Surface electromyography (SEMG) analysis offers advanced tools for muscle assessment. This study reviews processing methods to ensure consistent and comparable results in research.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Rehabilitation Science

Background:

  • Surface electromyography (SEMG) is widely used for muscle function assessment, pathology identification, and ergonomics.
  • Advanced signal processing, particularly in the spectral domain, enhances SEMG analysis capabilities.
  • Inconsistent reporting and application of processing methods hinder result comparability across studies.

Purpose of the Study:

  • To review and discuss various processing methods for surface electromyography signals.
  • To highlight variations in methods, underlying assumptions, and their impact on SEMG analysis.
  • To explore how extracted SEMG parameters relate to physiological modifications like muscle force and fiber type.

Main Methods:

  • Comprehensive review of signal acquisition and processing techniques in SEMG.
