Abstract
|
|
|
Purpose: The purpose of this study was to compare the activities of the abdominal and neck flexor muscles of children with and without cerebral palsy (CP) while lifting the head in a supine position.
Methods: The subjects were eight children with CP and eight children without the disease. The activities of the external
abdominal oblique (EO), internal abdominal oblique (IO), rectus abdominis (RA), sternocleidomastoid (SCM), and RA/SCM muscles were collected by surface electromyography (EMG) when the children lifted their heads. A Mann-Whitney U test was used to compare the activity of each muscle during the head-lifting exercise. Statistical significance was accepted at p<0.05.
Results: The activities of the EO, IO, and RA, and RA/SCM muscles differed significantly between the children with and without CP, but there was no significant between-group difference in the activity of the SCM muscle.
Conclusion: These findings suggest that the abdominal muscles are not employed as much in the activities of children with CP compared to those without the disease. Additionally, those with CP were more dependent on the neck flexor muscle during the head-lifting exercise in a supine position.
