DxToniaNet estimates leg dystonia severity from 2D clinical videos in 298 children with cerebral palsy, achieving MAE 1.71 and 90–94% accuracy versus expert GDRS ratings.
- Why it matters: Leg dystonia affects 50–80% of children with cerebral palsy, yet severity scoring is subjective and slow, limiting consistent clinical care and trial outcome measurement.
- What they did: Using OpenPose-derived knee, ankle, and toe coordinates plus 69 variance and amplitude features, a deep neural network was trained with 5-fold cross-validation on Center 1 and tested on independent Center 2 videos.
- The result: On Center 2 testing, DxToniaNet produced MAE 1.71 {+/-} 1.68 and RMSE 2.21 {+/-} 0.34, with 90–94% accuracy for separating videos with >4-point GDRS differences.
