Biosignal-based relaxation evaluation of head-care robot
Summary
A new head care robot offers significant relaxation, comparable to human nurses. This robot effectively reduces sympathetic nervous system activity and increases parasympathetic activity, promoting well-being.
Area of Science:
- Biomedical Engineering
- Robotics
- Physiology
Background:
- Head care procedures like scalp massages offer relaxation but pose physical strain on practitioners.
- Developing automated solutions for therapeutic procedures is crucial to mitigate practitioner burden.
Purpose of the Study:
- To quantitatively evaluate the relaxation effects of a newly developed head care robot.
- To compare the robot's efficacy against relaxation provided by human nurses using biosignal analysis.
Main Methods:
- Utilized biosignals including accelerated plethysmography (SDNN, HF/TP, LF/HF), heart rate (HR), blood pressure, salivary amylase (sAA), and peripheral skin temperature (PST).
- Conducted comparative analysis between head care provided by the robot and human nurses on 54 subjects.
- Measured changes in autonomic nervous system activity before and after interventions.
Main Results:
- The head care robot demonstrated significant changes in five key indexes: HF/TP, LF/HF, HR, sAA, and PST.
- Observed a decrease in sympathetic nervous system activity (indicated by reduced LF/HF, HR, sAA).
- Observed an increase in parasympathetic nervous system activity (indicated by increased HF/TP, PST).
Conclusions:
- The developed head care robot effectively induces relaxation, comparable to human practitioners.
- The robot significantly modulates autonomic nervous system balance, promoting relaxation within a short duration (5 minutes).
- This technology presents a viable solution to reduce practitioner burden while delivering therapeutic benefits.
