Insights
Surface electromyography (sEMG) effectively diagnoses pediatric dysphagia. sEMG values correlate with dysphagia severity and improve after treatment, aiding therapeutic evaluation.
Area of Science:
- Pediatric Medicine
- Neurology
- Rehabilitation Science
Background:
- Pediatric dysphagia presents significant challenges in diagnosis and management.
- Objective assessment of swallowing function is crucial for effective intervention.
Purpose of the Study:
- To evaluate the diagnostic and therapeutic efficacy of surface electromyography (sEMG) in children with dysphagia.
Main Methods:
- Compared sEMG integral values of submental and infrahyoid muscles in 20 children with dysphagia and 20 healthy controls.
- Measured resting and post-swallowing (5 mL water) muscle activity.
- Assessed changes in sEMG values after 1 month of rehabilitation and correlated values with dysphagia severity.
Main Results:
- No significant difference in resting sEMG values between groups.
- Significantly higher post-swallowing sEMG values in the dysphagia group compared to controls (P<0.05).
- sEMG values significantly decreased post-treatment (P<0.05), correlating positively with dysphagia severity (P<0.01).
Conclusions:
- sEMG is a valuable tool for diagnosing pediatric dysphagia.
- sEMG effectively monitors treatment response and therapeutic outcomes in children with dysphagia.
Objective:
To study the application value of surface electromyography in children with dysphagia.
Methods:
A total of 20 children with dysphagia were enrolled as the observation group, and 20 healthy children, matched for sex and age, were enrolled as the control group. Surface electromyography was used to record the electromyography integral values of the submental and infrahyoid muscle groups in the resting state and the state after water swallowing. The two groups were compared in terms of the electromyography integral values of the submental and infrahyoid muscle groups in the resting state and the state after swallowing 5 mL water. The observation group was observed in terms of the changes in the electromyography integral values of the submental and infrahyoid muscle groups after 1 month of rehabilitation treatment. A Spearman correlation analysis was used to evaluate the correlation of the degree of dysphagia with the electromyography integral values of the submental and infrahyoid muscle groups in the observation group.
Results:
There was no significant difference between the two groups in the electromyography integral values of the submental and infrahyoid muscle groups in the resting state (P>0.05), while after water swallowing, the observation group had significantly higher electromyography integral values than the control group (P<0.05). The observation group had significant improvements in the clinical symptoms of dysphagia after treatment, with significant reductions in the electromyography integral values of the submental and infrahyoid muscle groups (P<0.05). The severity of dysphagia was positively correlated with the electromyography integral values of the submental and infrahyoid muscle groups (P<0.01).
Conclusions:
Surface electromyography is useful in the diagnosis and therapeutic effect evaluation for dysphagia in children.
