Advances in surface EMG: recent progress in clinical research applications

Area of Science:

• Biomedical Engineering
• Clinical Neurophysiology

Background:

• Surface electromyography (sEMG) is a key tool in understanding neuromuscular function.
• Previous reviews have covered sEMG detection, processing, and neurorehabilitation, but a comprehensive update on clinical applications is needed.

Purpose of the Study:

• To review the state-of-the-art applications of surface EMG techniques in clinical research.
• To identify gaps in current knowledge and suggest future research directions in specific application areas.

Main Methods:

• Comprehensive literature review of recent advancements in surface EMG applications.
• Focus on clinical research, including external anal sphincter function, postural control, exercise physiology, and ergonomics.

Main Results:

• Detailed overview of sEMG applications in assessing external anal sphincter function related to episiotomy and incontinence.
• Exploration of sEMG's role in evaluating postural control mechanisms.
• Discussion of sEMG in exercise physiology, electrical stimulation, muscle cramps, and work-related neuromuscular disorders.
• Identification of areas requiring further investigation and research.

Conclusions:

• Surface EMG continues to be a valuable technique with expanding clinical applications.
• Further research is needed to fully leverage sEMG for diagnosing and managing conditions related to incontinence, postural instability, and occupational health.
