The Research Behind Our Care
This library collects every scientific study cited across our condition pages. Each entry is verified against PubMed, graded by study type, and summarized in plain language — including where the evidence is strong and where it is limited. We summarize the research as it stands; we don’t cherry-pick.
Each study links to the condition pages that cite it, so you can see the evidence in the context of the care it informs.

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
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.

Systematic Review · Meta-Analysis
Effectiveness of Acupuncture on Anxiety Disorder
Pooling 20 randomized controlled trials with 1,823 participants, this review found acupuncture more effective than control conditions for reducing anxiety symptoms (standardized mean difference −0.41), with a favorable safety profile across the included trials. While this page focuses on stress and tension broadly, the research base on acupuncture for anxiety specifically is part of the same evidence picture.

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.

Systematic Review · Meta-Analysis
Effectiveness of Acupuncture for Lateral Epicondylitis
Pooling 10 randomized trials (796 participants), this review found acupuncture outperformed sham acupuncture, medication, and blocking therapy on overall clinical efficacy for lateral epicondylitis — while the authors noted trial quality varied and called for larger, more rigorous studies.

Clinical Guideline
ACR / Arthritis Foundation Osteoarthritis Guideline
This joint American College of Rheumatology and Arthritis Foundation guideline conditionally recommends acupuncture for patients with knee, hip, and/or hand osteoarthritis, citing its potential benefit for pain and its low risk of harm while acknowledging that the certainty of the evidence is limited.

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.

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.

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.

Systematic Review · Meta-Analysis
Manual Acupuncture for Myofascial Pain Syndrome
Pooling 10 randomized trials, this review found a favorable effect on pain intensity specifically when acupuncture needling targeted the myofascial trigger point itself (standardized mean difference −0.90 vs. sham) — notably, the same benefit was not seen when needling generic acupuncture points instead, underscoring the value of precise trigger-point localization.

Systematic Review · Meta-Analysis
Acupuncture for the Treatment of Peripheral Neuropathy
Across 15 studies, most randomized trials favored acupuncture over control for several neuropathic conditions including carpal tunnel syndrome; a pooled analysis of related nerve-compression data (6 trials, 680 patients, covering diabetic neuropathy and Bell’s palsy) showed an odds ratio of 4.23 favoring acupuncture. The authors concluded acupuncture shows promise for some neuropathies but that larger, sham-controlled trials specific to carpal tunnel are still needed.

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.

Randomized Controlled Trial
High- and Low-Level Laser Therapy for Bell’s Palsy
In a small 48-person trial, laser groups improved more than the exercise-and-massage-only group. The study was small, used specific laser devices and protocols, and does not establish that every LED or phototherapy device produces the same result.

Clinical Practice Guideline
Clinical Practice Guideline: Bell’s Palsy
The guideline strongly recommends oral steroids within 72 hours for eligible patients and eye protection when eye closure is impaired. It makes no recommendation for or against acupuncture or physical therapy because the evidence was insufficient.

Cochrane Systematic Review
Physical Therapy for Bell’s Palsy
Low-quality evidence suggested tailored facial exercises may help some patients, particularly in chronic cases, but the review found insufficient high-quality evidence to determine the effectiveness of physical therapies overall.

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.
