Scoliometers are used to measure the degree of trunk rotation in people with scoliosis and other spinal deformities. The idea is very simple, and the scoliometer is basically a level with a cutout for the spine, and specific degrees representing how much rotation is at each vertebral segment. It is a great screening tool for scoliosis, and is considered positive at 5 degrees and above.
The application has a Hold function to set an offset and a Reset. Minimum and Maximum degrees are stored.
