Background: Low back pain is one of the most significant musculoskeletal problems, causing various functional limitations that adversely affect individuals' quality of life. Objectives: The effect of combined Pilates-Kinsey and Mulligan-Kinsey exercises in women with non-specific chronic back pain has not been investigated. Methods: In the present quasi-experimental study, thirty women with non-specific chronic back pain with a range age of 35 - 65 years old were included in the study and were randomly divided into two Pilates-Kinesiotype (n = 15) and Mulligan-Kinesiotype (n = 15) groups. Exercise interventions were conducted for 6 weeks and 3 sessions per week. Pain, lumbar range of motion, hamstring stiffness and hip rotation were measured before and after the training intervention. Also, analysis of covariance (ANCOVA) test was used to analyze the data. Results: The results showed that there is a significant difference between the effect of Pilates-Kinesiotype training and Mulligan Kinesiotype training in the variables of pain, hamstring stiffness and hip rotation (P < 0.05) and the reduction of pain and hip rotation in the Pilates-Kinesiotype training group compared to The Mulligan-Kinesiotype group was better. But the hamstring range of motion was better in the Mulligan-Kinesiotype group than in the Pilates-Kinesiotype group. In addition, the results showed that there is no significant difference between the waist range of motion of the research groups (P < 0.05). Conclusions: Due to the fact that mulligan and Pilate's exercises together with Kinesiotype have an effect on pain variables, hamstring stiffness and hip rotation, and each of mulligan and Pilate's exercises have different effectiveness. These exercises can be used in combination with Kinesiotype to help women with non-specific chronic back pain.
