The Pittsburgh Sleep Quality Index (PSQI) will assess subjective sleep quality, using a validated Chinese version. Previous research has demonstrated good internal consistency reliability (0.82) and 14- to 21-day test-retest reliability (0.85) of the PSQI Chinese version in Taiwan's populations. Each component score of the PSQI ranges from 0 to 3, with 3 indicating the greatest dysfunction or disturbance. The seven component scores are then summed to obtain a global PSQI score, which ranges from 0 to 21. Higher scores indicate poorer sleep quality, with a score greater than 5 suggesting significant sleep difficulties.

The Godin-Shephard Leisure Time Physical Activity Questionnaire (GLTPA) will measure weekly physical activity intensity, classified into light, moderate, and vigorous levels. The Chinese version of the GLTPA has shown good validity and is significantly correlated with mental health outcomes. By classifying physical activity intensity lasting for more than 15 minutes in the past week into strenuous activities, moderate strenuous activities, and light activities, and then multiplying by corresponding coefficients 9, 5, and 3 respectively for quantification, the sum of these scores is Godin's leisure time physical Total activity score, with higher scores indicating greater physical activity. The level of physical activity can be divided into three levels according to the total Godin leisure time physical activity score. A total score of 24 or above is considered active, a score between 14 and 23 is moderately active, and a score below 14 is consider Insufficiently active.

Cognitive function will be assessed pre-enrollment using the MMSE, with validated age- and education-adjusted thresholds. The MMSE has demonstrated good reliability and validity and is a strong predictor of disability levels in patients with traumatic brain injury. Participants with an MMSE score below 24 will be excluded from the study to ensure appropriate cognitive capacity for participation. The score range is 0-30 points, with the international standard cut-off value of 24 points, 18-24 points as mild dementia, 16-17 points as moderate dementia, and ≦15 points as severe dementia.

The Montreal Cognitive Assessment (MoCA) is a sensitive tool for the early screening of mild cognitive impairment, particularly useful for detecting deficits in executive function, attention, short-term memory, language fluency, abstract thinking, and visuospatial abilities. The total score of the scale is 30 points, with a score of less than 26 considered indicative of possible mild cognitive impairment. The score can be adjusted (+1 point) based on educational level. The Chinese version of MoCA has been proven to have good reliability and validity (Cronbach's α = 0.83) and is particularly suitable for research populations in Asian regions.

In this study, the Biolight MediTECH® near-infrared brain blood flow imaging sensor (hemoencephalography; HEG) was used to measure blood flow in the prefrontal cortex. The Biolight near-infrared spectroscopy device is an HEG sensor designed by MediTECH®, based on NIR technology to observe the optical properties of cells and tissues at the reflection level. This enables monitoring of changes in oxyhemoglobin and deoxyhemoglobin concentrations. By measuring light absorption at different wavelengths, the system can continuously track changes during tissue oxidation processes, thereby measuring cerebral blood flow conditions. The percentage of the NIR brain blood flow ranged 0- 100%, the higher percentage means the higher prefrontal brain blood flow.

Preliminary findings from this study applied the cardiac metabolic performance benchmark (CMPB3) to compare the effectiveness of increasing cerebral blood circulation at different intensities (CMPB3 ≤ 35, 40, 45, 50). Results indicated that CMPB3 levels above 40 effectively increased cerebral blood circulation, with improvements observed not only during exercise but also during the post-exercise rest period, where cerebral blood flow remained higher than the baseline level. The lower intensity means the lower exercise intensity and the higher ability to perform aerobic walking exercise. The benchmark will be calculated by the Heart rate measured by Garmin fitness bracelet.

This study will adopt semi-structured interviews to gain an in-depth understanding of participants' experiences and perceptions of the walking program, as well as to complement and interpret quantitative data.

It is a qualitative data, not a quantitative data.

The interview content covers three major themes:

1. Benefits of the walking program;
2. Experiences and challenges of the walking program;
3. The impact of the walking program on quality of life, sleep quality, concussion symptoms, psychological resilience, depression, exercise motivation, exercise self-efficacy, and physical activity.

Garmin Vivosmart 5. This wearable device will track heart rate, exercise frequency, exercise duration, exercise intensity, step count, and sleep data. Data will be integrated with the Garmin Connect app for real-time monitoring and feedback. A preliminary study conducted by our research team in 2020 showed a high correlation (r = 0.91) between heart rate measurements obtained from the Garmin Vivosmart and the Zephyr BioHarness, supporting its use for home-based heart rate monitoring. Participants will wear the device at home to facilitate real-time tracking of exercise intensity and physiological responses during the intervention. Advanced sleep tracking in compatible Garmin devices incorporates multiple factors to provide information on sleep patterns. In addition to basic information, such as sleep onset and wake-up time, researchers will be able to obtain data on periods of wakefulness and time spent in key sleep stages, including light, deep, and rapid eye movement (REM) sleep.
