Degenerative Thoracolumbar Deformity
Conditions
Brief summary
The purpose of this study is to measure functional activity and stability in spinal deformity patients utilizing motion analysis testing and accelerometers.
Interventions
DEVICETriaxial accelerometer
Monitors placed on the waist, thigh, and bilateral ankles. Accelerometry will measure patients' physical activities in the free-living environment for 4 consecutive days. The patients will wear the monitor during waking hours and remove it during sleeping, showering, and swimming time.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Motion Analysis Lab - Change in function | Baseline, 6-12 weeks post-surgery, 1 year | Spatiotemporal measures including velocity, step/stride length, step width, single/double support times, and R/L temporal symmetriesm will be used to measure function. |
| Motion Analysis Lab - Change in gait | Baseline, 6-12 weeks post-surgery, 1 year | Gait will be measured by segmental and joint range of motion, peak kinetics during walking, and changes in deviation from normal bands using sensory processing measures. |
| Motion Analysis Lab - Change in trunk stability | Baseline, 6-12 weeks post-surgery, 1 year | Trunk stability will be measured by EMG frequency content and activation pattern during gait and postural sway. |
