This study aimed to systematically review studies conducted on the application of sonoelastography (SE) to evaluate lumbopelvic muscle stiffness in patients with low back pain (LBP). All relevant articles were retrieved from the available electronic databases, including PubMed, Web of Science, Scopus, EMBASE, Cochrane library, and CINAHL, using the keywords “Sonoelastographyâ€, “Elasticity Imaging Techniqueâ€, “Muscle Stiffnessâ€, “Modulus Elasticityâ€, “Low Back Painâ€. After initial searches, studies that met the inclusion criteria (i.e., published in English and sonoelastography were used to assess lumbopelvic muscle stiffness in both patients with LBP and healthy individuals) were enrolled. Also, any animal research, abstract of the seminar and/or conference, and/or non-English-language article were excluded. The quality of the studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. In total, eight relevant studies were selected for review. Three studies were considered to have excellent quality, and five were considered fair quality using the PEDro scale. All reviewed studies have reported that SE can be considered a non-invasive method for quantifying changes in lumbopelvic muscle stiffness. Muscle stiffness was significantly higher in LBP patients compared to healthy persons, as well as across subgroups of LBP patients in various test postures (PË‚0.05). Only one study was conducted on the reliability of SE in healthy individuals, while another examined the validity of SE imaging. The results of the present systematic review indicated that SE imaging is a reliable and valid tool to identify muscle changes that occur in patients with LBP and evaluate the effects of rehabilitation treatment.

This study aimed to estimate the within-day and between-day reliabilities of sonoelastography to measurethe strain ratios of lumbopelvic muscles, including multifidus (MF), piriformis (P), quadratus lumborum (QL), and gluteusmedius (GM), in a resting position by the sonoelastography device in both patients with unilateral discogenic lumbarpain and healthy individuals. Failthe treatment of deep infection of peri-articular fracture fixation. First of all, the participants (n=25) were enrolled in this study, including patients (n=15) and healthy subjects(n=10). In the first session, an examiner estimated the strain ratio of lumbopelvic muscle three times by sonoelastography.The last session was held at a one-week interval. The collected data were analyzed using an intraclass correlationcoefficient (ICC) and a standard error of measurement. The ICC calculated for MF, P, QL, and GM measurements indicated good to excellent reliabilities in bothhealthy and patient groups for within- and between-intra-examiner reliabilities, which were obtained at 0.94-0.91 and0.86-0.86, 0.87-0.89 and 0.82-0.82, 0.88-0.86 and 0.86-0.86, 0.88-0.84 and 0.84-0.84, respectively. Furthermore, thestandard errors of intra-examiner reliability for MF, P, QL, and GM strain ratio measurements in both healthy andsubject groups were estimated at the ranges of 0.52-0.51 and 0.64-0.65, 0.60-0.62 and 0.77-0.78, 0.23-0.25 and 0.25-0.25, 0.25-026 and 0.30-0.35, respectively. The results revealed that sonoelastography seemed to be a reliable instrument to measure MF, P, QL,and GM muscle strain ratios in healthy subjects and patients with unilateral lumbar radicular pain. However, furtherstudies are recommended to support the findings of the present study in other patients.Level of evidence: III
