The numbers that you describe are recordings of your range of motion. “Normal” range of motion (ROM) flexion-chin to chest, extension of 60, lateral bending of 45 and rotation of 90 degrees. These figures are for a young, normal, never injured individual. Most of us have restrictions in ROM due to degenerative changes, trauma and disorders of aging and disease.
I think the numbers noted as fractions (3/4, 1/2) are the indications of restriction from full ROM.
