The general movement optimality score: a detailed assessment of general movements during preterm and term age

AIM: To explore the appropriateness of applying a detailed assessment of general movements and characterize the relationship between global and detailed assessment.METHOD: The analysis was based on 783 video recordings of 233 infants (154 males, 79 females) who had been videoed from 27 to 45 weeks postmenstrual age. Apart from assessing the global general movement categories (normal, poor repertoire, cramped-synchronized, or chaotic general movements), we scored the amplitude, speed, spatial range, proximal and distal rotations, onset and offset, tremulous and cramped components of the upper and lower extremities. Applying the optimality concept, the maximum general movement optimality score of 42 indicates the optimal performance.RESULTS: General movement optimality scores (GMOS) differentiated between normal general movements (median 39 [25-75th centile 37-41]), poor repertoire general movements (median 25 [22-29]), and cramped-synchronized general movements (median 12 [10-14]; pINTERPRETATION: Further research might demonstrate that the GMOS provides a solid base for the prediction of improvement versus deterioration within an individual general movement trajectory.
