[Diagnostic method in occupational vegetative trophic dysfunction of upper limb muscles]

Area of Science:

• Biomedical Engineering
• Occupational Health
• Sports Science

Background:

• Assessing muscular contractility is crucial for evaluating functional status and detecting early signs of fatigue.
• Existing methods may be time-consuming or not suitable for rapid, large-scale assessments.

Purpose of the Study:

• To present a novel, certified method for assessing muscular contractility and fatigue.
• To evaluate the functional state of muscles through force and quickness measurements.
• To provide a tool for assessing the impact of work conditions on hand muscle health.

Main Methods:

• Digital compression transducer used to record force and quickness curves over 30 seconds at 80 compressions per minute.
• Measurement of force and quickness at specific movement points.
• Estimation of muscle contraction and relaxation times.

Main Results:

• The method successfully captures parameters of muscular contractility.
• It allows for comparison of contractility parameters and functional state evaluation.
• Reduced quickness of contraction was identified as an indicator of muscular fatigue.

Conclusions:

• The developed method provides a reliable means to assess muscle contractility and fatigue.
• Its applicability in workshops and for mass screening aids in evaluating occupational health.
• The method is certified and demonstrates practical utility for monitoring worker hand health.
