Contact angle is an important property to quantify the wettability of a solid surface with liquid, which characterizes interactions solid-liquid pair. Generally, measure contact angle, special instruments such as goniometer are necessary, but they not readily available in certain research settings. In this study, alternative method based on Hele-Shaw cell, microscopy imaging, and image processi...

This document shows the development of a system to automatic measure of movility arches used to evaluate joint funtionality. The system applies digital image processing techniques to identify body markers, which are employed to estimate the movement amplitude. Results show good performance under differents scene configurations.Validation of the outputs is carried out by comparation with goniome...

Substantial advancements in markerless motion capture accuracy exist, but discrepancies persist when measuring joint angles compared to those taken with a goniometer. This study integrates machine learning techniques capture, an aim enhance this accuracy. Two artificial intelligence-based libraries—MediaPipe and LightGBM—were employed executing shoulder abduction angle estimation. The of ten he...

BACKGROUND The objective of the present study was to assess interobserver reproducibility (in terms of reliability and agreement) of active and passive measurements of knee RoM using a long arm goniometer, performed by trained physical therapists in a clinical setting in total knee arthroplasty patients, within the first four days after surgery. METHODS Test-retest analysis. SETTING Univers...

Purpose: Measurement error when determining the size of an angle is always an issue for clinicians. Computer assistance may help to decrease that error. The purpose of this study is to determine the amount of error when measuring Q-angles using a goniometer and the IMAGEJ program, a public domain program developed at the U.S. National Institutes of Health. Methods: Two investigators participate...
