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...

Running gait kinetics and kinematics can be measured in the lab using force-instrumented treadmills and 3D motion capture. However, these tools are not feasible for use in the daily training environment of recreational and elite runners. A prototype wearable smart garment (SG) has been developed to ...

The purpose of this work was to evaluate changes in forearm muscle co-contraction caused by sudden wrist perturbations during a dynamic wrist tracking task using a haptic wrist robot. Surface electromyography was recorded from eight muscles of the upper-limb. Co-contraction ratios for all muscle pai...

There are conflicting observations regarding residual force enhancement (RFE) in cardiac muscle. In this study, we intended to re-examine RFE in cardiac myofibrils. RFE was tested after active stretches from average sarcomere lengths of i) 1.8 to 2.0 µm (n = 8), and ii) 2.0 to 2.2 µm (n = 8). All ...

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...

The in-vivo dynamic characteristic of normal knee joint is valuable for the cure of knee osteoarthritis and knee prosthesis design. In this study, a unique in-vivo experimental evaluated subject-specific finite element musculoskeletal (FE-MS) model with high accuracy intact knee was created and used...

Major knee ligament injuries, such as ACL injury, cause long-term neuromuscular dysfunctions and morphological changes. Individuals after ACL reconstruction surgery (ACLR) exhibit quadriceps weakness and decreased force steadiness even months after surgery. The current investigation aimed to examine...

Basal myosin oscillation is barely dependent on actomyosin cortical tension, indicating that oscillation is mainly from biochemical reaction. During basal myosin oscillation, Rho1 proteins and Rho1 activity are mainly distributed and enriched at and near basal junction and the major control of basal...

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 ...

Studies examining forefoot strike (FFS) has lower eccentric quadriceps work during the braking phase of the running compared with rearfoot strike (RFS). Lower eccentric quadriceps work may result in lower knee loading. The purpose of this study was to examine whether the patellofemoral joint contact...

A probabilistic evaluation of scapulohumeral muscle functional roles revealed a high degree of sensitivity in moment arms and lines of action to alterations in musculoskeletal geometry in healthy adults. Comparisons of model-predictions against published data highlight the need to validate lines of ...

We compared the effects of shoe midsole cushioning on the knee compression impulse during the first 50 ms of ground contact between midfoot (MF) and rearfoot (RF) runners, while controlling for the effects of: knee joint angle at contact, knee joint stiffness, shank velocity at contact, pelvis horiz...
