Background and aim of the study: Every movement is accompanied by postural adjustments. The first level of postural control is direction-specificity, implying that when the body moves forward the dorsal muscles are primarily activated. Children with Cerebral Palsy (CP) have problems with postural control. Little is known about de development of postural control in children with CP. Aim of this study is to evaluate arm muscle activity and postural control during reaching of typically developing infants and infants who are at high risk for CP. Methods: 11 typically developing children and 46 children at high risk for CP were assessed at the age of 4, 6 and 18 months. While the children were reaching to a toy, the activity of arm, neck and trunk muscles was measured with EMG. The children at high risk for CP were randomized into two intervention groups: traditional infant physiotherapy and a new family-centered program named COPCA. The analysis focused on the activity of the prime-mover, i.e. the arm muscle recruited first during reaching, and direction-specificity. Results: Large variation was seen in muscle activity, but within the variation a few differences are noticed: infants who developed CP used the deltoid muscle in 75% of the trials as prime-mover, the other high-risk infants in 44% and the control group in 35% of the trials. At the age of 4 and 6 months the control and high-risk group showed direction-specificity in 55-60% of the trials. At the age of 18 months the control group showed in 88% of the trials direction-specificity, which was significantly more often than the high-risk group did (60%; p=0,002). Development of prime-mover activity and direction-specificity in the two intervention groups was comparable. Conclusion: The infants who developed CP showed more stereotyped use of the prime-mover. Direction-specificity at early age was present in the high-risk group, but at the age of 18 months high risk infants showed a delay in the development of direction-specificity. The effect of COPCA and traditional physiotherapy on prime-mover use and direction-specificity was comparable.
