Hello!
This is practical exam related concept.
In a patient with neurological symptoms, you'd like to know whether the person is left handed or right handed. Why?
Dominant hand is important in medicine because it helps us figure out the dominant hemisphere - especially, in patients with stroke.
People who are right handed have their left cerebral hemisphere dominant. 70% left handed people are left hemisphere dominant.
To figure out handedness, you can ask the person with which hand he writes. If illiterate - You can ask with which hand he prefers to eat, combs hair, etc.
Threading a needle is an excellent way to determine handedness because very frequently people tend to hold the thread in the dominant hand and hold the needle with the non dominant hand.
That's all!
I'm left cerebral hemisphere dominant. You?
