46 cases of peripheral facial paralysis were treated by ear and body acupuncture, the effectiveness of which was evaluated clinically and electromyographically.
Method of acupuncture: Mouth, Cheek and Liver points were selected in ear acupuncture group; Hegu, Dicang, Jiache and Zanzhu points in body acupuncture group. 3-4 points homolateral to the paralysed side were used simultaneously in both groups. In majority of these cases manual needling was performed and in some cases electric stimulation was used in addition. Needles were retained in situ for 30 minutes each time, a trial of acupuncture was given every other day. Every course of treatment consisted of 7 trials of acupuncture.
The effectiveness was evaluated following 2-3 courses of treatment during which no other treatment was given.
The EMG activity of the paralysed orbicularis oculi muscle under resting condition and during moderate and strong voluntary contraction as well as the evoked EMG response to electrical stimulation of facial nerve were recorded before and after acupuncture treatment. In a number of cases the immediate effect of ear acupuncture on EMG activity was observed instantly before and after needling.
Analysis of therapeutic effect: in total 21 cases of the ear acupuncture group, 12 were completely cured (57%); 6 evidently effective (29%); 2 improved (9%) and 1 noneffective (5%) thus yielding a rate of effectiveness of 95%. In 25 cases treated by body acupuncture, 18 cases were cured (72%); 3 evidently effective (12%); 2 improved (8%); 2 ineffective (8%), with a rate of effectiveness of 92%. The variation between these two groups is not significant statistically.
In EMG study majority of the patients presented partial and entire denervation of the facial muscle which were much improved following acupuncture treatment, indicating that the paralysed muscle was reinnervated and the normal function of facial muscles was restored after acupuncture treatment. The immediate effect of ear acupuncture shown by an increasing in frequency and an augmentation of the amplitude of muscle potential during strong voluntary contraction was confirmed, presenting an evidence of showing the facilitating action of acupuncture on facial nerve activity.
It is conceivable that, besides the clinical assessment of the disease, an electromyographical follow-up examination of facial paralysis under acupuncture treatment may afford us a more convincing and objective evidence not only for evaluating the therapeutic effect of acupuncture, but also for better understanding of the prognosis of the disease.
