OBJECTIVE To compare the differential effect of custom orthoses on the lower extremity mechanics of a forefoot and rearfoot strike pattern. DESIGN Fifteen subjects ran with both a forefoot and a rearfoot strike pattern with and without orthoses. Lower extremity kinematic and kinetic variables were compared between strike pattern and orthotic conditions. BACKGROUND Foot orthoses have been sh...

OBJECTIVES Foot orthoses are commonly used in the management of knee OA, although the relationship between foot function and knee OA is still unclear. The purpose of the study was to examine foot function during walking in people with and without medial compartment knee OA. METHODS Motion of the tibia, rearfoot and forefoot in 32 patients with medial compartment knee OA and 28 age-matched con...

BACKGROUND Knee osteoarthritis is a musculoskeletal condition which is most prevalent in the medial compartment. This injury causes considerable pain, disability, and negative changes in kinetic and kinematic parameters. The efficiency of unloader valgus brace as a conservative treatment for medial knee osteoarthritis is not well documented. OBJECTIVES The aim of this study was to review the ...

BACKGROUND Arthrogryposis Multiplex Congenita (AMC) is a heterogeneous condition characterized by multiple joint contractures at birth. Greater movements in the trunk and pelvis during walking have been observed in children with AMC using orthoses compared to those wearing only shoes. This study investigated gait dynamics in children with AMC and identified compensatory mechanisms that accommod...

PURPOSE There is emerging evidence that foot orthoses are effective in the management of patellofemoral pain syndrome (PFPS). However, the identification of those most likely to benefit from foot orthoses has not been adequately explored. The aim of this study was to develop a preliminary clinical prediction rule to help identify individuals with PFPS who are most likely to benefit from foot or...

We investigated the immediate effects of a varus knee brace on knee symptoms and knee-joint biomechanics in an individual with predominant lateral tibiofemoral joint osteoarthritis (TFJOA) and valgus malalignment after anterior cruciate ligament (ACL) reconstruction. A varus unloader brace was prescribed to a 48-year-old male with predominant lateral radiographic and symptomatic TFJOA and valgu...

Using three soft-tissue analogs of variable compliances, four custom functional knee orthoses were evaluated for their abilities to control anterior tibial displacement (ATD) using an anterior cruciate ligament (ACL)-deficient surrogate knee model with applied forces from 25 to 250 N. These analogs had stiffnesses (compliance) ranging from 2.18 N/mm to 4.6 N/mm, simulating the range in the thig...
