Development of FascialSense: A Smart Low-Cost Optical Fiber Based Sensor for Fascial Densification Detection

Area of Science:

• Biomedical Engineering
• Medical Devices
• Pain Management

Background:

• Myofascial Pain Syndrome (MPS) is often diagnosed through subjective, physician-dependent methods.
• Current diagnostic tools for fascial densification are often bulky and expensive.
• Objective and cost-effective methods are needed for detecting fascial abnormalities.

Purpose of the Study:

• To design and develop FascialSense, a novel handheld device for detecting fascial densification.
• To provide a technology-driven tool for identifying Myofascial Pain Syndrome (MPS) related fascial changes.
• To overcome limitations of current subjective and costly diagnostic approaches.

Main Methods:

• The FascialSense device utilizes macrobending of a plastic optical fiber embedded in a resin probe.
• Changes in transmitted light intensity correlate with resin deformation, indicating fascial densification.
• Calibration and characterization were performed using a striated phantom with static loading tests.

Main Results:

• The FascialSense device demonstrated a sensitivity of 0.0947 V/N during calibration.
• The device successfully detected fascial densification points and constrictions.
• The technology offers a viable, cost-effective alternative for clinical use.

Conclusions:

• FascialSense provides a novel, objective, and cost-effective method for detecting fascial densification.
• The device has the potential to improve the diagnosis and management of Myofascial Pain Syndrome.
• This technology-driven tool can be integrated into clinical settings for improved patient care.
