简要总结
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":
- The Vestibular System: Located in the inner ear (detects movement).
- Proprioception: The body's "inner map" (sensing where your limbs are).
- Vision: Seeing the world around you to stay oriented.
The Goal of the Study Even though humans rely heavily on their eyes to stay balanced, the role of vision in scoliosis has not been studied very much.
This experiment aims to test the hypothesis that teenagers with scoliosis have trouble processing visual information to maintain their posture. By using advanced motion analysis, researchers want to see if a "misunderstanding" of visual cues is contributing to the spinal deformity.

结局指标
主要结局
Margin of Dynamic Stability
时间窗: At enrollment
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).
Center of Pressure
时间窗: At enrollment
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.
Extrapolated Center of Mass
时间窗: At enrollment
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.
