Why Your Hand Stays Closed After Stroke (And Exercises That Help It Open)

本站添加: 2026-05-30

[00:00:00]If you have trouble opening your hand after a stroke, you may assume that this is simply due to [music] muscle weakness. But, there's actually a lot more going on, neurologically speaking.

[00:00:10]I'll explain why this happens and show you some exercises that you can try at home to get your hand open again after a stroke. Your brain [music] and your body are in constant communication. Your brain sort of acts like a referee to keep all of your muscles, including your flexors and extensors, in balance. For the hand, flexors are the to bend your wrist and close your fingers. The extensors help to open the fingers and bring the wrist back. When a stroke damages part of the motor cortex or motor pathways, those that are responsible for movement, the body and the brain are no longer communicating effectively with regards to that movement. And another key thing can also happen. This is when the brain loses its ability to regulate what's called the spinal stretch reflex. Now, typically, this is a protective reflex to keep your muscles from overstretching. If the body thinks that your muscle is overstretching, it sends a signal, your brain interprets, and sends a signal back to contract the muscle to avoid that overstretch. However, if that spinal stretch reflex becomes dysregulated and hyperactive after your stroke, because the brain is no longer able to referee it, it can cause your muscles to contract when they shouldn't be. And this is essentially what causes spasticity. And because the flexor muscles of the arm and the hand are usually more dominant at rest, when you start to develop spasticity, that's when you're going to see the bent elbow, the bent wrist, and the flexed fingers. And I think this is important to point out because you can have spasticity and weakness exist at the same time. You may be experiencing spasticity of the flexors and weakness of the extensors.

[00:01:54]Now, in addition to both spasticity and muscle weakness, there is another thing that can sometimes be at play, making it difficult for you to open your hand again after your stroke. And it's something called learned non-use. When you lost movement and strength out of one of your arms and hands after your stroke, you may have started relying on your stronger side to do things instead.

[00:02:16]And honestly, it makes sense.

[00:02:19]Using your stronger side is probably faster. It's probably less frustrating.

[00:02:24]And it also just helps you to get things done when you're trying to just live your life. But over time, as you leave out your affected arm and hand when you're doing those daily activities, your brain is reinforcing that pattern.

[00:02:38]So it's pruning away pathways to your affected side, and it's prioritizing those pathways going to your stronger side. And this is essentially what boils down to the term learned non-use, where you learn to not use your affected side because it's probably slower and a lot more frustrating. And if you're dealing with learned non-use, which likely happened over the course of months if not years, it can compound whatever spasticity, high muscle tone, or muscle weakness is going on behind the scenes.

[00:03:08]And that's why consistency with the exercises that I'm going to show you today are crucial, because it's actually the mechanism of recovery. We're not necessarily trying to rebuild movement, although we are, but the real goal, the real underlying goal, is to get the brain and the body communicating again. First things first, always check with your doctor or therapist before starting any new exercise or therapy routine, including this one, to make sure that it's right for your specific situation. As with all of my exercises, don't push through pain. So the first level is for survivors who have little to no active movement. So if your hand stays mostly closed, and you don't really have a ton of voluntary active movement yet, your focus right now is going to be to maintain the range of motion that you had and to give your brain some sensory input to tell it that, "Hey, that hand is still there." And the first stretch I want to talk about is a wrist extension stretch. This is essentially where we're just trying to get that wrist bent back.

[00:04:12]We are less concerned with the fingers for this stretch because so often what we see when somebody has a clenched fist, difficulty opening it, is that the wrist is bent. And again, that comes back to that increased flexor tone that we usually see. So, we want to start to counteract that with a very slow, prolonged stretch.

[00:04:31]So, if it's helpful, you can just lay your hand um flat, pinky side down, on a tabletop in front of you. You're going to take your stronger side and just gently wrap your hands around your fist and try to start to bend that wrist back. I'm going to hold it up just so you can see what the movement looks like.

[00:04:50]Now, yours will probably not go as quickly as that, especially if you are dealing with spasticity. Likely, you'll get a little bit of movement. You'll have to hold until that spasticity starts to loosen up. And that's why we try to hold these prolonged stretches for around 90 seconds. And that is because we want to give time for those muscles to relax so that we can ultimately get a little bit more range of motion out of those stretches. Now, the second stretch we're going to talk about is finger extension. This one is going to be a little bit more difficult.

[00:05:24]You may need to modify it based on where you're at. This is essentially just trying to get your fingers back and out.

[00:05:30]But here's the thing, your fingers are probably not going to go into this position.

[00:05:35]So, if you're able to get your stronger hand underneath all of those fingers, you just want to get as much space as you possibly can in between those fingers. So, even if it's the level of space that I'm showing here, if you're able to get a little bit more, but those fingers are still curled, that is totally fine. Just work with where you are, start with what you have, and try to hold up to 90 seconds if you can.

[00:06:01]Again, you can start with 5 seconds, 10 seconds, whatever you're able to do, and build up over time. You can start with around one to two repetitions, working your way up to about three to five repetitions of those 90-second holds.

Now, level two is if you do have some movement returning, but you're still struggling to get those fingers open all the way. So, because we have some active movement in this level, this is really what we want to capitalize on, because active movement is what's going to help drive that brain-body communication. So, I've got two exercises for you at this level, and they're basically just a step up from what we did in level one. And the first is active wrist extension. Again, if we have even just the slightest amount of movement, we want to work on it. So, you can do this in two different positions.

[00:07:01]You can either place your hand with your pinky side down, and try to move your wrist backwards that way, just like this.

[00:07:10]Or, you can hang it off of the edge of a table, and try to bend the wrist up, and then slowly lower back down. The way that I'm showing here is definitely going to be more difficult, because you're essentially fighting the effects of gravity pushing down on your hand.

[00:07:27]So, you just pick the version that fits where you are right now. And just keep in mind, as you lower your hand down, make sure to make that slow and controlled, because that eccentric portion is just as important as the raising up. Now, the second exercise in this level is active finger extension.

[00:07:45]Again, we're capitalizing on the active movement that you have in those finger extensors. So, for this one, you can use your stronger side to hold on to your affected wrist.

[00:07:55]And all you want to do is try to move those fingers up and back as far as you actively can. And you'll see my hand here, I'm not necessarily opening up those fingers hugely. They're not all the way back.

[00:08:08]Just focus on whatever active movement you can and repeat. For both of these exercises, you want to shoot for two to three sets of 10 to 30 repetitions.

[00:08:19]Repetitions are very important when it comes to rebuilding neural pathways. So, you want to make sure that you're being intense, you're being consistent, and that you're doing as many repetitions as you can without pushing through to discomfort or pain. All right, level three is focused on functional movement.

[00:08:36]And this level in particular is for survivors who have got some active wrist extension, some active finger extension, but doing kind of functional daily tasks are still proving difficult because of stiffness and tightness in the hand and the wrist, making it difficult to fully open the hand. And I've got two specific things to practice in this level. And the first is object release practice. Now, this could be anything in your house that you can safely fit into the palm of your hand under your fingers. You could use a balled-up washcloth or a balled-up sock, a small water bottle, whatever works for where your grip is right now. So, the main goal with this is not necessarily on the gripping, but rather on the release portion to get your hand open as far as possible. And sometimes having a more functional object to practice with, whether it's a sock or a washcloth, whatever, is going to be more effective than just doing a rote like grip release exercise.

[00:09:38]And the second thing to focus on is functional tasks. And this just essentially means that you are incorporating your affected hand into more of your daily tasks. And this is going to look very different person to person because every single survivor is going to be at a different place in their recovery. But this might mean that you try to grip and release a coffee mug, grip and release your toothbrush, or even practice holding onto your silverware and releasing while you're eating. Our brain is very interesting in that it also will prioritize tasks that are meaningful and important to us. And doing daily tasks, things that we need and want to get done, are going to signal to our brain, "Hey, let's make this a priority." And in fact, I made a whole video about this phenomenon that you can check out here. Progress with hand movement after stroke is typically very, very slow. And not every survivor is going to regain full wrist and finger extension. And I'm not saying this to be negative. I just want to help you balance expectations. Here's what's also true. No one can predict how much progress you're going to make. The research shows us that there is no ceiling or time limit to stroke recovery. So keep that in mind with every rep that you do because your brain is still capable of change. [music] And nobody gets to tell you where your limit is.
