Abstract Background The current study investigated the repeatability test-retest reliability of ground reaction force parameters recorded during a voluntary step execution under single motor task and dual task motor and cognitive task conditions for healthy adults and elderly individuals as well as the number of trials required to produce repeatable results. Methods Twenty-four healthy adults 21-63 years old and 16 elderly adults 66-87 years performed a voluntary rapid step execution following a tap on their heel while standing on a force platform under single and dual task conditions on three separate occasions. The first two tests were performed 30-60
