The article presents the biomechanical etiology of the so-called idiopathic scoliosis. The research was conducted in the years 1985-2013, but the importance of the observations connected with the so-called idiopathic scoliosis were completed in 2007 (4, 5, 6, 7, 8, 9). All types of spine deformity are proved to have a connection with gait and with standing “at ease” on the right leg. Every type of scoliosis begins to develop at the age of 2 - 3. The article provides short information about new screening tests and new exercises in the course of causal prophylaxis and treatment.
