The Effect of Light Therapy on Post-Surgical Pain
NCT03674697 · View on ClinicalTrials.gov ↗
Study Summary
This is a prospective randomized clinical trial study to investigate two main aspects. The first aspect is to investigate the efficacy exposure to green light emitting diode (GLED) in reducing postoperative opioid medications requirements by 20% as the primary outcome amongst patients scheduled for elective total knee replacement surgery (knee arthroplasty). The second aspect is to reduce postoperative pain by 30%, improve preoperative anxiety by 30%, and improve the quality of sleep pre and postoperatively by 30%. Seventy participants scheduled for elective unilateral primary total knee arthroplasty (total knee replacement) will be recruited from the pain clinic or from the orthopedic surgery clinics at Banner-University Medical Center by the pain or orthopedic physicians who are key personnel of this study. Once a participant is identified, he/she will meet with one of the research team members to explain the nature of the clinical trial and undergo a standard of care medical history gathering and baseline physical examinations. If the participant meets all the inclusion and have no exclusion criteria, he/she will be presented with a written consent in English to explain all the risk and benefits of this clinical trial. Once a participant signs a consent, he or she will be randomized by the study statistician, in a 1:1 ratio to either a GLED group (treatment) or white light-emitting diode (WLED) group (control). The participant will be trained on how to use the light device by one of the research team members. All participants will be exposed to either GLED or WLED for 8 weeks prior to surgery and two additional weeks after surgery.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03674697
The ClinicalTrials.gov registry entry for NCT03674697 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 70 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Arizona, which has 379 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Acute Pain appearing as the primary indexed condition, and to 2 interventions — of which Green LED light therapy is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03674697 reports 1 study location spanning 1 distinct geographic area — top geographies include Arizona. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
