Insights
Fidgety general movements (GMA) in infants are the most accurate predictors of later cerebral palsy (CP). However, all spontaneous movement assessments have a high rate of false positives, requiring careful interpretation.
Area of Science:
- Neurology
- Developmental Pediatrics
- Movement Science
Background:
- Early detection of cerebral palsy (CP) is crucial for timely intervention.
- Spontaneous infant movements are potential early biomarkers for neurodevelopmental disorders.
- The predictive accuracy of various infant movement assessments for CP requires systematic evaluation.
Purpose of the Study:
- To systematically review the predictive validity of spontaneous early infant movements for the later development of cerebral palsy (CP).
- To compare the diagnostic accuracy of different methods for assessing general movements in infancy.
Main Methods:
- A systematic review of cohort studies was conducted, searching four major electronic databases (CINAHL, Embase, MEDLINE, PsycINFO).
- Studies reporting on the predictive validity of early spontaneous movements for later CP were included.
- Data from 47 studies were analyzed to calculate sensitivity and specificity for various movement assessments.
Main Results:
- The Prechtl General Movements Assessment (GMA) during the fidgety period (10-20 weeks corrected age) demonstrated the highest predictive validity for CP (sensitivity: 97%, specificity: 89%).
- The Prechtl GMA during the writhing period (0-6 weeks) showed lower specificity (59%) compared to the fidgety period.
- Cramped-synchronized movements had high specificity (97%) but moderate sensitivity (70%), while Hadders-Algra's method showed good pooled sensitivity (89%) and specificity (81%).
- Assessments like the Hammersmith Infant Neurological Examination showed weak associations with later CP.
Conclusions:
- Fidgety general movements, as assessed by the Prechtl GMA, are the most potent predictors of later cerebral palsy.
- Despite high predictive value, the presence of false positives across all spontaneous movement assessments necessitates cautious interpretation.
- No single spontaneous movement assessment can be used in isolation for definitive CP diagnosis.
Aim:
To systematically review the predictive validity of spontaneous early infant movements for later cerebral palsy (CP).
Method:
Cohort studies with published data to calculate predictive validity of early spontaneous movements for later CP were searched in four electronic databases: CINAHL, Embase, MEDLINE, and PsycINFO.
Results:
Forty-seven studies met inclusion criteria. The Prechtl General Movements Assessment (GMA) during the fidgety period (10-20wks corrected age) had the strongest sensitivity: 97 per cent (95% confidence interval [CI] 93-99) and specificity: 89% (95% CI 83-93). The sensitivity and specificity of the Prechtl GMA during the writhing period (birth-6wks) was 93% (95% CI 86-96) and 59% (95% CI 45-71) respectively. Cramped-synchronized movements in the writhing period according to Prechtl had the best specificity (sensitivity: 70% [95% CI 54-82]; specificity: 97% [95% CI 74-100]). Hadders-Algra's method of assessing general movements had a pooled sensitivity and specificity of 89% (95% CI 66-97) and 81% (95% CI 64-91) respectively. Presence of asymmetric postures and movement quality/quantity were reported under the Hammersmith Infant Neurological Examination, Hammersmith Neonatal Neurological Examination, and Movement Assessment of Infants but had weak associations with later CP.
Interpretation:
Fidgety movements assessed by the Prechtl GMA have the strongest predictive validity for later CP, but cannot be considered in isolation because of the presence of false positive results.
What This Paper Adds:
Fidgety general movements (Prechtl) are most predictive for later cerebral palsy compared with other spontaneous movements. False positive results are high among all spontaneous movement assessments.
