Comparison of Treatment Effects between Electro-Acupuncture and in Situ Acupuncture in Patients with Intractable Hunt Syndrome / 日本東洋医学雑誌

ABSTRACT

We retrospectively compared the treatment effects of electro-acupuncture against <i>in situ</i> acupuncture, in 15 Hunt's Syndrome patients who underwent acupuncture therapy in our institution between August 1996, and June 2004, and who had fulfilled 3 electroneurography (ENoG) criteria with a value of 0% within 90 days after onset, had a paralysis score of <20, and could be followed up for 6 months after onset. Electroacupuncture therapy was performed on the paralysis side of the faces of 8 patients (the electro-acupuncture group), while <i>in situ</i> acupuncture therapy was performed on the remaining 7 (the <i>in situ</i> acupuncture group). No significant differences were observed in the background factors between the two groups. Treatment results were evaluated using the 40-point paralysis score described by Yanagihara, as well as a sequela score, which was a modified method of the sequela assessment developed by Nishimoto and Murata et al. Changes in paralysis scores from first acupuncture therapy, out to 6 months post-onset were compared using repeated ANOVA measures, and Mann-Whitney U tests respectively. Recovery of paralysis scores did not significantly differ between the two groups (p=0.0507), although slightly better recovery was observed in the electroacupuncture group, as compared with the <i>in situ</i> acupuncture group. Additionally, sequelae scores did not significantly differ between the two groups (p=0.51). In recent years, many have been of the opinion that lowfrequency stimulation is contraindicated. In this study, however, the incidence of sequelae did not differ significantly between the electro-acupuncture therapy and the <i>in situ</i> acupuncture therapy groups, although slightly better paralysis recovery was observed in the former.
