Arabic stance detection has attracted significant interest due to the growing importance of social media in shaping public opinion. However, the lack of comprehensive datasets has limited research progress in Arabic Natural Language Processing (NLP). To address this, we introduce ArabicStanceX, a novel and extensive Arabic stance detection dataset sourced from social media, comprising 14,477 tweets across 17 diverse topics. Utilizing the transformer-based MARBERTv2 model, we explore stance detection through Multi-Topic Single Model (MTSM) strategies, achieving a promising F1 score of 0.74 for detecting 'favor' and 'against' stances, and 0.67 overall. Our experiments highlight the model's capabilities and challenges, particularly in accurately classifying neutral stances and generalizing to unseen topics. Further investigations using zero-shot and few-shot learning demonstrate the model's adaptability to new contexts. This study significantly advances Arabic NLP, providing crucial resources and insights into stance detection methodologies and future research directions. The dataset is publicly available.

Functional recovery after total knee arthroplasty (TKA) varies widely among individuals, and traditional assessments often fail to detect subtle changes in real-world walking ability. Wearable sensors offer continuous and objective tracking of gait outside of clinical settings. In this prospective, longitudinal study, thirty-one patients undergoing unilateral TKA wore thigh-mounted accelerometers continuously from 2 weeks before surgery through 90 days postoperatively.

The Choroidal Vascularity Index (CVI), derived from optical coherence tomography (OCT), has emerged as a potential biomarker for detecting vascular changes. Understanding its variability across physiological states, ocular conditions, and systemic diseases is crucial for its integration into clinical practice. We evaluated variations in CVI across different physiological states (e.

Objectives: To investigate the association among 5 clinical functional performance tests-single-leg stance, gait speed, tandem gait, Timed Up and Go (TUG), and forward step- as indicators of functional decline in older adults, and to examine whether these associations vary across different age groups.
Design: Cross-sectional study.
Setting And Participants: Data were collected from 191 community-dwelling older adults, stratified into 4 age groups: 60-64, 65-69, 70-74, and 75-79 years.

Spinocerebellar ataxia (SCA) composite score (SCACOMS) is a statistically-derived composite measure comprising weighted items that are sensitive to change during early-stage disease. SCACOMS items and weights include the functional Scale for the Assessment and Rating of Ataxia Gait (12%), Stance (17%), Sitting (8%), and Speech (10%) items, and the Clinician Global Impression of Change (CGI) (53%). The content validity of SCACOMS is yet to be established.

Background: Mastoid vibration (MV) helps detect changes in spatial-temporal gait parameters and margin of stability, allowing researchers to study how sensory input influences motor control strategies. Additionally, ground reaction force (GRF) measurement has widely emerged as a more accessible alternative to camera-based motion capture systems for detecting balance control in healthy and pathological groups in smaller clinical settings.
Research Question: Would different MV affect the GRF parameters in healthy young individuals?
Methods: Twenty young adults experienced MV unilaterally or bilaterally during walking to temporarily disrupt vestibular function.
