He founded the Brazilian startup Bright Photomedicine and is one of the authors of the article “Pilot study of the effect of therapeutic photobiomodulation on postoperative pain in knee arthroplasty”, published in Brazilian Journal of Anesthesiology, in 2022.

Abstract: Nine participants undergoing primary TKA submitted to spinal anesthesia, sedation, ultrasound-guided obturator and Femoral nerve Block analgesia, and photobiomodulation Therapy (FBMT) were evaluated regarding postoperative pain and morphine consumption. FBMT sessions were performed in the Immediate Postoperative period (IPO) and after 24 hours. Participants received 16.7±15 mg of morphine up to the third postoperative day. At IPO, mean pain score was 4.8 ± 3.2 and 5.6 ± 3.5, at rest and on movement, respectively. Photobiomodulation therapy can be considered an option for mitigating pain for patients undergoing TKA.
