PBMT ndi chithandizo cha kuwala kwa laser kapena LED chomwe chimathandiza kukonza minofu (mabala a pakhungu, minofu, tendon, mafupa, mitsempha), chimachepetsa kutupa ndikuchepetsa ululu kulikonse komwe kuwalako kumagwiritsidwa ntchito.
PBMT yapezeka kuti imathandizira kuchira msanga, kuchepetsa kuwonongeka kwa minofu komanso kuchepetsa kupweteka pambuyo pochita masewera olimbitsa thupi.
Mu nthawi ya Space Shuttle, NASA inkafuna kuphunzira momwe zomera zimakulira mumlengalenga. Komabe, magwero a kuwala omwe amagwiritsidwa ntchito kulima zomera pa Dziko Lapansi sankakwaniritsa zosowa zawo; ankagwiritsa ntchito mphamvu zambiri ndipo ankapanga kutentha kwambiri.
M'zaka za m'ma 1990, Wisconsin Center for Space Automation & Robotics inagwirizana ndi Quantum Devices Inc. kuti ipange gwero lothandiza kwambiri la kuwala. Anagwiritsa ntchito ma LED (ma LED) popanga zinthu zawo, Astroculture3. Astroculture3 ndi chipinda chokulirapo zomera, chomwe chimagwiritsa ntchito magetsi a LED, omwe NASA idagwiritsa ntchito bwino pa maulendo angapo a Space Shuttle.
Posakhalitsa, NASA inapeza njira zomwe zingagwiritsidwe ntchito powunikira kuwala kwa LED osati pa thanzi la zomera zokha, komanso kwa oyenda mumlengalenga okha. Kukhala m'malo otsika mphamvu yokoka, maselo a anthu sabadwanso msanga, ndipo oyenda mumlengalenga amataya mafupa ndi minofu. Chifukwa chake NASA inayamba kugwiritsa ntchito njira yowongolera kuwala (PBMT). Njira yowongolera kuwala imatanthauzidwa ngati njira yowunikira yomwe imagwiritsa ntchito magwero a kuwala osapanga ma ioni, kuphatikiza ma laser, ma diode otulutsa kuwala, ndi/kapena kuwala kwa broadband, mu spectrum yowoneka (400 - 700 nm) ndi near-infrared (700 - 1100 nm) yamagetsi. Ndi njira yosatentha yomwe imakhudza ma chromophores amkati omwe amachititsa zochitika za photophysical (monga, linear ndi nonlinear) ndi photochemical pamlingo wosiyanasiyana wachilengedwe. Njirayi imabweretsa zotsatira zabwino zochizira kuphatikizapo koma osati zokhazo zochepetsera ululu, kusintha kwa chitetezo chamthupi, komanso kulimbikitsa kuchira kwa mabala ndi kukonzanso minofu. Mawu akuti njira yowongolera kuwala (PBM) tsopano akugwiritsidwa ntchito ndi ofufuza ndi akatswiri m'malo mwa mawu monga njira yowongolera kuwala ya low level (LLLT), njira yowongolera kuwala, kapena njira yowongolera kuwala.
Zipangizo zochizira kuwala zimagwiritsa ntchito mitundu yosiyanasiyana ya kuwala, kuyambira kuwala kosaoneka, komwe kuli pafupi ndi infrared kudzera mu spectrum yowoneka (yofiira, yalanje, yachikasu, yobiriwira, ndi yabuluu), kuyima asanafike kuwala koopsa kwa ultraviolet. Pakadali pano, zotsatira za kuwala kofiira ndi komwe kuli pafupi ndi infrared ndizo zomwe zaphunziridwa kwambiri; kuwala kofiira nthawi zambiri kumagwiritsidwa ntchito pochiza matenda a pakhungu, pomwe pafupi ndi infrared kumatha kulowa mkati kwambiri, kudutsa pakhungu ndi mafupa komanso ngakhale muubongo. Kuwala kwa buluu kumaganiziridwa kuti ndi kwabwino kwambiri pochiza matenda ndipo nthawi zambiri kumagwiritsidwa ntchito pa ziphuphu. Zotsatira za kuwala kobiriwira ndi kwachikasu sizikumveka bwino, koma wobiriwira ukhoza kusintha kuchuluka kwa pigmentation, ndipo wachikasu ungachepetse kuwala kwa photoaging.
