The aim of the present study was to demonstrate the first time the non-invasive restoration of hand grasp function in a tetraplegic patient by electroencephalogram (EEG)-recording and functional electrical stimulation (FES) using surface electrodes. The patient was able to generate bursts of beta oscillations in the EEG by imagination of foot movement.(More)
Conventional prosthetic feet cannot adapt to specific conditions such as walking on stairs or ramps. Amputees are therefore forced to compensate their prosthetic deficits by modifying the kinematics and kinetics of their lower limbs. The Proprio-Foot (Ossur) intends to reduce these compensation mechanisms by automatically increasing dorsiflexion during(More)
OBJECTIVES To examine the effects of repeated detrusor injections of botulinum-A toxin (BTX) for possible changes in bladder function, muscular structure of the detrusor, increase in BTX tolerance (tachyphylaxis) and side-effects, as BTX is a new treatment alternative for patients with a neurogenic bladder condition that is difficult to treat and refractory(More)
Das mechanische Wirkprinzip des Harrington-Instrumentariums oder der Plattenstabilisierung entspricht den anatomischen oder mechanischen Gegebenheiten der traumatisch instabilen Brust- und Lendenwirbelsäule nur ungenügend. Den hier zu stellenden Anforderungen an Art der Verankerung, Kürze der Fusionsstrecke, Repositionsmöglichkeit und Variabilität können(More)
The bone mineral density (BMD), the cross- links (PYD, DPD and NTx) and the bone specific alcaline phosphatase (BAP) was investigated in a cross-sectional study in 62 male patients with spinal cord injury (SCI), n = 28 short-term (0–1 year after SCI) and n = 34 long-term SCI patients (> 5 years after SCI). Knowledge about this parameters are necessary to(More)
STUDY DESIGN Retrospective clinical study. OBJECTIVE The aim of this study was to examine whether the Tokuhashi score correlates with the neurologic outcome in early surgical treatment in metastatic spinal cord compression (MSCC). A retrospective analysis of 35 consecutive incomplete tetraplegic and paraplegic patients with vertebral metastases (VM) and(More)
In a cross-sectional study, 46 male patients with paralysis after spinal cord injury (average age 32 years; injuries sustained from 1 to 26 years ago; 33 Frankel A, 13 Frankel B, C, D) were examined clinically and by dual-energy X-ray absorptiometry (DEXA). Their bone mineral density (BMD) values were compared with age-related controls and correlated to(More)
Pro- and anti-inflammatory cytokines might have a large impact on the secondary phase and on the neurological outcome of patients with acute spinal cord injury (SCI). We measured the serum levels of different cytokines (Interferon-γ, Tumor Necrosis Factor-α, Interleukin-1β, IL-6, IL-8, IL-10, and Vascular Endothelial Growth Factor) over a 12-week period in(More)
By restricting analysis to single averaged strides considered to be characteristic for the individual under investigation, current methods in gait analysis do not exploit the full dynamics of continuous locomotion. Therefore, a novel approach is presented that is based on long-term measurements of kinematic data during treadmill walking. The method consists(More)
PURPOSE The purpose of this study was to answer the question of whether a course of in-patient rehabilitation of 4-6 weeks results in a significant postural improvement in patients with a structural kyphosis. Since all clinical measuring parameters are liable to high margins of error and measuring the surface with the formetric system has shown high(More)
