Comparison of the Onset Times of Antigravity Flexor Muscle Activity During Head Lift in Supine Position between Children with Cerebral Palsy and Healthy Children

The purpose of this study was to compare the muscle onset time of sternocleidomastoid (SCM) and rectus abdominalis (RA) muscle activity during head lift in supine position between cerebral palsy and healthy children. Ten cerebral palsy children and 10 age, sex-matched healthy children were recruited for this study. Muscle activity of the SCM and RA were collected by surface electromyography (MP100SWS). Results demonstrated that the muscle onset time order was not significantly different between cerebral palsy children and healthy children. However, the DMHT and ST between SCM and RA during head lift in supine position were significantly shorter in healthy children than in cerebral palsy children. Further studies are needed to clarify the mechanism of differences in muscle activation patterns during head lift in supine position in cerebral palsy children compared with healthy children.
