Chronic low back pain is one of the most common musculoskeletal problems. This disease, in addition to causing pain and disability affects the gait parameters in patients. The purpose of this study was to investigate the effect of aquatic exercises therapy on the severity of pain, disability and Spatiotemporal parameters and kinetic of gait in women with chronic low back pain. Twenty-four women with chronic low back pain (with a mean age of 26.6 years) participated in this study. The exercise protocol was conducted in water for 8 weeks. The severity of pain and disability were measured by Quebec and Oswestry questionnaires respectively. gait parameters were evaluated using a foot pressure device. Aquatic exercises therapy significantly decreased pain and disability severity and significantly improved gait parameters in the experimental group (p≤0.05). Fore there more, the significant difference between the variables in the post-test was obtained between experimental and control groups (p≤0.05). No significant difference was observed between the pre-test and post-test comparisons in the control group (p≥0.05). Regarding the reduction of pain and disability and improvement of gait parameters after eight weeks’ intervention in experimental group, the use of this protocol is recommended to improve patients with chronic low back pain as a new method.
 

Considering the prevalence of pain and disability in the knee joint, the present study investigated the effect of core stability training with improving knee joint proprioception on balance, pain and functional disability of women with chronic knee pain. 20 women aged 30 to 50 with chronic knee pain were placed in two experimental and control groups. To measure static and dynamic balance, pain and functional disability, the stork balance tests, Y, VAS and VOMACK questionnaire were used, respectively. Exercises were followed for eight weeks in the experimental group. To evaluate the research hypotheses, the analysis of variance test with repeated measurements was used in spss software version 24. The results showed that before the exercise protocol, there was no significant difference between the control and experimental groups in any of the measured variables. While the eight-week training protocol caused a significant difference in static and dynamic balance, functional disability and pain between the control and experimental groups. Therefore, core stability training with improving knee joint proprioception increase balance in people with chronic knee pain, which can reduce the risk of falling in these people and improve the quality of life by improving pain and functional disability.
