Insights
Home filming for General Movement Assessment (GMA) is effective for early cerebral palsy detection. Parents found home filming easy and effective, supporting remote GMA implementation in high-risk infant follow-up.
Area of Science:
- Neuroscience
- Developmental Pediatrics
- Medical Technology
Background:
- General Movement Assessment (GMA) is crucial for early cerebral palsy (CP) risk detection but requires expert clinicians.
- Implementing remote GMA via home filming can overcome accessibility barriers.
Purpose of the Study:
- To implement and evaluate home- and hospital-based filming for remote GMA in Norwegian high-risk infants.
- To assess parental experiences and concerns regarding home filming.
Main Methods:
- Prospective cohort study involving infants referred for neurodevelopmental follow-up.
- Parents collected two home videos and one hospital video using the In-Motion App.
- Videos were assessed remotely by GMA experts using Prechtl's GMA standards.
Main Results:
- 102 infants participated; 96.8% of families submitted home videos (177 total).
- All home videos (177) were GMA scorable; only 3.1% of hospital videos (95) were not scorable.
- 91.7% of parents found home filming easy; 79.5% agreed videos can be taken at home instead of hospital.
Conclusions:
- Home filming by parents and remote GMA effectively support early CP detection in high-risk programs.
- Remote GMA implementation can facilitate timely intervention, improving functional outcomes for children with CP.
Background:
General Movement Assessment (GMA) is recommended for early detection of risk for cerebral palsy but requires trained clinical experts. We aimed to implement home- and hospital-based filming for remote GMA in a Norwegian high-risk infant cohort, as well as evaluating parents' experiences in filming their infant at home.
Methods:
This knowledge translational study used a prospective cohort design including participants referred to neurodevelopmental follow-up across three sites in the Central Norway Regional Health Authority. Two home films of the fidgety type of general movements were collected between 12+1-14+6 and 15+1-17+6 weeks after term by parents. An additional film was collected at the hospital between 12+1 and 17+6 weeks after term. The instructional guide for all filming was the In-Motion App standards. Videos were transferred to a remote GMA team and classified as either "GMA scorable" or "GMA not scorable" based on Prechtl's GMA standards. Parents responded to an online survey using a 5-point Likert scale to collect information about their perspectives, experiences, and possible worries by filming their infant at home.
Results:
One-hundred-and-two infants from 95 families participated. Ninety-two (96.8%) families transferred 177 home-based videos. Eighty-four (92%) of these had 95 videos taken in their local hospital. All 177 home-videos were "GMA scorable" and three (3,1%) out of 95 hospital-based videos were classified as "GMA not scorable". Eight families did not respond to the survey and two families did not receive the survey due to a technical error. Seventy-eight (91.7%) respondents agreed or strongly agreed that it was easy to perform home filming and five (5.9%) agreed that they were more worried about their child`s development after filming at home. Almost 80% of respondents agreed that a video for GMA can be taken at home instead of in hospital.
Conclusions:
This study strengthens the clinical implementation of home filming by parents and remote GMA for early detection of CP in high-risk follow-up programs. The implementation of remote GMA has the potential to facilitate early intervention to improve function in children with CP in line with international recommendations.
