| Abstrakt: | Background: Dysphagia may delay the functional recovery and substantially affects the quality of life after stroke, mainly if left untreated. Electrical stimulation has been reported as a treatment for pharyngeal dysphagia in recent studies, but the therapeutic effect of neuromuscular electrical stimulation (VitalStim) therapy lacks convincing supporting evidence and needs further clinical investigation. Methods: A total of 135 subjects were randomly divided into 3 groups: traditional swallowing therapy (n = 45), VitalStim therapy (n = 45), and VitalStim therapy plus traditional swallowing therapy (n = 45). The traditional swallowing therapy included basic training and direct food intake training. Electrical stimulation was applied by an occupational therapist, using a modifi ed handheld batterypowered electrical stimulator (VitalStim Dual Channel Unit and electrodes, Chattanooga Group, Hixson, Tennessee). The surface electromyography (sEMG), standardized swallowing assessment (SSA), videofl uoroscopic swallowing study (VFSS), and visual analog scale (VAS) were used to assess swallowing function before and 4 weeks after the treatment. Results: A total of 118 subjects with dysphagia completed the study, 40 in the traditional swallowing group and VitalStim therapy group and 38 in the VitalStim and traditional swallowing therapy group. There were signifi cant differences in sEMG values and SSA and VFSS scores in each group after the treatment ( P < .001). After 4-week treatment, sEMG value (917.1; standard deviation [SD], 91.2), SSA value (21.8; SD, 3.5), oral transit time (0.4; SD, 0.1), and pharyngeal transit time (0.8; SD, 0.1) were signifi cantly improved in the VitalStim and traditional swallowing therapy group than in the other 2 groups ( P < .001). Conclusions: Data suggest that VitalStim therapy coupled with traditional swallowing therapy may be benefi cial for poststroke dysphagia. [ABSTRACT FROM AUTHOR] |
