The interaction between the vastus medialis and vastus intermedius and its influence on the extensor apparatus of the knee joint

Grob, Karl ; Manestar, Mirjana ; Filgueira, Luis ; Kuster, Markus S. ; Gilbey, Helen ; Ackland, Timothy

In: Knee Surgery, Sports Traumatology, Arthroscopy, 2017, p. 1–12

Although the vastus medialis (VM) is closely associated with the vastus intermedius (VI), there is a lack of data regarding their functional relationship. The purpose of this study was to investigate the anatomical interaction between the VM and VI with regard to their origins, insertions, innervation and function within the extensor apparatus of the knee joint.Methods: Eighteen human...

A newly discovered muscle: The tensor of the vastus intermedius

Grob, Karl ; Ackland, T. ; Kuster, M.S. ; Manestar, M. ; Filgueira, Luis

In: Clinical Anatomy, 2016, vol. 29, no. 2, p. 256–263

The quadriceps femoris is traditionally described as a muscle group composed of the rectus femoris and the three vasti. However, clinical experience and investigations of anatomical specimens are not consistent with the textbook description. We have found a second tensor-like muscle between the vastus lateralis (VL) and the vastus intermedius (VI), hereafter named the tensor VI (TVI). The aim of...

Wirkung von transkutaner elektrischer Nervenstimulation auf die Schmerzintensität bei Patienten mit Gonarthrose : systematische Literaturübersicht

Anthenien, Deborah ; Jossen, Renata (Dir.)

Mémoire de bachelor : Haute Ecole de Santé Valais, 2014.

Die Gonarthrose gehört zu den häufigsten Gelenkerkrankungen. Die Prävalenz der Gonarthrose wird zwischen 15 – 55% angegeben. Der Schmerz ist das Hauptsymptom einer Gonarthrose. Schmerzen führen zu einer reduzierten Lebensqualität und mindern die Autonomie. Zur Therapie stehen medikamentöse und nichtmedikamentöse Behandlungsmöglichkeiten zur Verfügung. Da bei den medikamentösen...

Supervised slackline training improves postural stability

Pfusterschmied, Jürgen ; Buchecker, Michael ; Keller, Martin ; Wagner, Herbert ; Taube, Wolfgang ; Müller, Erich

In: European Journal of Sport Science, 2013, vol. 13, no. 1, p. 49-57

The present study investigated whether or not four weeks of supervised slackline training (SLT) performed on nylon webbing improves postural stability. Twenty-four healthy adults participated in the study and were assigned to either SLT (n=12) or a control (CON) group (n=12). The SLT group completed a four week training program, while the CON group received no training. Centre of gravity...

Differential effects of stimulus characteristics during knee joint perturbation on hamstring and quadriceps reflex responses

Bruhn, Sven ; Leukel, Christian ; Gollhofer, Albert

In: Human Movement Science, 2011, vol. 30, no. 6, p. 1079-1091

When stretching muscles of the ankle joint, stretch velocity and amplitude were shown to selectively influence specific parts of the stretch reflex. The present study investigated whether similar effects can be observed at the knee joint. Seventeen subjects were exposed to sudden anterior tibial translations. The influence of stimulus amplitude was analyzed by applying a low (LIMP) or high...

Exposure to a high-fat diet alters leptin sensitivity and elevates renal sympathetic nerve activity and arterial pressure in rabbits

Prior, Larissa J. ; Eikelis, Nina ; Armitage, James A. ; Davern, Pamela J. ; Burke, Sandra L. ; Montani, Jean-Pierre ; Barzel, Benjamin ; Head, Geoffrey A.

In: Hypertension, 2010, p. -

The activation of the sympathetic nervous system through the central actions of the adipokine leptin has been suggested as a major mechanism by which obesity contributes to the development of hypertension. However, direct evidence for elevated sympathetic activity in obesity has been limited to muscle. The present study examined the renal sympathetic nerve activity and cardiovascular effects of a...

Antimicrobial coatings for implant surfaces

Brunetto, Priscilla S. ; Fromm, Katharina M.

In: Chimia, 2008, vol. 62, no. 4, p. 249-252

Body-foreign materials are used more and more frequently in our lives: joint implants (hips, knees, fingers, etc.), catheters, pacemakers, dental and aesthetic implants, etc. The increasing numbers of patients requiring such implants also raises the absolute numbers of implant-related infections. Thus, it is known that body-foreign materials are prone to bacterial adhesion and subsequent biofilm...
