Biomechanics Lecture 7: Wrist & Hand

[@kevram8844]

By far the best a&p video I've ever watched: good information, good description, easy & fun

[@RehabScience]

Wow, thank you! Glad you enjoyed it!

[@thefakeaussie]

Wish Id found this series sooner they've all been super helpful for developing a baseline before diving into the textbooks for my clinical kinesiology exams!

[@RehabScience]

I am glad to hear they have been helpful to you!

[@gabriellenoel3233]

Amazing videos!! Makes everything easy and simple to understand. I binged all your videos for my biomechanics class. Thanks!

[@RehabScience]

Haha! I’m glad they were helpful to you!

I injured once that area called TFCC from practicing handstand. The result was 7 months of pain with dorsi flexion and exercises like push ups with palm on the ground. So I switched to train on p-bars and doing push ups in knuckles , thankfully there was no pain. Amazing video as always with many informations, thank you !

[@RehabScience]

So glad to hear you were able to find ways to train around the pain and are enjoying the videos!

[@scuddelpilar8450]

I'M LEARNING SO MUCH TO YOUR VIDEO AS A PT STUDENT. THANKYOU!!!

[@RehabScience]

That's awesome!

[@CollinesKiptoo]

its really one of the best lucture with content and more explanation

[@Ludix147]

Thanks, really well explained and easy to follow! I have recently damaged both my TFCCs and wanted to better understand how the wrist fits together, so this lecture was just right for me!

[@RehabScience]

So glad to hear it was helpful!

[@skwarrawks8711]

I love these, please make them longer if possible

[@RehabScience]

Glad you are enjoying them!

[@elifmelif1865]

Watching all your bio videos one by one theyre the bst😊

[@LevysFitness]

Great video, Thank you!

[@RehabScience]

Thanks, friends! Glad you liked it!

[@sagharamininejad2884]

Thanks a lot Doctor. It was amazing and well explained. I really enjoyed it and really useful for me…(second year physiotherapy student)

[@RehabScience]

Glad to hear that!

[@asociaciongdsmexico5116]

Thanks for the video ! From where is the dissection video of the wrist in this lecture ?

[@yasamanbahadori1953]

Perfect 👍🏻😍

[@asociaciongdsmexico5116]

Where can I see more videos of dissected structures as the one you show in this lecture?

[@rosemathew4545]

thank you for the very informative lecture.

[@RehabScience]

You’re welcome!

[@kungfubear4364]

Great series. I'm working my way through.

[@RehabScience]

Thank you! So glad you are enjoying the lectures!

nice video, u mentioned only 2 kind of movement of the wrist (extension + flexion and ulnar + radial deviation) but how does the twist work? just vulgarly calling it twist of the hand; i really appreciated those sweet number about angle measurement of the various degree of freedom of the wrist movement, so i was wondering how much does the hand twist. sorry if it's a bit confusing i don't know how to explain myself proeprly

[@savvasskordis9687]

The hand twist/rotates along with the forearm. This action is called supination, the thumb looks up to the ceiling and then the forearm rotates and your thumb looks to your right with palm facing up to ceiling and pronation is when the thumb looks up to the ceiling and then the forearm rotates and your thumb looks to your left with palm facing down to the ground. Pronation and supination occurs at the distal and proximal radioulnar joints with the radius being the bone that moves in relation to the ulnar. About 75 degrees of pronation and 85 degrees of supination. :))

[@RehabScience]

Twisting (pronation and supination) come from the joints in the forearm. If you watch the video all the way through, I explained this in more detail.

[@zetsubonokami9167]

thank you for the info, maybe i lost a bit of focus on that part, if it was on the arm video i still have to see it

[@zetsubonokami9167]

@@savvasskordis9687 thank you for the explanation and for the sweet numbers too

[@ViralChubb]

Great video! When can we expect the lower extremity lectures?

[@RehabScience]

I just put the first one up today!

Any program for finger arthritis to help a guitar player? Thank you.

[@tahirmushtaq5155]

Thank you sir ❤

[@RehabScience]

Most welcome

[@MrTinlokc]

is there any difference for the function of radiocarpal and mid carpal joint?

[@RehabScience]

Yes, while they both contribute to wrist motion, the midcarpal joint is involved more with extension and the radiocarpal joint is more involved in flexion.
