The cognitive timed up-and-go dual task (CogTUG) has been proposed to
improve the performance of the timed up-and-go (TUG) test for predicting falls in
older patients and as a screening tool for early detection of frailty. We aimed
to determine whether the CogTUG score is associated with a history of falls in
frail older outpatients with gait disorders.
This retrospective study
involved outpatients >75 years old with or without previous falls who were
admitted from 2012 to 2014 to a geriatric day hospital for gait disorders.
Patients took the TUG and CogTUG tests on the day of comprehensive geriatric
assessment. RESULTS: Among the 161 patients included (157 analyzed; mean age
84.4+/-6.2 years; 72% women), 84 (53.5%) had fallen in the previous year: 105
(66.9%) were considered pre-frail and 52 (33.1%) frail. As compared with
non-fallers, fallers had lower Tinetti balance scores (P=0.0004) and handgrip
strength (P=0.03), more lost weight (P=0.04), and they took longer to perform the
TUG test (P=0.04). Fallers and non-fallers did not differ in time taken to
perform the CogTUG test (30.7+/-11.2 vs. 28.5+/-10.2s, P=0.20). History of falls
was associated with only weight loss (odds ratio 3.43; 95% CI 1.13-11.30, P=0.03)
and handgrip strength (0.88; 0.78-0.97, P=0.02) on multivariate analysis.
CONCLUSION: Unlike TUG scores, the CogTUG score was not associated a history of
falls in frail older outpatients with gait disorders.
Our results underline that
weight loss and low muscle strength are related to falls.
