Object : This study is designed to evaluate the clinical therapy of acupuncture by the data of DITI(Digital Infrared Thermographic Imaging) and FNT(Facial Nerve stimulation Test) examination and the changes of clinical symptoms after the therapy of acupuncture in the patients with Bell's palsy. Contents : The conservative therapy with acupuncture was performed during 1-8weeks. The acupuncture points of S4, S6, G14, S2, BL2, SI18, TE23, LI4 and S36 were used. In the pre- and post therapy, DITI examinations was performed in patients who had Bell's palsy and were treated by acupuncture, and then tried to correlate the results of clinical symptoms with the difference of thermographic findings. And FNT examinations were performed in the same patients above, and then tried to correlate the results of clinical symptoms with the difference of nerve response findings. Setting : The standard routine thermographic examination with thermography (DITI) and nerve response with FNT(Facial Nerve Stimulation Test) were performed in the 16 patients with Bell's palsy at pre- and post acupuncture. Patients : Thermographic imaging of 16cases was analyzed. They had diagnosed Bell's palsy. They were treated by acupuncture and moxibustion therapy in Wonkwang Oriental Hospital from Jauary, 1999 to February, 2000. Results : 1) The results of treatment showes that 56.25% of patients achieved clinical excellent recovery and 31.25% achieved good recovery. After compairing the DITI results before and after treatment, we found 43.75% of patients achieved excellent recovery and 43.75% achieved good recovery. 2) After compairing the FNT results before and after treatment, we found 25% of patients achieved excellent recovery and 56.25% achieved good recovery. Conclusion : 1) Acupuncture showed good results over 87.5% in clinical evaluation and 87.5% in DITI. Thermographic examination showes terapeutic effect of acupuncture treatment. 2) Acupuncture showed good results over 87.5% in clinical evaluation and 81.25% in FNT. FNT showes nerve response recovery effect of acupuncture treatment.
