Auriculotherapy treatment in fibromyalgia: A randomized trial

Interventions: Participants were randomized to one of three arms: TT group (auriculotherapy true treatment), NST group (needle sham treatment), and VSST group (vaccaria seeds sham treatment). They received their treatment three times at one-month intervals. Outcome Measures: Primary outcome was the Fibromyalgia Impact Questionnaire (FIQ).

Secondary outcomes included pain scores, pain medications, sleep quality, fatigue, anxiety, depression, cognition, physical functional capacity, and global impression of change. All these outcomes measured at early and at late post-treatment evaluations were compared to the preinclusion evaluation. Results: The percentage of patients having an improvement of FIQ were similar between groups (p=0.245); comparison between TT and VSST group patients was also not statistically significant (p=0.232).

FIQ was also similar in the three groups at early post-treatment evaluation considered as absolute values or as variation from inclusion (p=0.910). All secondary outcomes were similar between groups but patients in the TT group presented less pain at the day of visit compared to patients in the VSST group (p=0.018) and global impression of change was statistically different between groups (p=0.029). Comparison between TT and VSST group patients was also different (p=0.012).

One serious adverse event occurred in the TT group. Conclusions: Mixed results lead us to propose qualitative studies in addition to quantitative studies to assess the effectiveness of a specific auriculotherapy treatment.
