According to the established clinical tradition about the distribution of weakness, the ratios of flexor/extensor strength of patients with upper motor neuron lesions are expected to be relatively high for the elbow and wrist and low for the knee. To assess the diagnostic value of these patterns of weakness, muscle strength of 70 patients with limb weakness of central or peripheral origin was m...

In this paper I discuss some of the strengths and weaknesses of two different approaches to teaching motor skills to students in outdoor education and outdoor recreation settings. Using acronyms to describe their stages: DEDICT is a six step, direct instructional model that some outdoor leaders may already be familiar with; and FERAL is my adaptation of a discovery learning approach that can be...

Guillain-Barré syndrome (GBS) is an acute peripheral neuropathy that develops as a result of post-infectious immune-mediated nerve injury. It can be classified into classic and variant GBS. Acute motor axonal neuropathy (AMAN) is a subtype of GBS with the key clinical features of pure motor weakness, areflexia, absence of sensory symptoms, and lack of neurophysiologic evidence of demyelination....

OBJECTIVE Muscle weakness develops rapidly after stroke, adversely affecting motor performance, and contributing to reduced functional ability. While the contributions of structural and functional alterations in skeletal muscle to post-stroke weakness have been well described, the relationship between motor pathway integrity, measured using both radiological and electrophysiological techniques,...

An 86 year-old woman suffered a left internal capsule stroke one month before these photos. She had right facial weakness along with mild right arm and leg weakness as residua. Six years earlier she had had a left sided Bell’s palsy with an excellent recovery. Photo A shows a mildly increased right palpebral fissure and mildly reduced right naso-labial fold. These findings indicate mild facial ...

primary sjorgen syndrome is one of the commonest autoimmune diseases with characteristic of involvement of lachrymal and salivary glands, but other organ involvements as peripheral and central nervous system are also possible. the reported case is a 23 year old lady presented with progressive sensory ataxia and weakness of four limbs, bilateral sensory hearing loss and cognitive impairment with...

We describe a patient who developed progressive weakness in all limbs without sensory symptoms 4 weeks after upper respiratory system infection. Electrophysiological findings suggested a new variant of Guillain-Barré syndrome named "acute motor conduction block neuropathy". Electrophysiological studies were performed at admission, 12th and 28th weeks. At the 28th week, the clinical examination ...
