Automatic analysis of electromyography (EMG) has evolved significantly since the 1950s, with modern machines offering advanced signal processing. Research continues to explore sophisticated techniques and artificial intelligence for deeper insights into muscle and nerve function.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Signal Processing

Context:

  • Electromyography (EMG) signal analysis has a history dating back to analog machines in the 1950s.
  • Significant advancements occurred from the 1980s onward due to the advent of fast computers and sophisticated software.
  • Modern EMG machines offer a range of automated analysis programs.

Purpose:

  • To provide an overview of the evolution and current capabilities of automatic electromyography (EMG) signal analysis.
  • To highlight the transition from analog to digital processing in EMG.
  • To differentiate between commercially available and research-oriented EMG techniques.

Summary:

  • Early EMG analysis in the 1950s utilized analog machines.
  • The 1980s marked a turning point with the integration of fast computers, enabling advanced analyses like response area, latency measurement, wave averaging, motor unit potential sorting, jitter computation, and spectral analysis.
