Motion Detection Application to Measure Straight Leg Raise ROM Using MediaPipe Pose

The straight leg raise test is one of the most common neurological tests of the lower limb tests in which the patient lies on an examination table with both legs extended. This test, also known as the Laségue sign, is considered positive if there is pain when applying pressure to the pyriform muscle and its tendons, especially when the hip is bent at a 90° angle and the knees are extended. The Straight leg raise test movement can be recorded using a webcam that can detect movement and track the position of the joints of human body supported by MediaPipe poses and an OpenCv library, in order to show the Straight leg raise movement by forming an image in the form of lines on both legs that make up the ROM and calculate the size angular as well as save in the database. The application display contains a new record menu where the respondent (patient) must fill in their identity, can see in the form of video recordings containing raw images and images that can detect ROM on SLRT movement then the results are in the database and exit the application. This application is expected to be used by medical practitioners, especially in the field of rehabilitation, by understanding the angle magnitude information in real time, quickly and accurately that, as a consequence, it can support the diagnosis of low back pain.
