Erratum to "Design of patient-specific gait modifications for knee osteoarthritis rehabilitation"

On page 1687 of the September 2007 issue, the title of the above-named article, as well as the title on the running head, the word "Rehabilitation" was misspelled as "Rhabilitation." The correct title should be "Design of Patient-Specific Gait Modifications for Knee Osteoarthritis Rehabilitation."
