Understanding the Effects of the “Ankle Sprain Reducing Shoe” on Ankle Joint Kinetics, Kinematics, Electromyography, and Neuromuscular Balance Control: A Pilot Study

Institutional Review Board, Hospital for Special Surgery

February 05, 2010

The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

Summary

The purpose of this study is to understand the effects of footwear on preventing ankle sprains.  Specifically, this work will examine the effect of footwear on joint motions and loading.  It will also examine how different types of footwear affect ankle muscle control and one’s ability to balance.  Five subjects will be enrolled to participate in one laboratory visit that is expected to last 60 – 90 minutes.
