Bienfang's test is a clinical test used in the diagnosis of ocular myasthenia gravis. It is used in conjunction with other examination techniques such as Cogan's lid twitch test [ 1 ] or enhancement of blepharoptosis from prolonged upward gaze.
Myasthenia gravis affects 50 to 200 people per million. [3] [4] It is newly diagnosed in 3 to 30 people per million each year. [13] Diagnosis has become more common due to increased awareness. [13] Myasthenia gravis most commonly occurs in women under the age of 40 and in men over the age of 60. [1] [5] [14] It is uncommon in children. [1]
Myasthenia gravis, or MG, is a chronic autoimmune neuromuscular disorder that causes muscle weakness and fatigue. ... Blood tests are also often used to identify associated antibodies. "About 80% ...
A tensilon test, also called an edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis. [1] It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis.

Acquired myasthenia gravis is the most common neuromuscular junction disease.(reference 7) Important observations were made by Patrick and Lindstrom in 1973 when they found that antibodies attacking the acetylcholine receptors were present in around 85% of cases of myasthenia gravis.(reference renamed form 13)(reference 36) The remaining ...
In some conditions, such as myasthenia gravis, muscle strength is normal when resting, but true weakness occurs after the muscle has been subjected to exercise. This is also true for some cases of chronic fatigue syndrome, where objective post-exertion muscle weakness with delayed recovery time has been measured and is a feature of some of the ...
