Needle acupuncture in tension-type headache: a randomized, placebo-controlled study.

Area of Science:

• Neurology
• Complementary and Alternative Medicine

Background:

• Tension-type headache is a common neurological disorder.
• Acupuncture is a frequently used complementary therapy for headache management.
• The efficacy of acupuncture for tension-type headache requires rigorous evaluation, particularly with effective placebo controls.

Purpose of the Study:

• To investigate the effectiveness of verum needle acupuncture compared to a novel placebo acupuncture technique in patients with tension-type headache.
• To assess the impact of acupuncture on pain intensity, headache frequency, and quality of life.

Main Methods:

• A randomized controlled trial was conducted with 69 patients diagnosed with tension-type headache.
• Participants were randomly assigned to receive either verum acupuncture or a placebo acupuncture.
• Outcomes including visual analogue scale for pain, headache frequency, and quality of life measures were assessed immediately, at 6 weeks, and 5 months post-treatment.

Main Results:

• No statistically significant differences were found between verum and placebo acupuncture regarding pain intensity (visual analogue scale) and headache frequency at any assessment point.
• A significant, albeit weak, improvement in quality of life parameters (clinical global impressions, Nottingham Health Profile) was observed following verum acupuncture treatment.
• Decision tree analysis indicated that improvements in clinical global impressions and headache frequency were dependent on baseline headache frequency (≤24.5 days/month), and higher depression scores correlated with higher pain intensity.

Conclusions:

• This study suggests that needle acupuncture, when compared to a specific placebo procedure, does not provide superior therapeutic benefits for the primary endpoints of pain intensity and headache frequency in tension-type headache.
• Acupuncture may have a modest positive effect on quality of life, but this finding requires further investigation.
• Patient-specific factors, such as headache burden and depressive symptoms, may influence treatment outcomes.
