Evaluation of Patients' Posture and Gait Profile After Lumbar Fusion Surgery by Video Rasterstereography and Treadmill Gait Analysis

DOI: 10.3791/59103-v
What you'll learn
  • ✓ Perform video rasterstereography to assess postoperative spinal posture objectively
  • ✓ Conduct treadmill gait analysis using integrated sensor mat technology
  • ✓ Interpret quantitative posture and gait data for postoperative functional evaluation
  • ✓ Compare pre- and post-fusion patient biomechanics using standardized protocols
Protocol

Here, we present a protocol to analyze the posture and the gait of patients after lumbar fusion surgery by means of high-resolution video rasterstereography and a treadmill equipped with an integrated sensor mat. Allowing critical functional postoperative evaluation on a less subjective level may enhance accuracy and reliability of indication for surgery.

Difficulty
advanced
Total time
~45–60 min per patient (rasterstereography + treadmill analysis + data processing)

Steps

1
Recruit and prepare lumbar fusion patients

Identify eligible post-lumbar fusion surgery patients and prepare them for analysis. Ensure proper clothing and positioning for video rasterstereography imaging.

2
Perform rasterstereographic posture analysis

Use high-resolution video rasterstereography to capture 3D spinal curvature, sagittal alignment, and postural parameters. Acquire images with patients in standing position.

▶ 02:30
3
Conduct treadmill gait analysis with sensors

Have patients walk on a treadmill equipped with an integrated pressure-sensitive mat to measure spatiotemporal gait parameters, stride length, and symmetry.

4
Interpret rasterstereographic and gait results

Analyze quantitative posture and gait data from both modalities to evaluate functional recovery and establish objective outcome measures for surgical indication.
