TLDR
Reliability was higher in the lumbar multifidus muscles than the erector spinae muscles, slightly higher during contraction than during rest, and substantially improved by using the mean of 3 measurements.About:

Reliability of rehabilitative ultrasound imaging of the transversus abdominis and lumbar multifidus musculature
TL;DR: In this article, the intraexaminer and interexaminer reliability of rehabilitation ultrasound imaging (RUSI) in obtaining thickness measurements of the transversus abdominis (TrA) and lumbar multifidus muscles at rest and during contractions was evaluated.
Behaviour of the lumbar multifidus during lower extremity movements in people with recurrent low back pain during symptom remission
TL;DR: In this article, the authors used ultrasound imaging to measure lumbar multifidus (LM) thickness change parasagitally at the L4-5 and L5-S1 levels in people with recurrent low back pain (LBP) during symptom remission and in healthy participants, during the following lower extremity movements: (1) active straight leg raise (ASLR), (2) crook-lying active leg raise, and (3) prone straight leg raises (PSLR).

Reliability of tensiomyography and myotonometry in detecting mechanical and contractile characteristics of the lumbar erector spinae in healthy volunteers
TL;DR: MMT was found to be more reliable on repeated testing than the two other TMG parameters Dm and Tc, and Vc demonstrated to be the most reliable and repeatable TMG parameter.

Shear wave elastography investigation of multifidus stiffness in individuals with low back pain
TL;DR: A differentiation in passive muscular stiffness between SM and DM is supported and evidence for an alteration in muscular stiffness at rest in individuals with LBP is provided to reflect a deficit in activation of the multifidus.

Lumbar muscle stiffness is different in individuals with low back pain than asymptomatic controls and is associated with pain and disability, but not common physical examination findings.

TL;DR: Resting lumbar muscle stiffness is greater in individuals with LBP than asymptomatic controls and is associated with self-reported pain and disability, but not physical exam findings.

CT imaging of trunk muscles in chronic low back pain patients and healthy control subjects.
TL;DR: A comparative study between unoperated CLBP patients and matched control subjects with regard to muscle cross-sectional area (CSA) and the amount of fat deposits at different levels showed that only the CSA of the multifidus and only at the lowest level was found to be statistically smaller in LBP patients.

Validation of shear wave elastography in skeletal muscle.
TL;DR: This study provides the necessary first step for additional studies that can evaluate the distribution of stiffness throughout muscle, and combines traditional materials testing techniques with SWE measurements to show increased stiffness measures with increasing tensile load.

Evidence of altered lumbopelvic muscle recruitment in the presence of sacroiliac joint pain.
TL;DR: In this article, a cross-sectional study was conducted to determine whether muscle activation of the supporting leg was different between control subjects and subjects with sacroiliac joint pain during hip flexion in standing.

Epidemiology of Low Back Pain in Adults
TL;DR: In this article, a comprehensive review is undertaken to assess the increasing prevalence of low back pain and the influence of comorbid factors, along with the increasing health-care costs.
