Abduction vs. Adduction, Flexion vs. Extension and Opposition of the Thumb

[@adeboyegrillo3408]

Great video. However, when it comes to Thumb ABduction, you have to specify *RADIAL ABDUCTION* (which you did not show at all) from *PALMAR ABDUCTION* (which you showed). The radial abduction is in the same plane as the abduction of the other four fingers and also the same plane as abducting the entire arm away from the body.

[@hareecionelson5875]

Your comment has solved 6years of confusion. Palomar abduction and radial abduction makes sense

[@irfanaabbasi9401]

I just came to learn this difference thank you so much

[@fluffyberry2222]

Radial Abduction: coronal plane
Palmar Abduction: sagittal plane

[@sachinchauhan5853]

Radial abduction and extension are same or i am confused?

[@adeboyegrillo3408]

@@sachinchauhan5853 when talking about the thumb, radial abduction looks a lot like extension but the joints involved are different.
Radial abduction occurs closer to the wrist/radius. It occurs at the carpometacarpal joint.
Extension on the other hand refers to unfolding your thumb if it was tucked under the other fingers.
It occurs farther from the wrist/radius.
It occurs at the interphalangial joints and the metacarpophalangeal joint.
I hope I haven't lost you.

I'm a DPT student who still gets very confused on this sometimes. Thank you for the clear and concise video!!

[@margaritabozhilova1919]

So helpful. Beautifully explained. Better than any book I`ve read. Thank you!

[@bernettekay3044]

I think you could add that opposition is a combination movement including abduction at the MC joint and flexion of the MCP and IP joint

[@mycah1993]

Exactly what I need!!! Thank you!!!!

Thank you 💗

[@ruqqiyawahid3813]

great video.. Nicely explained

[@alanfraser2948]

You should note that opposition is generally done with a straight thumb coming across to a straight finger. Thumb pad meeting finger pad is the full form of opposition; thumb tip to finger tip is a structural/functionally weaker version of the same. Forgive me for being so bold!

[@alanfraser2948]

This is of course spoken from the point of view of a pianist and what is useful at the keyboard.

[@Mibao_medicine]

I like your thumb nail, so cute.

[@bhumikakhatri4781]

Thank you

[@Prtyh]

Depends what you read. According to AM4 moving the thumb laterally away from the hand is radial abduction and moving the thumb towards the palm is adduction. Also if you adduct the hip or shoulder, you are moving it away from the body not in front of the body. So really I am totally confused right now.

[@1rrrrrrrrrrr544f]

Lol 😆 🤣

[@camillamoen7530]

If you adduct to the point where the thumb moves away from the palmar plane in the dorsal direction, is it still adduction? (At least I’d think you are using the adductor muscle?)

[@yonatantsegaye6008]

Thank you sir

[@GIRISHM-dk5ik]

Thankyou very much ! Nice

[@pranshuraj4461]

It's easy to understand.

Wonderful

[@qwertyrchl]

Soooo helpful!

[@gang6009]

Whats the deal with thumbs? Everyones thumb is different, some bend back some go straight. But as i get older i feel like i can utilize less muscles in my hand, and that larger ones are taking over the smaller ones, like theres two ways i can move. One way thats gonna tie me up, one way thats gonna let everything move free. It must have something to do with your heart and circulation. I feel like somethings changed since i went from a teen to 22. Like im not growing, like im slowly receding

[@Faru-fari77]

Thanks sir 🥰

[@killy_montana5939]

Is it normal that both hands of my mcp joint of the thumb doesn’t bend at all? (Born this way btw)

[@FM-oc2yv]

Amazing!

[@Zainabz005]

Thanks ❤❤

[@drnourhan6923]

Thanks🌟

[@ac-uk6hs]

Great

[@Lay2n7]

These get tricky sometimes, now they’re clear thanks 🙏🏻🩷

[@parsaabbasi9737]

Does thumb adduct on frontal plate?

[@BenG-vf7et]

Is there a name for the movement of an opposition type movement, (flexing at the base of the thumb), then extending the thumb back at the metacarpalpharangeal joint, and flexing at the IP? That’s how I hold my pen.

[@yesman6559]

Yes

[@happsingh477]

great video kind sir ...
don't suppose you'd include the nerves ass. w/ the said functions (as it pertains to the thumb)

[@GAMINGANDFITNESSREALTY]

thank so much great video :)

[@monaelisa006]

Ẅonderful explanation!

[@marielcastillo7517]

isnt then extension of thumb same as abbduction?

[@shutupimstilltalking]

You missed compilation which is like opposition but to the base of the pinky

[@apnews2791]

Helpfull vedio

[@dom4638]

great vid!

[@bereketaklilu8020]

What about extension?

[@1999diehard]

lol... doctors complicate everything for medical students.... thanks for telling us what are these "movements" lol

[@domenicminnella568]

I just remember that the movements, aside from opposition are in the opposite plane of digits 2-5....

[@user-bx1cj5xw3s]

ثنى الابهام ‏‪0:49‬‏

[@mariannecapili9040]

Hi! If your thumb is in opposition, is it also in flexion?

[@jackel142]

hyperflexion maybe?

[@vineshmanohar2060]

All the above mentioned movements are with respect to the Carpometacarpal joint of the thumb! What ur saying is flexion of the Interphalyngeal joint of the thumb. Both are different movements at different joints.

[@abheeksharma987]

It's flexion and medial rotation

[@SalmanAli-zj6ht]

No

[@swarupanandamohanty2253]

Flexion at MCP Joint + Medial rotation at CMC joint

[@nefertiti7367]

The best

[@alefig2035]

I can’t oppose my thumb to my pinky wtf I had carpal tunnel surgery in 95 and lost lots of range of motion . Anybody other have the same issue ?

[@bangtan4342]

Tyyy kingggg😘❤️

[@joyalgeorge5075]

Poli🔥

[@rafathamdanable]

Abduction part still confusing. not very clear

[@aliman4234]

Thaannkkkkssss

[@lucylast986]

Are the actions coming from the MCP joint?

[@hanelebacklund1540]

Lucy Last it is cmc joint that does the abduction/adduction and opposition/retropostion. Mcp only does flexion/extension

[@prabhash2363]

I dont have MP joint and hence I am not able to flex

[@timontasicc9580]

great video, but the shown opposition is actually incorrect as the opposition is only movement of the I. metacarpal to the V. metacarpal :)

[@fawzibriedj4441]

How about when the thumb stays in the plane of the hand, but moves laterally like that : ✋

[@1rrrrrrrrrrr544f]

Extension 😊

[@janvanderhave6736]

thanks future me
