Insights
Video assessments of general movement assessment (GMA) are reliable for identifying infants at risk of neurological dysfunction. This method proved feasible in a busy Danish pediatric clinic, showing high inter- and intra-observer agreement.
Area of Science:
- Pediatric neurology
- Developmental pediatrics
- Clinical assessment methods
Background:
- General movement assessment (GMA) is crucial for early detection of neurological impairments like cerebral palsy.
- Certified training in GMA is available, but its application in real-world clinical settings needs validation.
- Assessing GMA via video recordings offers a potential solution for busy outpatient clinics.
Purpose of the Study:
- To evaluate the feasibility and reliability of using video recordings for General Movement Assessment (GMA) in a Danish pediatric outpatient clinic.
- To determine the inter-observer and intra-observer reliability of video-based GMA.
Main Methods:
- 30 infants born with perinatal asphyxia were video recorded at three months of age.
- Two certified GMA observers assessed the video recordings.
- Assessments were repeated two weeks later to evaluate intra-observer reliability.
- Inter- and intra-observer agreements were analyzed using proportional agreement and nominal kappa statistics.
Main Results:
- Substantial to almost perfect inter- and intra-observer reliability was observed.
- Intra-observer agreement ranged from 0.85 (95% CI: 0.65-1.00) to 0.85 (95% CI: 0.62-1.00).
- Inter-observer agreement was 0.71 (95% CI: 0.45-0.96) initially and 0.85 (95% CI: 0.63-1.00) two weeks later.
- All video recordings were completed promptly within the clinic setting.
Conclusions:
- Video-based General Movement Assessment is a reliable method in a busy pediatric outpatient setting.
- Formal training and regular use of GMA are key to achieving high reliability.
- This approach supports early identification of neurological dysfunction in infants.
Aim:
General movement assessment (GMA) can help to identify children with a high risk of developing neurological dysfunction, such as cerebral palsy, and certified training is provided in this specialism. The aim of this study was to investigate the feasibility and reliability of using video recordings to assess GMA, in a busy Danish outpatient clinic.
Methods:
The study comprised 30-term infants born with perinatal asphyxia, who were video recorded at three months. They were assessed by two certified GMA observers and re-assessed two weeks later. Interobserver and intra-observer agreements were analysed using proportional agreement, and nominal kappa statistics were used to calculate 95% confidence intervals (95% CI).
Results:
We found substantial and almost perfect interobserver and intra-observer reliability. Intra-observer agreement was 0.85 (95% CI: 0.65-1.00; p < 0.0001) and 0.85 (95% CI: 0.62-1.00; p < 0.0001), and interobserver agreement was 0.71 (95% CI: 0.45-0.96; p < 0.0001) at time point one and 0.85 (95% CI: 0.63-1.00; p < 0.0001) two weeks later. All video recordings were completed within our multidisciplinary outpatient clinic without delay.
Conclusion:
This study demonstrated the reliability of the GMA method in a busy multidisciplinary Danish paediatric outpatient setting, when assessors had been formally trained in the method and used it regularly.
