Background:

Early diagnosis and intervention are critical for managing cerebral palsy (CP).
Existing deep learning models for CP prediction often overlook crucial infant movement frequency data.
There is a need for efficient, interpretable, and accessible CP prediction systems, especially in resource-limited settings.

Purpose of the Study:

To develop an efficient and interpretable automatic system for early cerebral palsy prediction.
To investigate the utility of infant movement frequency in improving CP prediction accuracy.
To validate a novel deep learning approach using consumer-grade video data.

Main Methods:

Proposed a frequency attention-informed graph convolutional network (GCN) for CP prediction.
Developed a frequency-binning method to filter noise while retaining critical joint position data.
Validated the model on the MINI-RGBD and RVI-38 consumer-grade RGB video datasets.

Main Results:

The proposed frequency attention module significantly enhanced classification performance and system interpretability.
The frequency-binning method effectively preserved essential frequency information from joint position data.
Achieved state-of-the-art prediction performance on both MINI-RGBD and RVI-38 datasets.

Conclusions:

Frequency information of infant movement is highly effective for non-intrusive CP prediction.
The developed AI system offers a promising tool for early cerebral palsy diagnosis.
This approach can support early CP diagnosis in resource-limited regions lacking abundant clinical resources.
