Falls leading to osteoporotic fracture is a substantial issue clinically. By
inference from the literature, women with osteoporosis who are classified as
having a history of falls may not represent a distinct homogeneous population.
However, studies exploring the potential heterogeneity within fallers in women
with osteoporosis are scarce. The objective of this study was to better
understand the physical function characteristics of women with osteoporosis, with
and without a previous history of falls, by further stratifying them based on
their single-leg stance (SLS) performance. Eighty-seven consecutive,
community-dwelling women with osteoporosis were recruited from the Endocrinology
Clinic at Singapore General Hospital. Laboratory-based and clinic-based standing
balance tests, a lower limb strength test, and the 6-min walk test (6MWT) were
measured. Fallers and non-fallers did not differ in standing balance, lower limb
strength nor the 6MWT (P's>0.08). SLS performance was an independent predictor of
the various functional measures, after adjusting for age and body mass index.
Specifically, an increase in SLS time was associated with lower standing
center-of-pressure velocities, greater lower limb strength, and greater 6-min
walking distance. When the two groups were stratified based on their recent
history of falls and clinic-based standing balance performance (SLS time),
fallers with good SLS time (>30 s) showed better functional outcomes than did
non-fallers with poor SLS time
(</=30 s) (P's<0.08) and comparable functional
outcomes with non-fallers with good SLS time (P's>0.11).
The results indicate an
important heterogeneity within fallers and non-fallers with osteoporosis and they
argue for a individualized approach to rehabilitation.
