Force enhancement is a well accepted property of skeletal muscle and has been observed at all structural levels ranging from single myofibrils to voluntarily activated m. quadriceps femoris in vivo. However, force enhancement has not been studied for multi-joint movements like human leg extension; therefore knowledge about its relevance in daily living(More)
INTRODUCTION Encephalitis is a rare complication of primary varicella-zoster virus (VZV) infection in immunocompetent children. METHODS The clinical and laboratory findings of two girls with VZV-related encephalitis are reported. RESULTS Both children presented with focal epileptic seizures, corresponding to cortical/subcortical as well as white matter(More)
Interstitial lung disease, although of prognostic impact for patients with cystic fibrosis (CF), remains difficult to assess without histopathologic investigations. As changes of peripheral blood lymphocyte subsets (LS) may accompany severe systemic lymphocyte immune responses, we compared peripheral LS of 44 patients with CF, 23 non-CF patients with(More)
BACKGROUND Muscle strength greatly influences gait kinematics. The question was whether this association is similar in different diseases. METHODS Data from instrumented gait analysis of 716 patients were retrospectively assessed. The effect of muscle strength on gait deviations, namely the gait profile score (GPS) was evaluated by means of generalised(More)
This study provides an overview on the association between premature plantarflexor muscle activity (PPF), muscle strength, and equinus gait in patients with various pathologies. The purpose was to evaluate whether muscular weakness and biomechanical alterations are aetiological factors for PPF during walking, independent of the underlying pathology. In a(More)
Pathologies that lead to biomechanical restrictions in human gait interfere with the tightly regulated muscle activation patterns that control the external moments. In order to maintain proper function, secondary mechanisms are required. The aims of this systematic review were (1) to identify secondary mechanisms in pathologic gait that have been described(More)
BACKGROUND It has previously been discussed that treatment of the hemiplegic arm in patients with cerebral palsy can improve gait parameters in the lower body. Our question was whether improving the ankle rocker with an orthosis has an effect on the upper body during walking. The main aim was to investigate, which trunk and arm kinematics of toe walking(More)
Objective: The occurrence of autoimmune diseases or deterioration of pre-existing disorders has recently been described after cytokine treatment. The present report gives evidence for acquired myasthenia gravis induced by externally administered interferon-α and interleukin-2 in a patient with metastasized renal cell carcinoma. Electromyographic(More)
Complex experimental investigations created the basis for cryosurgical treatment of colon and rectum cancer. 27 patients were chosen for cryotherapy according to strict indication. Especially developed instruments and technique are presented. A three year-follow up-study shows 19 patients alive, most of them without recurrence or troubles. Immediately after(More)
