DrGoniometer vs DynamicGoniometerAR

Dr. Goniometer is a tool whereby physiatrists, orthopaedists and physiotherapists can measure the movement angles of their patient’s articulations and store all related data. It is the only tool supported scientifically by comparative studies on real cases, as mentioned hereunder. The tool enables the management of patient records, measurement of patient articulation angles and storage of all related information to build up historical data bases for each articulation and movement. Measurement is by photographing the articulation and identifying the pictures taken with three separate markers. Picture taking is supported with perpendicular reference to ground level, iPhone alignment identification and patient central position referencing. These data come from Medical Literature suggestions for completing this type of reliable measurement (Cf. for instance, Dunlevy C. et al. "Procedural considerations for photographic-based joint angle measurements", Physiother. Res. Int. 2005; 10(4): 190-200). Dr. Goniometer has been used in recent studies – the publication of which is currently under way – that have identified reliability and measurement errors comparable to those of professional measurement tools (such as the Universal Goniometer, Isokinetic Tools Goniometer and the like). The study "A new iPhone-based Goniometer (Dr. Goniometer): a Validation Study", in particular, reports that various measurements on several patients were made simultaneously with professional tools and Dr. Goniometer. Measurements with the latter were repeated by different physiatrists and physiotherapists and results indicate comparable measurement errors for the Dr. Goniometer and other tools. In addition to the above, further features are also available through in-app purchase to: - computer browse all Dr. Goniometer data (such as patient records, measurements, photos and the like) and print any patient articulation record; - backup all Dr. Goniometer data on the computer; - use a previously created back-up to restore all Dr. Goniometer data on any iPhone (as in the event of iPhone replacement or application re-installation, for instance). - export all measures in a Excel file through iTunes File Sharing, connecting your iphone and PC through the USB cable. All the above features are available with no additional computer software required, just a common Internet browser; any operating system is supported, whether Microsoft, Apple, or others. The iPhone and PC used must be on the same WiFi network for computer and Dr. Goniometer connection. Should no WiFi connection be available, if the iPhone is be connected to a mobile network and the PC to the Internet, the iPhone and computer connection will be based on the settings of the mobile network in use. Dr. Goniometer ensures constant measurement tool availability and access to patient data bases. New measurements can always be made at each patient visit, with no need for constant patient record updating as completed measurements are stored automatically on the iPhone or PC used and are retrievable whenever needed.

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. With the classic goniometer the position of joint should be registered in degrees in maximal and minimum position in order to calculate the range of motion of joints. Augmented reality (AR) offers a novel method of blending virtual and real word. The app is a powerful combination of these two environments which coverts Apple devices to expensive motion analysis tools. The dynamic nature or the app is that once the markers are recognised and captured, the three spheres are moving according to patient joint movement live and continuously following simultaneously the new position of each marker. This powerful feature offers a great help to surgeon in an effort to record in real time and in augmented reality the motion of the joint, and measure the range of the motion. The Dynamic 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 Augmented Reality (AR) directly angles, range of motion all dynamically while the patient is moving the joint of interest. The app automatically recognises, three different markers.The markers are assigned with three coloured spheres namely red, green, blue spheres which are connected with cylindrical lines. The measured angles and the complimentary values between the cylinders are printed continuously over the screen, while the minimum and maximum value and the total range of motion, are printed and updated also continuously. During the test, patient is not constrained by any device and has a total freedom of movement. It allows to carry out a medical examination while evaluation dynamically during movement of joint of interest is feasible . - marking points by pressing a key is not necessary, seeing the joint of interest tagged manually before by the printed unique QR codes images markers in screen, three points are captured and recognised immediately. Coloured spheres appear in AR over the printed Qrcode printed attached markers over the joint of interest which are moved respectively following the joint movement in real world. -angle values are printed continuously in real time. By ordering the patient to place the joint of interest in new position you notice that spheres are moving attached to the printed markers over the skin continuously in Augmented Reality environment, simultaneously measuring the angle subtended between the three spheres. -save the measured values and results as a screenshot to the photo roll for later review or consultation. The app is not a simple goniometer, is an enhanced product which helps to monitor objectively in real time the joint movements and evaluate live optimally the range of motions. This App is particularly useful especially in clinical settings where you need a detailed results without losing time. The combination of Augmented Reality environment and live monitoring the range of movement offers a new dimension in clinical examination. The ability to integrate-regardless of the camera position - live imagery and measure live the angles and estimating the range of motion by using as references certain printed reference markers concurrently makes the app a simple and useful tool. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! The DynamicGoniometerAR 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.
