velocidad de la marcha y la independiente la
edad, el sexo, los psicofármacos adecuados
e inadecuados.
Resultados
: En el modelo
multivariante ajustado por edad (B = 0,025,
p<0,001) y sexo (ser hombre B = 0,226 y p
= 0,047), los sujetos que tomaban psicofár-
macos inadecuados tenían medias de veloci-
dad de la marcha disminuidas en 0,1 m/seg
(B= 0,114, p=0,040) respecto los que no los
tomaban, sin embargo los sujetos que to-
maban psicofármacos adecuados no tenían
cambios estadísticamente significativos en
las medias de su velocidad de la marcha (B=
0,023, p=0,672).
Conclusiones
: Este estudio
es un análisis preliminar, que abre una nue-
va línea de investigación. Los sujetos que
tomaban psicofármacos inadecuados tenían
medías de velocidad de la marcha clínica y
estadísticamente inferiores que los que no
los tomaban. Sin embargo, en las personas
que tomaban psicofármacos adecuados no
presentaban cambios estadísticamente sig-
nificativos. Dada la alta prevalencia de en-
fermedad ansiosa depresiva en las personas
mayores, sería conveniente realizar nuevos
estudios para comprobar si a las personas que
tomaban psicofármacos inadecuados y tienen
problemas en la estabilidad de su marcha, si
al cambiarles a un psicofármaco adecuado
ven disminuida dicha inestabilidad.
Palabras clave:

Abstract
The factors that modify gait are those that
have been classically identified as risk fac-
tors for falls and their treatment is one of
the bases for preventing falls and improving
gait stability. The speed of walking has pro-
ven to be a good predictor of falls. Physical
exercise, the reduction of polypharmacy and
the withdrawal of psychotropic drugs are
common in the treatment of gait instabili-
ties. However, in daily clinical practice due
to the high prevalence of affective disorders
and anxiety in the elderly, the withdrawal
of psychotropic drugs is not always possi-
ble. On the other hand, when talking about
drugs in older people there are well-defined
criteria that categorize drugs according
to their pharmacokinetic characteristics
in inadequate and appropriate, but when
analysing psychotropic drugs and walking,
there are few articles that make the distinc-
tion between appropriate and inadequate
psychotropic drugs.
The aim of this study
is to analyse whether subjects who take
inappropriate psychotropic drugs have lower
gait speeds of subjects who take appropria-
te psychotropic drugs and those who do
not.
Methods
: Cross-sectional observational
study. 120 people were selected with inde-
pendent march, free of disability. Exclusion
criteria were mental or physical disability,
diseases that could modify the gait, acute
illness in the last 6 months or poor short-
term prognosis. The speed of the march was
released measured at 6 meters. The statisti-
cal analysis was a linear regression, the de-
pendent variable was the speed of the march
and the independent age, sex, the appro-
priate and inadequate psychotropic drugs.
Results
: In the multivariate model adjusted
for age (B = 0.025, p <0.001) and sex (being
male B = 0.226 and p = 0.047), the subjects
taking inappropriate psychotropic drugs had
gait speed averages decreased by 0.1 m /
sec (B = 0.114, p = 0.040) with respect to
those who did not take them; however, the
subjects who took adequate psychotropic
drugs did not have statistically significant
changes in the means of their gait speed (B
