Compilation of a Registry of Normal, Healthy Runners for the Purpose of Comparison to Pathologic Individuals and Populations

IRB Number: 28031

Institutional Review Board, Hospital for Special Surgery

March 17, 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.

100 runners, 50 male and 50 female, will be enrolled in this registry.  Subjects will take part in a comprehensive analysis of their running mechanics, strength, structure, muscle function, and foot pressure patterns.  All data will be collected during 1 visit that will last approximately 3-4 hours. This study will not require any additional time commitment from normal, uninjured participants recruited from other running-related studies.

Inclusion/Exclusion Criteria

Inclusion Criteria:

All subjects must be:
• Between the ages of 18 and 65 years old
