Hypothesis

This study aims to evaluate the inter-trial and inter-session gait variation including pelvis kinematics and the effect of clothing within and between sessions.

Conclusion

The study found that variation in markerless motion capture data was within suggested thresholds of reliability for healthy adults.

Supporting Evidence

  • Average inter-trial variation was less than 2°.
  • Inter-session variation was less than 3°.
  • Inter-session-clothing variation was less than 3.5°.
  • Root mean square differences between clothing conditions were less than 2°.

Takeaway

This study looked at how wearing tight or loose clothes affects walking measurements. It found that the type of clothing doesn't really change the results much.

Methodology

Twenty-two healthy adult participants walked while their gait was recorded using a markerless motion capture system in both tight and loose clothing.

Limitations

Variation in clothing conditions and walking speed between sessions were not controlled, and only right side gait data was considered.

Participant Demographics

22 healthy participants (8 females, 14 males; mean age 25 years) without lower-limb injuries.
