hello misogyners today i'm going to be doing a video on the corvian tennosynovitis
i'm going to show you the finkelstein uh test and a couple of exercises and also show you you know
where the muscles which muscles are involved which is the corvians tenocenovitis is the inflammation
of the tendons of that extensor pollicis brevis and the abductor policy's longest so i'll show
you that anatomy and this is something that's common in people that do repetitive motion like
piano players like carpenters or people that do handiwork at home hammering using drills
massage therapists when we use our thumbs um racket sports new moms it's also common in
new moms where they pick up their baby you know and their thumb you know is abducted
people that lift heavy weights you know put heavy weights against the thumbs so it is common in
people that you know that use their thumbs a lot so i'm going to show you a couple of exercises
to relieve some of that pressure and show you how to save your thumbs because after 33 years
of using heavy duty you know massage work and using my thumbs i've really damaged them and so
now i have the corbin stenocido vita so i wanted to share this video with you and please remember
that this is not for diagnosis this is for information for yourself and for um you know for
your clients that you can make suggestions but we do not diagnose so let's get to it let me show you
okay so now let's talk about the anatomy and i couldn't find my pointer so i'm using my little
screwdriver so bear with me so these are the two muscles that are involved in the corvian
stenosinovitis the extensor pollicis brevis and the abductor pollicis longus
and let me give you a little hint about the the names of the muscles when you see
three words in the names of the muscles it's usually because there's more than one that
you know one short and once long like the extensor pollicis um brevis then there's an extensor
pollicis longus and you can see the tendon right there this these three muscles the tendons here
form the snuff box right here it's an indentation however the extensor pollicis longus is not part
of the decoravian stenosis and the vitus just the extensor pollicis you know brevis and like i said
there's three three words to that name so that means that if there's a brevis there's a longus
and if there's a longus like the abductor policies longest then you know that there's a brevis
so let's talk about where they originate the extensor pollicis brevis originates at the
posterior surface of the of the radius and the interosseous membrane and remember this is the
posterior because you're always referring to anatomical position so an anatomical position
this is the anterior the flexors and these are the extensors this would be the posterior so
that's the reason this is the posterior and they insert on the posterior radius and interosseous
membrane and the um brevis inserts right here all the way to the base of the proximal phalange
this is a distal phalange this is the proximal phalange the thumb remember only has two this
is your your uh your pollux your big toe is your hallux so that's why it's named extensor pollicis
uh brevis because it what it does is it extends the thumb you know it goes from flexion and then
this one extends the thumb now the abductor policy's longest abductor because it abducts
like when you're being abducted by an alien you put your fingers together and it's away
like if you're being abducted by an alien you're being taken away so this is abduction and this is
adduction because you're adding it back so this is abductor pollicis because it moves the thumb and
longest because it's a little bit longer and the insertion is at the base of the first metacarpal
so this one inserts right here where the extensor inserts at the proximal phalange and so now you
know the movements and now you know the anatomy so this is extension and this is ab abduction is away
from the other from the other four fingers now right here you have your flexor retinaculum
the flexoric naculum holds also braces and supports the nine tendons and the median nerves
that go into the carpal tunnel however lots of times with repetitive motion it'll put pressure
on the uh tendon sheaths of the of the uh extensor pollicis brevis and the abductor pollicis longus
so what you want to do is go right here to where the tendon is you know and then you can feel you
can have them your client you know extend and flex so you can feel that tendon let's let me show you
now the finkelstein test so the finkelstein test it's it's better if you do it passive and
active test activists when your client does it and i always suggest my client to do it first because
they know how far to take it and they know how how much it hurts so that way i don't hurt them
what you what they do is they can hold their hand you know support it and against the table
and then close their thumb down like this and then wrap the fingers around it and then do the ulnar
deviation pointing down this really stretches the tendons and that you know the tendon sheaths and
if it's if it hurts then it's a positive you know test for the finkelstein for the uh the
corvian's tennosynovitis now in active that will be the active when the client's doing it a passive
test would be they tuck their thumb in wrap their fingers around it and you move it gently for them
you know this would be the passive test and please be careful because with people that
have you know the the corvian stenosinovitis it's very painful when the you stretch those tendons
so now let me show you a couple of the exercises that will help with this um the the corvians
remember that that the um the extensor retinaculum can put pressure on this tendon sheet so you want
to go to that snuff box right there press right on the tendon sheets and then have them do the
the uh the movements of those muscles so a you know extensor do it 10 times you know
extend their thumb up to 10 times you know this is a good exercise while putting pressure
right there at the flexor retinaculum where the styloid of the radius radius this is the radial
side this is the ulnar side so the stylet of the radius is you know right here so you
they can do this exercise 10 times extending the policies and then now let's do the exercise for
the um abductor pollicis longus remember abd while putting pressure right here you're abducting away
from the other four fingers so they can do this another 10 times okay 10 times another one is
opposition when you go uh your your thumb touches the opposite you know the opposite the pinky
or the base of the pinky you know like this this is another good exercise for the thumb opposition
remember is what differentiates differentiates us us from monkeys because we're able to do these
monkeys are not able to do this so this helps us you know to be able to make tools and to do
texting you know to be able to do gaming opposition that that's being able to do this
that's what opposition means so another exercise that you can do is if they support their hand
you know at home put it on a on a base or something and tuck in the first phalanx and
just open and close ten times ten times and if they can if they're not in as much pain then
they can tuck in both phalanx and close open and close another 10 times so these are very simple
exercises you're engaging the muscles and you're also stretching the tendons you know a little
bit and that really helps to strengthen those muscles and to relieve some of that pressure
oh oh there's also intersection um syndrome and that's usually pain right here in the you know in
the forearm so if they have pain like three to four inches above you know where the um
where the tendon sheets go through that usually right here that's called intersection syndrome
and that's where the muscles intersect so you might want to do you know some massage right here
and work this area because it can radiate you know up remember radiation is usually
you know uh towards the midline of the body and i really want to show you my tools because this is
what has saved my thumbs you know work smarter not harder and after like i said 33 years i've really
damaged my thumbs working on um you know working them all the time so i have these um tools made by
a carpenter they're handcrafted and this is the um the wedge this has really helped me you know you
can go right here even in the origins you know in between the interosseous membrane you can really
get in between those muscles you can work the pollicis you know adductor you can work the base
of the of of the hand also for plantar fasciitis you know go down you know down the the planet part
of the foot for the gliding down the lamina groove for the intercostal so this is a wedge that kind
of helps you get into you know small little areas that you need to you know to work out and the
flat tool is for bigger muscles you know like the trapezius the glutes the hamstrings the quads so
these are for bigger muscles so i use this instead of my thumb now you know i'm working smarter not
harder if you would like to order these you can get them at my website massage therapeutics915.com
and anyway that's that's pretty much the anatomy and the exercises the fingerstein test and this
is all for the corvians tendocinovitus you can recommend that they can they can rest it
ice it and splinting and this is not for diagnosis it's just to help you guys to help you
work smarter not harder so i hope this helps you and until the next time create a great day guys
