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.

Transversus Abdominis Muscle

Research background and hypothesis. Transversus abdominis muscle experiences extraordinary overstretching during gestation period and thus the ability of this muscle to stabilize spine decreases. These changes can cause chronic low back pain during pregnancy and after delivery. In order to solve this problem it is essential to apply proper and effective treatment methods. Hypothesis: physical therapy exercises are more effective than maternity support garment in low back pain treatment and core stability during pregnancy and after delivery.Research aim was to evaluate the influence of physical therapy and maternity support garment on spinal stability and low back pain during pregnancy and after delivery.Research methods. Study sample comprised 40 pregnant women. The assessments were made twice: at 28–35 weeks of gestation and 8–9 weeks after delivery. The low back pain was evaluated using SAS, core stability and transversus abdominis muscle activation were objectively tested using special device stabilizer and the presence of diastasis recti was tested as well. Research results. Physiotherapy is 42.4% more effective than maternity support garment in low back pain control during pregnancy and after delivery (p < 0.05). The best results of transversus abdominis muscle activation were observed in physiotherapy group with maternity support garment whereas participants without physiotherapy could not properly activate this muscle. The diastasis recti after delivery occurred only in control group, and in the group with maternity support garment it occurred 36.7% less frequently than in the group where women did not use this garment.Discussion and conclusions. 1. Perceived low back pain after delivery was less expressed in women wearing maternity support garment both among women attending and not attending physiotherapy exercises. Nevertheless, physical therapy was more effective in reducing low back pain than maternity support garment during pregnancy and after delivery. 2. Core stability after delivery improved among women attending physical therapy exercises, but in case of maternity support garment it improved better. In contrast, in case of not attending physiotherapy the spinal stability after delivery improved only for women wearing maternity support garment. 3. Core stability during pregnancy and after delivery was better among women attending physical therapy but not wearing maternity support garment compared to women not attending physical therapy but wearing maternity support garment. 4. Physical therapy and maternity support garment improves core stability during pregnancy and has a positive effect on activity of rectus abdominis muscles following delivery.Keywords: obstetrics, transversus abdominis muscle, exercises.

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.
