How external factors affect 2D-NIRS tissue oxygenation measurements in healthy volunteers
This study tests how things like temperature, activity, caffeine, and nicotine influence 2D-NIRS measurements of tissue oxygenation in healthy adults.
-
Photobiomodulation to Help Spasticity After Stroke
This trial tests whether matching low-level light therapy can reduce leg muscle tightness in adults who have had a stroke and developed spasticity.
-
POP-Score: A simple, non-invasive test to see if newborns might have early infection
This study tests whether the POP-Score, a non-invasive measure using NIRS and routine vitals, can predict elevated CRP in term and near-term neonates within 48 hours of birth.
-
Kidney-surface versus limb NIRS monitoring to predict acute kidney injury after cardiac surgery with bypass
This study will try NIRS sensors placed over the kidneys versus on the limbs to see which better predicts acute kidney injury in adults having cardiac surgery with cardiopulmonary bypass.
