BACKGROUND & OBJECTIVES Each skeletal muscle is usually supplied by two or more nerve roots and if one nerve root is affected and the other is spared, the clinically used F wave minimum latency can still be normal. An F wave index was constructed taking into consideration the other parameters of the F wave such as persistence, chronodispersion, latency, arm-length to determine its usefulness in...

OBJECTIVES Investigation of pathophysiology of F wave disappearance in demyelinating neuropathies. METHODS The peripheral motor nerve conduction was studied by motor evoked potential (MEP) on transcranial magnetic stimulation as well as conventional nerve conduction studies before and after the treatment in 26 patients with inflammatory demyelinating neuropathies. In addition, serum antigangl...

OBJECTIVE To assess the effect of motor imagery, as a rehabilitation method in stroke, on F-wave parameters that undergo changes during upper motor neuron involvement. METHODS Twenty-one fully conscious hemiparetic stroke survivors with a completely plegic hand (power 0/5) and a minimum interval of 72 hours since stroke were recruited into this study. The mean F-wave latency, amplitude, and p...

OBJECTIVES The purpose of this study was to test the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) over the non-lesional hemisphere on motor neuron excitability of the paretic upper limb in post-stroke patients by electrophysiological examination. MATERIALS AND METHODS Thirteen post-stroke patients with spastic upper limb hemiparesis were studied (age, 57.5 ± 11...

scattering of an incoming wave train by a discontinuity at the upper surface of the ocean over a uniform porous bottom of finite depth is considered here in the framework of linearized water wave theory. by employing residue calculus method, the reflection and transmission coefficient are obtained. these coefficients are computed numerically for different values of the porosity parameter g and ...

A frequency $ n -cube F {}^{n}(4;2,2) is an -dimensional 4 -by-…-by- array filled by 0 s and 1 such that each line contains exactly two s. We classify the -cubes {}^{4}(4;2,2) , find a testing set of size 25 for {}^{3}(4;2,2) derive upper bound on number . Additionally, every greater than 2 we construct cannot be refined to Latin hypercube, while its sub-F {}^{n-1}(4;2,2) can.
