Methods and Materials: Thirty participants were randomly placed into either a WBV group or a spinal stabilization group at Shahid Beheshti University of Medical Sciences, Tehran, Iran, in 2013. The dependent variables manipulated included the abdominal and spinal muscular endurance, assessed prior to, midway through, and after two weeks and the WBV or spinal stabilization intervention program implemented using stabilizer pressure biofeedback unit and Biering Sorensen test. Results: Changes in transverse abdominal and internal oblique muscle endurance in prone position were statistically significant among the participants in both groups (P<0.05). However, changes in transverse abdominal muscle endurance in supine position and multifidus muscle endurance were not observed to be statistically significant in both groups. In addition, inter-group analysis showed that except for the percentage of changes of multifidus muscle endurance, the vibration group demonstrated significant improvement over the non-vibration group. Conclusion: As no significant difference was observed between the two treatment methods, none of treatment methods was more effective comparatively in terms of improving mid-term trunk muscle endurance.

Introduction The financial costs and disability caused by low back pain (LBP) are among growing clinical and socioeconomic problems (1). Although 5%-10% of patients suffer from chronic pain and disability, higher rates have been reported for chronic back pain as 42%-75% and recurrence of back pain episodes (24%-84%) (2). After developing LBP, patients often remain sedentary because of the fear of the pain caused by movement. Such behavior is harmful in particular as the decreased amusement activity results in deconditioning (3). Fatigue caused by low endurance in trunk muscles may affect the ability of people with LBP in responding to the demands of an unexpected load. After repetitive loadings, fatigue may also lead to control and precision loss; prejudice the individual to develop the LBP. Therefore, trunk muscle endurance training has been recommended to elevate fatigue threshold and improve performance, and consequently, to reduce lumbar spine disability (4). Trunk muscles mainly function as support to the vertebrae (5). Lower back extensor muscles play an important role in dynamically controlling the moving segments (5). While each of the local paraspinal muscles promote spinal stability, the multifidus alone is the cause of more than two-thirds of the stiffness with sagittal plane movements when the local paraspinal muscles are contracted (4). The synergistic contractions of the multifidus and deep abdominal muscles function as a dynamic corset for the lumbar vertebrae (3). These muscles increase spinal stiffness via elevated intra-abdominal pressure because of tensioning the lumbar spine, generating a posterior shear force against the lumbar spine, decreasing the compliance of abdominal contents, or indirectly increasing the thoracolumbar fascia tension (6). Intra-abdominal pressure impresses spinal stability by producing an extensor moment and applying force down on the pelvic floor as well as up on the diaphragm (7). Poor spinal and abdominal muscle control can be seen among individuals with chronic LBP (8-10). Supporting such
