Highlights
- •Coordination variability was similar between uninjured and injured runners.
- •Exertion had minimal impact on coordination variability in all runners.
- •Presence or absence of pain did not appear to alter coordination variability.
- •Runners with iliotibial band syndrome had variable responses to the run to exertion.
Abstract
Background
Iliotibial band syndrome is a common overuse running injury which results in altered
mechanics. While injuries alter discrete mechanics, they may also cause a change in
coordination variability, the stride-to-stride organization of runners' movement patterns.
Uninjured and injured runners may experience a change in coordination variability
during a run to exertion due to fatigue, pain, or a combination of these factors.
The aim of the current study was to determine if runners with iliotibial band syndrome
and uninjured runners display different segment coordination variability across the
course of a run to exertion.
Methods
3D kinematics were collected as 13 uninjured runners and 12 runners with iliotibial
band syndrome ran on a treadmill. A modified vector coding technique was used to calculate
coordination variability during stance for segment couples of interest. Coordination
variability was compared between uninjured and injured runners at the beginning and
end of the run. The influence of pain on coordination variability was also examined.
Findings
There were no differences in coordination variability at the beginning or end of the
run between uninjured runners and those with iliotibial band syndrome. The change
in coordination variability due to the run was not different between uninjured runners,
injured runners who experienced no change in pain, and injured runners who did experience
a change in pain.
Interpretation
Runners do not constrain the patterns of segment motion they use in response to exertion
nor does it appear that occurrence of pain during running results in a differential
change in coordination variability.
