Acupuncture analgesia involves modulation of pain-induced gamma oscillations and cortical network connectivity.

Recent studies support the view that cortical sensory, limbic and executive networks and the autonomic nervous system might interact in distinct manners under the influence of acupuncture to modulate pain. We performed a double-blind crossover design study to investigate subjective ratings, EEG and ECG following experimental laser pain under the influence of sham and verum acupuncture in 26 healthy volunteers. We analyzed neuronal oscillations and inter-regional coherence in the gamma band of 128-channel-EEG recordings as well as heart rate variability (HRV) on two experimental days.

Immediate Pain Relief in Adhesive Capsulitis by Acupuncture-A Randomized Controlled Double-Blinded Study.

Objective: Primary adhesive capsulitis (AC), or frozen shoulder, is an insidious and idiopathic disease. Severe pain is predominant in the first two of the three stages of the condition, which can last up to 21 months.

Design, Setting, And Subjects: Sixty volunteers with primary AC were randomly assigned to acupuncture with press tack needles compared with press tack placebos in a patient- and observer-blinded placebo-controlled study.
