The computer-assisted cognitive rehabilitation: The computer-assisted cognitive rehabilitation intervention will be conducted via the RehaCom (Hasomed, Germany) platform. The intervention program is designed to include combinations of modules targeting selective and divided attention, executive functions, processing speed, and visuospatial perception, with each session lasting 40 minutes. It will be implemented in a stepwise manner, with content and difficulty levels gradually increasing every two weeks.

Study summary

The aim of this study is to conduct a comparative analysis of the effects of two different rehabilitation approaches on cognitive and functional outcomes in older adults diagnosed with mild cognitive impairment (MCI).

The study compares two widely used approaches in the field of cognitive rehabilitation: Computer-Based Cognitive Rehabilitation (CBCR) and Dual-Task Training (DTT).

The planned study will be conducted using a randomized controlled, parallel-group experimental design, in which individuals aged 65 and older diagnosed with MCI will be assigned to two intervention groups via computer-assisted randomization. Both groups will receive training for eight weeks, twice a week for 45 minutes each session, under the supervision of a specialist physical therapist. Pre- and post-intervention assessments will measure general cognitive function, executive function, fall risk, dual-task performance, functional independence, fear of falling, and physical activity level.

This study is based on the assumption that cognitive decline is not limited to neuropsychological performance alone but is closely related to motor performance, safe mobility, and quality of life. The findings are expected to contribute to clinical decision-making processes by providing evidence-based data on which rehabilitation approach is more effective and feasible for older adults with HBB.

Eligibility

Primary outcome measure(s)

• Mini Mental State Examination — baseline and at the end of the 8-week intervention
  The Mini-Mental State Examination (MMSE) is a 30-point, 5-10 minute questionnaire used to screen for cognitive impairment, covering orientation, memory, and attention. A score of 25-30 is considered normal, while scores below 24 may indicate impairment, making it crucial for detecting dementia in clinical settings.
• The Trail Making Test — baseline and at the end of the 8-week intervention
  The Trail Making Test (TMT) is a common neuropsychological test measuring cognitive flexibility, processing speed, and executive functioning through two parts. Part A requires drawing lines to connect 25 numbered circles in ascending order. Part B requires alternating between numbers and letters (1-A, 2-B, etc.) in ascending order, evaluating the ability to switch between tasks.
• The Timed Up And Go Test — baseline and at the end of the 8-week intervention
  The Timed Up and Go (TUG) test is a simple, quick assessment of functional mobility, balance, and fall risk in older adults or those with mobility conditions. It measures the time it takes for an individual to stand from a chair, walk 3 meters (10 feet), turn around, walk back, and sit down.
• The Timed Up and Go dual-task Test — baseline and at the end of the 8-week intervention
  The Timed Up and Go (TUG) dual-task test is a clinical assessment that combines the standard TUG mobility test with a simultaneous cognitive task. This method helps evaluate a person's ability to maintain balance and mobility while performing another activity, which is a common real-life scenario.
