Synopsis: Reducing and eliminating knee pain referred to as patellofemoral pain (PFP) in female runners.

Introduction

Hip exercises found effective at reducing, eliminating common knee pain in runners - Indiana U. research at the American College of Sports Medicine annual meeting.

Main Item

A twice weekly hip strengthening regimen performed for six weeks proved surprisingly effective at reducing, and in some cases eliminating,- knee pain referred to as patellofemoral pain (PFP) in female runners.

The study by Tracy Dierks, assistant professor in the Department of Physical Therapy at Indiana University-Purdue University Indianapolis, was based on the theory that stronger hips would correct running form errors that contribute to PFP, even though study participants were given no instruction in gait training. The study used a pain scale of 0 to 10, with 3 representing the onset of pain and 7 representing very strong pain, the point at which the runners normally stop running because the pain is too great. The injured runners began the six-week trial registering pain of 7 when they ran on a treadmill and finished the study period registering pain levels of 2 or lower; i.e. no onset of pain.

"I wasn't expecting such huge reductions, to be honest," Dierks said. "We've had a couple of runners who have been at level 2, but the overwhelming majority have been a 2 or below."

PFP, one of the most common running injuries, is caused when the thigh bone rubs against the back of the knee cap. Runners with PFP typically do not feel pain when they begin running, but once the pain begins, it gets increasingly worse. Once they stop running, the pain goes away almost immediately. Dierks said studies indicate PFP essentially wears away cartilage and can have the same effect as osteoarthritis. His study participants showed many of the classic signs of PFP, the most prominent being their knees collapsing inward when running or doing a squat exercise move.

The pilot study thus far involved five runners and a control group that comprised another four runners. Hip strength measurements were taken before and after the runners in the control group maintained their normal running schedule for six weeks. Hip strength measurements were taken for all of the runners before and after the next six-week period in which they all performed the hip-strengthening exercises. The exercises, performed twice a week for around 30 to 45 minutes, involved single-leg squats and exercises with a resistance band, all exercises that can be performed at home. This study is part of an ongoing study involving hip exercises and PFP pain, with 11 runners successfully using the intervention. Dierks said he plans to seek funding to test the exercises on a larger group of runners.

Earlier research had focused on the feet as a possible root of PFP, with studies only recently looking more closely at the hips. Dierks said studies have found an association between PFP in women and weak hips, but his study is the first to test a possible treatment. He noted that PFP is considered "multi-factorial," so his study is examining one of several possible causes of the pain.

Dierks will present the findings of his study, "The effect of hip muscle strengthening on pain when running in females with patellofemoral pain," on Friday, June 4, at 4:15 p.m. during the gait analysis II session.

Co-investigators are Zachary H. Gergory, Rebecca L. Phipps and Peter A. Altenburger, all of IUPUI.
