Providing physical relief for nurses by collaborative robotics.

Area of Science:

• Biomedical Engineering
• Occupational Health
• Robotics

Background:

• Manual patient handling poses significant musculoskeletal risks for healthcare workers.
• Traditional techniques often fail to accommodate individual physical capacities.
• Need for innovative solutions to mitigate physical burden in nursing care.

Purpose of the Study:

• To evaluate a collaborative robotic system for assisting nurses in manual patient handling.
• To quantify the impact of robotic assistance on physical strain and movement patterns.
• To assess the feasibility of robot-assisted patient handling in reducing musculoskeletal burden.

Main Methods:

• Utilized a collaborative robotic system to assist nurses with patient handling tasks.
• Quantified kinetic and muscle activity data to analyze movement patterns.
• Measured force exertion, trunk lateral flexion, and trunk torsion.
• Assessed mean spine muscle activity during patient handling procedures.

Main Results:

• Collaborative robotics reduced maximum force exertion by up to 51%.
• Trunk lateral flexion and torsion were reduced by up to 54% and 87%, respectively.
• Mean spine muscle activity decreased by up to 55% with robotic assistance.
• Identified distinct movement patterns correlating with muscle activity extremes.

Conclusions:

• Collaborative robot-assisted patient handling is feasible and effective.
• Robotic systems significantly reduce physical burden and improve biomechanics for nurses.
• Highlights the potential for individualized interventions to prevent occupational musculoskeletal disorders.
