Adult Spinal Deformity Surgery and Functional Reach Study

This observational study is looking at how spinal fusion surgery for adult spinal deformity (a condition where your spine has an abnormal curve) affects your ability to balance and reach. Researchers want to see if a new balance test, called a functional reach test, can better measure how well you can balance during everyday activities. They will compare balance measurements in adults with spinal deformity before and after spinal fusion surgery, and also compare them to healthy adults. The study aims to enroll 30 participants and is currently unclear about its recruitment status. Success will be measured by changes in your functional reach distance, and how much you sway and how fast you sway when standing, both before and after surgery.

Study design
This is an observational study that will include 30 participants. It will compare adults with spinal deformity undergoing spinal fusion to a control group without intervention.
What's involved
If you have adult spinal deformity and are having spinal fusion surgery, you will have balance assessments before surgery and at 3, 6, 12, and 24 months after surgery.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 24 months after their spinal fusion surgery.

What this trial measures

  • Functional reach distanceAssessed preoperatively and at 3, 6, 12, and 24 month postoperative follow-ups

    The distance a participant can reach forward (in cm), to the side, and 45 degrees to the side with each arm

  • Center of pressure sway rangeAssessed preoperatively and at 3, 6, 12, and 24 month postoperative follow-ups

    The range (in mm) that the participant's center of pressure moves in sagittal and coronal plane directions during the functional reach tests

  • Center of pressure velocityAssessed preoperatively and at 3, 6, 12, and 24 month postoperative follow-ups

    The maximum and average velocity (in m/s) that the participant's center of pressure reaches during the functional reach tests

  • Center of pressure excursionAssessed preoperatively and at 3, 6, 12, and 24 month postoperative follow-ups

    The summation of the distance (in mm) that the participant's center of pressure moves during the functional reach tests
