Muscle strength in the anti-graviational and dorsal extensor muscles of children with scoliosis.
ABSTRACT Background. A review of the literature indicates that exercises strengthening the dorsal extensor muscles occupy a significant place in the program of posture reeducation. These exercises are usually performed in positions other than vertical. It has not been proven, however, that the strength of these muscles in children with scoliosis is insufficient to hold the spine in an upright position. As a result of evolution, the human being walks upright, against gravity. In normal conditions, then, the strength of the antigravitational muscles would seem to be the most important. The purpose of our research was to investigate the strength of the antigravitational muscles and the long dorsal muscles in a group of children with scoliosis. Material and methods. 51 children were tested in a special stand for the measurement of maximum force in these muscle groups, during isometric contraction for 10 seconds. The examinations were performed using a "MikroFET 2" device in cooperation with a computer and the "Hercules 2000" software. Results. The initial results showed considerable individual differentiation in the strength of the antigravitational and dorsal extensor muscles among the study population. The differentiation was decidedly greater in relation to the antigravitational muscles. With some isolated exceptions the strength of these muscles was greater than the strength of the dorsal extensors. Interestingly, there was no significant correlation with the children's age or the degree of spinal curvature. Conclusions. The strength of the afore-mentioned muscles appears to be of secondary importance for maintaining the correct posture.

ABSTRACT: According to the general definition of scoliosis, it is an abnormal curvature of the spine. Rotation or more accurately twisting of the spine, may lead to a gradual curve, and it is almost always painless. Scoliosis is not a disease, it is a descriptive term. Curvatures of the spine in the frontal plane are present in order to maintain the upper body part in proper balance. However, when there are lateral curvatures of the spine, scoliosis exists as well. People with a family history of spinal deformity are at greater risk for scoliosis development. The early detection is essential. The risk factors for worsening of scoliosis curvatures, except for growth include: gender (scoliosis curvature in girls more often worsens during growth, as one compared to boys), age (when scoliosis appears in the younger child, the greater is the chance that the curvature will get worse), size of the curvature (with the higher degree of curvature, goes the greater probability that it will worsen over time), location (scoliosis curvature in the lower spine are with less opportunities of promotion than those in the upper spine). Unfortunately, scoliosis often becomes evident in the time when children become selfconscious about their bodies (10 to 15 years of age), so that parents and others have even less likelihood to see the problem. Scoliosis can lead to serious health problems, such as severe back pain, difficulty in breathing, physical deformities, and even injuries of lung and heart.Acta Medica Saliniana. 01/2010;
