A Cheap Way to Check Nerve Health in Leprosy

The Challenge

Leprosy can significantly impact the nerves that regulate essential functions like sweating and blood flow. However, assessing these nerves is both complex and costly.

The Innovation

A recent study explored the potential of a simple infrared camera to evaluate nerve function. The method involves measuring how quickly hands warm up after being submerged in cold water, which could indicate nerve health.

The Process

• Researchers developed a specialized setup to stabilize hands and a computer program to monitor temperature changes.
• The infrared camera's accuracy was compared to a high-end lab sensor, showing promising results with minor discrepancies.
• The study also examined the influence of the tester on results, finding minimal impact.
• However, when the same individuals were tested over five days, significant variations in warming speed were observed.

The Outlook

While the test shows potential, its reliability remains uncertain. The infrared camera offers a cost-effective and user-friendly solution, but further research is needed to determine its effectiveness in diagnosing nerve damage in leprosy and other conditions.
