Validity of PostureScreen Mobile® in the Measurement of Standing Posture

摘要: Validity of PostureScreen Mobile® in the Measurement Standing Posture Breanna Cristine Berry Hopkins Department Exercise Sciences, BYU Master Science Background: is an app created to quickly screen posture using front and side-view photographs. There currently a lack evidence that establishes (PSM) as valid measure posture. Therefore, purpose this preliminary study was document validity reliability assessing static standing Methods: This experimental trial which 50 male participants assessed total six times two different methods: Vicon 3D motion analysis system (VIC). Postural deviations, measured during trials PSM assessments (3 with 3 without anatomical markers), were compared postural deviations VIC criterion measure. lateral displacement on x-axis (shift) rotation y-axis (tilt) made head, shoulders, hips frontal plane. forward/rearward Z-axis hips, knees sagittal evaluated by comparing measurements shift tilt each body part VIC. Reliability variance measurements. The statistical model employed Bayesian framework consisted scaled product likelihood data given parameters prior probability densities for parameters. Results: tended overestimate plane underestimate Use markers did not universally improve PSM, most cases, exceeded patterns intraclass correlation coefficients (ICC) suggest high trial-to-trial variation Conclusions: We conclude until research further app, it should be used or clinical applications when accurate are necessary serial will performed. health fitness professionals screening tool, described manufacturer. Due suspected posture, we question usefulness single assessment.
