Evaluation of Hands-On Clinical Exam Performance Using Marker-less Video Tracking

Area of Science:

• Medical Education
• Biomedical Engineering
• Clinical Skills Assessment

Background:

• Evaluating hands-on clinical skills is crucial for medical training.
• Objective and quantitative assessment methods are needed to complement traditional evaluations.
• Marker-less video tracking offers a non-invasive approach to capture movement data.

Purpose of the Study:

• To investigate the feasibility of marker-less video tracking for evaluating hands-on clinical skills.
• To determine if hand motion kinematics can differentiate between various clinical scenarios and skill levels.
• To assess the potential of this technology in objective clinical skills assessment.

Main Methods:

• Experienced family practitioners performed simulated breast examinations.
• Marker-less video tracking software was employed to capture and analyze hand motion kinematics.
• Motion patterns were quantified and compared across different simulated pathologies and participants.

Main Results:

• Consistent practitioner motion patterns were observed across multiple simulated pathologies.
• Distinct characteristic motion patterns emerged for different pathologies during specific exam phases.
• The analysis revealed consistent inter-participant behavior, suggesting reliability.

Conclusions:

• Marker-less video kinematic tracking demonstrates potential for objective evaluation of clinical skills.
• The technology can discriminate between different examination procedures, clinicians, and pathologies.
• This approach offers a promising tool for enhancing medical training and skills assessment.
