A new Goniometer cum posture evaluation tool 'Bodygraph' was developed; it consisted of a full-round goniometer and a fixation rod designed to hold it in different positions. The device features a fixation strap that fixes the bodygraph with the body of the patient. The advantage of this novel tool is that it can be used for both goniometry and posture evaluation. The purpose of this study was to test criterion validity and reliability of 'Bodygraph'. Measurements of cervical lateral flexion Range of Motion were taken on the 'Bodygraph' in two different setting for validity and reliability analysis. Fifty eight young healthy subjects (35 males&23 females; mean: age - 23.05 yr. height - 1.64 mtr. BMI - 20.65) participated in criterion validity analysis study and sixty young healthy individuals (36 males&24 females; mean: age - 23.65 yr. height - 1.65 mtr. BMI - 21.45) participated in reliability analysis. Observations for validity study were taken by an anatomist. A radiograph was taken concurrently to serve as the 'gold standard' for criterion validity study. Observations for reliability analysis were taken by three physiotherapists on four occasions. The Pearson product-moment correlation coefficient 'r' value for criterion validity of 'Bodygraph' was found to be 0.74 (p-value 0.000). The Intraclass Correlation Coefficient ICC value for Intratester reliability of 'Bodygraph' ranged from 0.96 to 0.98 (p-value 0.000). ICC value for Intertester reliability of 'Bodygraph' was found from 0.81 to 0.97 (p-value 0.000). The study concluded that the 'Bodygraph' can be considered to be valid and reliable for measurement of Range of Motion of cervical lateral flexion.

Abstract


A new Goniometer cum posture evaluation tool 'Bodygraph' was developed; it consisted of a full-round goniometer and a fixation rod designed to hold it in different positions. The device features a fixation strap that fixes the bodygraph with the body of the patient. The advantage of this novel tool is that it can be used for both goniometry and posture evaluation. The purpose of this study was to test criterion validity and reliability of 'Bodygraph'. Measurements of cervical lateral flexion Range of Motion were taken on the 'Bodygraph' in two different setting for validity and reliability analysis. Fifty eight young healthy subjects (35 males&23 females; mean: age - 23.05 yr. height - 1.64 mtr. BMI - 20.65) participated in criterion validity analysis study and sixty young healthy individuals (36 males&24 females; mean: age - 23.65 yr. height - 1.65 mtr. BMI - 21.45) participated in reliability analysis. Observations for validity study were taken by an anatomist. A radiograph was taken concurrently to serve as the 'gold standard' for criterion validity study. Observations for reliability analysis were taken by three physiotherapists on four occasions. The Pearson product-moment correlation coefficient 'r' value for criterion validity of 'Bodygraph' was found to be 0.74 (p-value 0.000). The Intraclass Correlation Coefficient ICC value for Intratester reliability of 'Bodygraph' ranged from 0.96 to 0.98 (p-value 0.000). ICC value for Intertester reliability of 'Bodygraph' was found from 0.81 to 0.97 (p-value 0.000). The study concluded that the 'Bodygraph' can be considered to be valid and reliable for measurement of Range of Motion of cervical lateral flexion.
