摘要

Obese aging population is increasing in the United States, and obese elderly experience fall twice asfrequent as their lean counterparts. However, the mechanisms of older obese adults fall are still not clear. Itis not known whether the obese elderly has more functional mobility impairments than their leancounterparts, and consequently have increased risks of falls. It was hypothesized that obese elderly havemore functional mobility impairments compared with their healthy weight counterparts. Six lean and sixobese community-dwelling elderly participated in the study. "Timed up&go" test was used to quantify thefunctional mobility for both lean and obese elderly. Stopwatch and custom-made inertial measurementunits were used to obtain the temporal and kinematic parameters. The results showed that there is nosignificant difference in overall time to complete the "timed up&go" task, but significant difference inanterior posterior acceleration, time to reach the peak extension angular velocity from initiation and doublesupport time between lean and obese groups of participants. Therefore, we concluded that older obeseadults have some functional mobility impairments compared with their lean counterparts but thecompletion time of the "timed up&go" test may not be able to differentiate these individuals. Our resultsalso suggested that obese elderly might have more muscular impairments than their healthy weightcounterparts, which can result in higher fall risks. Future studies are warranted to investigate themechanisms of increased fall risks among obese elderly.
