About this trial
Both aging and Parkinson's disease (PD) negatively affect postural control and increase the risk of falls, with frontal plane balance being particularly challenging for these populations. While previous studies have mainly focused on sagittal plane balance, the contribution of hip abductor muscles remains unclear, especially regarding their force production and control abilities. Therefore, this study aims to investigate hip abductor muscle force production and force control, and to examine whether these factors are associated with postural control, gait, and balance performance in individuals across different ages and those with PD.
