Background: The excessive anterior pelvis tilt in the sagittal plane is one of the important reason for postural disorders. To create a new method of measurement for pelvis title will be bring the additional information. Kendall and McCreary published in 2005 the data of the pelvis position in adults using the Digital Pelvic Inclinometer. In accessible literature there is not any information about its application in children.
Purpose: The purpose of thе study was to investigate the reliability of a digital pelvic inclinometer for measuring the pelvic tilt in the sagittal plane in children.
Methods: The examination involved 132 children (62 girls and 70 boys) with average age 8, 7 (from 7 to 9) years from the beginning classes (from I to III classes) at School Iordan Iovkov Sofia during the period May September 2016. The abnormality of the pelvis tilt in the sagittal plane was identified by observing the level of the anterior and posterior iliac spines (ASIS and PSIS). If the PSIS is higher then the ASIS bilateral was indicated as an anterior pelvis tilt. The Digital Pelvic Inclinometer (DPI) was applied in 115 children of measuring left and rigth pelvic inclination and therefore torsion. The DPI developed by Sub-4 Technologies, , is a precision measuring device used to quantify innominate bone inclination. Data is captured by the DPI via a tiny three-axis accelerometer attached to a small electronics board. The accelerometer measures the static acceleration of gravity in the three directions. The electronics use this data to calculate the angle of tilt and this data is shown in numerical form on the LCD.
Results: Preliminary descriptive statistics analysis revealed that data was normally distributed (skew and kurt indexes were used) and the groups variances were not differed statistically significant (Levenes test was used). In accordance with these findings for testing the statistical significance of differences between groups t-test for independent samples was used.
Children with indicated asymmetry of the ASIS and PSIS were 51 (44,35%) from 115 totally tested. Their mean value of the inclination on left side was 11,30о±5,12о versus 10,23о ±4,49 о in group of children with the equal level. The difference d=1,07о was not significant (t=1,20, p=0.234). The mean inclination on the right side of the group with asymmetry of the levels was 11,14о ±4,35о toward 10,38о ±4,01 о of the other group. The difference d=0,77о was not significant (t= 0,98, p=0.328). Regarding the pelvis torsion the mean value of the children with asymmetry of the ASIS and PSIS was 2,87о ±2,08о toward 2,70о ±1,83о of the group with symmetry. The difference d=0,17о was not significant (t= 0,46, p=0.645).
Conclusion(s): The Digital Pelvic Inclinometer is portable and applicable device for measuring the pelvis inclination in children. The lack of the significant differences between children with an equal level and an asymmetry of the ASIS and PSIS determined the problem as functional.
Implications: Identify in time the abnormality of the pelvis tilt in children will be prevent the progression of the musculoskeletal dysfunction and low back pain.
