    • 00:06When we want to move
    • 00:07our body, we have impulses
    • 00:09that come from our brain
    • 00:11that send signals
    • 00:12down the spinal cord to
    • 00:14the nerves that innervate our
    • 00:16muscles, and
    • 00:17these muscles get a signal
    • 00:18to move.
    • 00:19And when we wanna stop
    • 00:20moving, then the brain stops
    • 00:22the signal and the muscle
    • 00:23is able to relax.
    • 00:25The problem in spasticity
    • 00:27is the brain is telling
    • 00:28that muscle to
    • 00:30contract, to move all of
    • 00:31the time.
    • 00:33Spasticity
    • 00:34is an abnormal firing of
    • 00:36the nerves
    • 00:37and it can happen after
    • 00:39a brain injury or a
    • 00:40spinal cord injury or certain
    • 00:42other neurologic conditions.
    • 00:44And we lose that ability
    • 00:46to relax the muscle and
    • 00:48to relax the motion.
    • 00:50Because of the muscle tightness,
    • 00:51it can cause abnormal positioning
    • 00:53of their arms and
    • 00:55stiffness in their joints that
    • 00:57their joints,
    • 00:58depending on severity, might not
    • 00:59be able to
    • 01:01move at all. Spasticity
    • 01:02can be very limiting to
    • 01:04functional activities, and of course,
    • 01:06there's a range of spasticity
    • 01:07from very mild to very,
    • 01:08very involved.
    • 01:10And so that's why it's
    • 01:11so important to have a
    • 01:13lot of different experts putting
    • 01:14their heads together both to
    • 01:16understand the patient's unique
    • 01:18pattern of spasticity,
    • 01:19but also how that's functionally
    • 01:21impacting them and come up
    • 01:22with treatment plans that will
    • 01:24work for them.
    • 01:25There's absolutely no cookie cutter
    • 01:26approach to spasticity. We have
    • 01:28to treat each patient and
    • 01:29their particular patterns of muscle
    • 01:31spasticity
    • 01:33and their particular goals.
    • 01:34Otherwise, we won't get the
    • 01:36results that the patients are
    • 01:37looking for.
    • 01:43Yale looks at the individual
    • 01:45as a whole.
    • 01:46It's not just one specialist
    • 01:48coming in and looking at
    • 01:50that one part of the
    • 01:51body. Usually, we'll start with
    • 01:53physical or occupational therapy to
    • 01:55really work on the muscle
    • 01:56range of motion and try
    • 01:58and help the muscle relax.
    • 02:00And in cases where we
    • 02:03really understand the affected muscles
    • 02:05and it's not more widespread.
    • 02:08We are able to come
    • 02:09up with tentative
    • 02:10surgical plans for the patients
    • 02:12and then able to test
    • 02:13them in real time,
    • 02:15whether it's nerve blocks or
    • 02:17Botox type treatments.
    • 02:19We have a new therapy
    • 02:21called cryoneurolysis.
    • 02:22We're actually targeting the nerve
    • 02:24that innervates the tight muscle
    • 02:26and reducing the amount of
    • 02:28nerve impulses coming into the
    • 02:30muscle.
    • 02:31So we can see the
    • 02:32impact that nerve based procedures
    • 02:34would have on the extremity.
    • 02:36But it's also amazing because
    • 02:37it lets us uncover
    • 02:39tightness in the joints or
    • 02:41shortness of the muscles, so
    • 02:42we can determine if they
    • 02:43also need more traditional
    • 02:45tendon or joint based surgery.
    • 02:48So they almost get to
    • 02:49see a little bit what
    • 02:50surgery would be like. So
    • 02:52that is invaluable.
    • 02:53And then if you take
    • 02:54that the next step,
    • 02:56having plastic surgery,
    • 02:58nerve surgeon work together with
    • 03:00an orthopedic surgeon brings two
    • 03:02very different
    • 03:03types of training together.
    • 03:06So I'm able to find
    • 03:07the nerve branches to some
    • 03:09of the muscles.
    • 03:10When the nerves are branching
    • 03:11into tiny filaments and entering
    • 03:13the muscle, I'm actually going
    • 03:14and treating the spasticity as
    • 03:16well by taking away eighty
    • 03:17percent of the nerve fibers
    • 03:19to reduce the the tone
    • 03:21and give it a more
    • 03:22normal amount of innovation.
    • 03:25Now what we started doing
    • 03:26is combining those methods with
    • 03:28what's been done historically, what
    • 03:30works for tendon lengthening,
    • 03:32joint fusions, and things like
    • 03:33that. So that we can
    • 03:35target the too much nerve
    • 03:37signal and also
    • 03:38too short a muscle pathway.
    • 03:41The two heads together
    • 03:42actually comes up with a
    • 03:44better result for the patient
    • 03:45and allows us to do
    • 03:46things to maximize
    • 03:47their clinical result.
    • 03:54We also have a team
    • 03:55of excellent therapist and in
    • 03:57our multidisciplinary
    • 03:59clinic, we specifically have an
    • 04:01occupational
    • 04:01therapist.
    • 04:02A lot of the procedures
    • 04:03are getting them into a
    • 04:04better position for function.
    • 04:06So
    • 04:07I'll brace them to make
    • 04:08sure that we maintain that.
    • 04:10And then after that,
    • 04:12we talk about like how
    • 04:14to actually use the function.
    • 04:17What about the wrist?
    • 04:18The wrist seems pointy. Me?
    • 04:20Yes. I love it.
    • 04:23It looks great.
    • 04:24Doing some rehabilitation
    • 04:26post surgery really leads to
    • 04:28better outcomes
    • 04:30and hopefully that the patient
    • 04:31can have lasting results.
    • 04:38You can break it in
    • 04:39so you can touch her?
    • 04:40Not or not body, just
    • 04:42the hand.
    • 04:43Yep.
    • 04:44Yeah. Look at that.
    • 04:46Adults with spasticity
    • 04:48oftentimes have very complicated
    • 04:50medical problems. They've had a
    • 04:51big stroke or they had
    • 04:52a big brain bleed, a
    • 04:53spinal cord injury,
    • 04:55and
    • 04:56there can be so much
    • 04:57focus on life and death
    • 04:59at the beginning
    • 05:00that they get forgotten.
    • 05:02But if we can improve
    • 05:04their comfort, their extremity function,
    • 05:06the ability for folks to
    • 05:07help take care of them,
    • 05:09it can have a profound
    • 05:10impact on them.
