Background: It has been shown that five deficits of the proprioceptive system and poor motor skills are associated with chronic low back pain (CLBP). However, the exact mechanism is unknown. The objectives of this study were to assess the dynamic postural balance behavior of CLBP patients, as well as the effects of a specific exercise therapy for the treatment of CLBP and related postural imbalances. Methods: Sixteen females with CLBP and 30 healthy females all between 20 and 40 years of age, of similar height and weight, voluntarily participated in this study. Patients underwent a three-month therapeutic exercise program. The disability and back pain of the patients were measured using the Oswestry and Quebec questionnaires, respectively. A dynamic stability platform system (Biodex) was used to evaluate the postural imbalances in both groups. All measurements of the experimental group were repeated after the therapy. Results: Overall deviation of center of gravity (COG) from COBOS in patients and controls were 3 (±0.3) and 1.3 (±0.2), respectively. Thus, postural imbalances were 2.3 times greater in the patients than those of the controls. After the treatment, the disability and pain of the patients were diminished by 53% and 58%, respectively. Furthermore, with the improvement of the patients COG deviation, both groups had similar posture. Conclusions: The postural orientation of CLBP patients was significantly improved by the therapeutic exercise program. The applied exercise therapy significantly reduced both the pain and the disability of the patients. Based on these conclusions, we recommend that postural correction be included in regular therapeutic exercise programs.
