Functional electrical stimulation (FES) may be able to augment functional arm and hand movement after stroke. Poststroke neuroprostheses that incorporate voluntary effort and FES to produce the desired movement must consider how forces generated by voluntary effort and FES combine, even in the same muscle, in order to provide an appropriate level of stimulation to elicit the desired assistive f...

This presentation will review briefly the current practice and state of the art in functional electrical stimulation (FES) as applied to stroke, head injured or brain tumour operated patients. A similar application is used in paretic patients following trauma or other aetiology. Over 20 years experience in the application of FES, as practised in Ljubljana, will be highlighted and the devices cu...

OBJECTIVE this study aimed to perform a comprehensive validation of the 16-item and 7-item Falls Efficacy Scale International (FES-I) by investigating the overall structure and measurement properties, convergent and predictive validity and responsiveness to change. METHOD five hundred community-dwelling older people (70-90 years) were assessed on the FES-I in conjunction with demographic, phy...

Abstract The effects of long-term Functional Electrical Stimulation (FES) assisted walking on ankle dynamic stiffness were examined in spinal cord injured (SCI) subjects with incomplete motor function loss. A parallelcascade system identification method was used to identify intrinsic and reflex contributions to dynamic ankle stiffness at different positions with subjects instructed to remain re...

In this study, fuzzy expert system (FES) was designed by using Matlab software for determination of performance and emission characteristics of a gasoline engine which is Briggs and Stratton Vanguard trademark, a cylinder, cylinder volume 182 cm. In the designed FES, intake valve opening advance (advance-) and engine speed (nd/d) were determined as input parameters whereas torque (Me-Nm), power...

16 α -[(18)F]-fluoroestradiol ([(18)F]FES), a steroid-based positron emission tomography (PET) tracer, has emerged as a dependable tracer for the evaluation and management of estrogen receptor-positive (ER+) breast cancer patients. We have developed a fully automatic, one-pot procedure for the synthesis of [(18)F]FES using the Eckert & Ziegler (E & Z) radiomodular system. After [(18)F]fluorinat...

This study was conducted to investigate the change in the kinematics and physiological cost of walking that occurs during training with functional electrical stimulation (FES)-assisted walking in persons with incomplete injuries. The main effect of FES-assisted walking was to change hip excursion and ankle dorsiflexion during swing and at foot contact, whereas training with FES-assisted walking...

OBJECTIVE Demonstrate brain perfusion changes due to neuronal activation after functional electrical stimulation (FES). METHOD It was studied 14 patients with hemiplegia who were submitted to a program with FES during fourteen weeks. Brain perfusion SPECT was performed before and after FES therapy. These patients were further separated into 2 groups according to the hemiplegia cause: cranial ...

The aim of this study was to determine whether the downregulation of endogenous Fes by siRNA in cultured endothelial cells affects vascular endothelial growth factor-A (VEGF-A)-induced chemotaxis and capillary-like morphogenesis, which are considered as angiogenic cellular responses in vitro. VEGF-A-treatment induced autophosphorylation of Fes in cultured endothelial cells. LY294002, a phosphoi...

The human bcr gene encodes a protein with serine/threonine kinase activity, CDC24/dbl homology, a GAP domain, and an SH2-binding region. However, the precise physiological functions of BCR are unknown. Coexpression of BCR with the cytoplasmic protein-tyrosine kinase encoded by the c-fes proto-oncogene in Sf-9 cells resulted in stable BCR-FES protein complex formation and tyrosine phosphorylatio...
