Summary
Choosing the right electromyography (EMG) technique is crucial. This review compares surface EMG (sEMG, HD-sEMG) and intramuscular EMG (MMU, SMU), guiding researchers to select the best method for their specific muscle activation studies.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Kinesiology
Background:
- Electromyography (EMG) is vital for quantifying muscle activation.
- Various EMG techniques exist, including surface (sEMG, HD-sEMG) and intramuscular (MMU, SMU) recordings.
- Understanding the strengths and limitations of each technique is essential for accurate research.
Purpose of the Study:
- To provide a comprehensive comparison of different EMG recording techniques.
- To guide researchers in selecting the most appropriate EMG method based on their specific objectives.
- To highlight the nuances, strengths, and limitations of sEMG, HD-sEMG, MMU, and SMU.
Main Methods:
- Review of existing literature on EMG techniques.
- Analysis of signal characteristics, including temporal changes, amplitude, and synchronisation.
- Evaluation of factors affecting signal quality, such as electrode placement, signal cancellation, crosstalk, and motion artifacts.
- Discussion of electrode impedance changes over time.
Main Results:
- MMU is ideal for deep/small muscles in static/dynamic activities due to high sensitivity and reduced artifact impact.
- sEMG is suitable for short, isometric assessments of large, superficial muscles.
- HD-sEMG aids in studying single motor unit properties under isometric conditions.
- SMU is best for investigating neuronal networks.
Conclusions:
- The choice of EMG technique should be dictated by specific research goals.
- Each technique (sEMG, HD-sEMG, MMU, SMU) offers unique advantages for different experimental designs and muscle types.
- Proper selection ensures optimal data integrity and interpretation in muscle activation studies.
