Purpose: To compare and quantify with ultrasound imaging (USI) the inter-recti distance (IRD), rectus abdominis (RA), external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), and multifidus thickness and the RA and multifidus cross-sectional area (CSA) between individuals with and without chronic mid-portion Achilles tendinopathy (AT).

Methods: A cross-sectional study. A sample of 143 patients were recruited and divided into two groups: A group comprised of chronic mid-portion AT ( = 71) and B group composed of healthy subjects ( = 72). The IRD, RA, EO, IO, TrAb, and multifidus thickness, as well as RA and multifidus CSA, were measured by USI.

Results: USI measurements for the EO ( = 0.001), IO ( = 0.001), TrAb ( = 0.041) and RA ( = 0.001) thickness were decreased as well as IRD ( = 0.001) and multifidus thickness ( = 0.001) and CSA ( = 0.001) were increased for the tendinopathy group with respect the healthy group. Linear regression prediction models ( = 0.260 - 0.494; < 0.05) for the IRD, RA, EO, and IO thickness ( = 0.494), as well as multifidus CSA and thickness were determined by weight, height, BMI and AT presence.

Conclusions: EO, IO, TrAb, and RA thickness was reduced and IRD, multifidus thickness and CSA were increased in patients with AT.

Objective: The aim of this work is to demonstrate how the chronicity of low back pain can modify the trophism of the paraspinal muscles, by performing an ultrasound and MRI evaluation of the paraspinal muscles in the lumbar spine and correlating it to the time of onset of low back pain.

Materials And Methods: An ultrasound evaluation was carried out in the lumbar area with a 5-17 MHz linear probe of the paraspinal muscles of the lumbar region, compared with the MRI of the lumbar spine, in patients presented to our attention for chronic low back pain (> 6 months), from January 2021 to January 2023. In each patient, two series of images were analyzed, in the coronal and sagittal planes.

Context: Intermittent floor trunk extensions are popular exercises in group fitness programs. The aim of this study was to investigate whether fewer repetitions of longer isometric trunk extension efforts compared with more repetitions of shorter isometric contractions have different acute effects on muscle thickness and activation as well as perceived exertion.

Design: This study followed a cross-sectional design.

Purpose: Fibrosis of muscle spindles (sensory organs) in back muscles induced by intervertebral disc (IVD) degeneration could limit transmission of muscle stretch to the sensory receptor and explain the proprioceptive deficits common in back pain. Exercise reduces back muscles fibrosis. This study investigated whether targeted muscle activation via neurostimulation reverses or resolves muscle spindle fibrosis in a model of IVD injury.

Background: Low back pain (LBP) is one of the most common conditions in the United States. Dysfunctional patterns of the erector spinae (ES) and gluteus medius (GM) muscles often accompany episodes of LBP.

Objectives: To evaluate the intra-rater reliability of rehabilitative ultrasound imaging (RUSI) in obtaining thickness measurements of the ES and GM muscles at rest and during submaximal contraction.
