Study on the treatment of dysphagia after stroke with electromyographic biofeedback intensive training

Figure 2 Comparison of the forward and upward movement speed of the hyoid bone. All statistical data in this study were entered into excel software by the first author and the corresponding author respectively, and the statistical processing software was SPSS 25.0 for calculation, expressed as the measurement of mean ± SD. The data that did not conform to the normal distribution were described by M (QR), and the Mann-Whitney test was used. The data that conformed to the normal distribution were found using repeated measures analysis of variance. There was no significant difference between the two groups (P > 0.05). After 4 wk of treatment, it was found that the forward and upward movement speed of the hyoid bone in the three groups was significantly improved compared with the previous one. The difference in movement speed between groups was statistically significant (P < 0.05), among which the forward and upward movement rates of the hyoid bone in the electromyographic biofeedback (EMGBF) group and the enhanced EMGBF group were significantly higher than those in the conventional group, and the forward and upward movement of the hyoid bone in the enhanced EMGBF group was higher than that in the EMGBF group. The rate improved significantly, and the statistics showed that the difference was statistically significant (P < 0.05). A: Forward movement speed of hyoid bone; B: Upward movement speed of hyoid bone. EMGBF: Electromyographic biofeedback.
