A pilot study looking at two different frequencies of treatment by acupuncture for chronic lower back pain, has found that improvements achieved within the first two weeks, were still present at one year follow-up.
Thirty participants with chronic lower back pain were randomly allocated to two groups to receive ten acupuncture treatments: the low frequency group received two treatments per week for five weeks, whilst the high frequency group received five treatments per week for two weeks. No significant differences were found between the groups in terms of measured outcomes, but clinically important improvements in pain, disability and quality of life, were achieved in both groups within the first fortnight, and were maintained at follow-up one year later.
