Nonlinear Parameters

The characteristics of postural sway were assessed in quiet standing under three different postural task conditions in 14 patients with nonspecific chronic low back pain and 12 healthy subjects using linear and nonlinear center of pressure parameters. The linear parameters consisted of area, the mean total velocity, sway amplitude, the SD of velocity, and the phase plane portrait. The nonlinear parameters included the Lyapunov exponent, sample entropy, and the correlation dimension. The results showed that the amount of postural sway was higher in the patients with low back pain compared with the healthy subjects. Assessing the nonlinear parameters of the center of pressure showed a lower sample entropy and a higher correlation dimension in the patients with low back pain compared with the healthy subjects. The results of this study demonstrate the greater regularity and higher dimensionality of the center of pressure fluctuations in patients with nonspecific chronic low back pain, which suggests that these patients adopt different postural control strategies to maintain an upright stance.

Abstract Objective This study was to comparison of level of lumbar stability and postural sway in sagittal plane and coronal plane between exercise with ball and sling in the patients with non-specific chronic low back pain (NCLBP). Methodology Twenty participants with NCLBP aged 20 to 55 years were randomly divided into exercise with ball group (BG) and exercise with sling group (SG). Both groups performed 8 exercise sessions; two times per week for four weeks. The visual analog scale (VAS), modified oswestry disability questionnaire (MODQ), modified isometric stability test (MIST) were used to measure at baseline, week 2 and week 4 after exercise. Moreover, the sway area and sway velocity were evaluated at before and after training. Both group performed exercise 15 repetitions per set for 3 sets with 1-minute resting between set. A repeated two-way ANOVA was used to analyze the difference variables between both groups. Results The results showed significant difference between pre and post treatment of pain intensity, functional disability, MIST and postural sway in both groups (p<.001). When compared between both groups, the reduction in all parameters for the BG group was significantly higher than the SG group (p<.05). Moreover, the findings represented that the postural sway in both sagittal and coronal plane showed no significant difference between both groups after complete treatment. Conclusion The core stabilization exercise with ball and with sling can provided reduction of pain and functional disability. Moreover, the BG group is more effective for decreasing of pain, disability and improving of lumbar stability may described by greater perturbation of the ball. During perform exercise on ball bring to unstable and increasing of neuromuscular control. These results can applied to clinical practice for choosing the appropriate exercise program in the patients with NCLBP.

Background. Chronic low back pain (LBP) leads to long-term physical and psychological problems and may result in acute deterioration of the pain. It is hypothesized that size changes in selected limb and pelvis muscles during contracting movements are different between healthy individuals and LBP patients. Materials and methods. A case-control study including two groups of 30 female participants with and without LBP symptoms was designed. Participants were 20-45 years old (36.7±6.7, healthy subjects; 34.6±6.2 LBP subjects). Ultrasonography was used to estimate the thicknesses of the quadratus lumborum (QL), gluteus medius (GMed), transversus abdominis (TrA) and lumbar multifidus (MF). Thickness changes of the muscles in a submaximal contracting position compared to the rest position were measured. Statistical analysis included an independent t-test to determine the significance of differences, and the Kolmogrov-Smirnov two-sample test to evaluate the normality and reliability. Results. All muscles increased their thickness during contractions. The average increase in LBP subjects was lower than in the healthy subjects. The smaller increase in the muscle thickness of GMed in the LBP group may suggest a weakness because of imbalance in the GMed muscle of LBP patients. Conclusions. 1. Ultrasonography of local and global muscles is an appropriate device for clinical diagnosis of LBP. 2. Strengthening TrA, MF, and GMed muscles for pain prevention is effective in the prevention and treatment of LBP.
