| Objective: To explore the effect of phrenic nerve electrical stimulation on respiratory function, and to study the curative effect of phrenic nerve electrical stimulation combined with articulation training on patients with dysarthria after stroke. Methods: A total of 70 patients with dysarthria after stroke were randomly divided into observation group and control group, 35 cases in each group. The observation group was treated with phrenic nerve electrical stimulation combined with dysarthria training, while the control group was treated with phrenic nerve pseudo-stimulation combined with dysarthria training. The treatment period was 3 weeks. Before and after treatment, the modified French Day Dysarthria Assessment Scale (m-FDA), the longest sound time (MPT), the maximum inspiratory pressure (MIP) and the peak expiratory flow rate (PEF) were used. Results: After treatment, m-FDA, MPT, MIP and PEF in the observation group and the control group were significantly higher than those before treatment (P<0.05). After treatment, the scores and total scores of m-FDA in the observation group were significantly higher than those in the control group (P<0.05), and MPT, PEF and MIP were also significantly higher than those in the control group (P<0.05). Conclusion: Compared with simple articulation training, combined use of phrenic nerve electrical stimulation and articulation training can significantly improve articulation disorder after stroke. |
