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.
