ABSTRACT
Objective: To observe the effect of acupoint massage plus Vitalstim electrical stimulation on deglutition function and surface electromyography (SEMG) of deglutition muscle groups. Methods: A total of 60 patients with deglutition disorder after stroke were selected and divided into an electrical stimulation group, a massage group and an integrated group according to the random number table method, with 20 cases in each group. Patients in these three groups were given the same routine rehabilitation training for deglutition. In addition, patients in the electrical stimulation group were given extra Vitalstim electrical stimulation, patients in the massage group were given extra acupoint massage on the head, face and neck, and patients in the integrated group were given extra acupoint massage plus Vitalstim electrical stimulation. Fujishima Ichiro food intake level scale (FILS) was scored before and after treatment. The swallowing duration and maximal amplitude of masseter muscle in SEMG were evaluated before and after treatment. Results: After treatment, the FILS score and the maximal amplitude of recruitment potential generated by muscular contraction of masseter muscle group in the three groups were higher than those before treatment (all P<0.05), and the swallowing duration of masseter muscle group was shortened compared with that in the same group before treatment (all P<0.05). After treatment, the FILS score in the integrated group was higher than that in the electrical stimulation group and the massage group (both P<0.05). The swallowing duration of masseter muscle group measured by SEMG was lower than that in the electrical stimulation group and the massage group (both P<0.05), while the maximal amplitude was higher than that of the electrical stimulation group and the massage group (P<0.05). After treatment, there were no significant differences in the FILS score, swallowing duration and maximal amplitude of masseter muscle group between the electrical stimulation group and the massage group (all P>0.05). Conclusion: Both acupoint massage and electrical stimulation can improve the deglutition function in patients with deglutition disorder after stroke, and improve the coordination and flexibility of masseter muscle. The integration of the two is more effective.
