4. Analyse the positions where it hurts while dancing to see if range can be improved in other areas - If it is starting to hurt while you are are dancing I would take a very close look at the exact position of your spine when this is happening. For instance, if it's when you lift the right leg into an arabesque, you may feel pinching and some soreness down in the lower back. Some areas that you could look into Look at the extension and rotation flexibility and control in the upper back and also the flexibility of the deep hip flexors. If both of these are tight this will jam up in the low back and you may feel some pain. This can happen in people without a scoliosis as well so don’t be alarmed, it just means that you need to improve your technique!
Get your Osteopath to assess, and if needed, release any excessive tension in your deep hip flexors (Psoas Major) to open out the front of the hip, and include some gentle lengthening techniques for the hip flexors. You will probably also need some mobility work for the upper body as well (such as the Thoracic Mobility and Improving Hip Extension sections of The Front Splits Fast Flexibility Program).
5. Free up all of the joints in the Thoracic Spine in all directions - Please note: When working with the mobility of the upper body. It is important to include side flexion and rotation movements as well as flexion and extension to really loosen up the facet joints in the upper back. Simply pushing into extension often will cause pain rather than increasing mobility.
