Background:

Myoelectric pattern recognition (MPR) is crucial for controlling myoelectric interface (MI) devices, including prosthetic and orthotic robots.
Current MIs offer advanced limb control and have potential in consumer electronics.
Non-stationary myoelectric signals cause performance degradation due to factors like electrode shifts and new users, necessitating frequent calibration.

Purpose of the Study:

To address the significant user calibration burden associated with conventional myoelectric interfaces.
To categorize scenarios that lead to calibration burdens, focusing on data distribution shifts and dynamic data categories.
To review and summarize robust MPR algorithms designed to alleviate user calibration requirements.

Main Methods:

Categorization of calibration burden scenarios based on data distribution shift and dynamic data categories.
Investigation and summarization of popular robust MPR algorithms.
Classification of algorithms based on data manipulation, feature manipulation, and model structure.

Main Results:

Identified common scenarios causing calibration burdens in myoelectric control.
Summarized robust MPR algorithms applicable to various scenarios.
Detailed the applicability and calibration requirements for each categorized algorithm.

Conclusions:

Robust MPR techniques offer significant advantages in reducing user calibration burden for myoelectric interfaces.
Remaining challenges include further improving algorithm robustness and adaptability.
Future opportunities lie in developing more intuitive and less burdensome MPR systems for enhanced user experience and broader application.
