Shoe characteristics and balance in older women
1Prince of Wales Medical Research Institute, Randwick, N.S.W., Australia.
Objective:
To determine whether shoe characteristics affect balance in older women.
Design:
Randomized order, cross-over, controlled comparison.
Setting:
A retirement village.
Participants:
Thirty women aged 60 to 89 years (mean 78.7 SD = 8.5). Twenty-five subjects were hostel residents, and five were living independently in the community.
Outcome Measures:
Postural sway, maximal balance range, and co-ordinated stability.
Main Results:
The subjects underwent assessments of static balance (body sway) and dynamic balance (maximal balance range and co-ordinated stability) under four conditions: (1) barefoot, (2) in standard low-heeled shoes (walking shoes), (3) in standard high-heeled shoes, and (4) in their own shoes. Manova analysis revealed a significant overall shoe condition effect -- subjects performed best in bare feet or low-heeled shoes and worst in high-heeled shoes. There were no significant differences between subjects with and without foot abnormalities in any of the balance measures or test conditions.
Conclusion:
These findings suggest that bare feet and walking shoes maximize balance, whereas high-heeled shoes constitute a needless balance hazard for older women.
