Study population: Participants will be recruited from Samyook University(Seoul, South Korea) or local communities in Daegu or Seoul, South Korea. Recruitment will primarily target individuals who regularly engage in academic or sedentary activities. The study population will consist of individuals classified based on postural characteristics, specifically Forward Head Posture (FHP) or Normal Head Posture (NHP), assessed using craniovertebral angle (CVA) measurements. Recruitment will take place through campus advertisements, online postings, and word-of-mouth referrals.

Brief summary: * Recent studies have shown that individuals with forward head posture (FHP) experience not only impaired balance control but also cognitive deficits.
* 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: - This study is a cross-sectional study aiming to investigate the differences in balance ability between individuals with forward head posture (FHP) and those with normal head posture (NHP), as well as the differences in frontal lobe oxygenation levels during a balance-cognitive dual task.

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.

Eligibility criteria: Inclusion Criteria:

* Healthy adults aged 20 to 39 years
