The classical stretch shortening cycle (SSC) describes sagittal joint flexion–extensions in motions like running or hopping. However, lateral movements are integral components of team sports and are associated with frontal plane joint displacements. The purpose of this study is to identify neuromuscular and kinematical mechanisms determining motor control(More)
BACKGROUND Gender and fatigue are thought to affect the anterior cruciate ligament injury risk. In spite of much effort, the influence of these factors on knee joint biomechanics is still under discussion. The purpose of this study was to investigate kinematics, kinetics, and active muscle control strategies of the knee joint across gender in fatigue(More)
Load-dependant adjustments in lateral jumps are thought to rely on foot placement and on upper leg’s kinematic and neuromuscular adaptations. The aim of this study was to elucidate task-specific adjustments during the initial impact phase under varying stretch-loads by the comparison of lateral jumps and lateral landings. Ten subjects performed lateral(More)
AIM Sledge jump systems (SJS) are often employed to examine the underlying mechanical and neuromuscular mechanisms of the stretch-shortening cycle (SSC) as they allow the systematic variation of impact velocity and energy. However, in existing SJS the jumps are not very comparable to natural jumps because of the long contact times (∼200%), which prevent the(More)
Noncontact injuries frequently occur during soccer matches and training. The purpose of this study was to examine the influences of different soccer shoe studs to kinematic, kinetic and electromyographic parameters in the knee joint. Six male soccer players performed complex turning movements (180 degrees ) with bladed and round studded soccer shoes. Ground(More)
INTRODUCTION Osteoarthritis of the knee affects millions of people. Elastic knee sleeves aim at relieving symptoms. While symptomatic improvements have been demonstrated as a consequence of elastic knee sleeves, evidence for biomechanical alterations only exists for the sagittal plane. We therefore asked what effect an elastic knee sleeve would have on(More)
BACKGROUND Chronic ankle instability (CAI) is a term that is not well defined until now in spite of a large body of respective literature. Most frequently this umbrella term is used synonymously for functional ankle instability and the role of the mechanical component is not fully understood. PATIENTS/MATERIAL AND METHODS In a cohort consisting of 15(More)
Die für den chronisch Leberkranken zumeist schicksalsbestimmende portale Hypertension (PH) überschreitet bereits bei chronischer Hepatitis weit die oberen Grenzwerte. Mit Hilfe der laparoskopischen transhepatischen Manometrie (LTM) in den Ästen der V. portae und V. hepatica ermittelten wir bei chronisch-persistierender Hepatitis (CPH) Pfortaderdrucke von(More)
Laparoscopic transhepatic measurement of pressures in the branches of the portal vein (and hepatic vein) were performed in 42 patients with hepatitic cirrhosis of the liver and compared with those obtained in patients with other defined causes of cirrhosis (alcohol, pigment, Budd-Chiari syndrome, right heart failure). Mean portal vein pressure was 27.2,(More)
BACKGROUND Despite massive research efforts, it remains unclear how mechanical ankle instability (MAI) and functional ankle instability (FAI) affect joint control in the situation of ankle sprain. Thus, the purpose of this study was to evaluate whether individuals with MAI have deficits in stabilising their ankle joint in a close-to-injury situation(More)
