Effectiveness of an Innovative Therapeutic Exercise Program on Physical and Cognitive Function in Mild Cognitive Impairment Due to Alzheimer's Disease

Kinematic and kinetic gait assessment

时间窗: baseline, post- intervention (12 weeks)

Participants will be instructed to walk at their self-selected, comfortable walking pace. Gait performance will be assessed under four task conditions: single-task walking, dual-task walking, single-task obstacle crossing, and dual-task obstacle crossing. These conditions are designed to evaluate participants' walking ability and adaptability under both simple and cognitively demanding circumstances. Duration: ≈ 40 minutes

Functional Gait Assessment (FGA)

时间窗: baseline, post- intervention (12 weeks)

The Functional Gait Assessment is a clinical tool used to evaluate postural stability during various walking tasks. The assessment includes 10 standardized walking tasks, each addressing a distinct aspect of gait and balance. Performance on each task is rated on a 4-point ordinal scale (0-3), where higher scores indicate better functional performance. The total score ranges from 0 to 30, with a higher total score representing normal gait and balance, and a lower score indicating gait instability or impaired functional mobility. Test duration: ≈ 10-15 minutes

mini Balance Evaluation Systems Test (mini-BESTest)

时间窗: baseline, post- intervention (12 weeks)

The Mini-BESTest is a clinical balance assessment tool designed to evaluate dynamic balance control and identify the specific balance systems affected in individuals with balance disorders. It is a shortened version of the original Balance Evaluation Systems Test (BESTest). It comprises 14 items, each scored on a 3-point ordinal scale (0-2), with a maximum total score of 28 points. The assessment includes four subscales, each representing a specific component of balance control: Anticipatory Postural Adjustments - maximum score: 6 points Reactive Postural Control - maximum score: 6 points Sensory Orientation - maximum score: 6 points Dynamic Gait - maximum score: 10 points Higher scores indicate better balance performance, while lower scores reflect greater balance impairment. Test duration: ≈ 15minutes

Montreal Cognitive Assessment (MoCA)

时间窗: baseline, post- intervention (12 weeks)

The MoCA assesses global cognitive function across multiple domains. It includes 12 brief tasks, grouped into 7 cognitive domains: Total possible score: 30 points. Each task contributes a set number of points according to its complexity. If the individual has ≤ 12 years of education, 1 additional point is added to the total score to account for educational effects. Higher score indicates better global cognition while lower scores indicate impairment Administration time: ≈ 10-15 minutes

Cognitive Telephone Screening Instrument (COGTEL)

时间窗: baseline, post- intervention (12 weeks)

The test consists of six subtests, each targeting a specific cognitive domain: 1. Prospective Memory:(Score range: 0-2 points) 2. Verbal Short-Term Memory: (Score range: 0-8 points) 3. Verbal Long-Term Memory : (Score range: 0-8 points) 4. Working Memory (Backward Digit Span): (Score range: 0-12 points) 5. Verbal Fluency: (Score = number of correct words produced) 6. Inductive Reasoning: (Score range: 0-8 points) Each subtest yields an individual score, which are combined into a total composite score using a weighted formula reflecting the relative contribution of each domain to overall cognition: Total COGTEL score =(7.2 × Prospective Memory) + (1.0 × Verbal Short-Term Memory) + (0.9 × Verbal Long-Term Memory) + (0.8 × Working Memory) + (0.2 × Verbal Fluency) + (1.7 × Inductive Reasoning) Higher score indicates better cognitive performance while lower scores indicate impairment Administration time: ≈ 10-15 minutes

Stroop Test

时间窗: baseline, post- intervention (12 weeks)

The Stroop test is a sensitive index of executive function and attention. During the task, the participant is required to name the color of the ink in which a word is printed rather than read the word itself. Total number of correct responses within a set time limit (60 seconds), and number of errors (including self-corrections and uncorrected errors) are calculated. Higher scores indicate better executive control, while lower or negative scores suggest difficulty inhibiting automatic responses. Administration time: ≈5-10 minutes
