[Electromyographic study of movements in infants with cerebral palsy (author's transl)].
In 43 infants between 3 and 16 months old electromyographic studies were performed by recording movement patterns. Surface electrodes were fixed to the legs, recording the activities of adductors, small gluteal muscles, M. rectus and hamstrings. The impulses were fed into the computer. Synergistic and antagonistic muscles were compared by correlation analysis. Certain movement patterns were provoked by turning the infants from supine to the sides, pulling up to sitting, tilting sideways, vertical hanging and standing. Synergistic and antagonistic muscle groups were compared by correlation anaysis. Significant differences in motor behavior were shown to exist between spastic and healthy infants: The spastic infants showed widely spread synchronous innervations. Besides, comparison of mean activity values exposed a significant preponderance of mean activity values exposed a significant preponderance of adductor activity to gluteal activity in spastic infants. - In qualitative analysis by a rating system diagnostic differentiation of individual cases was possible. This proved of special value in infants with postural asymmetries or abnormal musculatur tone.
