The purpose of this project was to determine how countermovement jump performance variables change as a function of skill level in basketball, by comparing them between male high school athletes, NBA draft picks, and professional basketball players. Our findings suggest that greater jump height is f...
With recent developments in the resolution with which spine skin-surface motion is tracked, the opportunity presented itself to calculate the effects of creep deformation on spine motion during manual lifting across smaller sub-regions of the lumbar spine. Study results demonstrated that lumbar spin...
We evaluated the Pneumatic Ergonomic Crutch (PEC), which consisted of a pneumatically-activated sleeve orthosis worn to improve wrist posture and loading when using a Lofstrand crutch. A spring-loaded piston pump at the PEC crutch tip was used to harvest pneumatic energy for pressuring the orthosis ...
Afferent inputs of cutaneous sensitivity (CS) are essential for the control of movements. Motor control is affected already in early stages of dementia, but CS had not yet been studied. We investigated CS at the foot and hand in MCI subjects compared to controls. We only found gender differences for...
Acceleration measures may be collected for entire training sessions in real-world conditions using wearable sensors. The resulting data must be reduced to provide meaningful metrics. The aims of this study were to: (1) quantify the influence of binning methods on a cumulative damage metric based on ...
t is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable Engl...
Inertial measurement units (IMUs) are one of the most practical alternatives to optoelectronic systems for human motion analysis. Their low price, flexibility, and ease of use make them highly attractive, as they promise to facilitate out-of-clinic patient monitoring and therapy for a wide range of ...
The prime method of analyzing gait cycles with balance aiding devices has typically been restricted to laboratory controlled environments, where motion capture software or visual observation are available. Few methods for real-world gait analysis exist that do not require active human monitoring. We...
One premise underlying the use of home-based neurogames is that motion data collected through gaming sensors in the field (i.e., Microsoft KinectTM) accurately represent client outcomes. We evaluate that premise through secondary analysis of kinematic data from a federally-funded project in which a ...
Cosimulation of glenohumeral dynamics employing contact at the glenohumeral interface predicted glenohumeral head displacements during shoulder elevation similar to those reported in cadaveric studies.
This study explored whether player position in baseball influenced countermovement jumping strategies and their resultant force-time profiles. Subjects performed a series of three countermovement jumps on a force platform. Eccentric rate of force development (RFD), peak concentric force, countermove...
This study identified compensation strategies in ACLR athletes that persisted across 3 unilateral landing tasks. The injured limbs showed lower internal knee extension moments and increased hamstring activations. These compensations are typically seen as protective as they unload the knee joint and ...
This study reports on a large investigation to explore the advantages of customisation in total ankle replacement (TAR). Potentially, this can minimise the critical prosthesis-to-bone mismatch, improve the accuracy of the implantation and also facilitate osseointegration. A general customisation pro...
Dynamic stability of trunk movements can provide important information about spine control during movement tasks. The Pilates method focus to maintain trunk stability during exercises. The objective of this study was to compare trunk stability between two practitioner’s levels and two intensities ...

The purpose of this study was to determine the decline of gait ability by aging effects for Korean healthy adults in age group of 20s to 80s of 1,507 healthy adults. We conducted the uninterrupted walking of 1 min. duration on treadmill at their self-preferred walking speed using the shoe-type inert...
Reinforcement learning (RL) can be used to optimise motion with respect to important biomechanical variables by searching over the space of kinematics and muscle excitations in predictive simulation. We used kinematic data obtained from patients with medial compartment osteoarthritis (OA) of the kne...
Surface electromyography (sEMG) and inertial measurement units (IMU) are not established in the home environment as remote measurement systems due to difficulties associated with an intuitive and user-friendly applicability. Hence, a new sEMG-IMU sensor system was developed which consists of two arm...
The purpose of this study was to determine whether a countermovement jump could reliably be used as a substitute or dynamometer strength testing. Eighty-six high school basketball athletes were tested, and results indicate that as countermovement jump peak force, power, and impulse increase, peak co...
"If we find lots of planets like ourswe'll know it's likely that we aren't alone, and that someday we might be able to join other intelligent life in the universe."- William Borucki, principal investigator for NASA's Kepler missionPlanets in the hundreds of billions are likely caught up in the vast ...
Inertial measurement units (IMU) are used to estimate trunk kinematics. This study demonstrates that a commercially available Kalman filter is a valid method for estimating trunk flexion kinematics during the rapid and abrupt accelerations and decelerations that occur during fall prevention training...
Four specimen-specific finite element (FE) models of the knee were developed and validated to investigate ACL injury mechanisms in realistic knee models, providing valuable insight into the inter-subject differences that cannot be captured with generic models calibrated to average data.
We propose a data-driven technique to discuss the task-relevant and task-irrelevant movement variabilities while estimating the relevance of the motion sequence to task performance. Our method can unify the advantages and overcome the disadvantages of previous methods. Further, we reveal a novel fea...
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
Decreased physical activity throughout ontogeny results in decreases of peak vertical jumping performance but does not alter sub-max VO2 in a bipedal animal model.
Suture anchors are designed for use with arthroscopic techniques. In this study, finite element analysis was used to compare the stress distribution in 24 different designs of suture anchors. The results of von-Mises stress show that the optimal design reduces 14.7% von-Mises stress of a former desi...
In the preparatory measurements before launching the project in direct connection with the prepared European legislation in the field of tram safety from the point of view of pedestrians, an interesting fact was found. In Prague, it is still possible to meet trams with a front part designed in the 5...
This project determined that, in a sample of NCAA Division 1 men’s basketball players, good vertical jumpers achieve a greater reactive strength index modified (RSIMOD; jump height divided by jump time) via a faster eccentric phase and greater rate of eccentric force development. Among collegiate ...
