Mester yabanje kwita ubu buryo "laser biostimulation", ariko bidatinze yaje kumenyekana nka "low-level laser therapy" cyangwa "red light therapy". Ubwo abashakashatsi kuri ubu buryo bahinduraga diode zitanga urumuri, bwaje kumenyekana nka "low-level light therapy", kandi kugira ngo hakemurwe urujijo ku gisobanuro nyacyo cy'ijambo "low-level", havutse ijambo "photobiomodulation".
