Reliability of three-dimensional kinematic gait data in adults with spinal cord injury

This study investigates how consistent measurements of walking are when using 3D gait analysis on adults with spinal cord injuries. They wanted to know if the measurements are reliable when taken on different days (inter-session) and within the same day (intra-session). The researchers used infrared cameras and reflective markers to track the movement of participants. They then analyzed the data to see how much the measurements varied between sessions and within sessions. The study found that the gait measurements were generally reliable, meaning that the measurements were consistent. However, measurements of hip rotation were less reliable, suggesting that caution is needed when evaluating hip rotation in this population.

• 1
  High inter- and intra-session reliability were found for most kinematic gait variables, indicating small intrinsic variation of gait.
• 2
  Inter-session reliability for hip rotation was moderate, suggesting caution is warranted when evaluating hip rotation.
• 3
  Small changes are required to exceed measurement errors for kinematic variables, except for hip rotation.
