Using Pranayama and Deep Breathing Exercises to Reduce Cancer-Related Fatigue and Insomnia During Radiotherapy

Study sample The study population consisted of patients diagnosed with breast cancer, who received radiotherapy in the radiation oncology unit of a hospital in Ankara, between June 01, 2017 and January 31, 2019. At least three additional volunteers (16%) for each group were added, considering monitoring and data loss during the follow-up. Thus, the number of subjects was determined as 63 individuals (21 for each group). Of the 63 patients, one wanted to interrupt the treatment and two did not want to continue in the study, hence the study was concluded with 20 patients in each group (60 patients). Instruments Fatigue Visual Analog Scale (VAS) Score Piper Fatigue Scale (PFS) Insomnia Visual Analog Scale (VAS) Score Pittsburgh Sleep Quality Index (PSQI) Questionnaire on Patients' Opinions of the Exercises Patients in the pranayama, deep breathing exercise and control group were evaluated six times in terms of fatigue and insomnia VAS scores. PFS and PSQI were evaluated once prior to and after the 25-day session of radiotherapy treatment. Interventions Protocols for pranayama and deep breathing exercises were prepared Pranayama and Deep Breathing Exercise Groups: The patients were taught pranayama and deep breathing exercises by the researcher before the radiotherapy started. The patients were observed performing these exercises for 10 minutes after each radiotherapy session (25 days) accompanied by the researcher in a quiet room within the radiotherapy unit containing two couches and a chair. Control Group: The patients in this group did not receive any intervention.
