ROLE OF DUAL-TASK COST IN PREDICTING FALL RISK AMONG OLDER ADULTS RECEIVING INSTITUTIONAL CARE

Condition(s) studied

Study summary

There is a need for studies that examine the role of dual-task cost in predicting fall risk among older adults receiving institutional care and that develop classification models that can be used in clinical practice. The planned study aims to determine the discriminative ability of dual-task cost in identifying fall risk and to establish clinically meaningful cutoff values. In this respect, the study will both contribute to a more sensitive assessment of fall risk and provide a scientific basis for a low-cost, practical, and applicable screening approach.

Eligibility

Primary outcome measure(s)

• Clinical Information Form — Single assessment (baseline)
  The following participant information will be recorded using a clinical information form developed by the researcher: Age (years) Sex (male/female) Educational status(illitirate/primare education/secondary education/high school or higher) Length of institutional stay( months and years) Height(cm) Weight(kg) Body mass index BMI (kg/m²) Number of chronic diseases and comorbidities Number of daily medications Use of assistive devices
• Fall Assesment — Single assessment (baseline)
  Fall history (Tripping, Slipping, Loss of Balance, Transposition) Fall History Questionnaire A fall will be defined as an event which results in an individual coming to rest inadvertently on the ground, floor, or a lower level. In this context, the following information will be recorded: Presence of a fall within the last 12 months (yes/no) Total number of falls within the last 12 months Presence of a fall within the last month (yes/no) Primary cause of the last fall Location of the last fall Injury status resulting from the last fall
• Montreal Cognitive Assessment (MoCA) — Single assessment (baseline)
  This assessment will be utilized to determine whether participants possess the cognitive competence to understand and execute the study protocol. Individuals with a MoCA score below 18 will be excluded from the study.
• Timed Up and Go Test (TUG) — Single assessment (baseline)
  This test will be utilized to assess the functional mobility of the participants. The participant will be instructed to rise from a standard-height chair, walk a distance of 3 meters, turn around, return to the chair, and sit back down. The duration of the test will be recorded in seconds.
• Dual-task Timed Up and Go Test (TUG-DT) — Single assessment (baseline)
  This test will be administered to evaluate the dual-task performance of the participants. Participants will be instructed to simultaneously perform a cognitive task during the TUG test. Cognitive Task Animal naming will be utilized as the cognitive task under the dual-task condition. The participant will be asked to name as many animals as possible while walking. All participants will be assigned the same task, and standard verbal instructions will be utilized.
• Dual-Task Cost (DTC) — Single assessment (baseline)
  The dual-task cost will be calculated using the single-task TUG and dual-task TUG durations according to the following formula: DTC (%)"=(TUG\_DT-TUG)/TUG×100 An increase in the DTC percentage will indicate greater performance degradation under the dual-task condition.
• Tinetti Performance-Oriented Mobility Assessment (POMA) — Single assessment (baseline)
  This assessment will be utilized to evaluate the balance and gait performance of the participants. The total Tinetti score will be used to determine the risk of falls. Operational Definition of Fall Risk Fall risk will be operationalized in two ways in the study: As a continuous variable: Total Tinetti score As a binary classification variable: Risk group based on the Tinetti score Classification based on the Tinetti score will be structured as follows: Low fall risk: 25-28 points Increased fall risk: 24 points and below This binary classification will be utilized for the classification model and ROC analysis.
• Falls Efficacy Scale-International (FES-I) — Single assessment (baseline)
  This scale will be utilized to assess the participants' level of fear of falling as a descriptive and secondary variable. The FES-I score will not serve as a primary variable in the main model; however, it will be reported in descriptive analyses and secondary analyses as required.
