(HealthDay News) -- Scoliosis is a condition in which the spine is twisted or curved unnaturally, often in a "C" or "S" shape. Typically diagnosed in childhood, the condition sometimes requires surgery or a back brace to help straighten the spine.

Since the unusual shape of the spine is not always visibly noticeable, the Nemours Foundation lists these other common symptoms of scoliosis:

• The body tilts to one side.
• One shoulder blade is higher than the other.
• An uneven waist.
• One leg appears shorter than the other.
