Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Using a balance-cognitive dual-task paradigm, this study aims to explore the relationship between balance ability and Prefrontal cortex(PFC) oxygenation levels(△HbO2) in individuals with FHP compared to those with normal head posture(NHP).
* By analyzing differences in frontal lobe activation based on task difficulty, this study is expected to provide practical data for designing balance training and cognitive-motor intervention programs tailored to individuals with FHP.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study participants will be assigned to receive two groups: (a) Forward head posture (b) Normal head posture. Each group will perform three balance tasks while simultaneously completing three cognitive tasks. To determine the differences, the primary outcome will assess prefrontal cortex (PFC) hemodynamic response, and the secondary outcome will assess balance ability.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Forward head posture group
The experiment will be conducted for approximately 30 minutes. It will comprise cognitive tasks with three levels of difficulty and balance tasks, with task difficulty adjusted according to each participant's cognitive and balance abilities.
During the experiment, changes in cerebral blood flow, cognitive performance, and balance ability will be assessed and analyzed.
Cognitive-Balance dual task
The cognitive-balance dual task consists of three levels of difficulty and is performed simultaneously.
The cognitive tasks include the N-back test, while the balance tasks consist of static balance tasks.
Normal head posture group
The experiment will be conducted for approximately 30 minutes. It will comprise cognitive tasks with three levels of difficulty and balance tasks, with task difficulty adjusted according to each participant's cognitive and balance abilities.
During the experiment, changes in cerebral blood flow, cognitive performance, and balance ability will be assessed and analyzed.
