Cardiopulmonary rehabilitation should be started early for these patients. Modified transdermal ILIBm (Intravascular Laser Irradiation of Blood) is a blood and systemic photobiomodulation therapy that may contribute to improvement in general conditions and rehabilitation after infection. The objective of this study was to evaluate the efficacyof the use of transdermal ILIBm in the radial artery associated with cardiopulmonar rehabilitation in post-COVID-19 patients. This is a randomized controlled clinical trialwith 12 volunteers of both sexes. We divided into 2 randomized groups, ILIBm groupwith 30 minutes irradiation and the cardiopulmonary rehabilitation and compared withthe control group ILIBm off and the cardiopulmonary rehabilitation, evaluated beforeand after the program. The interventions were performed 2x per week for 4 weeks. Peak expiratory flow, Walk Test (6 min), Dynamometry, Muscle Strength (MRC), Quality of life (SARC-VIDA software, which is based on the SF-36 questionnaire), andbiochemical and hematological tests were evaluated. The rehabilitation program consisted of aerobic exercises, resistance training, and respiratory training. The resultsobtained in the intergroup analysis showed non-significant statistics, in the intragroupanalysis significant positive results in the ILIBm group, with improvement in musclestrength by dynamometry, in peak expiratory flow, in the BORG scale during the 6-minute walk test and in quality of life in the vitality and functional capacity parameters.Even with some statistically insignificant results, 100% of the participants reported atthe end improvement of symptoms or even disappearance in both groups. Weconclude that cardiopulmonary rehabilitation is necessary in patients convalescingfrom post-covid-19 syndrome and when associated with ILIBm showed greater resultsin the parameters of muscle strength, peak expiratory flow, 6-minute walk test andquality of life.pdfFotobiomodulaçãoLaser de baixa potênciaCOVID-19Reabilitação pulmonarBioengenhariaDissertaçãoEngenharia BiomédicaBioengenharia
