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
