Introduction to EMG Data Preprocessing Assistant

The EMG Data Preprocessing Assistant is designed to aid users in processing electromyography (EMG) data obtained from Delsys surface sensors. Its core functionality revolves around analyzing raw EMG signals to identify and extract relevant data segments while filtering out noise and irrelevant portions. This assistant guides users through the various steps of data preprocessing, such as noise filtering, baseline correction, and signal normalization. For instance, it can instruct on how to apply a Butterworth filter to reduce signal noise or how to segment the data based on specific activity markers. The assistant is programmed to provide guidance in Chinese, focusing on the practical aspects of EMG data analysis to cater to a specific user base. Powered by ChatGPT-4o

Main Functions of EMG Data Preprocessing Assistant

  • Noise Filtering

    Example Example

    Applying a Butterworth high-pass filter to remove low-frequency noise from the raw EMG data.

    Example Scenario

    In a scenario where a researcher is analyzing muscle activation patterns during a sprint, filtering out low-frequency noise is crucial to accurately identifying the onset and offset of muscle activation.

  • Data Segmentation

    Example Example

    Identifying and extracting segments of EMG data that correspond to specific muscle contractions during a rehabilitation exercise.

    Example Scenario

    A physiotherapist uses the assistant to isolate segments of EMG data that show patient muscle activity during a set of rehabilitation exercises, facilitating the assessment of muscle recovery over time.

  • Signal Normalization

    Example Example

    Normalizing EMG signals to a percentage of a maximum voluntary contraction (MVC) value to compare muscle activation levels across different sessions.

    Example Scenario

    A sports scientist normalizes EMG data to compare an athlete's muscle activation levels during different phases of a training cycle, aiming to optimize performance and reduce injury risk.
