ITBS intrigue: Fatigue leads to decreased hip adduction

Women with iliotibial band syndrome (ITBS) independently modify their running gait when fatigued to decrease hip adduction, potentially as a result of pain, according to research from Rutgers University in Newark, NJ, that may have implications for gait retraining.
