The present study showed that 80.5% of elderly population
were independent before trauma; this reached to
13.5% and 22.5%, 1 and 3 months after trauma. The lowest
score of ISADL was reported one month after trauma.
Inaba et al. reported that most elderly (98%) were living
independently at home before injury. However, at longterm
follow-up (a mean of 2.8 years), only 63% were living
independently and 20% still required homecare (18).
Besides, Gill et al. reported that 43.8% of elderly fallers
had no recovery after one year (19). Sipila et al. reported
that only 40% of hip fracture survivors recovered to their
prefracture ambulatory level and only 20% recovered to
their prefracture level in advanced mobility tasks 6 weeks
after discharge (14). Kelley-Quon et al. also reported that
ADL scores declined after 12 months of trauma (20). These
findings were probably due to the fact that the elderly
were at rest until a month after trauma, but three months
after trauma were launched by using aids and had begun
rehabilitation. These findings suggest that prevention
and treatment of trauma should be a high priority
when decisions are made to allocate resources aimed to
reduce the burden of disability in older persons. More
than a half of participants were women. This finding is
consistent with the results of Buczak-Stec et al. in Poland
reporting that hospitalization ratio due to falls was much
higher for women than men (21). Fracture occurs probably
in reduced bone mass and impaired bone geometry
in older women (11). Multiple regression analysis showed
that gender had an association with ISADL one month
after trauma and women showed a better improvement
in their ISADL. The reason might be that women receive
more support after trauma. Many studies showed that
perceived support has a direct effect on health and wellbeing
of older adults (22). Gill et al. reported more disability
in women after trauma (23). Moreover, Gonzalez
et al. reported that women with wrist fractures exhibited
