About this study
UDDGait™ is a multidisciplinary research project with the overreaching goal of providing an aid for early identification of cognitive impairment and risk of dementia development, thereby providing a basis for adequate symptom relieving and health promoting interventions.
A new concept is investigated for this purpose: a "dual-task-test", which implies the combination of a well-established mobility test (Timed Up-and-Go, TUG) with a simultaneous verbal task (i.e. TUG dual-task, TUGdt). This type of test has been judged as a potential aid for early identification of dementia disease. More research is needed to further examine the test's validity, reliability and predictive capacity.
The overall aim is to investigate if TUGdt is useful as an aid for prediction of dementia disease. To ensure the results, the aim is also to evaluate the test's measurement properties and to generate normative reference values of healthy control persons.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Timed Up-and-Go (TUG single-task)Diagnostic test
The TUG test is a well-established clinical test of one mobility sequence: rising from an armchair, walking straight ahead, passing a line marked on the floor, turning around, walking back, and sitting down again.
Timed Up-and-Go dual-task (TUGdt)Diagnostic test
Two dual-task tests including TUG (TUGdt) were carried out: TUGdt naming animals and TUGdt months backwards. The outcomes registered were: time scores for TUG single-task and both TUGdt tests, TUGdt costs (relative time difference between TUG single-task and TUGdt), number of different animals named, number of months recited in correct order, number of animals per 10 s, and number of months per 10 s.
Clinical functional assessmentDiagnostic test
The diagnostic procedure was part of the clinical routine for patients undergoing memory assessment and involved a geriatrician's careful evaluation of the patient's history and cognitive testing including Mini-Mental State Examination (MMSE), Clock Drawing Test, Verbal Fluency Test, and Trail Making Test A and B. In addition, all participants carried out short versions of the Geriatric Depression Scale and the General Motor Function Assessment Scale, as well as static balance according to the Bohannon Method, and hand grip strength using a dynamometer.

What is being measured
The primary outcome is the main question the study is designed to answer.
Conversion to dementia
Diagnostic information for follow-ups and eventual dates of death, all participants' medical records will be reviewed by an experienced geriatrician. Participants will be classified as having "converted" after receiving a dementia diagnosis, and as "not converted" when a diagnosis of Subjective or Mild cognitive impairment had been confirmed after baseline, or when a reversion to normal cognition had been stated.
TUG and TUGdt parameters and composite indices will be examined for association with dementia incidence through Cox regression models with and without adjustment for possible confounding variables such as age, gender, and education. Possible occurrence of gender differences in associations between TUG parameters and dementia incidence will be examined. Optimal cut-off values for predictive TUG parameters (including composite indices) will be estimated. Also, sensitivity, specificity, c-statistics, and Youden's J index will be estimated.
Measured: Upp to 10 years
Secondary outcomes (1)
Level of cognitive functioning
Similarly to TUG and TUGdt parameters, association between different cognitive test results and dementia incidence through Cox regression models with and without adjustment for possible confounding variables such as age, gender, and education will be examined.
Measured: Upp to 10 years

UDDGait™ is a multidisciplinary research project with the overreaching goal of providing an aid for early identification of cognitive impairment and risk of dementia development, thereby providing a basis for adequate symptom relieving and health promoting interventions.
A new concept is investigated for this purpose: a "dual-task-test", which implies the combination of a well-established mobility test (Timed Up-and-Go, TUG) with a simultaneous verbal task (i.e. TUG dual-task, TUGdt). This type of test has been judged as a potential aid for early identification of dementia disease. More research is needed to further examine the test's validity, reliability and predictive capacity.
The overall aim is to investigate if TUGdt is useful as an aid for prediction of dementia disease. To ensure the results, the aim is also to evaluate the test's measurement properties and to generate normative reference values of healthy control persons.

Questions about this trial
What is this clinical trial studying?
An observational study of Dementia and Dementia, Mixed, run by Dalarna University at 2 sites in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 12 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Anna Cristina Åberg, PhD (+4623778082, aab@du.se), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Conversion to dementia (time frame: Upp to 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05893524, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2025.
