The study was planned to examine the effects of technology-supported yoga and exercise on chemotherapy-induced peripheral neuropathy and pain in children aged 5-18 years with leukemia.

It was planned to include all patients who were selected by the block randomization method, and who met the sampling criteria, in the study. Yoga will be given to the intervention group online. The control group will not be interfered with. Follow-up will be made using data collection tools after taking the study, 3 months later, and 6 months later.

Before starting yoga, "How are you feeling today?" will be asked to child. The yoga session will be individualized according to how the child feels. The content of the yoga sessions will progress in the form of warm-up exercises - breathing work - yoga postures (asana) - meditation - and progressive muscle relaxation exercises. Yoga sessions will be scheduled for 30 minutes. Yoga sessions and progressive muscle relaxation exercises will be held online once a week for eight weeks, then every two weeks for four months.
