Class I reflects ocular muscle weakness with normal strength elsewhere, while Class II covers mild weakness of non-ocular muscles, with possible ocular weakness. Subclasses IIa/IIb and IIIa/IIIb distinguish predominant limb/axial versus oropharyngeal/respiratory involvement. Class IV denotes severe non-ocular weakness with subclass IVa/IVb, and Class V identifies cases requiring intubation (with or without mechanical ventilation), with feeding-tube-only patients categorized as IVb.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/mgfa-clinical-classification-class-i-v/565485/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/mgfa-clinical-classification-class-i-v/565485.png","ImageObject",442,249,{"name":42,"@type":43},"jay","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-21","2026-10-13",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",5,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What defines Class I in the MGFA clinical classification?","Question",{"text":63,"@type":64},"Class I is any ocular muscle weakness, possibly affecting eye closure, while all other muscle strength remains normal.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How are Class IIa and IIb distinguished?",{"text":68,"@type":64},"Class II is mild weakness in muscles other than ocular muscles, with possible ocular involvement.
