Key result
Elderly women show inferior balance vs middle-aged women, with ~73% slower reaction times.
Why the study?
Age-associated decline in static and dynamic balance between middle-aged and elderly women was not well characterized.
Does static and dynamic balance decline with age between middle-aged and elderly women?
Cross-Sectional (n=102)
No
Does static and dynamic balance decline with age between middle-aged and elderly women?
Static and dynamic balance, particularly reaction time and movement velocity, decline significantly with age in women, suggesting a need for balance exercise programs.

May inform fall prevention strategies in elderly women; hypothesis-generating and requires prospective validation.
Purpose] The objective of the present study was to determine whether there is an age-associated decline in static (SB) and/or dynamic (DB) balance between middle-aged and elderly women.[Subjects and Methods] Volunteer middle-aged (MG) and elderly (OG) women were divided into two groups (OG, n= 53; MG, n= 49).Indexes of balance were used to measure SB and DB using a platform system.Reaction time (RT) and movement velocity (MVL) were derived for the DB index.[Results] All SB and DB parameters of the OG group were significantly inferior to those of the MG group, and the declines of RT and MVL in DB were remarkable.[Conclusion] Although large individual variations were found in balance ability, it was found that DB and SB declined with aging.The declines in RT and MVL in DB were particularly remarkable, indicating the need for a balance exercise program for the maintenance of neuromuscular and nerve functions.

Narita et al. (2015) conducted a cross-sectional in Age-related balance decline (n=102). Advanced age (Elderly group) vs. Middle-aged group was evaluated on Reaction time (RT) during dynamic balance assessment (p=<0.05). Elderly women demonstrated inferior static and dynamic balance compared to middle-aged women, with particularly remarkable declines in reaction time and movement velocity.
