Abstract

PhotoBioModulation (PBM) is an important technique for clinical applications, but its efficacy depends on the accurate measurement of energy density. Unfortunately, current measurement tools have not been able to provide precise therapeutic windows for BioStimulation and BioInhibition, which limits their availability on the market. To address this issue, this study developed PBM attachments for Diode Lasers, which use Plano-Concave Lenses to regulate spot size and distribute energy evenly for BioStimulation. Using clear resin materials and 3D printing, three attachment models were created, allowing for accurate measurement of power density and energy density. The Cylinder-type attachment was found to effectively reduce joint pain through BioInhibition, with specific acupuncture points proving more effective than trigger points, as measured by the VAS. Pain relief was significantly improved within one to two months of treatment. Effective BioStimulation and BioInhibition require precise energy density, which is critical for optimal PBM performance. With these new attachments, clinicians can achieve more precise measurements of energy density, allowing for improved outcomes in PBM therapy.
