A study undertaken in Milan, Italy shows that acupuncture can accelerate return to consciousness following a general anaesthetic. Fifty patients in recovery were randomly assigned to five groups: acupuncture at one of three point combinations, acupuncture at two sham points, or no acupuncture at all. Signs of recovery appeared faster in patients given true acupuncture compared with those in the sham and no-acupuncture groups. The most effective treatment was a combination of a point on the foot, with a point on the face traditionally considered a “first-aid point” to restore consciousness.

An international study involving Korea, Europe and the US, has revealed that acupuncture stimulation of the point Yanglingquan near the knee, can activate areas of the brain which are known to be impaired in patients with Parkinson’s disease. In a comparison study, twelve patients (mean age 53) with Parkinson’s disease and twelve otherwise matched, healthy individuals, were needled at Yanglingquan whilst brain activity was observed using an fMRI scanner. The patients with Parkinson’s had their usual medication stopped 12 hours before the investigation.

The results showed that acupuncture stimulation had activated the prefrontal cortex, precentral gyrus and putamen in the patients with Parkinson’s; all these areas are known to be impaired in this disease. Furthermore, the characteristics of the activation were different for the two groups, and the patients with Parkinson’s displayed significantly higher post-acupuncture activity in the prefrontal cortex and precentral gyrus.

Researchers using functional MRI scanning have found that acupuncture induces significant connectivity changes in the brains of patients recovering from Bell’s palsy. Previous studies have demonstrated disruption to connectivity between the somatosensory area and other brain regions.

Brain activity was studied in 20 Bell’s palsy patients (aged 19 to 70), and also in 28 healthy subjects (aged 23 to 54). All were given fMRI scans before and after acupuncture at the point Hegu which is frequently included by acupuncturists treating this condition. Acupuncture was found to significantly increase connectivity in the primary somatosensory area, in patients still recovering from Bell’s palsy. Interestingly, there were no such changes in the already-recovered and in the healthy group. The researchers conclude that their findings may begin to shed light on the underlying mechanisms by which acupuncture treats Bell’s palsy.

Researchers in Norway have investigated the correlation between choice of acupuncture points and the recurrence rate of cystitis among women prone to the condition and receiving preventative acupuncture treatment. A total of 58 such women were given acupuncture twice per week for four weeks, the treatments being individualised according to a traditional Chinese diagnosis. They were followed up over a six month period.

The most successful combination of acupuncture points was Shenshu on the lower back and Taixi on the ankle. Women for whom these points were used, experienced only one third of the number of symptomatic cystitis attacks over the follow-up period, compared with women for whom these points were not used. Use of the point Shenshu was associated with a significant reduction in residual urine volume, as measured a few days after treatment.

American researchers have found that acupuncture can improve cardiac function in patients with stable ischaemic heart disease. The trial was accepted for publication in the prestigious International Journal of Cardiology. In a randomized controlled study involving 151 subjects, mean age 63, allocated to receive traditional acupuncture, sham acupuncture or no intervention, they found that heart rate variability during mental stress tests, was higher in the traditional acupuncture group. Heart rate variability has previously been shown to be reduced in stable ischaemic heart disease patients, and this can be associated with sudden cardiac death.

The authors conclude the effect of acupuncture on heart rate variability may be clinically relevant and further work should be done.
