Reliability of an algometry device for pain pressure threshold evaluation in athletes: A pilot study

Area of Science:

• Biomedical Engineering
• Pain Research
• Rehabilitation Science

Background:

• The pain pressure threshold (PPT) is crucial in diagnostics and rehabilitation.
• Manual PPT measurement using algometers is prone to human error.
• Automated PPT measurement can improve accuracy and consistency.

Purpose of the Study:

• To develop and validate a prototype device for automated PPT measurement.
• To assess the reliability and accuracy of the automated device.
• To compare PPT between males and females using the new device.

Main Methods:

• A novel automated pressure application device was designed.
• The device was tested on the rectus femoris of 41 participants.
• Intra-class correlation (ICC) was used to assess device reliability.

Main Results:

• The prototype device demonstrated high reliability (ICC = 0.91).
• The standard error of measurement was 4.34.
• Males exhibited a significantly higher pain pressure threshold than females.

Conclusions:

• The automated device offers a reliable method for PPT measurement with minimal examiner intervention.
• The findings suggest sex-based differences in pressure pain sensitivity.
• This technology has potential applications in clinical and research settings.
