Correlation between age, muscle architecture, and muscle strength in children with Erb’s palsy

Abstract

Background Muscle weakness is a widespread problem in children with Erb’s palsy as it can cause changes in muscle architecture parameters, which can be detected by ultrasonography. This study was conducted to determine the relation between age, muscle architecture, and muscle strength in children with Erb’s palsy. A total of 40 children with Erb’s palsy from both sexes aged 1–2.5 years were included in this study. Muscle thickness and pennation angle were measured by ultrasonography, and muscle strength was measured using the active movement scale. Results A significant relation was found between age, muscle thickness, pennation angle, and muscle strength (P < 0.05). Moreover, a significant difference was found in muscle architecture parameters during relaxation and contraction in both study groups and in each study group (P < 0.05). Conclusion Muscle weakness in children with Erb’s palsy has an effect on muscle architecture parameters, and these parameters also increase with age.

Comparison of the efficacy of two interventions in ameliorating abdominal thickness and sitting function in children with diplegia

“…The researcher finally calculated the score by dividing the number of achieved tasks by the total number of sitting domain tasks and multiplying by 100 to obtain the achieved task percentage, which was recorded and saved. 30 …”
