Background:

• Objective electromyography (EMG) is vital for evaluating jaw muscle capacity.
• Accurate measurement of motor unit potentials (MUPs) is essential for various EMG analyses.
• Current methods require precise and objective recording techniques for clinical applications.

Purpose of the Study:

• To develop and validate algorithms for semi-automatic detection and pattern recognition of MUPs.
• To introduce a novel parameter, 'maximal voltage increase per microsecond during the spike-phase', as a supplement to 'rise-time'.
• To demonstrate the utility of these algorithms in analyzing jaw muscle function.

Main Methods:

• Development of computer-aided algorithms for semi-automatic MUP detection.
• Utilizing a small computer system for EMG data analysis.
• Recording and analyzing MUPs from jaw muscles.

Main Results:

• Successful development of algorithms for semi-automatic MUP detection and pattern recognition.
• Identification of 'maximal voltage increase per microsecond during the spike-phase' as a valuable MUP parameter.
• Demonstrated application of the system for recording normative MUP values and recruitment patterns.

Conclusions:

• The developed algorithms provide an objective method for recording jaw muscle capacity using EMG.
• The new parameter enhances the analysis of MUPs, aiding in the study of muscle dysfunction and oral rehabilitation.
• This system facilitates research into the functional anatomy of jaw muscles through normative data collection.
