PhotoBioModulation (PBM) stands as a pivotal technique in clinical applications, yet its efficacy relies heavily on precise energy density measurement. Unfortunately, existing measurement tools often lack accuracy in defining therapeutic windows for both BioStimulation and BioInhibition, thus constraining their availability in the market. To address this challenge, this study introduced PBM attachments for diode lasers, employing Plano-Concave Lenses for Cone-type attachment to regulate spot size and ensure consistent energy distribution for BioStimulation.

By leveraging clear resin materials and advanced 3D printing technology, three attachment models were meticulously crafted with optimization design techniques, facilitating precise measurement of power density and energy density. Notably, the Cylinder-type attachment exhibited significant effectiveness in alleviating joint pain through BioInhibition, particularly when targeting specific acupuncture points, as validated by the Visual Analog Scale (VAS). Remarkably, substantial pain and swelling relief were observed within a matter of days to weeks following treatment.

Achieving effective BioStimulation and BioInhibition mandates meticulous control over energy density, a critical factor for optimal PBM performance. Moreover, to enhance durability and longevity, the study advanced towards developing new attachments using aluminum alloy, ensuring superior maintenance and prolonged lifespan. With these innovative attachments, clinicians can now attain enhanced precision in energy density measurement, thereby fostering improved outcomes in PBM therapy.
