This goniometer tool can be used to measure angles at various times in a video. Designed for rehabilitation professionals. Features: • Capture new videos or import existing videos from your library • Step frame-by-frame through a video, or drag the slider to seek to a specific time • Select points and drag them into place • Lines and angle measurements automatically appear, connecting the points • Repeat with more frames, points, and angles • Export to spreadsheet (.xlsx format) for further calculations and analysis (note that there are multiple worksheets - one with raw point coordinates, and one with angle measurements) Make sure to capture your video directly perpendicular to your subject, with the camera level in all planes, and without panning the camera. The display of angle labels can be turned on/off in the app's preferences, found in the Settings app. App developer: Nathaniel J. Cochran, in collaboration with Regina Harbourne Supported by Duquesne University, Physical Therapy Dept. in the Rangos School of Health Sciences Developed in part to support a grant from the Institute of Education Sciences, US Dept. of Education

About

ARorthopaedicGoniometer

This app uses augmented reality to accurately measure joint range of motion. It allows medical professionals to easily record and save measurements directly from their device's camera, offering a precise and convenient alternative to traditional goniometers.

Highlights
  • Augmented reality angle measurement
  • Accurate joint range of motion estimation
  • Live camera feed measurement
  • Save measurements as screenshots
  • Adjustable pointer calibration
  • Intuitive point selection

Range of motion by measuring angles is frequent need in every day clinical tasks during patient examinations by orthopaedic surgeons, physicians, physical therapists and veterinarians. Commonly used method is to measure manually with a classical goniometer the range of motion of a patients joint. Often these manual measurements are inaccurate and depend on the individual interpretation. Augmented reality (AR) offers a novel method of blending virtual and real word. The measured angles with the advent of the augmented reality technology delivers accuracy and repeatability. Expensive motion capture data system offers Augmented Reality (AR) but this are a privileges of special costly scientific labs. Apple developed and popularised (AR) Augmented Reality technology readily available for its devices, thus miniaturising expensive high tech labs inside your iPhone in front of you screen. The AR orthopaedic GoniometerApp is medical software aimed for orthopaedic surgeons, physicians, physical therapists and veterinarians providing tool that allow doctors to: - determine the most accurate possibly way, in live images directly from your the camera in space angles thus estimating easily range of motion. By marking three points by touching over with the phone’s screen a colourful sphere is printed in augmented reality each time while seeing the joint of the patient in screen. -Angle values are printed sequentially after measurement on the screen, while you can continue measuring and choosing another set of three new points of interest, by easily ‘grabbing’ the last two points of measurement , without loosing their last positions. By ordering the patient to place his extremity in new position you can register, while seeing the last measurement in space in Augmented Reality. -Point tip sphere is the ’ target cross’ from which the spheres appears during registration each time the screen is touched. The positional calibration of pointer tip sphere in AR can be easily done by allowing the user to adjust the XYZ position of the pointer tip sphere by pressing the directions buttons accordingly. This feature enhanced the accuracy of sphere placement during measurement over joints in Augmented Reality (AR). -Save the measured values and results as a screenshot to the photo roll for later review or consultation. Augmented reality offers precision and accuracy because points are taken in 3D space. During the test patients are not constrained by any device and have a total freedom of movement. The ability to integrate -regardless of the camera position - live imagery and measure the angles and estimating the range of motion concurrently makes the app a simple and useful tool in clinical setting. In a busy everyday practice, measuring angles by the classic way namely classic orthopaedic goniometers , is time consuming and cumbersome. Orthopaedic goniometers must be not be physical present any more. The app offers a very convenient and accurate way to perform measurements of angles in space . The app is not a simple goniometer, is an enhanced product which helps to monitor objectively the course of the treatment and evaluate optimally joint motions. This App is particularly useful especially in clinical settings where you need a quick results without losing time. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! The ARorthopaedic Goniometer App indicated for assisting healthcare professionals. Clinical judgment and experience are required to properly use the software. The software is not for primary image interpretation.
