Changes in physical function of frail elderly females in the one-year long-term care prevention program

[Purpose] This study investigated changes in the physical function of frail elderly females who participated in a long-term care prevention project for ≥1 year. [Participants and Methods] There were 125 females included. Measurement items were body mass index, 5-m maximum gait time, 5-m normal gait time, standing on one leg with eyes open, timed up and go test, and grip strength and measured every six months. [Results] Grip strength decreased significantly after six months and one year compared to that of the start. The other measurements had no significant differences at start, after six months, and after one year. [Conclusion] This study investigated changes in physical functions in the frail community-dwelling elderly females one year after starting in a long-term prevention care program. Consequently, after one year in the program, no change was noted in measurements, such as gait speed, but only grip strength decreased. Likely, the exercise program mainly targeted the lower limb muscles. Therefore, although functions mainly use the lower limbs, such as walking, may be maintained, those using the upper limbs may be affected by aging.
