Background: Surgery for bone tumors around the knee often involves extensive resection, making subsequent prosthetic reconstruction challenging. While carbon fiber-reinforced polyetheretherketone (CF-PEEK) has been widely used in orthopedic implants, its application tumor-type prosthesis is limited. This study aims to evaluate feasibility of using 30wt% and 60wt% (CF30-PEEK CF60-PEEK) as materi...

In 13 unloaded living knees we confirmed the findings previously obtained in the unloaded cadaver knee during flexion and external rotation/internal rotation using MRI. In seven loaded living knees with the subjects squatting, the relative tibiofemoral movements were similar to those in the unloaded knee except that the medial femoral condyle tended to move about 4 mm forwards with flexion. Fou...

Milan is an increasingly safe city. Despite this, the insecurity perceived by citizens growing. Particularly in social housing districts, squatting considered institutions, public opinion, but also most regular residents, as one of principle causes urban insecurity. Based on ethnographic research conducted between 2015 and 2017, this article proposes anthropological analysis policies, norms, pr...

BACKGROUND Squatting produces a prompt increase in cardiac output and arterial blood pressure which is accompanied by an immediate decrease in heart rate and forearm vascular resistance. The rise in cardiac output and blood pressure has been attributed to augmented venous return from compression of leg veins, while the decreases in heart rate and forearm vascular resistance are probably due to ...

The purpose of this study was to investigate the variables that contributed most to maximum throwing distance in the hammer throw event in track and field. A 41item survey instrument was developed to collect data regarding national level collegiate hammer throwers throughout the United States. Multiple regression analysis for hammer throw personal record (PR) yielded a significant model (r=0.81...

Purpose. Complex training (CT) involves the coupling of two exercises ostensibly to enhance the effect of the second exercise. Typically, the first exercise is a strength exercise and the second exercise is a power exercise involving similar muscles. In most cases, CT is designed to enhance power. The purpose of this study was twofold. First, this study was designed to determine if lower body p...

Here we demonstrate our Intelligent Coaching Space, an immersive virtual environment in which users learn a motor action (e.g. a squat) under the supervision of a virtual coach. We detail how we assess the ability of the coachee in executing the motor action, how the intelligent coaching space and its features are realized and how the virtual coach leads the coachee through a coaching session.
