[Research progress on electromyographic methods for sustained low-intensity muscle fatigue detection]

Area of Science:

• Neurophysiology
• Occupational Health
• Biomedical Engineering

Background:

• Sustained low-intensity muscle fatigue (SULMF) is a common cause of occupational musculoskeletal pain.
• It involves muscle contractions below 10% of maximum voluntary contraction, leading to reduced function.
• The objective detection of SULMF using surface electromyography (sEMG) is debated.

Purpose of the Study:

• To elucidate the neurophysiological mechanisms and hypotheses underlying SULMF.
• To review current research on electromyography detection indicators for SULMF.
• To assess the progress in electromyography detection methods for SULMF.

Main Methods:

• Literature review of neurophysiological mechanisms.
• Analysis of electromyography detection indicators and methods.
• Synthesis of research progress in SULMF detection.

Main Results:

• The neurophysiological basis of SULMF is complex and requires further investigation.
• Electromyography shows potential for SULMF detection, but standardized indicators and methods are lacking.
• Current research highlights variability in electromyography responses to SULMF.

Conclusions:

• Accurate and objective detection of SULMF is crucial for preventing work-related musculoskeletal disorders.
• Further research is needed to validate electromyography techniques for reliable SULMF assessment.
• Improved detection methods will aid in early diagnosis and targeted interventions for occupational pain.
