Do the stair step exercise. As previously mentioned, one common defect that can contribute to scoliosis is a difference in leg length. Step up on a stair with the longer leg. Lower the opposite leg to the floor as you bend onto one knee. While bending, raise the arm that is on the same side as your lowered leg up as high as possible. For example, if you are lowering your left leg, raise up your left arm.[4] Perform 2-3 sets of 5-10 reps of this exercise. Do it on the one side only. You can do this exercise daily.
