Objective:To observe any effect of low-frequency whole body resonant stimulation on the ba-lance and walking ability of hemiplegic stroke survivors.Methods:Sixty-six stroke survivors with hemiplegia were randomly divided into a low-frequency resonance training group, a high-frequency vibration training group and a control group, each of 22. All received routine exercise training at individualized intensities. All three groups underwent five 1-minute cycles of 7Hz, 15Hz or 1Hz stimulation twice a day, five days a week for eight weeks. Before and after the intervention, balance and walking ability were evaluated using the Berg Balance Scale, the timed up and go test and a 10m walking test. Step length, step frequency and step speed were also measured.Results:There were no significant differences among the three groups before the training. Afterward, significant improvement was observed in all of the groups in terms of all of the measurements. The average results of the low-frequency resonance training group were at that point significantly better than the other two groups′ averages, while the high-frequency vibration training group′s results were superior to those of the control group.Conclusion:Resonance training at 7Hz is the most effective in improving the balance and walking ability of stroke survivors with hemiplegia.
Résumé
Objective To observe the clinical efficacy of acupoint injection plus nerve electrical stimulation in treating deglutition disorders after cerebral stroke. Method Seventy-seven patients with deglutition disorders after cerebral stroke were randomized into an electrical stimulation group of 24 cases, a hydroacupuncture group of 26 cases, and a comprehensive group of 27 cases, to respectively receive Vitalstim electrical stimulation, acupoint injection of Mecobalamin, and both of the treatments, 5 d as a treatment course, with 2-day interval between two courses, for 4 courses in total. The modified water-drinking test and Standardized Swallowing Assessment (SSA) were adopted to evaluate the therapeutic efficacy before the intervention, after 20-day treatment, and after 60-day treatment, and the therapeutic efficacies were compared. Result The modified water-drinking test and SSA scores were significantly changed in the three groups after 20-day treatment compared with that before the intervention, and the scores in the comprehensive group were superior to that of the electrical stimulation group and hydroacupuncture group. However, on the 60th day, the scores were equivalent among the three groups. Conclusion The Vitalstim electrical stimulation and acupoint injection of Mecobalamin both can produce certain treatment effects for deglutition disorders after cerebral stroke;the two methods can work in a synergistic way and can boost the improvement of swallowing function.
