Characterization of the Muscle Electrical Properties in Low Back Pain Patients by Electrical Impedance Myography

Abstract BackgroundNon-specific chronic low back pain (NSCLBP) is a multifactor disorder with high prevalence rate of people all around the world. Lumbar paraspinal muscle (LPM) plays an important role of spine stabilization. However, the electrical properties of LPM in the patients were unclear. Aim to explore the electrical properties of bilateral LPM between patients with NSCLBP and healthy controls (HC), the study was designed to applied electrical impedance myography (EIM) technique to measure the LPM.MethodsA total of thirty participates (15 in NSCLBP group, 15 in HC group) were instructed to have each side of LPM measured at the rest state and the maximum volunteer contraction (MVC) state. Then measured the EIM parameters of LPM at L4/5 level by a multi-frequency device. Each measurement repeated three times. The EIM parameters at 50 kHz, 100 kHz, 200 kHz current frequencies were enrolled into the statistical analysis.ResultsAt the three current frequencies, parameters in the right side of LPM had not significantly difference from the left (P>0.05, respectively). Resistance (R) of LPM in NSCLBP group was larger than that in HC group (P<0.05, respectively), phase angle (PA) in NSCLBP group was smaller than that in HC group (P<0.05, respectively) and there was no difference of the reactance value between the two groups (P>0.05, respectively). At 50 kHz, relationships between the EIM parameters and geometric parameters of LPM were not significant in NSCLBP group or HC group (P>0.05, respectively).ConclusionThe electrical properties of bilateral LPM in young adults with NSCLBP were different from those of healthy individuals regardless of any current frequency. The ultrasound parameters of LPM, however, showed no significant difference between young patients with NSCLBP and healthy participants. EIM measurement might be more sensitive than rehabilitative ultrasound for NSCLBP in young adults.Trial registrationThe Chinese Clinical trial registration number: ChiCTR2100043113.

Background and Objectives: Musculoskeletal dysfunction can induce several types of chronic pain syndromes. It is of particular interest to elucidate the pathomechanism of different forms of chronic pain. It is possible that patients who have developed chronic widespread pain (CWP) may endure different pathomechanisms as compared to those who suffer from local pain (osteoarthritis, OA) and regional pain (chronic low back pain, cLBP), especially with regard to pain regulation and its related biomediators. The aim of this study was to determine the differences in pathomechanisms among these patients by measuring pain-related biomediators, particularly brain-derived neurotrophic factor (BDNF). Additionally, subpopulations of immune cells were determined in parallel. Materials and Methods: Patients and healthy subjects (HSs) were recruited (age and gender-matched). BDNF was measured from serum samples of patients and HSs and the data of body composition parameters were recorded. Additionally, both patients and HSs were asked to fill in questionnaires related to pain intensity, anxiety, and depression. Results: Our results highlight that the levels of both free and total BDNF are significantly lower in pain patients compared to HSs, with p values of 0.041 and 0.024, respectively. The number of CD3− CD56bright natural killer (NK) cells shows significant differences between the groups. Comparing all chronic pain patients with HSs reveals a significantly lower number of CD4+ CD8+ T cells (p = 0.031), CD3− CD56bright NK cells (p = 0.049) and CD20+ CD3− cells (p = 0.007). Conclusions: To conclude, it seems that a general conformity between the pathomechanisms of different chronic pain diseases exists, although there are unique findings only in specific chronic pain patients.
