Joint disease causes weakness and wasting of adjacent muscles, in part because of inability to fully activate these muscles voluntarily. Previous findings suggest that transcranial magnetic stimulation (TMS) paired with muscle contractions enhances maximal voluntary contraction force (MVC) in healthy subjects by improving voluntary activation (VA). The aim of the present study was to evaluate whet...<br/><br/>Dietmar Urbach, Alexander Berth, Friedemann Awiszus (2005) <i>Muscle Nerve</i> <i></i> <i></i> 32: 2 164-169<br/>

It is well accepted that transcranial magnetic stimulation (TMS) can modulate motor cortex excitability long after application. Furthermore, a positive TMS effect on the ability to perform a maximal voluntary contraction (MVC) of the quadriceps femoris muscle has been described. However, stimulus strength dependence and duration of this effect are currently unknown. In the present study these para...<br/><br/>Dietmar Urbach, Friedemann Awiszus (2002) <i>Exp Brain Res</i> <i></i> <i></i> 142: 1 25-31<br/>

AIM: The reduction in quadriceps femoris muscle activation is considered to be one of the major mechanisms involved in pathological motion patterns in patients with osteoarthritis (OA) of the knee. These activation deficits are, at least in part, reversible after total knee arthroplasty (TKA). The purpose of this study was to investigate the effects of TKA on motion patterns in patients with OA of...<br/><br/>A Berth, D Urbach, R Becker, F Awiszus (2002) <i>Zentralbl Chir</i> <i></i> <i></i> 127: 10 868-872<br/>

The loss of full muscle activation contributes to weakness of the quadriceps muscle in patients with deficiency of the anterior cruciate ligament (ACL). We examined whether a deficit of voluntary activation (VA) of the quadriceps muscle can be reversed by reconstruction of the ACL and assessed its influence on muscle strength and clinical parameters. We evaluated 12 male subjects with an isolated ...<br/><br/>D Urbach, W Nebelung, R Becker, F Awiszus (2001) <i>J Bone Joint Surg Br</i> <i></i> <i></i> 83: 8 1104-1110<br/>

We describe a new arthroscopic technique to reinforce the torn inferior glenohumeral ligament (IGHL) and the elongated capsule to the glenoid rim. The arthroscope is inserted over the superior portal and, after the insertion of a suture anchor, both limbs are pulled out over the posterior portal. The IGHL is grasped and pulled upward onto the glenoid rim using a suture retriever clamp inserted ove...<br/><br/>W Nebelung, M Röpke, D Urbach, R Becker (2001) <i>Arthroscopy</i> <i></i> <i></i> 17: 4 426-429<br/>

Osteotomy close to the knee is an established method to treat degenerative osteoarthritis of the knee with varus or valgus deformity. However, indications, surgical techniques and results are discussed controversially. This article gives an overview of those surgical procedures most commonly used for correcting valgus and varus deformities. Supported by our results it is shown that osteotomy of th...<br/><br/>W Schultz, D Urbach (2000) <i>Zentralbl Chir</i> <i></i> <i></i> 125: 6 523-531<br/>

Between 1995 and 1997, five patients were operated on with a large osteochondral defect of the femoral condyle using the lateral third of the patella. The age of the four male and one female ranged from 18 to 23 years. Initially all of them suffered from an osteochondrosis dissecans which was located at the typical site on the medial condyle of the femur, in the maximal weight bearing region.

Short-interval, paired-pulse transcranial magnetic stimulation (TMS) is usually used to demonstrate intracortical inhibition. It was shown recently that with short-interval, paired-pulse TMS a facilitation - called intracortical I-wave facilitation - can also be demonstrated. It was the aim of this study to investigate which stimulus conditions lead to intracortical inhibition and what conditions ...<br/><br/>F Awiszus, H Feistner, D Urbach, H Bostock (1999) <i>Exp Brain Res</i> <i></i> <i></i> 129: 2 317-324<br/>
