Guillain\u2013Barr\u00e9 syndrome Guillain\u2010Barre syndrome (GBS), polymyositis\/dermatomyositis (PM\/DM), generalized myasthenia gravis (MG), and hypokalemic periodic paralysis (HPP) constitute the majority of cases of flaccid quadriparesis. Few patients from any of these disease groups lack the cardinal clinical features. We established clinical marker(s) that might have significant discriminating power for diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>Forty\u2010six patients satisfied all of our criteria.

Jaw\u2010opening weakness was found in 71.4% of PM\/DM, 83.3% of HPP, and 4.1% of GBS cases.
