Effect of PBM on Functional Capacity and Fatigability in Post Covid-19 Elderly

A Comparative Study Between Photobiomodulation and Placebo on Functional Capacity and Fatigability in Post Covid-19 Elderly

Participants had randomly divided into two equal groups. Group (A) which is the study group will receive photobiomodulation session two times per week for four weeks. Group (B) will be the control group that will receive placebo photobiomodulation two times per week for four weeks.

group (A): Each participant will sign a consent form after receiving a detailed explanation about the procedure. submaximal exercise capacity using time up and go test will be assessed. fatigability will be assessed using fatigue assessment scale. hemodynamic variables including; Blood pressure, heart rate, oxygen saturation, maximum oxygen consumption will also be assessed. After one month all the assessment procedure will be repeated again. r group (B): Each participant will sign a consent form after receiving a detailed explanation about the procedure. submaximal exercise capacity using time up and go test will be assessed. fatigability will be assessed using fatigue assessment scale. hemodynamic variables including; Blood pressure, heart rate, oxygen saturation, maximum oxygen consumption will also be assessed. After one month all the assessment procedure will be repeated again.

participants will divided into two equal groups , group A will receive photobiomodulation sessions and group B will receive placebo photobiomodulation

Photobiomodulation (PBM) describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying.
