“…The results showed that in patients with AIS, the average amplitude of MEP (Motor Evoked Potential) was greater on the convex side of curvature. 49 Domenech, 50 , 51 using transcranial magnetic stimulation, showed that patients with scoliosis have significantly reduced cortico-cortical inhibition on the concave side of curvature. He also provided evidence of incorrect, asymmetrical activation of the contralateral additional motor cortex during motor tasks with upper limb activation in patients with idiopathic scoliosis.…”

The aim of the study was to assess the relationship between erector spinae electromyographic frequency (SEMG) and the location, direction and number of spinal curvatures in children with scoliotic changes. Methods: Analysis comprised 103 (42,21%) children with scoliosis and 141 (57.79%) with scoliotic posture. Body posture and the spine were examined using the Diers formetric III 4D optoelectronic method. Electromyographic analysis was performed using a 14-channel Noraxon TeleMyo DTS apparatus. Results: In girls, the highest mean SEMG frequency of the erector spinae, calculated from 16 measurements, occurred in the case of scoliotic posture (Mean = 73.69 Hz), while in boys, the greatest values were noted for scoliosis (Mean = 79.75 Hz). There was a significant correlation between erector spinae SEMG frequency and curvature location, both in the scoliosis group (p = 0.003) and in the group with scoliotic posture (p = 0.04). There was also a significant correlation between SEMG frequency of the erector spinae and direction of the curvature, both in the scoliosis (p = 0.01) and scoliotic posture groups (p = 0.04), as well as between the erector spinae SEMG frequency and the number of spinal curvatures (scoliosis group: p = 0.03; scoliotic posture group: p = 0.03). Conclusion:The study is of applicative value and fills the gap in research on erector spinae SEMG frequency of in low-grade scoliosis among small children. Our research can also be used in research on the etiology and progression scoliosis. Visible disturbances in the erector spinae SEMG frequency (activity and tension) contribute to the development of curvature and testify to the fact that these changes are the primary cause of idiopathic scoliosis. Scoliosis is merely a symptom, an external expression of CNS dysfunction that is not fully recognised. It is also visible on the SEMG record of postural muscles. Our objective is to contribute to creating a future model record for SEMG of the postural muscles, characteristic for children with scoliosis. Then, based on electromyographic examination, it will be possible to identify initial symptoms of scoliosis and start preventive rehabilitation before irreversible bone changes occur.

Scoliosis is a three dimensional deformity of the spine characterized by rotation of the vertebrae in the transverse plane and curvatures in the frontal and sagittal plane 1. The key radiographical tool for diagnosis is Cobb angle, which is the angle created by lines crossing over the upper limit of the first vertebra in the curve and the lower limit of the lowest and final vertebra in the anterior-posterior radiography. Although this cannot entirely describe all spinal abnormalities , it is easy to calculate and to assess and has become the gold standard for scoliotic diagnosis 2. Deformity is the main clinical sign during the examination, not followed by the presence of pain. The spine may be obviously deviated from the midline ,or this may become apparent only when the patient bends forward (the Adams test) 3. The major curvature may be located at the thoracic, thoracolumbar or lumbar part of the vertebral column and the convexity may point to the left or right side, with compensatory and smaller curvatures above and below. The most common pattern is a thoracic curvature with right convexity with a compensatory left convexity at the lumbar vertebrae 4. Scoliosis is divided, in terms of etiology, into idiopathic (no known cause or disease), congenital (present at birth due to congenital etiological factors), and secondary(where it is caused by another disease) 2. Idiopathic scoliosis consists, moreover, of three sub-categories, according to the age of diagnosis, as infantile (between 0-3 years old), juvenile (between 4-9 years old) and adolescent (age 10 up to maturity) 5. Adolescent idiopathic scoliosis (AIS) has a prevalence rate between 1-3% and is more common in girls during puberty. The number of girls with AIS is two times higher than the number of boys with this disease and the prevalence is eight times higher among girls than boys when the deformation consists of curvatures greater than 30 degrees 6. Research into the etiopathogenesis of idiopathic scoliosis (IS) has spread through the years to multiple areas and a great number of suggestions has been made during the last decades concerning hormones, genetic , metabolic and biomechanical factors. Although a lot of theories have been proposed, none is capable to fully describe the pathophysiology of the disease, underlying the complexity and the multifactorial etiology of the condition. The purpose of this review is to summarize the main concepts of etiology Abstract Scoliosis is a three-dimensional deformity of the spine.

“…Usually, the human body can maintain postural balance through the joint regulation of vision, vestibular sense, proprioception, etc. But scoliosis patients have abnormal postural sensation and vestibular sensations [17] . It is speculated that the imbalance leads to the imbalance of muscles on both sides of the spine, which cannot maintain normal spinal arrangement, thereby causing scoliosis.…”

Objective: To analyze the relationship between lifestyle habits and scoliosis severity in children with idiopathic early-onset scoliosis (IEOS). Method: A total of 208 children with IEOS were enrolled. Lifestyle habits and Cobb’s angles were collected for analysis. Result: Emaciation(p=0.048), lack of sleep (p=0.017), lack of sunlight (p=0.010), lack of fish, shrimp and egg (p=0.029), exercise (p=＜0.001) and postural awareness (p=0.004) were all independent influencing factors of Cobb’s angles among IEOS Children. Conclusion: BMI, sleep, sunlight time, fish, shrimp and egg diet, exercise, and posture awareness were all related to IEOS closely. It should be encouraged to develop children's healthy lifestyle habits.
