Quantified reflex strategy using an iPod as a wireless accelerometer application

Area of Science:

• Neurology
• Biomedical Engineering
• Medical Devices

Background:

• Deep tendon reflex (DTR) testing is crucial for neurological evaluations.
• Assessing DTRs provides preliminary insights into nervous system status.
• Objective quantification of DTRs is needed for enhanced clinical assessment.

Purpose of the Study:

• To develop and evaluate a novel, quantified reflex strategy for DTR assessment.
• To utilize an iPod as a wireless accelerometer for reflex measurement.
• To establish an accurate and consistent method for quantifying the patellar tendon reflex.

Main Methods:

• An iPod was integrated with a potential energy device to evoke the patellar tendon reflex.
• The iPod functioned as a wireless accelerometer, recording the reflex response waveform.
• Data was wirelessly transmitted via email for post-processing and analysis.

Main Results:

• The quantified reflex strategy accurately captured the reflex response acceleration waveform.
• Maximum acceleration of the reflex response was identified as a key metric.
• The iPod-based accelerometer demonstrated consistent and accurate quantification of the reflex.

Conclusions:

• The developed quantified reflex strategy provides reliable DTR measurement.
• Using an iPod as a wireless accelerometer offers a practical approach for neurological assessment.
• This method enhances the objectivity and consistency of reflex testing.
