Publication Open Access The influence of artificial breast volume induction on postural stability, postural orientation, and neuromuscular control in healthy Women: A cross-sectional study2025-01-09 - Guedes, Diana C.; Carneiro, Daniela F.; Alves, Leonel A. T.; Melo, Ana S. C.; Moreira, Juliana; Cunha, Bruno; Santos, Rubim; Noites, Andreia; Sousa, Andreia S. P.(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 the immediate changes in postural control after artificial breast augmentation in healthy female volunteers. (2) Methods: Spinal angles, the center of pressure (CoP), and electromyographic activity of the spinal muscles were recorded in the static position and during the functional reach test (FRT) without and with implants of different volumes (220 mL, 315 mL, and 365 mL). Subjective perceptions of effort, comfort, weight, and performance in the FRT were also assessed. (3) Results: Statistical differences were significant in the scapular elevator during the one-minute standing position (lower activation with the 220 mL implant compared to the control and 315 mL) and in the trapezius muscles during the FRT (lower activation in the upper trapezius in the 315 mL vs. control in the reach phase and 220 mL vs. control in the return phase and higher activation in the lower trapezius in the 315 and 365 mL vs. control in the reach phase). Additionally, significant differences were identified in the performance of the FRT and the associated subjective perceptions. (4) Conclusions: Breast implants with sizes of 220, 315, and 365 mL can alter scapular neuromuscular control, but these differences do not seem substantial enough to result in negative biomechanical effects in the short-term analysis.Publication Restricted Access Providing informative feedback in a low-cost rehabilitation system using machine learning2024-11-14 - Rodrigues, Paul; Amorim, Ivone; Cunha, BrunoRehabilitation is a core process in helping people recover from a wide range of health issues, including injuries and diseases. Although advancements in technology and the use of artificial intelligence have facilitated the development of tools to aid in rehabilitation processes, there is a lack of low-cost solutions that patients, without requiring advanced care, can use at home. In this work, we propose a low-cost intelligent system for lower limb rehabilitation that uses machine learning to provide informative feedback to users. Compared to existing solutions, our system offers the advantage of real-time feedback, informing patients whether they are performing exercises correctly. It also suggests posture corrections to prevent injuries and accelerate the recovery process. Moreover, our system can be used at home on a smartphone, tablet, or personal computer, and does not require patients to purchase additional devices, which is a significant benefit. The system includes four exercises: Squat, Romanian Deadlift, Glute Bridge, and Donkey Kick. Validation tests with end-users reinforced the usability of this system and confirmed the importance of real-time feedback. The results were also useful for identifying areas for improvement, particularly with the Squat exercise, which is among the more challenging exercises to perform correctly.Publication Open Access Kinematic and kinetic gait principal component domains in older adults with and without functional disability: A cross-sectional study2025-04-23 - 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 domains differentiate those without and with functional disability. Methods: Through a cross-sectional design, older adults aged 60 and over (n = 35 without and n = 25 with functional disability) were analyzed during overground gait. A principal component analysis (PCA) was used to determine principal components from gait parameters previously demonstrated to express age-related effects (spatiotemporal parameters, sagittal ankle moment and power, ground reaction forces peak, and tridimensional lower limb joints range of motion and positions at heel strike and toe-off). Results: Pace, variability, propulsion, hip and knee control, transverse ankle control, asymmetry, sagittal ankle control, frontal ankle control, frontal hip control, and pre-swing control domains explained 83.90% of the total gait variance in older adults. pace and frontal hip control distinguished individuals with disabilities. Conclusions: PCA identified ten gait domains in older adults. Pace and frontal hip control distinguished disabilities, revealing cautious walking patterns and weaker hip abductor strength.Publication Open Access Kinematic Biomarkers of Functional Disability in Older Adults: Analysis of the Timed Up and Go Test2025-09-19 - 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 potential for wearable sensor applications. Sixty adults aged 60+ participated in this cross-sectional study. Three-dimensional lower limb and trunk range of motion (ROM), velocity, center of mass (CoM) displacement, and velocity were analyzed using an optoelectronic system across TUG subphases: sit-to-walk, walk-forward, turn, walk-back, and turn-to-sit. Principal component analysis identified eleven principal components (PCs), explaining 84.33% of the total variance. PCs included sagittal hip and knee motion and CoM velocity during turn-to-sit and walking (PC1); tri-dimensional trunk velocity during turning, walk-back, and sit-to-walk transitions (PC2, PC4, PC6); sagittal knee and hip velocity in sit-to-walk (PC3); and frontal and transverse plane knee ROM and velocity during turning (PC5). Significant differences between functional disability groups were found for PC1 and PC4. These findings provide benchmark data for developing and validating wearable biosensors aimed at monitoring kinematic biomarkers.Publication Open Access Sit-to-stand and stand-to-sit kinematics in older adults with and without functional disability: A principal component analysis2025-09-02 - 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 mass (CoM) acceleration, postural sway and principal component (PC) scores for each task. Principal component models (PCMs) included lower limb and trunk tridimensional joint ranges of motion, angular velocity range, CoM displacement and velocity along each Sit-TS (flexion, momentum transfer, extension and stabilisation) and Stand-TS (initiation, flexion, momentum transfer and extension) phases. Results Older adults with functional disability exhibited increased Sit-TS peak antero-posterior CoM acceleration (p = .02). The Sit-TS and Stand-TS PCMs included nine PCs each. In Sit-TS, the first three explained half the variance: PC1 captured transverse hip and knee stabilisation kinematics, PC2 described trunk and hip frontal and transverse control during flexion, and PC3 represented sagittal knee and ankle control during momentum transfer and extension. In Stand-TS, variance was more distributed (PC1 describing frontal hip and knee flexion velocity, PC2 sagittal trunk and hip extension velocity, and PC3 vertical CoM velocity at extension). Significant group differences emerged in PC4 (transverse knee and frontal hip kinematics) and PC9 (sagittal and frontal trunk angular velocity ranges during momentum transfer). Conclusions Both transitions revealed distinct joint and trunk control demands. Principal components involving transverse knee, frontal hip and trunk angular velocities distinguished disability groups, with Stand-TS showing greater discriminative power.Publication Open Access Smartphone-Based Markerless Motion Capture for Accessible Rehabilitation: A Computer Vision Study2025-09-02 - Cunha, Bruno; Maçães, José; Amorim, IvonePhysical rehabilitation is crucial for injury recovery, offering pain relief and faster healing. However, traditional methods rely heavily on in-person professional feedback, which can be time-consuming, expensive, and prone to human error, limiting accessibility and effectiveness. As a result, patients are often encouraged to perform exercises at home; however, due to the lack of professional guidance, motivation dwindles and adherence becomes a challenge. To address this, this paper proposes a smartphone-based solution that enables patients to receive exercise feedback independently. This paper reviews current Computer Vision systems for assessing rehabilitation exercises and introduces an intelligent system designed to assist patients in their recovery. Our proposed system uses motion tracking based on Computer Vision, analyzing videos recorded with a smartphone. With accessibility as a priority, the system is evaluated against the advanced Qualysis Motion Capture System using a dataset labeled by expert physicians. The framework focuses on human pose detection and movement quality assessment, aiming to reduce recovery times, minimize human error, and make rehabilitation more accessible. This proof-of-concept study was conducted as a pilot evaluation involving 15 participants, consistent with earlier work in the field, and serves to assess feasibility before scaling to larger datasets. This innovative approach has the potential to transform rehabilitation, providing accurate feedback and support to patients without the need for in-person supervision or specialized equipment.
