Swallowing Function In Stroke Patients Research Articles

Effect of effortful swallowing training on tongue strength and oropharyngeal swallowing function in stroke patients with dysphagia: a double-blind, randomized controlled trial.

Effortful swallowing training (EST) is a remedial method for the training of swallowing-related muscles in the oropharyngeal phase. However, clinical evidence of its effectiveness is insufficient. To investigate the effects of EST on tongue strength and swallowing function in patients with stroke. Stroke patients with dysphagia were randomly assigned to one of two groups: an experimental group (n = 12) and a control group (n = 12). The experimental group underwent EST, while the control group performed saliva swallowing. Training was conducted 5 days per week for 4 weeks. Both groups underwent conventional dysphagia treatment for 30 min/day, 5 days/week for 4 weeks. Tongue strength was assessed using the Iowa Oral Performance Instrument. The Videofluoroscopic Dysphagia Scale (VDS), based on a videofluoroscopic swallowing study, was used to analyze oropharyngeal swallowing function. The experimental group showed greater improvements in anterior and posterior tongue strength compared with the control group (p = 0.046 and 0.042, respectively), and greater improvement in the oral phases of the VDS (p = 0.017). We recommend EST as a remedial strategy for improving tongue strength and oral swallowing function in patients with stroke.

Application of Cluster Nursing Among Post-Stroke Patients with Dysphagia

Objective: To explore the effect of cluster nursing care among post-stroke patients. Methods: Post-stroke patients with dysphagia (n=72) were randomly divided into two groups: experimental (or intervention) (n=36) the control (n=36). Patients in the experimental group were given cluster care, including swallowing assessment, safe eating guide, swallowing rehabilitation, the establishment of cluster prevention strategy and health education to patients and caregivers. Patients in the control group were given conventional nursing care, and the score of swallowing function, the prevalence of aspiration pneumonia and nursing care satisfactory level in both groups were assessed before and after the intervention. Results: The swallowing function of patients in the two groups were improved after intervention, but patients in the experimental group showed significantly higher improvement than the control group (P<0.05). The incidence of aspiration pneumonia was significantly lower in the experimental group compared to the control group (P<0.05). Moreover, the satisfactory level of nursing management was higher in the experimental group than the control group (P<0.05). Conclusion: Cluster nursing (CN) practice has significantly improved the swallowing function of stroke patients with dysphagia, reduced the incidence of aspiration pneumonia and enhanced the satisfaction of nursing care.

Application effect of swallowing training and ice stimulation combined with electromyography biofeedback therapy in stroke patients with swallowing and coughing

Objective To investigate the application effect of swallowing training and ice stimulation combined with electromyography biofeedback therapy in stroke patients with swallowing and coughing. Methods Seventy-nine stroke swallowing and coughing patients treated were collected and were randomly divided into two groups (39 cases in control group, 40 cases in observation group) according to the digital table.The control group was treated with normal swallowing training, while the observation group was treated with ice stimulation combined with electromyography biofeedback therapy.The clinical intervention effect and the VFSS results before and after the intervention were observed and compared.The complications of the two groups were statistically analyzed. Results The total effective rate of the observation group [90.00%(36/40)] was higher than that of the control group[71.79%(28/39), χ2=4.255, P=0.039]. After eight-week intervention, the VFSS score of the observation group was higher than that of the control group(t=12.173, P=0.000); and the incidence rate of complications of the observation group[7.50%(3/40)] was lower than that of the control group [25.64%(10/39), χ2=4.727, P=0.030]. Conclusion Swallowing training and ice stimulation combined with electromyography biofeedback therapy can significantly improve the swallowing function of stroke patients with swallowing and coughing, and it is safe.

Effects of intermittence oro-esophageal tube feeding on the comfort and swallowing function of paralytic patients with dysphagia

Objective To explore the effect of intermittence oro-esophageal tube feeding on the comfort and swallowing function of paralytic patients with swallowing disorder. Methods A total of 80 paralytic patients with dysphagia who were hospitalized in Neurology Department of the First Affiliated Hospital of Zhengzhou University from January to December 2016 and met the inclusion criteria were selected by convenience sampling method and divided into observation group and control group according to random number table, with 40 cases in each group. Intermittence oro-esophageal tube feeding was used in observation group, and nasogastric feeding was used in control group. The nasopharyngeal comfort of both groups on the third and tenth day of intervention and patients' swallowing function before feeding and on the tenth day of intervention were compared respectively. Results On the third and tenth day of intervention, the differences between the two groups on the symptoms of nasal discomfort, throat pain, oropharyngeal dryness and swallowing discomfort were statistically significant (P 0.05) . Comparing the two groups on the tenth day of intervention, the difference of patients' swallowing function was statistically significant (P<0.01) . Patients' swallowing function recovery on the tenth day of intervention was statistically different between the two groups (P<0.01) . Conclusions Intermittence oro-esophageal tube feeding can significantly improve the comfort and the swallowing function in stroke patients. Thus, intermittence oro-esophageal tube feeding is a worthy method to expand in clinical practice. Key words: Stroke; Deglutition disorders; Intermittence oro-esophageal tube feeding

Effects of bedside self-exercise on oropharyngeal swallowing function in stroke patients with dysphagia: a pilot study.

[Purpose] The purpose of this study was to investigate the effect of self-exercise on oropharyngeal swallowing function in patients with dysphagia. [Subjects and Methods] Nine patients with dysphagia after stroke were recruited. Self-exercise including effortful swallowing, tongue strengthening, and shaker exercise was performed 5 times a week for 4 weeks. Swallowing function was evaluated using the videofluoroscopic dysphagia scale (VDS) based on a videofluoroscopic swallowing study. [Results] There were significant differences in both the oral and pharyngeal phases of the VDS before and after the intervention. [Conclusion] This study demonstrated that bedside self-exercise is a positive method to improve oropharyngeal swallowing function in patients with dysphagia after stroke.

Effects of Tongue-Holding Maneuver Compared with Mendelsohn Maneuver on Swallowing Function in Stroke Patients

Background: Dysphagia is a common complication in stroke patients. This study aimed to investigate the effects of the tongue-holding maneuver over an 8-week period on the swallowing function in stroke patients. Methods: Twenty-eight stroke patients with dysphagia diagnosed within 1 year were randomly allocated to the experimental or control groups. The experimental (n=15) and control groups (n=13) performed the tongue-holding and Mendelsohn maneuver, respectively. And both groups additionally participated in traditional dysphagia therapy. The maneuvers were conducted for thirty minutes a day, five days a week, for six weeks, totaling forty sessions. Swallowing function with the functional dysphagia scale and swallowing pain with the visual analogue scale between the 2 groups were tested by chi-square tests, Mann-whitney testes, and Wilcoxon signed rank tests. Results: The general characteristics, including age, sex, and disease history, between the two groups did not differ. After 8 weeks of intervention, swallowing function at the oral phase and the pharyngeal phase and the total score was significantly improved in both experimental and control groups. Also, swallowing pain decreased significantly in both groups. However, the change to swallowing function and pain between the groups were not different.
