Microsensor for localization of pain sources

Important results from the project

The project goal of developing a micro-sensor for the localization of tissue anomalies associated with chronic musculoskeletal pain was accomplished. The sensor is a medical device that measures both oxygen content and conductivity of muscular tissues, and we are in the process of applying for approval for a clinical trial of the device. As well, a clinical study was performed where biochemical properties of muscular tissues associated with chronic pain was investigated, which has provided valuable insight into the nature of the chronic pain sources.

Expected long term effects

A micro-sensor that is capable of simultaneously measuring the oxygen content and conductivity of muscular tissues was developed, and it is expected that this medical device will aid the clinician in a more accurate identification and diagnosis of chronic musculoskeletal pain. As well, the results from the clinical study performed during the project involving patients with chronic pain are expected to help in future improvements and development of the micro-sensor as it undergoes clinical trials in the upcoming months.

Approach and implementation

The first clinical trial in the project was modified to only investigate the biochemical properties of tissues from patients with chronic pain, and not test the initial sensor prototype due to the requirement for clinical trials of our device. Additionally, the pandemic situation resulted in a delay in the start and a later finish for the clinical study. As a result, in parallel with the clinical study, more resources were directed to the development of the final sensor and the preparation of the application for the clinical trial of the device.
