| Outline of Final Research Achievements |
To determine the efficacy of acupuncture for neck/shoulder stiffness, we conducted a randomized, double-blind (practitioner-patient), placebo-controlled study including four arms: treatment with penetrating needles (penetrating treatment), treatment with skin-touch placebo needles (skin-touch placebo treatment), treatment with no-touch placebo needles (no-touch placebo treatment) and control with no treatment (no-treatment control).
Each of penetrating, skin-touch and no-touch placebo treatments has therapeutic effect on neck/shoulder stiffness comparing with no-treatment control, but there was no significant difference in alleviation of stiffness between the three treatments. There was change of blood circulation exclusively in penetrating treatment. The results indicate that acupuncture treatment, whether treatment involving body penetration or not, subjective stiffness would be alleviated, but blood circulation would be improved only when needle is inserted.
