The mechanical characteristics of ankle foot orthoses (AFOs), such as the stiffness and neutral angle around the ankle and metatarsal-phalangeal (MTP) joints, are rarely quantified. Paradoxically, it is expected that these characteristics determine the function of the AFO in pathological gait. Therefore a device to determine these AFO characteristics named(More)
The paper describes a newly developed method, called IRIS, for the precise measurement of horizontal and vertical eye movements. The method is based on the principle of reflection of infra-red light by the iris/sclera boundary. IRIS combines, when the frequency bandwidth is from DC to 100 Hz, a dynamic measuring range of 30° with a low noise level of 1 min(More)
The paper describes a newly developed method, called IRIS, for the recording of dynamic pupillary reflexes simultaneously in both eyes. The method is based on the principle of reflection of infra-red light by the iris/pupil boundary. IRIS incorporates a head-fixed. Maxwellian viewing-light stimulator driven by a function generator. IRIS enables pupillary(More)
Following heart transplantation remodeling of the donor heart causes changes in the extracellular myocardial matrix. We investigated 20 right ventricular endomyocardial biopsies taken 17+/-4 days (group I, n=9) and 63+/-13 days (group II, n=11) after heart transplantation from 16 patients transplanted for end-stage cardiomyopathy (15 dilated/1 ischemic).(More)
A patient is reported, who tried to simulate a positive patch test reaction by scratching one of the patch-tests. When reading the results of patch-testing, the possibility of manipulation has to be considered, especially when dealing with compensation cases. Certain modifications of the test are proposed to avoid these problems.
