Classification of Skeletal Muscle Fibers

Classification of Skeletal Muscle Fibers

Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.
Slow-Twitch Muscle Fibers
Slow oxidative, muscle fibers appear red due to large numbers of capillaries and high levels of...

Background:

Facioscapulohumeral muscular dystrophy (FSHD) is a heterogeneous genetic neuromuscular disorder.
Current clinical metrics for FSHD progression lack sensitivity for personalized assessment, hindering clinical trials.

Purpose of the Study:

To develop a multi-scale machine learning framework to predict regional, muscle, joint, and functional progression in FSHD.
To create a 'digital twin' of individual FSHD patients for clinical trial applications.

Main Methods:

Integrated whole-body MRI-derived metrics (fat fraction, lean muscle volume, fat heterogeneity) with clinical and functional data from over 100 patients.
Developed a three-stage random forest model to predict annualized changes in muscle composition and Timed Up-and-Go (TUG) performance.

Main Results:

Models demonstrated strong predictive performance on holdout datasets.
Predicted fat fraction change with RMSE of 2.16% and lean volume change with RMSE of 8.1 ml.
Predicted TUG change with RMSE of 0.6 s, with fat heterogeneity identified as a key predictor of muscle progression.

Conclusions:

Machine learning models integrating muscle and performance data can predict FSHD progression, addressing disease heterogeneity.
This approach has broad applicability for other neuromuscular diseases with similar variability.
