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.

Conditions

• Forward Head Posture
• Normal Head Posture

Interventions

Type	Name	Description
BEHAVIORAL	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.
