Brief Summary

Scoliosis is more than just a curve in the spine; it is a complex, 3D twisting of the backbone. While it can be caused by birth defects or tumors, the most common type-idiopathic scoliosis-appears in healthy teenagers for no clearly known reason. The Theory of Balance Researchers believe that scoliosis might actually be caused by a "glitch" in how the body stays upright. Instead of the spine curving on its own, the curve might be the body's way of compensating for a poor sense of balance. To stay balanced, the human brain relies on three main "inputs":

1. 1.The Vestibular System: Located in the inner ear (detects movement).
2. 2.Proprioception: The body's "inner map" (sensing where your limbs are).
3. 3.Vision: Seeing the world around you to stay oriented.

Conditions

Idiopathic Scoliosis

Outcome Measures

Primary Outcomes (3)

• Margin of Dynamic Stability

  This measures how close a person is to losing their balance while moving. It calculates the distance between where the body's weight is moving and the edge of the person's "footprint" (base of support).

  At enrollment

• Center of Pressure

  The point on the ground where the most weight is being concentrated. Tracking how much this point "wobbles" or shifts shows how hard the body is working to stay upright.

  At enrollment

• Extrapolated Center of Mass

  A calculation that looks at both the position of the body and its velocity. It helps researchers predict if the person's momentum is about to carry them off-balance.

Motion Analysis OTHER

Researchers use motion capture to track exactly how a patient's body moves and shifts in response to different environments.
