“…In addition, asymmetry in paraspinal muscle activities is observed in adolescent idiopathic scoliosis (AIS) [ 4 – 8 ]. Specifically, the angle of spinal curvature significantly correlated with the surface electromyography (sEMG) amplitude of the erector spinae in young school children [ 9 ]. Kwok et al [ 7 ] compared paraspinal muscle activities between female adolescents with and without mild scoliosis (i.e., spinal curve angle less than 20°) by sEMG during habitual standing and sitting postures and found that those with thoracic- or thoracolumbar-type scoliosis had higher average root-mean-square (RMS) sEMG values on the convex side of the affected muscle regions.…”

Adolescent idiopathic scoliosis (AIS) is characterized by uneven shoulders, spinal curvature, and uneven hips, and asymmetry in paraspinal muscle activities is common in AIS. This pilot study was aimed at examining the use of a surface electromyography (sEMG) biofeedback posture training program in adolescents with mild scoliosis ( Cob b ’ s angle < 30 ° ) to attenuate asymmetry in paraspinal muscle activities and control the curve progression. Seven female adolescents (age, 12–14 years) with mild scoliosis ( Cob b ’ s angle < 30 ° ) were recruited. The participants received 30 tailor-made sessions of sEMG biofeedback posture training at a rate of one to two sessions per week for approximately 6 months. The activities of the paraspinal muscles (the trapezius, latissimus dorsi, thoracic erector spinae, and lumbar erector spinae) measured by sEMG during habitual sitting postures and spinal deformity evaluated by 3D ultrasound imaging were compared before and after training. The mean values of the root-mean-square sEMG ratio, an index of symmetry in paraspinal muscle activities of the muscle pairs between the concave and convex sides of the spinal curve, revealed significant asymmetry over the trapezius and lumbar erector spinae before the training (p <0.05). After the training, all seven adolescents achieved relatively more symmetrical paraspinal muscle activities over these two muscle pairs ( p < 0.05 ). In two adolescents, the spinal curvature decreased by 5.7° and 5.6°, respectively, whereas the remaining adolescents showed a minimal curve progression with changes in the spinal curvature controlled under 5°. To conclude, sEMG biofeedback posture training can reduce asymmetry in paraspinal muscle activities and control curve progression in adolescents with mild scoliosis and can potentially be considered an alternative early intervention for muscle reeducation in this cohort.

“…This asymmetry is more prevalent in LBP patients, inducing a unilateral pathological activation of the lumbar musculature [12]. Wilczyński et al found significant correlations between increased ES neuromuscular activity and the Cobb angle of scoliotic postural change [36]. They conclude from their results that idiopathic scoliosis frequently is the consequence of an asymmetrically increased muscle tone of the ES.…”

Background: Spine shape parameters, such as leg length, kyphotic or lordotic angle, are influenced by low back pain. There is also evidence that the thoracolumbar fascia plays a role in such pa-thologies. This study examined the immediate effects of a myofascial release technique (MFR) on the thoracolumbar fascia and of an osteopathic treatment (OMT) on postural parameters in pa-tients with acute low back pain (aLBP). Methods: This study was a single-blind randomized pla-cebo-controlled trial. Seventy-one subjects (43.8 ± 10.5 years) suffering from aLBP were randomly and blinded assigned to three groups to be treated with MFR, OMT or a placebo intervention. Spinal shape parameters (functional leg length discrepancy (fLLD), kyphotic angle, lordotic an-gle) were measured before and after the intervention using video raster stereography. Results: Within the MFR group, fLLD reduced by 5.2 mm, p < 0.001 and kyphotic angle by 8.2 degrees, p < 0.001. Within the OMT group, fLLD reduced by 4.5 mm, p < 0.001 and kyphotic angle by 8.4 °, p = 0.007. Conclusion: MFR and OMT have an influence on fLLD and the kyphotic angle in aLBP patients. The interventions could have a regulating effect on the impaired neuromotor control of the lumbar muscles.
