NCT05647304

Brief Summary

This is a controlled investigation, with randomization of the patients, which aims at evaluating the safety and performance of device RGn550 in treating sportspeople suffering from acute concussion syndrome. RGn550 is a non-invasive medical device which is applied on the head (helmet). It combines 2 technologies:

  • PhotoBioModulation (PBM), which involves exposure to light from the red to near-infrared wavelengths using lasers and Light Emitting Diodes (LEDs)
  • Static Magnetic Stimulation (SMS), which consists in the application of a static magnetic field. Considering previous investigations, this innovative technology could reduce brain inflammation implicated in concussion syndrome.

  • Who provided a dated and signed informed consent form.
  • Patient protected by a French legal measure ("sauvegarde de justice", "tutelle" or "curatelle")
  • Patient not able to express his/her consent
  • Patient deprived of liberty or hospitalized without consent
  • Woman who is pregnant or breastfeeding, or who plans to become pregnant or breastfeeding during the investigation, or who has the capacity to conceive but is not using a reliable contraceptive method as deemed by the investigator
  • Patient living in a medical facility
  • Patient with skin lesions on the treatment application area (head)
  • Patient with a short-term life-threatening pathology (e.g., evolving cancer; non-stable heart failure; severe hepatic, renal or respiratory failure, etc.)
  • Patient implanted with ferromagnetic material
  • Patient implanted with a pacemaker
  • Patient with a risk of epileptic seizure or other non-degenerative central nervous system diseases
  • Patient with major physical or neurosensorial disorders that may interfere with assessments
