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 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.
660 studies on the registry are indexed under Scoliosis; 186 are open to participants now.
This study's planned enrollment of 70 is above the median of 45 across 386 interventional studies indexed under Scoliosis.

Other: Motion Analysis
Researchers use motion capture to track exactly how a patient's body moves and shifts in response to different environments.
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).
Time frame: 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.
Time frame: 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.
Time frame: At enrollment
Base of Support
The total area on the ground occupied by the feet. A wider BoS often suggests the subject is trying to create a "wider stance" to feel more stable.
Time frame: At enrollment
Visual Field Perception
The "Distance Error." Using a joystick, the patient tries to place a 3D avatar exactly halfway between two other figures. The difference between the true middle and where the patient thinks the middle is reveals if their depth perception is distorted.
Time frame: At enrollment
Subjective Visual Vertical
Angular Error. A glowing line is tilted on a screen, and the patient must tell the operator how to rotate it until it is perfectly vertical.
Time frame: At enrollment
Started Apr 2026 (actual). Primary completion is estimated for Sep 2027, 16 months after the start.
Of 223 non-industry interventional studies with no phase under Scoliosis, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 58. This study's planned 16 months is below that.
Counting every sponsor, half of 233 studies reached it within 22 months; a quarter within 8 and three quarters within 60.
How these figures are worked out, and which studies are left out of them.
