The existing literature dealing with the phasic orienting response (OR) in schizophrenia, examining, for the most part, the skin conductance component (SCOR), reports conflicting results with divergent implications for the nature of the attentional dysfunction in these patients. The present authors have contributed to that literature and to its(More)
Skin conductance (SCOR), finger pulse volume (FPV-OR), and EEG orienting responses were examined to repeated tones of either 60- or 90-dB intensity in chronic schizophrenics, nonschizophrenic psychiatric patients, and normals. SCOR reaffirmed previous findings with schizophrenics displaying significantly more frequent nonresponsiveness to 60-dB tones, and(More)
This review and critique of orienting response (OR) research in schizophrenia examines the initial Western work, outlines current positions, and notes several areas in which further lines of research are needed. Discussion involves characteristics of schizophrenic patients who are OR nonresponders; OR nonresponding as a possible trait marker; the question(More)
PURPOSE A test setup for clinical use in the awake and non-anesthetized patient measuring anteroposterior translation and rotation of the knee joint is the subject of validation. METHODS A measuring device featuring fixation of the foot at 30° of knee flexion with varus/valgus stress posts for the knee was developed. Tibial rotation (external/internal)(More)
BACKGROUND In a noticeable percentage of patients anterolateral rotational instabilities (ALRI) remain after an isolated ACL reconstruction. Those instabilities may occur due to an insufficiently directed damage of anterolateral structures that is often associated with ACL ruptures. Recent publications describe an anatomical structure, termed the(More)
AIM The aim of this study was the determination of the axial fixation load resting on smooth press-fit dowels needed for fixation of the patellar tendon graft (BTB) in order to reach the same fixation properties compared to the interference screw on anterior cruciate ligament (ACL) plasty. METHOD Bovine test specimens with 27 BTB grafts fixed in tibial(More)
Because complications of distraction osteogenesis are largely related to the long duration of therapy, increasing efforts were reached to shorten treatment by using osteoconductive replacement materials incorporating bioactive molecules such as IGF-1 and TGF-beta1. The controlled release of IGF-1 and TGF-beta1 from coated biodegradable poly(D,L-lactide)(More)
The most common failure reasons of an anterior cruciate ligament (ACL) graft are incorrect positioning of the drill channels and insufficient fixation. In many cases, one-stage revision with patellar tendon graft and the appropriate corrections are possible. For previous use of the ipsilateral patellar tendon third, an allograft seems favorable for(More)
