Objectives: To investigate the effectiveness of a controlled accelerated short-term lumbar stabilizing exercises on postural indices and limit of stability in patients with non specific chronic low back pain. Materials & Methods: A sample of convenience of 20 patients with nonspecific chronic low back pain participates in this pretest – posttest study. Postural control indices including Overall stability index (OSI), Anterior-posterior stability index (APSI), Mediolateral stability index (MLSI), time and functional performance of limit of stability were recorded before and after stability training. All data were analyzed using paired t-test. Results: The results of this study showed significant difference all variables except OSI and APSI in double leg eyes open situation. As well, in single leg standing position OSI and APSI with eyes open were significant (p<0/05). Also, time and functional performance of limit of stability were significant before and after treatment. (p<0/001) Conclusions: Controlled accelerated short-term lumbar stabilizing exercises during 10 sessions may improve postural balance and limit of stability in males with non specific chronic low back pain.
