Background: F-wave study, part of electrodiagnostic study, has had a controversial sensitivity in the diagnosis of lumbosacral radiculopathy. Objectives: We aimed to compare F wave parameters obtained from the tibial nerve of both extremities in patients with unilateral S1 radiculopathy. Materials and Methods: The study was done from March to September 2015 in the Electrodiagnostic laborator...

BACKGROUND Dysfunctional spinal circuit may play a role in the pathophysiology of amyotrophic lateral sclerosis (ALS). The purpose of this study was to use F waves for assessment of segmental motoneuronal excitability following upper motor neuron (UMN) dysfunctions in ALS. METHODS We studied the F waves of 152 ulnar nerves recorded from abductor digiti minimi in 82 patients with ALS. Two grou...

To investigate the effect of physical therapy on F-wave characteristics in a patient with cerebrovascular disease, we tested the relationship between F-wave waveforms and the recovery of voluntary movement on the affected side. We measured F-waves of affected thenar muscles after stimulating the affected median nerve at the wrist in a left hemiplegia patient (female, 60 years old) with cerebrov...

We demonstrate that there is an optimal forcing length scale for low Prandtl number dynamo flows that can significantly reduce the required energy injection rate. The investigation is based on simulations of the induction equation in a periodic box of size 2πL. The flows considered are the laminar and turbulent ABC flows forced at different forcing wave numbers k_{f}, where the turbulent case i...

For a compact millimeter wave imaging system it is very important to design every component into small size, for the components in a millimeter wave system are usually much larger than those in an optical imaging system due to relatively long wave lengths. In this paper, we suggest a kind of binary diffractive lens (BDL) designed using double negative materials (DNG) as the objective lens for a...
