In this work, we developed 2D and 3D cell-based in vitro experimental models to visualize how cellular motions and stresses are correlated during aggregation and dissemination of cellular clusters. For quantitative analyses, we utilized particle image velocimetry (PIV), traction force microscopy (TF...
Trips occur when the foot strikes an obstacle during the swing phase of the gait cycle. The critical biomechanical variable associated with tripping risk is Minimum Foot Clearance (MFC). The pattern of toe trajectory in sagittal plane can be changed using different strategies to lift the foot which ...
The aim of this study was to compare hip and knee strength in asymptomatic active subjects with and without dynamic knee valgus (DKV). Sixty one active male subjects were evaluated, with DKV individuals (n=46) presenting weaker hip and knee strength compared to the group without DKV (n=15). No corre...
This abstract describes an automated, remotely deployable gait analysis technique that leverages machine learning and data from commercially available wearable sensors. The proposed technique is used to analyse gait in daily life for patients recovering from anterior cruciate ligament (ACL) reconstr...
In scientific studies and in commercial wearable devices it is often assumed that increases in ground reaction forces (GRF), or in GRF-correlated signals from pressure-sensing insoles and inertial measurement units (IMUs), indicates increases in musculoskeletal loading or overuse injury risk (e.g., ...
Using a Hill-type neuromuscular model we simulate squat jumps with different additional masses under the influence of different gravitational accelerations. Applying sensitivity analysis and the idea that training will improve the performance along the gradient of a performance function, we show the...
The implant failure for large defects is usually induced by unfavorable stress distribution due to unsuitable structural design in mandible reconstruction. Topology optimization is usually applied to solve structural optimization under one loading condition and cannot be applied to a specific mandib...
Background: Prospective authors are invited to submit manuscripts reporting original unpublished research and recent developments in the topics related to the conference. It is required that the manuscript follows the standard IEEE camera-ready format (IEEE standard format, double column, 10-point f...
To quantify functional recovery of total hip replacement patients following surgery, vertical ground reaction forces (vGRF: “return to full weight bearing”) may be used. However, its association with hip contact forces remains unclear. In this work it is shown that the vGRF impulse is the most r...
Dr. Wall-Scheffler is a biological anthropologist, who has made important contributions to the areas of locomotor evolution and behavioural ecology. Here she will discuss her work on how energy optimization shapes locomotion in reproductive females and its implications for human evolution.
Various types of cognitive challenges that may influence neuromuscular control may arise during athletic participation. We examined the effects of divided attention and memory challenges on knee loading during a jump landing task. Participants demonstrated less knee flexion when visual attention was...
We studied walking on a simulator designed for gaming where the subject moves by sliding his shoes on a concave surface. The metabolic cost is (about 3-5 times) higher compared with ‘normal’ walking and walking speed is lower than on treadmill at matched stride frequency. Total mechanical work i...
Wearable inertial sensors enable the measurement of human movement in non-laboratory environments. Because many sports movements cannot be accurately replicated inside a laboratory, inertial sensors (also known as inertial measurement units or IMUs) are one of the best tools for quantifying some of ...
Wearable sensors, which can be attached to the body for extended periods of time in real-world conditions, provide exciting new opportunities for biomechanics researchers to assess human movement. This session will present various research opportunities and challenges afforded by wearable technology...
Falls are common in people with multiple sclerosis (PwMS) and important predictors of experiencing a fall include fatigue and balance. While fatigue fluctuates, clinicians rely on self-report measures administered at discrete time points to assess fatigue and by extension, fall risk. Wearable inerti...
Children with Autism Spectrum Disorder (ASD) have demonstrated differences in gait mechanics when compared to children with neurotypical (NT) development. A common intervention used to address the negative behavior associated with ASD is a weighted vest (WV). Contemporary research has revealed that ...
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the ...
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...
Regular papers should present novel perspectives within the general scope of the conference. Short papers (Work-in-Progress) are an opportunity to present preliminary or interim results. Posters are intended for ongoing research projects, concrete realizations, or industrial applications/projects pr...
Now, there is increasing concern that inaction by some of Silicon Valley's most important companies risks destabilizing the global economy. Those worries, drawn into focus by recent live-fire drills conducted by the Chinese military in waters surrounding Taiwan, have prompted dire warnings from Whit...
Non-invasive brain stimulation techniques are typically applied at rest, but may be more effective or representative of neural changes when applied during a range of voluntary effort. We investigated the effect of voluntary drive on intracortical facilitation (ICF), short-interval intracortical inhi...
Active workstation use has been shown to decrease sedentary behavior in the workplace. However, a dual-task environment creates a division of focus increasing the risk of an adverse gait-related event. The current study examined lower extremity (LE) tripping descriptors during a difficult precision ...
The accuracy of wearable sensors for measuring kinematics during return-to-play testing has not been established. This study compared a commercially available wearable sensor system to video motion analysis for six different activities. There was generally good agreement between the two systems, wit...
A lot of wearable sensor technologies have been developed and applied in sports. Many sports teams notice that wearable technology is helpful for improving performance, reducing injuries and enhancing fan experience. Wearables will more develop along with sensor technology. It is also important to p...
We investigated the influence of an American football helmet on axial loading at the cervical spine during low-velocity impacts at eight impact locations to a Hybrid III headform. Compared to bare head impacts, the football helmet condition frequently resulted in increased axial loads at the cervica...
Balance control during quiet standing of patients with neurogenic claudication (NC) was less stable than healthy adults. However, the weighting of the sensory systems was not different between patients with NC and healthy adults. Therefore, other factors such as motor output systems should be determ...
Maximal (average) mechanical power output during cycling is constrained by many (bio-)mechanical factors. Here, we set out to find the maximal power that can be produced by the muscles of the lower limb during a fully constrained periodic movement. We used a musculoskeletal model capable of matching...
Movement is critical to both our cognitive and physical health. As our lifestyles have become more sedentary, running has become one of the most popular ways to remain fit. Unfortunately, running injuries are common with 30-40% of runners becoming injured in a given year. With nearly 60 million Amer...
