Abstract
Primary school children are exposed to asymmetric loads that lead to an imbalance of postural muscles and a violation of the body relative symmetry. Mass screening examinations in schools for scoliotic posture and scoliosis are conducted primarily through the Adams test. It has low reproducibility and a high frequency of false negative results. In practice, various methods for diagnosing posture disorders are also used. Some methods are based on the evaluation of postural muscles static endurance, elasticity and proportionality of their functional capabilities. Others are based on a comprehensive assessment of the ability to maintain an upright posture rationally. The third ones are based on the analysis of the tonic vibration and H-reflex of skeletal muscles on both sides of the vertebral column. All the above mentioned methods definitely have diagnostic potential. Therefore it was decided to determine the validity of some common methods for diagnosing posture disorders based on the analysis of their mutual congruence. Based on the results of the experiment, a reliable correlation between the studied parameters was established. It in turn allows us to judge the congruence of the considered diagnostic methods and, accordingly, the high probability of their validity.
Highlights
Posture disorders in children and adolescents are widely known to society
The aim of the study is to determine the validity of some common methods for diagnosing scoliotic posture in primary school children based on the analysis of their mutual congruence
In order to confirm the validity of test tasks that characterize the imbalance of postural muscles in the presence of scoliotic posture, the level of relationship between the studied indicators was assessed by means of the correlation analysis
Summary
Posture disorders in children and adolescents are widely known to society. At the same time it is an underestimated problem. Primary school age is a sensitive period of coordination abilities education It is the age for starting the formation of the need for systematic physical exercise [1]. Prolonged sitting has a negative effect on the activity of the lumbar muscles It leads to a redistribution of load on the passive structures of the vertebral column and, contributes to the aggravation of muscle imbalance. It is a risk factor for posture disorders [2] and the occurrence of pain in the lumbar spine [5]
