The Spine Kinematics and Center of Pressure Excursion During Functional Task Vertebral Compression Fractures Subjects

Study Overview
=================
Brief Summary
-----------------
This study aimed to assess the sensory and kinematic components of the limits of stability (LOS) test in patients with vertebral compression fracture (VCF) .

Detailed Description
-----------------
This study enrolled adults with VCF (VCF group), older adult without spinal deformity (NE group), and young adults (NY group). The Biodex balance system was employed to calculate the balance score and the LOS of participants. An inertia motion system was used to record kinematic data. The center of pressure (COP) signals of postural stability and LOS were used to calculate the frequency power spectrum for interpreting the sensory component.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postural Stability | A balance system was employed to calculate the standing posture sway score.A high score was indicative of excessive movement during the test and thus, poor stability. The range of value was 0.3- 4.1. | 90 second | 
| limits of stability | patients shift their center of gravity from the center target to a blinking target and back to the center target.This process was repeated for each of the 9 targets. A high score was indicative of fine direction control.The range of value was 21- 66. | 1-2 minutes | 
| Kinematic Data | The movements of the head, upper spine, lower spine, pelvis,hip, thigh, and knee were measured using 6 inertial measurement units. | 5 minutes | 
| timed up-and-go test | sit-stand-walk-180° turning-walk and sitting down task | 90 second |
