Validity and reliability of a tool for accelerometric assessment of static balance in women
Sammanfattning
Purpose: The aim of this study was to identify factors of balance and items explaining each of them
and then, using a model based on accelerometric variables, to develop an easy-to-apply tool for assessing
static balance.
Materials and methods: A descriptive and cross-sectional study was carried out in a random sample
of 145 adult women (63.8 ± 8.4 years). Participants performed the following randomised tests of static
equilibrium tests: monopodal balance with eyes closed; bipodal balance on mat with eyes open; bipodal
balance with eyes closed; monopodal balance with eyes open and monopodal balance on mat
with eyes closed. Each test was performed three times and an average calculated.
Results: The resulting scale had three factors: monopodal balance on mat with eyes open, with four
items; monopodal balance with eyes open, with four items; monopodal balance with eyes closed, with
three items.
Conclusions: This tool is easy to apply and analyse, and presents good criterion validity for explaining
the state of static balance based on the accelerations of the centre of mass.
