Area of Science:

• Neuroscience
• Biomechanics
• Rehabilitation Engineering

Background:

• The tapping test is a common method for assessing finger dexterity, speed, and motor coordination.
• Understanding neuromuscular and biomechanical factors, alongside brain activation, is crucial for fine motor control.
• Neuroplastic adaptation to repetitive movements highlights the brain's ability to change.

Purpose of the Study:

• To propose a novel measurement architecture for objective evaluation of physiological aspects related to finger dexterity.
• To assess coordinative and conditional capabilities using a new protocol and wearable sensors.
• To provide advanced data analysis for a comprehensive understanding of tapping test results.

Main Methods:

• Development of a novel measurement protocol for assessing participants' coordinative and conditional capabilities.
• Implementation of a measurement platform with synchronized, non-invasive inertial sensors worn at the finger level.
• A data analysis processing stage designed to deliver extensive information beyond traditional tapping test outcomes.

Main Results:

• The proposed architecture provides objective evaluation of finger dexterity, motor coordination, and neuroplasticity.
• Demonstrated the importance of interdigital autonomy in complex finger movements.
• Proof-of-concept testing with college students validated the system's potential.

Conclusions:

• The developed measurement architecture offers a valuable tool for assessing and improving motor abilities.
• Findings deepen the understanding of upper limb coordination and neuroplasticity.
• The system shows promise for applications in monitoring neurodegenerative disease progression.
