“…13 Chan et al found smaller multifidus cross-sectional area in chronic LBP patients than that in controls using B mode ultrasound. 14 Fortin et al suggested that paraspinal muscles are smaller in patients with chronic LBP than in control patients and on the symptomatic side of patients with chronic unilateral LBP. Rostami et al compared cross sectional area of multifidus muscle in cyclists with and without low back pain.…”

“…Pain alters the magnitude of activation of deep MF during certain types of activity 51. Ultrasound imaging evidence of reduced neural drive in back pain patients includes reduced muscle thickness changes with contraction 52, 53, 54, 55, reduced ability to cause a muscle thickness change on command 56, and altered contraction patterns with changes in posture 57.…”

ObjectivesChronic low back pain (CLBP) is the most prevalent of the painful musculoskeletal conditions. CLBP is a heterogeneous condition with many causes and diagnoses, but there are few established therapies with strong evidence of effectiveness (or cost effectiveness). CLBP for which it is not possible to identify any specific cause is often referred to as non‐specific chronic LBP (NSCLBP). One type of NSCLBP is continuing and recurrent primarily nociceptive CLBP due to vertebral joint overload subsequent to functional instability of the lumbar spine. This condition may occur due to disruption of the motor control system to the key stabilizing muscles in the lumbar spine, particularly the lumbar multifidus muscle (MF).MethodsThis review presents the evidence for MF involvement in CLBP, mechanisms of action of disruption of control of the MF, and options for restoring control of the MF as a treatment for NSCLBP.ResultsImaging assessment of motor control dysfunction of the MF in individual patients is fraught with difficulty. MRI or ultrasound imaging techniques, while reliable, have limited diagnostic or predictive utility. For some patients, restoration of motor control to the MF with specific exercises can be effective, but population results are not persuasive since most patients are unable to voluntarily contract the MF and may be inhibited from doing so due to arthrogenic muscle inhibition.ConclusionsTargeting MF control with restorative neurostimulation promises a new treatment option.

“…Longitudinal measurements during therapeutic interventions may also guide treatment duration or facilitate decisions to alter the therapeutic intervention. With its real-time ability to differentiate between normal and abnormal muscle properties, ultrasound elastography shows promise as a clinical tool to aid in diagnosing muscle abnormalities (12–14), predicting muscle response to treatment (15), and monitoring muscle responses to therapeutic interventions (16,17). The goals of this review are to introduce current ultrasound elastography techniques being used in the study of muscle properties; to outline current research implications for their use in rehabilitation; and to discuss future directions for research on, and potential clinical applications of, ultrasound elastography.…”

The use of brightness-mode ultrasound and Doppler ultrasound in physical medicine and rehabilitation has increased dramatically. The continuing evolution of ultrasound technology has also produced ultrasound elastography, a cutting-edge technology that can directly measure the mechanical properties of tissue, including muscle stiffness. Its real-time and direct measurements of muscle stiffness can aid the diagnosis and rehabilitation of acute musculoskeletal injuries and chronic myofascial pain. It can also help monitor outcomes of interventions affecting muscle in neuromuscular and musculoskeletal diseases, and it can better inform the functional prognosis. This technology has implications for even broader use of ultrasound in physical medicine and rehabilitation practice, but more knowledge about its uses and limitations is essential to its appropriate clinical implementation. In this review, we describe different ultrasound elastography techniques for studying muscle stiffness, including strain elastography, acoustic radiation force impulse imaging, and shear-wave elastography. We discuss the basic principles of these techniques, including the strengths and limitations of their measurement capabilities. We review the current muscle research, discuss physiatric clinical applications of these techniques, and note directions for future research.
