I have for several years been collaborating with researchers at NTNU in Trondheim on developing video analysis tools for studying the movement patterns of infants. This has resulted in several papers, international testing (and a TV documentary). Now there is a new paper out, with some very successful data testing the reliability of the video analysis method:
Valle, Susanne Collier, Ragnhild Støen, Rannei Sæther, Alexander Refsum Jensenius, and Lars Adde.
Test–retest Reliability of Computer-Based Video Analysis of General Movements in Healthy Term-Born Infants.
Early Human Development 91, no. 10 (October 2015): 555–58. doi:10.1016/j.earlhumdev.2015.07.001.
- Test–retest reliability of computer-based video analysis of general movements.
- Results showed high reliability in healthy term-born infants.
- There was significant association between computer-based video analysis and temporal organization of fidgety movements.
