Association of Wearable-Sensor Derived Gait Measures with Widespread Pain over 2 Years: A Machine Learning Analysis in the Multicenter Osteoarthritis Study
Background/Purpose: Gait patterns can put stress on the back and weight bearing joints and can even affect upper extremity joints. Walking involves muscle activation and…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: 1974 • ACR Convergence 2023
Comparison of Gait Spatiotemporal Measures Between Patients with Insertional Achilles Tendinopathy or Midportion Achilles Tendinopathy
Background/Purpose: Insertional and midportion Achilles tendinopathy (AT) are painful injuries affecting both active and sedentary populations. Patients with AT present with pain with loading, often…Abstract Number: 0504 • ACR Convergence 2022
Three-dimensional Ground Reaction Force Symmetry Metrics Largely Fail to Explain Cartilage Worsening in the Contralateral Knee in Persons with Unilateral Knee Osteoarthritis: The Multicenter Osteoarthritis Study
Background/Purpose: Knee osteoarthritis (KOA) often starts as a unilateral disease and commonly progresses to bilateral KOA. There is a need to identify mechanisms that explain…Abstract Number: 0839 • ACR Convergence 2022
Association of Tibial Acceleration During Walking to Knee Pain and Loading in Adults with Knee Osteoarthritis
Background/Purpose: Pain and abnormal loading are known to be associated with the progression of knee osteoarthritis (OA). Individuals with knee OA have increased vertical loading…Abstract Number: 0847 • ACR Convergence 2022
Association of Frontal Plane Trunk Motion During Gait with Abductor Strength, Fatigue, and Physical Activity in Women with Hip Osteoarthritis
Background/Purpose: We have previously reported that fatigue and hip abductor weakness are associated with reduced physical activity (PA) in women with hip osteoarthritis (OA). We…Abstract Number: 0970 • ACR Convergence 2022
Influence of Sociodemographic and Clinical Features on Ground Reaction Force Variability Among Individuals with Symptomatic Knee Osteoarthritis: A Novel Computational Approach
Background/Purpose: Abnormally applied forces across the knee during walking play a central role in knee osteoarthritis (OA) disease pathways. Biomechanical data collected continuously during gait…Abstract Number: 1784 • ACR Convergence 2022
Gait Alterations Associated with Worsening Physical Function over 2 Years: A Machine-learning Approach in the Multicenter Osteoarthritis (MOST) Study
Background/Purpose: Altered gait is related to pathogenesis of knee osteoarthritis (OA). For people with knee OA, in addition to pain, declines in physical function are…Abstract Number: 1910 • ACR Convergence 2022
Evaluation of Dynamic Effects of Depressive Symptoms on Functional Outcomes in Knee Osteoarthritis
Background/Purpose: Knee OA is a leading cause of functional decline, and psychiatric comorbidity is common, particularly major depression. Depressive symptoms decrease physical activity and exacerbate…Abstract Number: 1920 • ACR Convergence 2022
Gait and Physical Activity Predictors of Knee Replacement: A Machine Learning Analysis in the Multicenter Osteoarthritis Study
Background/Purpose: Rates of knee replacement (KR) due to knee osteoarthritis (OA) are rising exponentially and currently no interventions prevent KR. Gait and physical activity are…Abstract Number: 0210 • ACR Convergence 2021
Using Machine Learning to Predict Medial Knee Cartilage Worsening over 2 Years Using Gait and Physical Activity: The MOST Study
Background/Purpose: Identifying knees at risk of worsening osteoarthritis (OA) could help to identify individuals in need of interventions. While gait and physical activity are considered…Abstract Number: 1586 • ACR Convergence 2021
Individuals with Pre-arthritic Hip Pain Walk with Hip Motion Alteration Common in Individuals with Hip OA
Background/Purpose: Individuals with hip osteoarthritis (OA) commonly walk with less hip extension compared to individuals without hip OA. This alteration is often attributed to walking…Abstract Number: 1902 • ACR Convergence 2021
Gait Alterations Associated with Worsening Knee Pain over 2 Years: A Machine-learning Approach in the MultiCenter Osteoarthritis Study
Background/Purpose: Altered gait is related to structural worsening of knee osteoarthritis (OA). However, it is not known if altered gait is associated with increased risk…Abstract Number: 0322 • ACR Convergence 2020
Development and Preliminary Validation of Smartphone Sensor-based Measurement Tools for Psoriatic Arthritis
Background/Purpose: The COVID-19 pandemic has increasingly driven clinical care into remote settings, where patients with immune-mediated and inflammatory diseases struggle to convey symptom severity to…Abstract Number: 0565 • ACR Convergence 2020
In Those with Unilateral Frequent Knee Pain, Between-Limb Differences in Stance Time During Walking Increase the Risk of Frequent Pain in the Other Knee: The MOST Study
Background/Purpose: Knee osteoarthritis (OA) commonly begins as a unilateral disease, with pain in only one knee. Yet 88% of persons with unilateral knee OA develop…
