OBJECTIVE To clarify the features of decremental responses following repetitive nerve stimulation in patients with motor neuron diseases (MNDs), in comparison with myasthenia gravis (MG). METHODS The subjects consisted of 48 MND, 39 generalized MG and 19 ocular MG patients. Six muscles, both proximal and distal muscles, were tested. RESULTS Significant(More)
OBJECTIVE We aimed to analyze the clinical and histopathologic features of cancer-associated myositis (CAM) in relation to anti-transcriptional intermediary factor 1 γ antibody (anti-TIF1-γ-Ab), a marker of cancer association. METHODS We retrospectively studied 349 patients with idiopathic inflammatory myopathies (IIMs), including 284 patients with(More)
PURPOSE Diabetic patients without symptoms of carpal tunnel syndrome (CTS) may frequently show a prolongation of their median distal latency. Previous authors have reported that diabetic polyneuropathy (DPN) and CTS were differentiated by evaluating the sensory conduction velocity (SCV) distal to the palm. This study aimed to clarify this issue. METHODS(More)
INTRODUCTION It is generally believed that a shorter stimulus duration is less painful in nerve conduction studies (NCS). We investigated whether a shorter duration stimulus is actually less painful when the same physiological effect, such as supramaximal stimulation, is achieved in motor NCS. METHODS The tibial nerve was stimulated at the ankle in 14(More)
We report 13 patients presenting with predominantly sensory strokes due to brainstem infarction, without any other brainstem symptoms such as hemiparesis, dysarthria or vertigo. All of them had lacunar infarctions localized at the medial lemniscus and/or spinothalamic tract, at the pontine (12 patients) or midbrain (1 patient) tegmentum. The presenting(More)
