PBM onderzoek
More than 7,000 studies with photobiomodulation (PBM) (also called red light therapy) have now been carried out, including in vitro studies, animal studies, and human studies. These studies are tracked as comprehensively as possible in the database of Heiskanen.
Analysis of this database shows that research has been conducted within 24 different medical specialisms.
Specialisms in the Heiskanen database:
| Cardiology and hemotology | Gynecology and urology | Otorhinolaryngology |
| Dentistry | Infectious diseases | Pain medicine |
| Dermatology | Neurology | Plastic surgery |
| Emergency medicine | Neurosurgery | Psychiatry |
| Veterinary | Oncology and supportive care | Pulmonology |
| Gastroenterology | Opththalmology | Rheumatology |
| General health | Oral and maxillofacial surgery | Sleep medicine |
| General surgery | Orthopedics | Veterinary medicine |
Most of the research in this database was carried out in Brazil (1600+), followed by the United States (800+). China and Iran follow at a distance (together 400+). The Netherlands is among the countries where relatively little research has been conducted, with 26 studies as of 15 July 2026.
