Interrelationships of Depression, Pain, and Gait Mechanics and their Associations with Physical Activity Levels Among People with Knee Osteoarthritis
Background/Purpose: Depression is associated with low physical activity (PA) levels in people with knee osteoarthritis (KOA)1. Pain contributes to both depression and PA levels in…Abstract Number: 0769 • ACR Convergence 2025
Increased Gait Variability at Preferred Walking Speeds is Associated with Increased Physical Activity Measures in People with Knee Osteoarthritis
Background/Purpose: People with knee osteoarthritis (OA) often exhibit reduced physical activity levels and increased fall risk. Gait variability, specifically center of mass (COM) variability is…Abstract Number: 1940 • ACR Convergence 2025
Correlation of Hand and Lymphatic Function Post Exercise Intervention in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease which often leads to deformities and loss of function of hands. Despite the availability of…Abstract Number: 1612 • ACR Convergence 2025
Window of opportunity with tocilizumab therapy in giant cell arteritis. Multicenter study of 471 patients of clinical practice
Background/Purpose: Tocilizumab (TCZ) is the only biological drug currently approved for the treatment of giant cell arteritis (GCA), regardless of GCA duration. The “window of…Abstract Number: 1188 • ACR Convergence 2025
Aortic Wall Shear Stress May Be a Protective Factor Against Development of Spinal Osteoproliferation
Background/Purpose: Diffuse idiopathic skeletal hyperostosis (DISH) is often characterized by new bone formation along the right anterolateral spinal column, particularly in the thoracic region (1,…Abstract Number: 0701 • ACR Convergence 2024
Diagnostic Performances of Vascular Biomarkers Soluble Fms-like Tyrosine Kinase (sFlt-1) and Placental Growth Factor (PlGF) in Scleroderma Renal Crisis: A Case Control Study
Background/Purpose: Scleroderma renal crisis (SRC) is a major vascular complication of systemic sclerosis (SSc), associated with high morbidity and mortality. Few biomarkers are available to predict…Abstract Number: 1175 • ACR Convergence 2024
Physical Activity and Symmetry Following Total Knee Arthroplasty:Results of an Exploratory Trial
Background/Purpose: Studies have identified two key deficits in individuals’ activity-related trajectories following total knee arthroplasty (TKA). First, overall physical activity (PA) levels remain very low.…Abstract Number: 0312 • ACR Convergence 2023
Frontal Lobe Activation and Gait Alterations During Single- and Dual-task Walking in People with Knee Osteoarthritis: A Functional Near-infrared Spectroscopy Study
Background/Purpose: Altered gait patterns, including high variability or muscular co-contraction, can increase fall risk and worsen disease progression in people with knee osteoarthritis (OA). However,…Abstract Number: 0846 • ACR Convergence 2023
Preosteoclast Plays a Pathogenic Role in Syndesmophyte Formation of Ankylosing Spondylitis Through the Secreted PDGFB – GRB2/ERK/RUNX2 Pathway
Background/Purpose: Ankylosing spondylitis (AS) is a chronic inflammatory disease that mainly affects the sacroiliac joint and spine. However, the real mechanisms of immune cells acting…Abstract Number: 1184 • ACR Convergence 2023
A Wearable-Sensor for Assessment of Gait and Chair Stand Patterns in People with Knee Osteoarthritis: Validation and Responsiveness to Treatment of a Potential Digital Biomarker
Background/Purpose: The objectives of this study in people with knee osteoarthritis (OA) were to (a) examine the agreement between measures of gait and chair stand…Abstract Number: 1193 • ACR Convergence 2023
The Association of Peak Forces and Loading Rates During Walking with MRI-Based Structural Worsening of the Knee: The Multicenter Osteoarthritis Study
Background/Purpose: Mechanical loading is an important, modifiable risk factor for knee osteoarthritis (OA). Walking loads have been previously proposed as a risk factor for developing…Abstract Number: 1293 • ACR Convergence 2023
Single Camera Hand Motion Capturing as a Digital Biomarker for Disease Activity in Rheumatoid Arthritis Using Computer Vision: The Proof-of-Concept MeFisto Study
Background/Purpose: Computer vision technology offerspromising possibilities for remotely assessing disease activity in rheumatoid arthritis (RA) patients, enabling telemedicine and improving access to care. The objective…Abstract Number: 2106 • ACR Convergence 2023
Evaluation of the Construct of Constitutional Stiffness (CS) in Anti-CCP-Antibody-Positive Rheumatoid Arthritis (ACPA+RA) and Controls
Background/Purpose: The risk of developing ACPA+RA, predictors of severity and causes of excess cardiovascular disease (CVD) are incompletely understood. We have observed that RA patients…
