Navigate to the settings scene and choose Reset Preferences. This will allow all Tips Scene to show again.

It is important to follow the Tips shown in the Tips Scene. The most common reason for an inaccurate reading is moving the knee after the first Snap. It is important not to move the position of the knee during the test.

All records are currently stored locally on your phone. They are not stored on any server and therefore no one has access to them. The app is also password protected; the password created when first registering the app must be entered to access patient records.

We currently do not save copies of patient records on our servers for privacy reasons and therefore it is not possible to share patient records through the app. However, a screenshot of the results can be taken and shared via any existing platform such as email.

A marker is a simple circle that can be made at home as seen in below image. The application will detect any shape resembling a circle (it does not have to be a perfect circle, it can be hand drawn as shown below) but there has to be a good colour contrast between the background and the circle. Alternatively, you can use the printable marker below which can be printed in grayscale as well.

For the auto detect function to work there has to be a good colour contrast between the circle and the background as seen in the below image.

Knee range of motion and pain are important markers of knee function. Reduced motion and pain lead to dissatisfaction.  Measurement of knee function is used to establish the status of the knee and is particularly useful when monitoring recovery from knee injury and knee surgery. For example, knee stiffness can be problematic after procedures such as anterior cruciate ligament reconstruction and knee replacement. By monitoring knee range of motion, poor progress can be identified. This allows intervention, such as physiotherapy, to be implemented in a timely fashion to improve knee motion. Poor pain control can limit rehabilitation and compromise outcome. The app can provide a record of pain scores, which if high can alert the doctor to requirement for further investigation or increased analgesic requirements.

Both provide means of measuring knee range of motion, the results of which can be shared with doctors.

The gyroscope method is quick and easy to use and is ideal for the patient at home and for doctors or physiotherapists to use in the clinic setting.

The image test method requires another individual in addition to the test subject to take measurements.  It is therefore more suited to the clinic or research setting. The advantage of the image test method is that the positions of the virtual markers are clearly depicted in the result records and therefore flexion and extension range of motion measurements can be verified by the doctor.

The app provides a means of measuring and storing information relating to knee function. This allows patients to chart their progress during the rehabilitation process following knee surgery or injury.

Measurements of knee motion, pain scores and even images of the wound can be sent to the patient’s doctor by taking a screenshot of the results. Therefore in some cases this application can save a trip to their doctor for clinical assessment. This feature will be appealing to patients recovering from knee injuries or knee surgery who have difficulty walking or have long distances to travel

Results can be viewed in list form or graphical form to monitor patient progress across a set period of time.

There are two ways of measuring knee range of motion. It can be measured using the phone’s Gyroscope function by placing the mobile device on the thigh and then the lower leg.  Watch Video

Knee range of motion can also be measured with a novel, real time motion tracking system. Markers are placed on the side of the knee and also the thigh and lower leg.  Markers can easily be made at home and will work better if they contrast with the background.

The app will automatically track the three markers and provide a measure of knee range of motion. Watch Video

Alternatively, using the application, three virtual markers can be placed on the lower limb to track range of motion. Watch Video

The orthophysical app can measure knee range of motion, monitor wound healing and in addition can record knee pain and satisfaction scores.

The orthophysical mobile application provides a means of measuring and recording knee function.  It will appeal to orthopaedic surgeons, physiotherapist and in fact anyone who needs to measure knee function. It is particularly useful for monitoring recovery in those recovering from knee injury or after knee surgery.
