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.
Orthophysical
This app helps measure and monitor knee range of motion using image capture or gyroscope technology. It also tracks pain and satisfaction levels and allows physicians to monitor wound healing. Results can be stored and viewed graphically or in a list.
- Knee range of motion measurement (image capture/gyroscope)
- Pain and satisfaction level monitoring
- Wound patient healing monitoring
- Graphical and list data storage
- Functional testing system
- Image capture with marker detection

The orthophysical app provides a means of measuring and monitoring knee range of motion. This app also provides new features to monitor pain and satisfaction levels through a simple functional testing system. Additionally, physicians can monitor wound patient healing using the Wound Inspection feature. Using the App, Knee range of motion can be measured with two different techniques comprising an image capture or a Gyroscope system. Once obtained, range of motion measurements can be stored and viewed in graphical and list form. The Gyroscope system provides a quick and easy way to measure knee range of motion. This features allows you to use your mobile device as a goniometer to measure knee range of motion with the gyroscope function. Knee flexion and extension are measured by placing the edge of the device on the thigh and shin and clicking the snap button. With the image capture system virtual markers are placed over the upper leg, knee and lower leg to determine knee range of knee motion. An additional feature is also available in this mode where the app auto detects circular markers physically placed on the patient to substitute the virtual markers selection process. Pictures of surgical wounds can be captured, labeled and archived using the Wound Inspection feature. Images can be viewed later by date. The orthophysical application can also be used to measure pain and satisfaction scores using the Functional Test Feature. A 5 point scale is used to measure satisfaction. Pain scores are recorded using an 11 point visual analogue scale ranging from 0 to 10. Results can be saved and viewed later in graphical or list form This app will appeal to Orthopaedic surgeons, physiotherapists and other healthcare professionals who need to measure their patients knee range of motion. It is ideal for use in the clinic setting although can also be used by patients at home to monitor their knee range of motion during rehabilitation following injury or surgery.
