“…All infants had participated in two previous studies on the GMA. 12,18 Infants were considered to be at high risk of CP development if they had a gestational age lower than 28 weeks and ⁄ or a birthweight below 1000g, or had specific risk factors as described elsewhere 12 (see Table I). In addition, to be included, at least one video recording of the infant during the fidgety period with general movement analysis had to be available.…”

AIM The aim of this study was to investigate the predictive value of a computer-based video analysis of the development of cerebral palsy (CP) in young infants.METHOD A prospective study of general movements used recordings from 30 high-risk infants (13 males, 17 females; mean gestational age 31wks, SD 6wks; range 23-42wks) between 10 and 15 weeks post term when fidgety movements should be present. Recordings were analysed using computer vision software. Movement variables, derived from differences between subsequent video frames, were used for quantitative analyses. CP status was reported at 5 years.RESULTS Thirteen infants developed CP (eight hemiparetic, four quadriparetic, one dyskinetic; seven ambulatory, three non-ambulatory, and three unknown function), of whom one had fidgety movements. Variability of the centroid of motion had a sensitivity of 85% and a specificity of 71% in identifying CP. By combining this with variables reflecting the amount of motion, specificity increased to 88%. Nine out of 10 children with CP, and for whom information about functional level was available, were correctly predicted with regard to ambulatory and non-ambulatory function.INTERPRETATION Prediction of CP can be provided by computer-based video analysis in young infants. The method may serve as an objective and feasible tool for early prediction of CP in highrisk infants.Cerebral palsy (CP) is a permanent disorder in the development of movement and posture in the developing fetal or infant brain 1 and is one of the major disabilities that result from extremely preterm birth. [2][3][4] The utility of predictive assessment tools in young infants is limited by the need for expensive equipment and highly experienced personnel, as well as low accuracy. Although the primary insult(s) cannot be repaired, early identification of CP enables intervention to be instituted while the plasticity of the nervous system is high. [5][6][7][8] Early identification may also lead to more focused follow-up and reassure the parents of those children who are unlikely to develop CP.In young infants, neurological damage is typically expressed by means of generalized and non-specific dysfunction. 9 The General Movement Assessment (GMA), based on systematic observation of infants' spontaneous movements from video recordings, has been shown to predict CP with high accuracy. 10,11 The absence of fidgety movements at 2 to 4 months corrected age may identify infants who will develop CP with more than 90% sensitivity. 10,[12][13][14] Although the GMA has been demonstrated to predict CP with high accuracy, it depends on highly experienced observers, and its use in clinical practice is limited. 12,15,16 A software program developed within the Max/MSP/Jitter environment for analysing music-related movements in musicians and dancers 17 has recently been customized for the purpose of studying fidgety movements.

Objective: To review the literature regarding screening psychomotor tests for the early identification of developmental problems. Sources:A search on SciELO, PubMed and Google Scholar was performed using the terms "prematurity," "developmental delay," "cerebral palsy," "early diagnosis" and "evaluation tests." Summary of the findings:A total of 455 references were listed, and 174 studies were selected for this review based on title, relevance, and abstract. Only original and electronically available material, from 1985 forward, with information on design, applicability, and psychometric properties of those tests was included. Conclusions:Screening tests are important to speed the beginning of treatment measures in order to allow for better developmental outcome. Among the many tests that can be employed for this purpose, the DENVER II and the Alberta Infant Motor Scale are the most often used in Brazilian studies. The Movement Assessment of Infants is starting to be used in our country. Two other tests are recommended in the literature due to their high sensibility and specificity:the Test of Infant Motor Performance and the General Movements.J Pediatr (Rio J). 2008;84(4):289-299: Prematurity, motor delay, early diagnostic, screening tests.

The challenge of identifying infants who are at risk for developmental delay and possible adverse neurodevelopmental outcome demands methods of evaluation that will lead to early intervention to minimize developmental disability and to maximize the infant's potential. A qualitative assessment of spontaneous general movements (GMs) in the preterm, term, and young infant at risk is a valid and reliable tool for evaluation (Prechtl [1990] Early Hum. Dev. 23:151-158). The aim of this review is to describe the theoretical and clinical bases for the assessment of GMs and its relationship to developmental delay and brain dysfunction. Thirty-seven studies related to the predictive validity of GMs were included in this review. Results suggested that consistent cramped synchronized GMs are highly predictive of later development of cerebral palsy. The fidgety movement quality that appears at the age of 2 to 3 months was found to be a most sensitive predictor of neurodevelopmental outcome in different populations of infants.
