants, 51% of acupuncture patients achieved at least a 50% reduction in headache frequency versus 43% with sham needling, and effects compared with routine care alone were larger. The authors concluded acupuncture is effective for frequent episodic or chronic tension-type headaches, while calling for more trials against other active treatments.

Meta-Analysis
Acupuncture for Sciatica — 12 trials, 1,842 participants
Pooling 12 randomized trials, acupuncture outperformed conventional Western medication on overall effectiveness, pain intensity, and pain threshold, and the authors concluded acupuncture may be effective for the pain associated with sciatica. A design limitation worth noting: most included trials compared acupuncture with medication rather than sham — a gap the 2024 JAMA trial above helped address.

Cochrane Review
Cochrane Review — Acupuncture for Fibromyalgia
Across nine trials with 395 participants, low-to-moderate certainty evidence showed acupuncture improved pain and stiffness compared with no treatment and standard therapy, while differences versus sham acupuncture were not significant for pain or fatigue. Electroacupuncture appeared more helpful than manual needling — an honest picture of a genuinely mixed evidence base.

Randomized Trial
German Randomized Acupuncture Trial for Chronic Shoulder Pain (GRASP)
In this trial of 424 patients with chronic shoulder pain, 65% of those receiving Chinese acupuncture met the response criteria three months after treatment, compared with 24% for sham acupuncture and 37% for conventional orthopedic care — a statistically significant advantage for acupuncture over both comparisons.

Randomized Trial
GERAC Trial — 1,162 patients, one of the largest back-pain RCTs
After 6 months, 47.6% of acupuncture patients met the response criteria versus 27.4% receiving guideline-based conventional care (medication, physical therapy, and exercise) — nearly double the response rate.

Randomized Trial
Charité Routine-Care Trial — 14,161 Neck Pain Patients
In one of the largest neck pain studies ever conducted — 14,161 German patients in everyday practice settings — adding up to 15 acupuncture sessions to routine care improved neck pain and disability significantly more than routine care alone at 3 months, and the improvement was essentially maintained at 6 months.

Cochrane Review
Cochrane Systematic Review — Acupuncture for Shoulder Pain
This Cochrane review of 9 varied trials concluded that, because the studies were few and methodologically diverse, there was little evidence to firmly support or refute acupuncture for shoulder pain — though it noted possible short-term benefit for pain and function. The authors emphasized the need for better-designed trials.
