Effects of Viscosupplementation on Quality of Knee Joint Arthrokinematic Motion Analyzed by Vibroarthrography.

Objective: To evaluate the influence of viscosupplementation on osteoarthritic knee arthrokinematics analyzed by VAG. It is considered that intra-articular hyaluronic acid injection may improve the function of synovial joints by recovery of friction-reducing properties of articular environment.

Design: Thirty-five patients with knee osteoarthritis (grade II according to the Kellgren-Lawrence system) and 50 asymptomatic subjects were enrolled in the study.

Kinematic Chains in Ski Jumping In-run Posture.

The concept of kinematic chains has been systematically applied to biological systems since the 1950s. The course of a ski jump can be characterized as a change between closed and open kinematic chains. The purpose of this study was to determine a relationship between adjacent segments within the ski jumper's body's kinematic chain during the in-run phase of the ski jump.

Evaluation of postural asymmetry and gross joint mobility in elite female volleyball athletes.

The purpose of the study was to evaluate marked postural asymmetry and gross joint mobility in elite female volleyball athletes. Sixty-two Czech and Slovak elite female volleyball athletes (age 20.7±2.

Changes in clusterin serum concentration levels in oncologic patients during the course of spa therapy--a pilot study.

Background: Clusterin (70-80 kDa; synonym ApoJ) is a stress-associated cytoprotective glycoprotein involved in many physiological and pathophysiological processes and it is up-regulated by various apoptotic triggers in many cancers and neurodegenerative diseases.

Aim: Measurement of serum clusterin values in individuals with a history of cancer before and after spa therapy.

Methods: Serum clusterin concentration (ELISA) was determined in a group of 26 oncologic patients (4 men and 22 women) at the beginning and at the end (the 18th or 19th day) of spa treatment.
