Immediate changes in pressure pain threshold in the iliotibial band using a myofascial (foam) roller

Background Foam rolling is a self-release myofascial technique that can be applied to a variety of tissues. Previous studies have demonstrated physiological changes in range of motion and arterial stiffness with the application of a foam roller; however, no studies have investigated the change in pain levels. The present study investigated the effect on the pressure pain threshold (PPT) following the application of a foam roller for three minutes to the right iliotibial band (ITB) of asymptomatic participants. Methods Participants completed a questionnaire and had their height and mass measured. Three points on the ITB of the right leg were marked. The PPT was measured at each point using a pressure algometer. Measurements were taken pre-intervention, post-intervention and five minutes post-intervention. Participants completed a single three-minute bout on the foam roller. Findings Results demonstrated a statistically significant increase (p<0.05) in the PPT at the lower thigh immediately post-treatment; however, the difference was ameliorated five minutes later. Conclusions Foam rolling the ITB produces an immediate increase in the PPT of the lower thigh in asymptomatic participants.
