Article
Full-text available
Torsional deformities of the femur and tibia are associated with gait impairments and joint pain. Several studies have investigated these gait deviations in children with cerebral palsy. However, relatively little is known about gait deviations in children with idiopathic torsion and debate ensues about the management of these patients. Research q...
Article
Full-text available
Hip rotation during gait is a major indicator for femoral derotation osteotomy. However, repeatability of hip rotation is poor because of discrepancies in determining the medial-lateral axis of the femur. Combining 3D gait analysis with medical imaging allows in vivo evaluation of current clinical methods. We used the condylar axis, identified from...
Article
Hip rotation from gait analysis informs clinical decisions regarding correct of femoral torsional deformities. However, it is among the least repeatable due to discrepancies in determining the medial-lateral axis of the femur. Conventional or functional calibration methods may be used to define the axis but there is no benchmark to evaluate these m...
Article
Full-text available
Ultrasound imaging is relatively inexpensive, does not involve ionising radiation, and requires much shorter scan times compared with other imaging modalities such as magnetic resonance imaging and computed tomography. These advantages make it an appealing option in both clinical and research settings. Computational models of the human musculoskele...
Article
Full-text available
Background and Objectives: Ambulant children with cerebral palsy can demonstrate persistent “foot drop” after successful gastrocsoleus lengthening (GSL) surgery for equinus deformity. This may be due to inadequate strength and/or selective motor control of the ankle dorsiflexor muscles. A procedure has been developed to reduce foot drop—Tibialis An...
Article
Background Torsional deformities of the lower limbs in children and adolescents are a common cause of in-toeing gait and cause gait deviations. The purpose of this study was to examine the relationship of children and adolescents with suspected Idiopathic Torsional Deformities(ITD) and pain, gait function, activity and participation. Methods A ret...
Article
Full-text available
Background and Objectives: Equinus is the most common deformity in children with cerebral palsy, and surgical lengthening of the gastrocsoleus muscle-tendon unit is the most commonly performed operation for children with cerebral palsy. Treatment outcomes of orthopaedic surgery can be measured objectively with three-dimensional gait analysis. This...
Conference Paper
Introduction: Kinematics and kinetics during gait are used to inform surgical decision making. For example, hip rotation kinematics are considered the key measurement to decide to perform a femoral derotational osteotomy, and to predict surgical outcomes [1]. However, the accuracy and reliability of hip rotation kinematics has been shown to be the...
Article
Full-text available
Measurement of gait kinematic variability provides relevant clinical information in certain conditions affecting the neuromotor control of movement. In this article, we present a measure of overall gait kinematic variability, GaitSD, based on combination of waveforms' standard deviation. The waveform standard deviation is the common numerator in es...
Article
Full-text available
Despite variation in bone geometry, muscle and joint function is often investigated using generic musculoskeletal models. Patient-specific bone geometry can be obtained from computerised tomography, which involves ionising radiation, or magnetic resonance imaging (MRI), which is costly and time consuming. Freehand 3-D ultrasound provides an alterna...
Conference Paper
Full-text available
Inaccurate identification of the knee joint axis leads to cross-talk and influences the hip rotation profile. The influence on hip rotation is particularly important when utilised to assess patients for de-rotation osteotomies. No gold standard exists for defining the knee axis making it difficult to evaluate previous methods. Initially the knee ax...
Article
Full-text available
Slipped capital femoral epiphysis is known to produce characteristic deformities in the proximal femur, which affect hip motion and may cause a limp. This paper assessed the 3D gait kinematics in adolescents after single screw fixation of moderate to severe, stable, unilateral slipped capital femoral epiphysis. Our goals were to characterize the 3D...
Conference Paper
The ability to measure foot plantar pressure and gait characteristics during a prolonged period of daily life activities has many important applications in people with gait disorders. This paper presents the development of a wearable textile sensor sock incorporating these measurements, offering the potential to detect major events during the stanc...
Article
In children with spastic diplegia, surgery for ankle equinus contracture is associated with a high prevalence of both overcorrection, which may result in a calcaneal deformity and crouch gait, and recurrent equinus contracture, which may require revision surgery. We sought to determine if conservative surgery for equinus gait, in the context of mul...
Article
Full-text available
Multilevel orthopaedic surgery may improve gait in Type IV hemiplegia, but it is not known if proximal femoral osteotomy combined with adductor release as part of multilevel surgery in patients with hip dysplasia improves hip development. We asked whether varus derotational osteotomy of the proximal femur, combined with adductor release, influenced...
