Researchers in Japan have found acupuncture to be superior to the injection of local anaesthetic for the treatment of lower back pain. Twenty-six patients were randomly allocated to receive either acupuncture or local anaesthetic injection at two to five of the most painful points on the lower back, once per week for four weeks. Both groups experienced pain relief, but acupuncture provided significantly more pain relief at all time points measured, including at two and four weeks after completion of treatment.
The authors of the study conclude that both injection and acupuncture relieved pain, but acupuncture was superior for the immediate and sustained effects, suggesting that it is a useful treatment for lower back pain. The difference in the effects may be attributable to differences in the mechanism of pain suppression.

Japanese university researchers have examined the effects of acupuncture for lower back pain, and related mood disturbances and medical expenses, among employees of a steel firm.
Acupuncture was given once a week to 72 workers, averaging 53 years in age. After eight weeks of treatment, patients reported less pain and a significant decrease in mood disturbance. There were also significant reductions in the number of visits to hospital for conventional care, and in medical expenses related to lower back pain. The authors say we can expect wide-ranging economic effects if acupuncture treatment were to be introduced into companies.

An audit of almost 6000 patients who attended a pain clinic in Spain over a nine year period, revealed an average success rate of 79.7%. For the audit, “success” was defined as an improvement of at least 50% in five factors: pain intensity, pain frequency, consumption of painkillers, level of incapacity, and sleep disturbance.
The highest success rate (93%) was achieved in patients with headaches. The authors conclude acupuncture is effective, carries with it no severe adverse events, and considerably reduces the consumption of analgesic and anti-inflammatory drugs.
