Background & aim: Due to the high prevalence of chronic non-specific back pain and its effects on daily activities and people's lifestyle, it is important to study about new treatment perspectives and therapeutic exercises for this disease. Therefore, the aim of the present study was to determine and evaluate the effect of eight weeks of exercises. It was based on prayer movements on the amount of pain and endurance of trunk flexor and extensor muscles in patients with non-specific chronic back pain. Methods: The present semi-experimental study was conducted in 2019. the research population included all patients with non-specific chronic back pain referred to Shahid Muftah Clinic No. 1 in Yasuj, Iran. Sixty-six eligible patients were selected by non-probability sampling method and were divided into two groups based on random block allocation: test (33 people) and control (33 people).

For the patients of the test group, exercises based on prayer movements were performed 3 times a week for 8 weeks, and no training was given to the control group. From the demographic data collection form and the Quebec back pain disability questionnaire, the visual pain measurement scale, the 60-degree body support test and the Byring Sorensen test to collect data before the intervention and immediately after the intervention from the visual measurement scale Pain, one week after the intervention, the body maintenance test at a 60-degree angle and Sorensen bearings were used. The collected data were analyzed using t-paired, Man-Whitney, independent t, Wilcoxon, chi-score and Shapiro-Wilk statistical tests. Results: At the starting point of the study, there was no significant difference between the groups under study in terms of the amount of pain and endurance of the trunk muscles, except for the endurance of the extensor muscles (p
