This study investigated whether the potential anxiety relief provided by auricular acupressure could improve the efficacy of habit reversal treatment, as evidenced by improved stomatological and other outcomes ⁽¹⁾. In a pragmatic, randomized, crossover, pilot clinical trial, 83 nail biters (8-12 years old) received habit reversal treatment in combination with either auricular acupressure intended to reduce anxiety (Method A) or placebo auricular acupressure (Method B). The alternative protocol was employed after a two-month washout period. The results showed that forty-one children successfully completed both arms of the treatments and attended all appointments. There were significant differences in the efficacy of habit reversal treatment, the anxiety score, the nail status, and the SGI in favor of Method A. The authors conclude that auricular acupressure appears to improve the efficacy of habit reversal treatment, likely by reducing anxiety.
