Acupuncture in the treatment of posttraumatic pain syndrome.

To test the hypothesis that classical Chinese acupuncture provides an additional benefit subjectively as well as objectively in patients suffering from reflex sympathetic dystrophy, a double-blind, placebo-controlled prospective trial was performed. Fourteen patients suffering clinically and scintigraphically from acute CRPS of the upper limb lasting of more than one but less than 6 months were studied. Patients were randomly assigned to either the classical acupuncture (group A) or sham acupuncture (group S), which was applied five times a week for three weeks and required 30 minutes. Both groups received the same defined standard treatment. The current state of pain was assessed by means of a visual analogue scale. Subjective success of treatment was rated by the patients by means of a rating scale. Each patient underwent a clinical examination and was investigated by 5-phase bone scan in order to confirm the diagnosis. The current state of pain as well as clinical parameters were almost identical in patients of group A and of group S at the beginning. During therapy clinical parameters as well as pain improved in both groups and reached nearly normal levels after 6 months. Owing to the small number of patients in our study, no differences between sham and treatment group could be recognized. For a definitive statement the treatment of further patients in both groups is planned. Determinations of the effect of acupuncture on clinical parameters, based on long-term follow-ups are projected.
