The aim of this study was to conduct an exploratory analysis of fear
of falling (FoF), balance, gait, and strength impairments and future physical
activity in women with multiple sclerosis. DESIGN: This prospective study
followed a convenience sample of 99 women with multiple sclerosis for 1 yr. The
participants were assessed on FoF and perceived mental health by questionnaire.
Objective measures included Limits of Stability, the Sensory Organization Test,
and the Functional Ambulation Profile. Strength was quantified by knee extensor
power asymmetry. Activity-specific metabolic equivalent values were used to
determine minutes per week of moderate and vigorous physical activity. RESULTS:
Future physical activity most strongly associated with baseline FoF (R = 0.09, P
< 0.01), and baseline FoF associated with limits of stability and lower extremity
strength asymmetry (R = 0.21, P < 0.001). Follow-up FoF is best predicted by
initial levels of FoF independent of intervening falls (beta = 3.26, P < 0.001).
CONCLUSIONS: Future physical activity of women with multiple sclerosis was best
predicted by FoF independent of physical and mental functioning. Increased FoF
was associated with greater lower extremity strength asymmetry and decreased
limits of stability rather than with the experience of falls.
