Study design: Cross-sectional study. Background: Neuromuscular electrical stimulation (NMES) is an effective tool for stimulating multifidus muscle contractions. Ultrasound imaging (USI) is valid and reliable for quantifying multifidus activity represented by percent thickness change from a resting to contracted state. Thus, USI may be used to help determine optimal NMES intensity. Objectives: To explore NMES intensity effects on multifidus thickening in adults with chronic low back pain (CLBP). Methods: Sixty patients with CLBP participated. L4/5 multifidus ultrasound images were obtained and percent thickness change from a resting to a contracted state was determined at baseline with a limb lift and during NMES application. During NMES, the examiner recorded the intensity, in milliampere, when the multifidus first started to thicken as observed with USI. The examiner also recorded the NMES intensity that resulted in no further multifidus thickening (ie, high-tolerance group) or, in cases where maximal thickening was not observed, the NMES intensity of the submaximal contraction (ie, low-tolerance group). Differences between participants with high versus low NMES tolerance were evaluated. Results: During NMES, the multifidus began thickening at a higher intensity for the high-tolerance group (n = 39), that is, 34 mA, compared with the low-tolerance group (n = 21), that is, 32 mA ( P = .001). A greater mean intensity in the high-tolerance group, that is, 62 mA, as compared to 45 mA in the low-tolerance group, resulted in a larger percent thickness change, that is, 30.89% compared to 20.60%, respectively ( P < .001). Conclusions: Results provide clinicians with NMES intensity targets to facilitate multifidus muscle thickening, which provides insight into muscle activity.

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.

Recent studies show that vitamin D deficiency may be responsible for muscle atrophy. The purpose of this study was to investigate markers of muscle atrophy, signalling proteins, and mitochondrial capacity in patients with chronic low back pain with a focus on gender and serum vitamin D level. The study involved patients with chronic low back pain (LBP) qualified for posterior lumbar interbody fusion (PLIF). Patients were divided into three groups: supplemented (SUPL) with vitamin D (3200 IU/day for 5 weeks), placebo with normal levels of vitamin D (SUF), and the placebo group with vitamin D deficiency (DEF). The marker of muscle atrophy including atrogin-1 and protein content for IGF-1, Akt, FOXO3a, PGC-1α, and citrate synthase (CS) activity were determined in collected multifidus muscle. In the paraspinal muscle, IGF-1 levels were higher in the SUF group as compared to both the SUPL and DEF groups (p<0.05). In the SUPL group, we found significantly increased protein content for pAkt (p<0.05) and decreased level of FOXO3a (p<0.05). Atrogin-1 content was significantly different between men and women (p<0.05). The protein content of PGC-1α was significantly higher in the SUF group as compared to the DEF group (p<0.05). CS activity in the paraspinal muscle was higher in the SUPL group than in the DEF group (p<0.05). Our results suggest that vitamin D deficiency is associated with elevated oxidative stress, muscle atrophy, and reduced mitochondrial function in the multifidus muscle. Therefore, vitamin D-deficient LBP patients might have reduced possibilities on early and effective rehabilitation after PLIF surgery.

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.
