Perfect Number of Needles?



Perfect Number of Needles?
Acupuncture has been successfully used in myofascial pain syndromes. However, the number of needles used, i.e. the "dose" of acupuncture stimulation, to obtain the best antinociceptive efficacy, is still a matter of debate. The question was addressed comparing the clinical efficacy of 3 different therapeutic schemes, mainly characterized by different numbers of needles used on 90 patients affected by a painful cervical myofascial syndrome. Patients were divided into 3 groups; the first group of 30 patients was treated with 11 needles, the second group of 30 patients was treated with 5 needles and the third group of 30 patients was treated with 3 needles. Each group underwent eight cycles of somatic acupuncture. In each session and in each group, all needles were stimulated until the pain tolerance threshold was reached; "pain tolerance is the amount of pain a person can handle without breaking down, either physically or emotionally". Pain intensity was evaluated before therapy, immediately after, and at 1 and 3 months follow-up by means of both the Mc Gill Pain Questionnaire and the Visual Analogue Scale (VAS). Pain and the repercussion of pain on the patient's quality of life (DOPE- Descriptors Of Pain Effects) were also measured using a test we developed, administered at each session. In all groups, needles were inserted superficially, except for the two most painful trigger points that were deeply inserted. All groups, independently from the number of needles used, obtained a good and significant therapeutic effect without clinically relevant differences among groups. For this pathology and patients of this kind, the number of needles, 3 or 5 or 11, seems not to be an important variable in determining the therapeutic effect.
