Abstract: A controlled study of different modes of acupuncture stimulation was
conducted on patients fulfilling clinical criteria for chronic low back
pain of nociceptive origin. Forty patients were randomly entered into the
study. Thirty had three trial treatments with manual stimulation of needles
(MS), electrical low frequency stimulation at 2 Hz (LF), and high-frequency
stimulation at 80 Hz (HF), and then continued treatment with the mode they
felt most benefited them. Ten patients were put on the waiting list for
treatment but served as the untreated control group. The results were
evaluated after 6 weeks and at 6 months for: activity related to pain;
mobility; verbal descriptors of pain and the patient's subjective
assessment of his condition.
After 6 weeks, patients receiving treatment
showed significant improvement (P < 0.05 to P < 0.001) on three of the four
measures compared to the untreated controls. After 6 months a similar measure of significant improvement was seen in patients continuing with
low-frequency (LF) acupuncture, but not in those groups continuing with
manual stimulation (MS) or high-frequency (HF) acupuncture. The results
suggest that 2 Hz electrical stimulation is the mode of choice when using acupuncture in the treatment of chronic nociceptive low back pain.
