Effect of motor control exercises combined with self-compassion based on mindfulness training on pain, disability, psychological factors and lumbopelvic kinematic during lifting in patients with chronic nonspecific low back pain.

The effect of motor control exercise combined with self-compassion based on mindfulness training on pain, disability. psychological factors, and kinematic variables of the lumbopelvic in patients with non-specific chronic low back pain.

A controlled clinical trial with parallel groups, single-blind, randomized, on 99 patients, using the instructions available on the website (http://randomizer.org) for randomization.

Assessments will be conducted 2 weeks before and after the intervention in Javad Mofavaghian's Clinical Movement Analysis Laboratory. The protocol will be implemented at the Dofika Health Center. In this study, patients are unaware of the randomization process.

The inclusion criteria: Persian-native female and male, primary complaint of low back pain (more than 3 months, experienced between L1 and the gluteal fold without pathoanatomical cause) confirmed by an orthopedic specialist; The exclusion criteria: previous spinal surgery and neurological signs, specific spinal pathology and Conditions that may be uncontrolled for self-compassion meditation (psychosis, major depression or anxiety), pregnancy.

Group 1, Will receive motor control exercise 3 times a week (for 8 weeks). Group 2, Will receive motor control exercise (3 times a week) along with mindfulness-based self-compassion training (1 time a week) for 8 weeks.

Pain; disability; catastrophizing pain; fear avoidance beliefs; fear of movement; angular velocity of the lumbo-pelvic during lifting; range of motion (ROM) lumbar flexion relative to the hip during lifting; ROM lumbar flexion relative to the pelvic during lifting; ROM pelvic relative to the hip during lifting.

Following the baseline examination, by using the method on the website http://randomizer.org/ (Social Psychology Network, Connecticut, USA), participants are randomly assigned into the two experimental groups (motor control_ self-compassion and motor control) and control group. This site uses the random. Math method in the programming language, JavaScript is used as the main method for generating random numbers. The allocation concealment is done using a computer-generated block randomization table, where the number 1 will be defined for the motor control training group with self-compassion training, the number 2 for the motor control training group, and the number 3 for the control group. Then the random number sequence will be placed in opaque and sealed envelopes. Also, the treatment will be continued by the researcher according to the group assignment. Finally, the results will be evaluated before the interventions and eight weeks after the interventions.

In this study, the patients was blind to the process of randomization and assignment of individuals into experimental and control groups. During the intervention, participants will only be familiar with the members of their own therapy group. Each group will receive the treatment at different times to prevent contact between participants from the two groups.
