Kinematic and kinetic gait principal component domains in older adults with and...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objectives: Gait kinematic and kinetic changes have been identified in older adults, highlighting the need to explore the principal age-related components and how these are associated with functional disability. This study aims to perform a factor analysis, including gait kinematic and kinetic parameters in older adults to establish determinant gait domains. Additionally, this study aims to identify which domai...
The influence of artificial breast volume induction on postural stability, post...
Guedes, Diana C.; Carneiro, Daniela F.; Alves, Leonel A. T.; Melo, Ana S. C.; Moreira, Juliana; Cunha, Bruno; Santos, Rubim; Noites, Andreia(1) Background: The percentage of breast augmentations has increased in recent years alongside the frequency of implant removals. Musculoskeletal and postural disorders are often overlooked during this removal process. Research indicates that excess anterior load from breast implants can disrupt postural control and potentially lead to short- or long-term musculoskeletal dysfunction. This study aims to evaluate...

Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objective Sit-to-Stand (Sit-TS) and Stand-to-Sit (Stand-TS) transitions are essential daily movements affected by ageing and disability. This study aimed to explore related kinematic domains in older adults with and without disability. Methods A cross-sectional study including adults aged 60 years or older, with (n = 25) and without disability (n = 35). Comparisons between groups included task time, centre of m...
Kinematic Biomarkers of Functional Disability in Older Adults: Analysis of the ...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.The Timed Up and Go (TUG) test is used to assess mobility in older adults, but its reliance on completion time limits its insight into detailed movement patterns that could serve as early indicators of functional decline. This study aimed to identify lower limb and trunk kinematic biomarkers during the TUG test that distinguish between older adults with and without functional disability, emphasizing the potenti...
Principal component analysis of stair negotiation and floor transition kinemati...
Moreira, Juliana; Teles, Ivone da Silva; Cunha, Bruno; Félix, José; Guedes, Diana C.; Alves, Leonel A. T.; Santos, Rubim; Sousa, Andreia S PStair negotiation (ascending and descending) and transitions to level walking are complex motor tasks influenced by aging; yet the impact of functional disability on these changes remains underexplored. This study aimed to evaluate the lower limb joint positions, velocities, and the center of mass (CoM) displacement and velocity during stair negotiation and transitions in older adults with and without functiona...

Association between the history of fall and the fear of falling on stair descen...
Teles, Ivone; Moreira, Juliana; Sousa, Andreia S. P.; Santos Moreira, Juliana; Pinheiro de Sousa, Andreia SofiaAmong older adults, there is a high incidence of history of fall (HoF), fear of falling (FoF), and falls on stair descent during gait transitions. We aim to evaluate the association between HoF and FoF on spatiotemporal and lower-limb kinematic parameters in older adults during stair descents and gait transitions. Sixty older adults (>60 years) were evaluated through an optoelectrical motion capture system duri...
Association between gait lower limb intra and interlimb coordination and fear o...
Castro, Márcia; Moreira, Juliana; Sousa, Andreia S. P.; Santos Moreira, Juliana; Pinheiro de Sousa, Andreia SofiaAging often leads to a decline in intersegmental coordination, particularly in the lower limbs, which can negatively impact gait stability and symmetry. While fear of falling (FoF) and a history of falls (HoF) increase fall risk in older adults, their relationship with intra- and intersegmental coordination during gait remains understudied. This cross-sectional observational study involved 60 participants aged ...
