Advanced multiscale machine learning for nerve conduction velocity analysis.

This paper presents an advanced machine learning (ML) framework for precise nerve conduction velocity (NCV) analysis, integrating multiscale signal processing with physiologically-constrained deep learning. Our approach addresses three fundamental limitations of conventional NCV techniques: (1) oversimplified nerve fiber modeling, (2) temperature sensitivity, and (3) static measurement interpretation. The proposed framework combines: (i) entropy-optimized wavelet analysis for adaptive multiscale signal decomposition, (ii) thermodynamically-regularized neural networks incorporating Arrhenius kinetics, and (iii) stochastic progression models for uncertainty-aware longitudinal tracking. Through data extracted from prior studies in this field, rigorously validated across 1842 patients from 28 medical centers, we demonstrate significant improvements: 23.4% enhancement in motor NCV accuracy ([Formula: see text]) and 28.7% for sensory fibers. The framework maintains physiological interpretability while achieving superior performance through: (a) wavelet-optimized resolution scales (2-8 ms for motor, 0.5-2 ms for sensory fibers), (b) temperature compensation accurate to [Formula: see text] across 20-[Formula: see text], and (c) probabilistic progression tracking with 88.9% treatment response prediction accuracy. This work establishes new standards for ML applications in clinical neurophysiology by rigorously combining biophysical first principles with data-driven learning, offering both theoretical advances and immediate clinical utility for neuropathy diagnosis and monitoring.
