Area of Science:

  • Biomedical Engineering
  • Signal Processing

Context:

  • Electromyography (EMG) signal detection is prone to artifacts.
  • Artifacts can distort muscle activity measurements.

Purpose:

  • To introduce novel methods for suppressing artifacts in EMG signals.
  • To improve the accuracy of EMG-based muscle activity detection.

Summary:

  • Two artifact suppression methods utilizing an adaptive threshold are presented.
  • The threshold is dynamically adjusted based on preceding muscle activity.
  • These methods effectively identify and remove even minor artifacts without significantly altering the detected muscle activity.

Impact:

  • Provides effective, simple, and easily implementable solutions for EMG artifact reduction.
