Measurement of camptocormia trunk flexion using a dual-sensor measurement setup

Area of Science:

• Biomedical Engineering
• Clinical Biomechanics
• Rehabilitation Medicine

Background:

• Accurate assessment of trunk flexion is vital for camptocormia patient management.
• Current methods using photographs or videos have limitations in capturing dynamic patient compensation.
• Developing objective and reliable measurement tools is essential for effective camptocormia therapies.

Purpose of the Study:

• To introduce a novel, simple measurement setup using two accelerometers to quantify trunk flexion in camptocormia patients.
• To evaluate the accuracy of the proposed accelerometer-based method against established visual assessment techniques.

Main Methods:

• A two-sensor measurement system utilizing accelerometers was developed.
• The system measures trunk flexion angle, adhering to the established perpendicular measurement method.
• Performance was validated against a motion capturing system for visual assessment.

Main Results:

• The proposed accelerometer method demonstrated a low average deviation of -1.74° compared to visual assessment.
• Maximum deviations observed were +2° and -6°, indicating good accuracy.
• The system effectively measures the camptocormia angle, accounting for patient's dynamic capabilities.

Conclusions:

• The two-accelerometer setup offers a reliable and accurate method for assessing trunk flexion in camptocormia.
• This innovative approach provides a valuable tool for developing and monitoring camptocormia therapies.
• The method's simplicity and accuracy make it suitable for clinical application.
