In recent years, there has been an increase in geriatric population worldwide (1). According to the recent studies, elderly population of the United States has been growing rapidly since 1980 at a rate of 21%. By the year 2040, this percentage is estimated to reach nearly 20% of the total population in the US (2). This trend can be seen in many other countries including Iran. More than 7% of Iran population is elderly (3). The incidence of health problems increases in this age group, such as cognitive impairment, chronic diseases, and musculoskeletal disorders (1). The elderly consume 29% of medical care costs (4). The propensity for fall-related injury in elderly is due to a high prevalence of clinical diseases (e.g. osteoporosis, impaired vision, impaired balance) and age-related physiologic changes (e.g. slowed protective reflexes), which make even a mild fall particularly dangerous (5, 6). In a study performed in Iran, Adib Hajbaghery and Masoodi Alavi found that hip fractures due to osteoporosis occur 10 years sooner than developed countries showing a high risk of fractures in elderly in this country
