High-Density Surface EMG (HDsEMG)

Reference: Gallina et al., 2022

The matrix is organized according to three main applications of the technique (regional activation, muscle fibre properties, and single motor unit activity), for each we included general considerations and definitions, recommendations on electrode montage, type and configuration, location and orientation, data analysis and interpretation.

• Advantages: Captures spatial distribution of muscle activity, enables motor unit decomposition, and can track changes in muscle activity over time.
• Limitations: Signal quality may be affected by subcutaneous tissue thickness, and proper electrode placement is critical.
