What is a posture analyzer?
PT-Posture Analyzer is used to evaluate the human skeletal system and show the degree of anomalies or asymmetries. Using photogrammetric technology, the postural analysis device evaluates the anomalies of the spine and skeleton of the human body, the asymmetries in the human body and the deviations of the axis of the human body. The device includes a digital camera, calibration banner, markers and software as a simple user interface.
How to use a posture analyzer?
To use the posture analyzer, the examiner is placed in front of the calibration screen naked or in thin clothing attached to the body. According to the protocol defined in the manual of the device, important points such as left or right tragus, left and right extremities, large trochanter of the left and right femur, left and right ankle (malleolus), etc. are marked with colored markers.
The camera mounted on the stand is located at a certain distance from the banner and is connected to the computer/software via USB port. The person stands naturally in three front, back and side views of the device camera. In the software of the device, the images are recorded in three views and the amount of deviations and asymmetries are compared with the normal range, and if there are any anomalies, it is explicitly mentioned.
Why is automatic calibration so important in a posture analyzer?
It should be noted that the distance of camera to calibration banner and the angle of view of the camera to this banner is very important in common posture analyzer device. Changes in this angle or distance can change the test results! As a result, if the technology of the device is such that it can eliminate this dependence on environmental conditions, it can solve the biggest problems of using this device. PT-Posture analyzer uses automatic calibration. Perform the analysis as accurately as possible without worrying about moving the device.
