An independent person performed the allocation via sealed, opaque envelopes numbered consequently to ensure the allocation concealment, Blinding description: The assessor and participants were blind to group assignment. While the data analysis was blindly conducted, due to the nature of the intervention (PT, LSO) in both groups, the blinding of the participants and outcome assessor during the test procedure was impossible and it didn't take place. N/A Chronic non-specific low back pain. Intervention 1: Intervention group will receive physical therapy (exercises and electrotherapy) as well as a semirigid lumbosacral orthosis for 6 weeks, 8 hour a day. Intervention 2: The control subjects will receive physical therapy (exercises and electrotherapy) for 6 weeks. Yes - There is a plan to make this available What will be shared: Individual Participant Data collected for the primary and secondary outcome measures will be shared after de-identification. When: If there is a request from researchers, the data will become available after paper publication. To whom: The data will be available for researchers working at the academic institutions. Conditions: More analyses on the data should be performed under supervision of the researchers of this study. Where to obtain: The data would be available through email: ma.hekmat@yahoo.com per requests received from academic researchers. How to obtain: Whenever a request is received, first the researcher should be identified. Second, the aims of the study should be clarified. Further, all ethics related to recruitment of the subjects should be passed. The process will be clarified through email by details. Comments:
