“…Among the methods that use photogrammetry in combination with computer techniques are the DIPA (Digital Image-based Postural Assessment) software and protocol, which together allow the assessment of different body segments in the sagittal and frontal planes, thus providing clinical information on posture in individuals. 12,13 Previous studies have confirmed the reproducibility and validity of linear spine measurements in the sagittal and frontal planes, 12 and angular spine measurements in the frontal plane, 13 obtained using the DIPA software. However, there is a need to validate the angular values and clinical diagnosis obtained with the DIPA software for the spinal curvatures in the sagittal plane.…”

“…Therefore, the present study aims to analyze the concurrent validity of the DIPA postural assessment method in relation to radiography for identifying the magnitude and classification of thoracic kyphosis in adults. Based on our previous studies, [12][13][14] our hypothesis is that the magnitude of the angle of thoracic kyphosis measured using the DIPA software will agree with that measured using radiography. Similarly, it is thought the DIPA software will provide an accurate classification of the thoracic kyphosis.…”

Objective: To analyze the concurrent validity of the Digital Image-based Postural Assessment (DIPA) method for identifying the magnitude and classification of thoracic kyphosis in adults. Methodology: On the same day and in the same place, thoracic kyphosis was assessed in 68 adults using 2 methods: the DIPA software protocol and radiography. The DIPA software provided angular values of thoracic kyphosis based on trigonometric relations, while with the radiograph, the curvature was calculated using the Cobb method. The following tests were applied in the statistical analysis: Pearson's correlation, Bland-Altman's graphic representation, root mean square error, and receiver operating characteristic (ROC) curve; a = 0.05. The reference angular values for the standard thoracic posture used in DIPA were determined with the ROC curve based on the Cobb angles. Results: The correlation between the angles obtained for thoracic kyphosis using the DIPA and Cobb methods was found to be high (r = 0.813, P < .001), and the accuracy was §4°. According to Bland-Altman's representation, the magnitudes provided by the DIPA software were in agreement with those of the Cobb method. In reference values for determining the standard posture of the thoracic spine, the ROC curve indicated good accuracy in diagnosing a decrease in thoracic kyphosis (with a value of 33.9°) and excellent accuracy in diagnosing thoracic hyperkyphosis (with a value 39.9°) when using DIPA. Conclusion:The DIPA postural assessment method is valid in the sagittal plane for identifying the magnitude of thoracic kyphosis in adults. Furthermore, it is accurate in diagnosing alterations in thoracic kyphosis.

“…The evaluation protocol consisted of: (1) evaluation of the static posture by digital photogrammetry based on the protocol of the 'Digital Image-based Postural Assessment' software (DIPA © ) [27,28]; (2) determination of the neck flexor muscle endurance by the neck flexor muscle endurance test [29]; and (3) determination of the ROM of the cervical spine using a fleximeter [30]. The validity and reproducibility of the DIPA © software protocol, the Fleximeter and the muscle endurance test have been duly confirmed [21,27,28,31,32]. The results of the evaluations were analyzed by a researcher who did not take part in the evaluations, thus avoiding evaluation bias.…”

“…The photographic records based on the DIPA © protocol [27,28] were obtained using a digital camera (Sony Cyber-Shot Dsc-w510 12.1 megapixels) fixed to a tripod 95 cm above the ground at a horizontal distance of 280 cm from the subjects under evaluation. Two reflexive markers fixed to a plumb line, at a distance of 100 cm one from the other, were used as the vertical reference, and the horizontal reference was assumed to be perpendicular to the plumb line.…”

Introduction: Factors such as postural changes, reduced neck muscle endurance and reduced range of motion (ROM) are common characteristics attributed to people with neck pain. Objective: (a) Identify differences in postural, muscular endurance and ROM characteristics between individuals with and without neck pain and (b) relate the presence and intensity of neck pain with the characteristics of static posture, muscular endurance and cervical ROM. Method: A cross-sectional study with 60 subjects equally divided into two groups with respect to the presence of neck pain carrying out the following evaluations: (1) static postural evaluation by digital photogrammetry; (2) the neck flexor endurance test; and (3) evaluation of cervical ROM using a fleximeter. The data were analyzed with independent t-tests, the Mann-Whitney U test, and the Spearman and Tau of Kendall correlation tests (α < 0.05). Results: There were no statistical differences between individuals with and without neck pain regarding the postural, muscle endurance and cervical ROM characteristics. No statistically significant correlations were found between pain and posture, muscle endurance and cervical ROM. Conclusion: Individuals with neck pain do not appear to present differences in their postural, neck flexor muscle endurance or cervical ROM characteristics when compared to individuals without neck pain, and neck pain appears to be unrelated to these variables.

“…One-way Anova was performed, followed by the Bonferroni post-hoc test, in addition to the Kendall Tau B correlation test (τ). The correlation coefficient τ was classified as: strong (above 0.5), moderate (between 0.5 and 0.3) and weak (below 0.3) 19 . The square eta (ŋ 2 ) was classified as: small (0.02), medium (0.13) and large (0.26) 21 .…”
