- Functional ability and independence among older adults in Northern Portugal: A cross-sectional studyPublication . Moreira, Juliana; Santos, Rubim; Sousa, Andreia S. P.; Santos Moreira, Juliana; Rubim Silva Santos, Manuel; Pinheiro de Sousa, Andreia SofiaThe aging process impacts daily living activities, highlighting the need to assess functional ability to support independence in older adults. To characterize the functional ability of community-dwelling older adults in northern Portugal. Methodology: Sixty older adults, aged 60 and above, were assessed for body composition, self-reported health, medication intake, and fall history. Independence in basic and instrumental daily activities was evaluated using the Barthel Index and Lawton and Brody scale, respectively. Functional tests included handgrip strength, 10 meters walk test, five-times sit-to-stand, Timed up and go test, and one leg standing test. Participants had an average age of 67.86±6.46 years, classified as pre-obese based on body mass index, 43.95±6.77 kilograms of muscle mass, and 30% of body fat. Over half (51.6%) rated their health as poor, 88.3% took prescribed medication (average of three per day), and 36.7% had fallen in the past year. Dependence was observed in daily activities (Barthel Index: 19.86±0.35; Lawton and Brody: 22.70±1.23). Functional tests revealed a handgrip strength of 27.39±8.56 kilograms (37.21±6.06 for males, and 22.50±3.93 for females), a self-selected gait velocity of 1.78±0.19 meters/second, a time to complete the five-times sit-to-stand, the Timed up and Go and the one leg standing of 15.48±3.71, 9.32±1.99 and 30.23±23.07 seconds, respectively. While older adults in northern Portugal demonstrate mild functional impairments, their challenges in daily activities and self-perceived health from age 60 underscore the importance of early intervention strategies. Further research is needed to identify influencing factors and develop targeted interventions to enhance independence.
- Sit-to-stand and stand-to-sit kinematics in older adults with and without functional disability: A principal component analysisPublication . Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.; Rubim Silva Santos, Manuel; Pinheiro de Sousa, Andreia Sofia; Santos Moreira, JulianaSit- to-Stand (Sit- TS) and Stand-to-Sit (Stand- TS) transitions are essential daily movements affected by ageing and disability. This study aimed toexplore related kinematic domains in older adults with and without disability. A cross-sectional study including adults aged 60 years or older, with(n = 25) and without disability (n = 35). Comparisons between groups includedtask time, centre of mass (CoM) acceleration, postural sway and principal com-ponent (PC) scores for each task. Principal component models (PCMs) includedlower limb and trunk tridimensional joint ranges of motion, angular velocityrange, CoM displacement and velocity along each Sit-TS (flexion, momentumtransfer, extension and stabilisation) and Stand-TS (initiation, flexion, momen-tum transfer and extension) phases. Older adults with functional disability exhibited increased Sit-TS peakantero-posterior CoM acceleration (p = .02). The Sit-TS and Stand-TS PCMs in-cluded nine PCs each. In Sit-TS, the first three explained half the variance: PC1captured transverse hip and knee stabilisation kinematics, PC2 described trunkand hip frontal and transverse control during flexion, and PC3 represented sagittalknee and ankle control during momentum transfer and extension. In Stand-TS,variance was more distributed (PC1 describing frontal hip and knee flexion ve-locity, PC2 sagittal trunk and hip extension velocity, and PC3 vertical CoM veloc-ity at extension). Significant group differences emerged in PC4 (transverse kneeand frontal hip kinematics) and PC9 (sagittal and frontal trunk angular velocityranges during momentum transfer). Both transitions revealed distinct joint and trunk control de-mands. Principal components involving transverse knee, frontal hip and trunkangular velocities distinguished disability groups, with Stand-TS showing greaterdiscriminative power.
