Arthrogenic muscle inhibition (AMI) after ACL reconstruction is a result from neural inhibition and quadriceps muscle atrophy. Asymmetrical quadriceps muscle strength has also been reported after ACLR and is associated with altered biomechanics during dynamic movement tasks. It is currently unknown ...

Current measures of growth plate shape are limited to 2D. However, bone growth is a 3D process and methods for measuring 3D growth plate changes are critical for understanding direction of bone growth. This research presents a method for quantifying 3D growth plate shape to assess differences betwee...

Modern CT devices now allow 3D geometrical measurements on the foot under load, finally giving access to the overall bone architecture in weight bearing. Previous measures were limited either by the 2D projection implied in the X-ray radiograms, or by the non-weight-bearing standard CT scans in supi...

We present a novel multiscale modelling approach for investigating knee joint tissue mechanics during dynamic activities. Based on a musculoskeletal model with 12 degrees of freedom (DOF) knee joint (tibiofemoral and patellofemoral joints), muscle forces, knee joint contact forces and moments, and t...

The Spanish squat targets the knee extensors and has been suggested to be an appropriate rehabilitation exercise for debilitative knee conditions. This study provides novel empirical data on the effect of trunk inclination on the demands of the Spanish squat that has application on the progression a...

This short presentation provides a few thoughts on how the field of biomechanics has evolved over my career, the role of the Canadian Society for Biomechanics (CSB) in my career development and thoughts on how the field will continue to contribute to addressing important clinical questions that can ...

Forward somersault movements (FSMs) are very often used in gymnastics beam competitions. FSMs include four different movements (A, B, C, D) with increasingly difficulties. Twenty-one movements (9 A, 8 B, 3 C, 1 D) performed by national or international level gymnasts were recorded using high speed v...

The purpose of this study was to compare elderly faller classifications using pressure mat and force parameters as input to machine learning algorithms. Balance and gait were assessed using pressure mat and force plate data in 59 non-fallers (NF) and 41 fallers (F). Biomechanical parameters included...

Finite element modeling can be used to evaluate the effects of altered loading conditions on the knee joint stresses, and thus to predict possible failure locations. The aim was to generate finite element models of ACL reconstructed patients (n = 5) with relatively simple soft tissue materials to id...

On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty ...

The purpose of the study was to verify the specificity of the proximal-distal sequence of the jump throw in handball. This phenomenon was observed from three different perspectives: (1) the sequence of the maximal linear velocities of the joints and ball, (2) the sequence of the initiation of the mo...

Although weightbearing CT scans have become common for assessment of foot and ankle disorders, radiographs are still the standard for imaging the hindfoot. This study assessed the influence of various digitally reconstructed radiograph (DRR) projection views derived from weightbearing CT scans with ...

This study aims to design a three-dimensional computational model to simulate walking for both able-bodied individuals and prosthesis users. The inverse dynamics model is driven using able-bodied gait kinematics. The model calculates the muscle forces required to produce the measured kinematics, bot...

The results when managing displaced humeral greater tuberosity fractures through conservative means are often disappointing. This biomechanical study, using porcine models, compares fixation of these fractures with locking plate, bridging suture and two-screws to determine which is the strongest, an...

Extensive research goes into developing assistive technology that can replicate biological function after severe lower limb trauma. The assistive technology we put on a patient can be most advantageous when we also invest in what we put in a patient. Considering the needs and challenges of the end u...

We compared different devices (Force Plate {FP}, Inertial Measurement Units {IMU}, Pen-tail {Pen}) across related metrics of postural sway for the Clinical Test of Sensory Interaction and Balance (CTSIB).We found that Area of Ellipse Bounded (AoE B) and AoE eigenvalue (AoE E) were the most sensitive...

The Upper Quarter Y Balance Test (YBT-UQ) is a closed-chain upper extremity (UE) test that allows clinicians to assess unilateral UE function in the reaching and the stabilizing limb. There are several aspects of the YBT-UQ that have been studied (reliability, validity, correlations to other functio...

Trunk reaction time and three-dimensional trunk-hip motions were compared between subjects with and without chronic low back pain (LBP). The control group demonstrated greater trunk flexion; however, the LBP group reduced trunk flexion to protect against further injuries following the novelty of the...

Pathomechanics of diabetic foot ulceration has been largely investigated by plantar loading measurements, and recently also by human motion analyses [1]. Rarely medical imaging has been used, because this is static, and also radiograms are in 2D, and standard CT scans are performed in supine, i.e. i...

Spatio-temporal evolution of joint space width (JSW) during motion is of great importance to help with early treatment plans for degenerative joint diseases like osteoarthritis (OA). However, only a few studies have attempted to quantify the JSW from moving joints and the accuracy of measurements al...

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarr...

A better understanding of contact kinematics of the shoulder joint after total shoulder arthroplasty (TSA) may help identify causes of poor clinical outcomes following surgery [1]. In-vivo glenohumeral (GH) joint kinematics can be quantified from biplane fluoroscopic images using a 2D-3D image regis...

In orthopaedic surgeries, evaluation and treatment planning are highly based on empirical evidence and clinical expertise of each surgeon. Furthermore, inter-subject anatomical variation is hardly considered in decision-making. Therefore, the aim of this study was to create a clinically applicable p...

Wearable instruments for gait analysis offer new opportunities to study human motion during activities of daily living (ADL). Previous work has overlooked the importance of characterizing non-steady state ADL such as sit-to-stand, gait initiation/termination and turning using wearables. The purpose ...

To determine the feasibility of utilizing gyroscopic data to differentiate common gait perturbations, we compared the resultant angular velocities measured with optical motion capture (OMC) and Inertial Measurement Units (IMUs) in the feet and shank during running. The systems were tested under 4 di...

This study aims to compare the regional load transfer forces of consecutive steps between typically developed children and children with congenital talipes equinovarus (CTEV or clubfoot).

The human masticatory region is a highly complex biomechanical apparatus. A connection between joint problems and increased joint loads has been suggested in previous literature, but in vivo investigations of the joint load are not possible. Biomechanical computer simulation remains one of the only ...
