Introduction. Sit-to-stand (SitTS) and stand-to-sit (StandTS) are very important functional tasks that become compromised in stroke patients. As other voluntary movements, they require an adequate postural control (PC) involving the generation of anticipatory adjustments (APAs). In order to give clues for more efficient directed rehabilitation programs, a deeper knowledge about APAs during challenging daily life movements is essential.
Despite extensive research on chronic ankle instability, the findings regarding proprioception have been conflicting and focused only injured limb. Also, different components of evaluated in isolation. To evaluate bilateral individuals with unilateral instability. Cohort study. Research laboratory center a university. Twenty-four history sprain instability (mechanical group, n = 10; functional [FAI] 14) 20 controls. Ankle active passive joint position sense, kinesthesia, force sense. We...
(1) Background: The percentage of breast augmentations has increased in recent years alongside the frequency implant removals. Musculoskeletal and postural disorders are often overlooked during this removal process. Research indicates that excess anterior load from implants can disrupt control potentially lead to short- or long-term musculoskeletal dysfunction. This study aims evaluate immediate changes after artificial augmentation healthy female volunteers. (2) Methods: Spinal angles,...
This study aimed to evaluate the laboratory cultivation of Chondracanthus acicularis, focusing on key environmental parameters such as nutrient levels and light exposure. The results provide insights into optimal growth conditions biochemical composition C. which are crucial for its sustainable exploitation in industrial applications. Significant differences relative rate (RGR) productivity (Y) were found between different treatments. Seaweed grown Provasoli (PES) Medium with white LED red...
To analyse the relationship between traditional stiffness and muscle antagonist coactivation in both stroke healthy participants, using linear non-linear measures of COP during standing, stand-to-sit, gait initiation. Participants were evaluated through a cross-sectional design. Electromyography, isokinetic dynamometer, force plate used to calculate coactivation, intrinsic functional stiffness, displacement, with metrics. Spearman's correlations Mann-Whitney tests applied (p < 0.05)....
Objectives: Gait kinematic and kinetic changes have been identified in older adults, highlighting the need to explore principal age-related components how these are associated with functional disability. This study aims perform a factor analysis, including gait parameters adults establish determinant domains. Additionally, this identify which domains differentiate those without Methods: Through cross-sectional design, aged 60 over (n = 35 n 25 disability) were analyzed during overground...
This study aims to assess the influence of gait speed (manipulated through cadence) on muscle activity patterns and activation degree during stance. Methods: Thirtyfive healthy individuals participated in this study. Surface electromyographic from gastrocnemius medialis (GM), gluteus maximus (GMax), biceps femoris (BF) rectus (RF) was acquired with subjects walking at three different speeds. Results: Speed influenced: (1) relative motor heel strike, midstance-propulsion transition...
Shoulder rehabilitation is a process that requires physical therapy sessions to recover the mobility of affected limbs. However, these are often limited by availability and cost specialized technicians, as well patient’s travel session locations. This paper presents novel smartphone-based approach using pose estimation algorithm evaluate quality movements provide feedback, allowing patients perform autonomous recovery sessions. reviews state art in wearable devices camera-based systems for...
Introduction: Atypical ankle patterns of muscle activity during gait are commonly reported in patients with stroke. These findings can be due to changes between tibialis anterior (TA) and soleus (SOL) coactivation mechanisms.Objective: To compare the electromyographic (EMGa) SOL TA muscles antagonist (C) level contralateral (CONTRA) ipsilateral (IPSI) limbs side stroke lesion stance phase cycle.Methods: Twelve subjects a episode participated this study. The signal ground reaction forces were...
Muscle stiffness had a crucial role in joint stability, particularly, at the shoulder complex. Although changes upper trapezius muscle have been described for pain, contradictory findings obtained. Also, existing data regarding scapular muscles are, majorly, about trapezius. Myotonometry is method used to assess stiffness; however, reliability values of through this not assessed pain conditions. The present study aims compare muscles’ (trapezius, serratus anterior, and levator scapulae)...
Despite the existence of several studies about scapula’s position and motion, in shoulder pain conditions, there are still conflicting findings regarding scapular adaptations reduced research role during functional tasks. The present study aimed to compare scapular-related kinematic electromyographic outcomes different movements (with without load) drinking task, between symptomatic asymptomatic subjects. Forty subjects (divided into two groups) participated this cross-sectional...
This paper presents a new computational framework for automatic foot classification from digital plantar pressure images. It classifies the as left or right and simultaneously calculates two well-known footprint indices: Cavanagh's arch index (AI) modified AI. The accuracy of was evaluated using set images common pedobarographic devices. results were outstanding, all feet under analysis correctly classified no significant differences observed between indices calculated solution traditional...
