Subjects are recruited from the attendees of the multidisciplinary low back pain rehabilitation group before it takes place in University Hospital of Oulu at Physical and Rehabilitation Medicine (PRM) unit. Subjects were invited to participate by letter 2 weeks before the beginning of the rehabilitation. Subjects to rehabilitation are picked by doctor at PRM unit. The volunteered subjects are invited to the briefing of the study and those who are willing to participate, they filled in several questionnaires about pain, participation, disability and mood. After that the subjects are measured at baseline measurement. Subjects are randomized into the five groups. After the 3 months treatment and training the follow-up measurements are performed. Same questionnaires are filled in at that point as well. At 6 and 12 months the follow-up questionnaires (same as before) are sent to subjects.

The volunteered subjects are invited to the briefing of the study and those who are willing to participate, they filled in several questionnaires about pain, participation, disability and mood. After that the subjects are measured at baseline measurement. Subjects are randomized into the five groups: 1) control group, 2) fascial manipulation (FM) and movement control exercises (MCE), 3) sham-FM and MCE, 4) FM and sham-MCE and 5) sham-FM and sham-MCE. Physical therapists who perform treatments (FM), prescribing MCE and performing the measurements are blinded to each other. Physical therapist who is performing measurements is also blinded for the baseline measurements. There and 4 treatments of sham-FM, 4-5 treatments of FM, 4 treatments of sham-MCE and 4-6 treatments of MCE. Control group will receive only university hospital rehabilitation and will participate into the baseline and follow-up measurements. After the 3 months treatment and training the follow-up measurements are performed. Same questionnaires are filled in as at baseline. At 6 and 12 months the follow-up questionnaires (same as before) are sent to subjects.
