Abstract Objective To examine the effect of neuromuscular electrical stimulation (NMES) combined with core stabilization exercises (CSE) in patients with chronic low back pain (CLBP). Methods Thirty-six patients (mean age 33.6±12.6 years) with CLBP were randomly assigned to 4 weeks (12 sessions) of NMES group (NMES combined with CSE) (n=18) vs. Control group (sham NMES and CSE) (n=18). After the 4 weeks, same exercises were given as home exercise program without NMES. The outcome measures were Oswestry Disability Index (ODI), Visual Analog Scale (VAS), Nottingham Health Profile (NHP) and ultrasonography. Ultrasonography was used for measuring transversus abdominis (TrA), internal oblique (IO), external oblique (EO) muscles thickness and lumbar multifidus muscle thickness and area. Assessments were performed at baseline and 4th week and eighth week follow-up. Results In both groups, the change of ODI, VAS and NHP values of the first measurement according to the values of the 4th week and the eighth week were found statistically significant (p=0.001; p<0.01). There were no statistically significant differences in ODI, VAS and NHP scores between the 4th week and the eighth week in both groups (p>0.05). None of NMES and control group measurements with US showed a statistically significant increase in the TrA, IO, EO thickness and multifidus thickness and area (p>0.05). Conclusions It was shown that NMES can be tolerated by patients with CLBP, but the addition of simultaneus NMES to CSE had no contribution to the clinical outcome measures.

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.

Direct Vibration

Abstract Background: We used two methods, direct and indirect, to study the application of vibration training. This pilot study aimed to investigate the short-term effect of direct vibration and spinal stabilization exercises on the deep trunk muscles of patients with non-specific chronic low back pain (CLBP). Methods: Sixty-two participants with non-specific CLBP were randomly placed into two groups, one with direct vibration to the trunk muscles, VSE (vibration-plus stabilization exercise) group, and one without, CSE (conventional stabilization exercise) group. The groups underwent twelve sessions of an exercise program for spinal stability. We measured the thickness and activity of the following trunk muscles using ultrasonography and surface electromyography (sEMG): transversus abdominis (TrA), external oblique (EO), internal oblique (IO), rectus abdominis (RA), lumbar multifidus (LM), and lumbar erector spinae (LES). Results: The ultrasonographic examination revealed that the ratio of muscle thickness to muscle contraction and relaxation was increased after training in the TrA and LM muscles of patients in the CSE group, and in the TrA, LM, and IO muscles in the VSE group. We also found that the LM/LES ratio in the CSE group and the IO/RA, TrA/RA, and LM/LES ratios in the VSE group were significantly increased. Using multiple regression analysis, we showed that the improvement of the symptoms was related to increased activity of the deep trunk muscles in the VSE group (p<0.05).Conclusion: The findings suggest that direct vibration on the trunk muscles may increase the activity of contracting deep muscles and be used in addition to the effective enhancement of stabilization exercise in patients with non-specific CLBP.Trial registration: KCT0003858.

Purpose. Pain catastrophizing may contribute to the altered trunk muscle activity in patients with nonspecific chronic low back pain (NSCLBP). It is unclear if pain catastrophizing influences static postural control in patients with NSCLBP. This study aimed to investigate the relationship between pain catastrophizing and static postural control in NSCLBP patients. Methods. Sixty-eight participants with NSCLBP and 40 healthy participants were recruited. Postural control was assessed by the sway area and the sway length of the center of pressure (COP) during balance tests. Pain catastrophizing in participants with NSCLBP was assessed by the Pain Catastrophizing Scale (PCS). Bilateral transversus abdominis (TrA) activation was evaluated by ultrasound imaging-measured percent change in muscle thickness. Associations between COP parameter and PCS/subscales of PCS were examined by multiple linear regression (MLR). Results. Our results observed a larger COP sway area in NSCLBP group under eyes-closed condition p < 0.001 and a lower level of voluntary activation of the bilateral TrA p < 0.001 , compared with the healthy control group. The MLR analyses revealed that the COP area sway under eyes-closed condition was significantly associated with the PCS score/helplessness score of PCS, voluntary activation of the left TrA, and age in participants with NSCLBP (β = 0.222/0.236, 0.341/0.344, and 0.328/0.325; p = 0.045 / 0.033 , 0.002, and 0.004, resp.). Conclusions. Static postural control was associated with pain catastrophizing, voluntary activation of TrA, and age in participants with NSCLBP. This indicated that pain catastrophizing may affect postural control and should be considered when interpreting balance test results and managing NSCLBP.
