Observation of efficacy on dysphagia after stroke while strengthen the training of respiratory function

Abstract

Objective To observe the improvment on patients who has dysphagia after stroke after strengthening the training of respiratory function and normal swallowing function. Methods Use Random digital table to devide 60 patients into two groups-control group and treatment group. And all patients used to be treated in the Department of Rehabilitation between June 2014 and June 2016. Ther were 30 cases in each group. The control group were treated with conventional swallowing function training with low frequency electrical stimulation, swallowing training was divided into direct and indirect training. Including exercise training of swallowing organs, thermal stimulation training, swallowing auxiliary techniques and the adjustment of viscosity. On the basis of control group′s training, treatment group strengthen the training of respiratory function, which 2 times a day, once a 10 minutes. Both two groups did the test before the treatment and eight weeks after treatment. We use water swallow test, the standard of assessing degree of stroke neurological impairment on dysphagia subscale Rosenbek aspiration level grading to evaluate the efficacy. Results Before treatment, these two groups barely had difference on water swallow test, the standard of assessing degree of stroke neurological impairment on dysphagia subscale, Rosenbek aspiration level grading(P>0.05), while after 8 week′s treatment, patients in treatment group improved a lot on water swallow test, the standard of assessing degree of stroke neurological impairment on dysphagia subscale, Rosenbek aspiration level grading(P<0.05). Treatment group′s scores were [( 2.03±0.68), (8.52±1.66) and (2.55±1.12)] compared with the control group [(2.55±0.91), (7.21±2.29) and (3.55±1.82)]. It has significantly improvement and has statistically significant (P<0.05) Conclusion Strengthening the training of respiratory function and normal swallowing function both can effectively improve the swallowing function in patients with stroke, and if increase training in respiratory function gonna be better.
