Abstract
Background:Cerebral palsy (CP) refers to a collection of permanent mobility and postural impairments that are caused by non-progressive disruptions in the fetal or infant brain throughout development. Children with cerebral palsy have motor abnormalities that are commonly accompanied by sensory and cognition disorders as well as seizures and secondary musculoskeletal difficulties.Purpose:To check if there were any correlations between the ultrasonography pictures of muscle thickness and muscle pennation and the muscle strength in hemiplegic cerebral palsied children.Materials and methods:Only one group contained thirty children from both sexes diagnosed as CP in the form of spastic hemiplegia. Their age ranged from two to six years. They were recruited with a consent form signed by their parents and selected according to modified Ashworth scale as grade 1 and 1+ spasticity. Ultrasonography was used to measure the muscle architecture parameters while dynamometer was used to measure muscle strength.Results:There was a mild positive correlation between biceps brachii strength and muscle thickness (r = 0.46, p = 0.01), and a mild positive correlation between biceps brachii strength and angle of pennation (r = 0.37, p = 0.03) on the affected side. While the non-affected side, there was a moderate positive correlation between biceps brachii strength and muscle thickness (r = 0.51, p= 0.004), and a mild positive correlation between biceps brachii strength and angle of pennation (r = 0.39, p = 0.03).Conclusion:There is a significant correlation between biceps brachii strength and both; muscle thickness and pennation angle of the biceps brachii muscle in the affected and non-affected sides of the spastic hemiplegic cerebral palsy children.
