Dynamic Compression of Articular Cartilage Explants Increases Formation and Decreases Degradation of Type II Collagen
Background/Purpose: Mechanical loading is recognized as a major factor in initiation and progression of osteoarthritis (OA). Conversely loading is believed to play an essential role…Abstract Number: 2765 • 2017 ACR/ARHP Annual Meeting
Centre of Pressure Characteristics during Walking in Individuals with and without First Metatarsophalangeal Joint Osteoarthritis
Background/Purpose: Osteoarthritis of the first metatarsophalangeal joint (1st MTPJ OA) is a common and disabling condition characterised by symptoms of joint pain and stiffness, formation of…Abstract Number: 652 • 2017 ACR/ARHP Annual Meeting
Investigating the Role of Mechanical Stress in Spondyloarthritis Pathogenesis
Background/Purpose: Mechanotransduction is a cell’s ability to translate mechanical stimuli into biochemical signals and has been implicated in signaling pathways involving differentiation and proliferation. Mechanical…Abstract Number: 2185 • 2017 ACR/ARHP Annual Meeting
Relation of Foot Pronation to Medial Knee Load in Persons with Medial Knee Osteoarthritis
Background/Purpose: The knee adduction moment (KAM) estimates medial knee load during gait, with high KAM fueling worsening OA. Understanding how foot mechanics contribute to KAM…Abstract Number: 291 • 2016 ACR/ARHP Annual Meeting
Relation of Foot Pronation during Walking to Risk of Worsening Lateral Patellofemoral and Medial Tibiofemoral Cartilage Damage
Background/Purpose: Foot pronation can lead to lateral patellofemoral (PF) maltracking with reduced tibiofemoral (TF) varum, inciting speculation that the highly pronated foot reported in knees…Abstract Number: 359 • 2016 ACR/ARHP Annual Meeting
The Association of Scheuermann’s Disease with Osteoporotic Vertebral Fracture Risk
Background/Purpose: Scheuermann’s disease is one of the most frequent illnesses of the spine in teenagers. Its evolution over time is poorly understood. Spinal deformities, by…Abstract Number: 1307 • 2016 ACR/ARHP Annual Meeting
Anatomical Patterns Suggest the Involvement of Biomechanical Stress in the Pathogenesis of Erosions in Rheumatoid Arthritis
Background/Purpose: There is limited data outlining the anatomic characteristics of bone erosions of the small joints in rheumatoid arthritis (RA). In particular, there is minimal…Abstract Number: 1005 • 2015 ACR/ARHP Annual Meeting
Association of Baseline Knee Sagittal Dynamic Joint Stiffness during Gait and 2-Year Cartilage Damage Progression in Knee Osteoarthritis (OA)
Background/Purpose: While patellofemoral (PF) OA has been found to have substantial impact on pain and function, most studies continue to focus on tibiofemoral (TF)…Abstract Number: 2389 • 2015 ACR/ARHP Annual Meeting
Relation of Pronated Foot Posture to Risk of Worsening Knee Pain during Gait and Compartment-Specific Knee Cartilage Damage
Background/Purpose: Pronated foot posture is prevalent in older adults with knee cartilage damage and younger adults with knee pain. Yet, there is disagreement about the…Abstract Number: 2390 • 2015 ACR/ARHP Annual Meeting
Foot Kinematics and Foot Center of Pressure and Their Association with Medial Knee Load Reduction with Use of Flexible Shoes in Knee Osteoarthritis
Background/Purpose: Biomechanical treatments for medial knee osteoarthritis (OA) often target the knee adduction moment (KAM). Foot-mediated biomechanical interventions for knee OA may operate through altering…Abstract Number: 2945 • 2014 ACR/ARHP Annual Meeting
Foot Structure and Function Show Associations with Lower Extremity Physical Function
Background/Purpose . Foot pain is associated with poorer physical function in older adults, but few studies have examined how foot structure (high / low arches) and…Abstract Number: 2861 • 2014 ACR/ARHP Annual Meeting
Changes in Knee Kinematics from a 6-Week Hip and Trunk Strengthening Program for Persons with Patellofemoral Osteoarthritis
Background/Purpose: Patellofemoral (PF) osteoarthritis (OA) is prevalent in middle-aged adults. Aberrant lower extremity (LE) biomechanics is one etiology of knee OA. Reduced peak knee flexion…Abstract Number: 2245 • 2014 ACR/ARHP Annual Meeting
Characteristics of Conventional Footwear and Their Association with Reductions in Knee Loading with a Flexible Footwear Intervention
Background/Purpose: The peak external knee adduction moment (KAM) as measured through gait analyses has been associated with severity, progression and pain in medial knee osteoarthritis (OA);…Abstract Number: 973 • 2014 ACR/ARHP Annual Meeting
Relation of Pelvic Drop during Walking to Risk of Incident Medial Knee Osteoarthritis: The Multicenter Osteoarthritis Study
Background/Purpose: During walking, the contralateral pelvis tends to drop as the weight bearing limb enters midstance. If excessive, pelvic drop (PD) can result in increased…Abstract Number: 212 • 2014 ACR/ARHP Annual Meeting
Relation of Shoe Stability to Risk of Knee Cartilage Damage: The Multicenter Osteoarthritis Study
Background/Purpose: Clinical guidelines recommend that “every patient with knee osteoarthritis should receive advice concerning appropriate footwear”, yet the recommended content of this advice is not…
