Introduction to Knuckle Pain with Gaming

Are sore and painful knuckles slowing you down or making it hard to game? Repetitive movements, poor grip, and long gaming sessions can lead to pain and stiffness, affecting your performance which can be very frustrating. 

Gaming culture today has changed compared to years past where previously gamers played more leisurely whereas today there is a more competitive mindset. To be competitive this often requires practice and with practice comes more time on the game. This is not a problem if the right measures are taken, however oftentimes we fail to take these measures and balance the arm/hand with rest as well. One common area of pain for gamers is at their knuckles or metacarpophalangeal joints (MCPs). In this article we are going to explore why knuckle pain can happen with gaming, what the likely cause of this is, and how to fix it.

Anatomy of the Hand

The metacarpophalangeal joints (MCP joints) also referred to as your knuckles sit at a key crossroad of where the fingers meet the hand. In this crossroad there are key structures needed to help with the function of gripping a mouse, tapping a key, scrolling a mouse wheel, etc. 

The MCP joint allows for flexion, extension, abduction, adduction, and circumduction of the fingers. Surrounding the joint.

Within the region over the knuckle (MCP joint) lie soft tissue such as tendons and ligaments. Ligaments connect bone to bone and provide the joint with stability. Tendons connect muscle to bone and are often to blame for this knuckle pain as they promote mobility. Throughout the pictures below, tendons can be observed by their white appearance where they then transition to the red muscle lying in the forearm. When we use our hands for gaming our muscles contract in a way to get our fingers to behave how we need them to, such as pressing my fingers to the keyboard as I type this or spamming the L trigger in games. With repetitive use in doing this can cause irritation over the join on the tendon.

Again, there are several tendons that lead into our hand with 6 to be exact that interact with the MCP joint shown here.

1. Palmar side (Button pressing, mouse/controller gripping)
   1. Flexor Digitorum Superficialis
   2. Flexor Digitorum Profundus
   3. Intrinsic Hand Muscles (Lumbricals)
2. Dorsal Side (Top of hand, lifting fingers off of buttons/mouse)
   1. Extensor Digitorum (ED) – (Helps to lift up fingers 2-5) 
   2. Extensor Indicis – (Helps to lift up the index finger) 
   3. Extensor Digiti Minimi – (Helps to lift up the small finger)

Ergonomics

Ergonomics play an important role in anything we do especially when more time is spent doing a particular activity that is repetitive in nature. Mouse and keyboard players rest their wrist such that it is put in slight extension with the fingers resting in slight flexion to then more easily make clicks. Based on this positioning there is now stress on this joint, albeit small amounts of stress, this can accumulate overtime and depending on the intensity of the game or APMs can very quickly cause immense stress on the tendons themselves which can then cause knuckle pain.

Myths

Knuckle Cracking

Now, I know many gamers find themselves cracking their knuckles or have been told in the past not to crack their knuckles as this may cause arthritis and fortunately this just is not based on factual evidence. However if you would like to learn more about what actually happens when you crack your knuckles then, feel free to learn more though our article here on our Esports Health and Performance Institute site.

Arthritis 

Oftentimes when someone is experiencing pain directly over the knuckle they may first make a google search only to discover that it says that arthritis is the culprit. Again, this is likely not true in most cases. This is not to diminish those who do actually have a diagnosis for arthritis however, osteoarthritis is largely an age related disorder where the wear and tear of life and use have resulted in the cause. With most gamers being younger adults this is likely to not be the true cause of pain as prevalence consistently remains around 20% for younger adults.

Causes

Too much stress on your knuckle from gaming.

As mentioned above your knuckle joint can become irritated from repetitive stress of gaming. The muscles may not have enough endurance to handle the repeated clicking and thus the joint takes more compressive stress. The more you game, the more the joint becomes inflamed and irritated. Before I describe the next portion of what is happening – I think it is very important for you to understand how our body works.

Essentially our tissues behave like they have an overheating mechanic where the more stress we place on it by clicking, the closer it comes to overheating. The size of the meter is based on our conditioning (exercising to improve endurance, strength, coordination). At this point your joint (knuckle or metacarpophalangeal joint) is only a small meter and can only handle so much before becoming irritated (overheated).

The next thing we have to realize is that the constant aching or pressure you might be feeling at your knuckle may be an adaptive mechanism from your nervous system. The longer we experience pain, the better our body becomes at producing pain. While it is probably true your METER size is reduced (knuckles can’t handle as much stress), your nervous system is naturally more sensitive because it wants to protect the tissue so it causes the meter to INCREASE more quickly with each “click” SO as an example:

1. Each click before may have raised heat of the meter 4 units
2. But now that you have been dealing with the pain for a while each click raises the heat of the meter 8 units.

Why is this happening? Different factors leading to overuse with knuckle pain in gaming

While there are many ways this can occur, poor wrist & hand conditioning, poor initial ergonomics/posture, and excessive gaming are often the real culprits. It is most commonly these three factors which lead to tissues becoming irritated and weaker.

We often only begin to pay attention to our ergonomics/posture after we feel some aching. We do not realize that in addition to changing this vital component, we have to also work on the conditioning of our wrist/hands (exercise) and monitor our schedule. What often happens is that one or several of these factors were pushed to the side until you began to feel pain – after which you sought out resources to address this issue. Due to the pain (tissue irritation) the joint and the muscles surrounding it became weaker and lost proper coordination.

Even though you may have addressed the posture, the fact that you were not conditioned enough to tolerate your sessions of gaming did not change. You may not have paid attention to your schedule either (how long you were playing without taking a break or stretching in between games) So the bottom line is that..

1. You felt pain
2. Now you have better ergonomics & posture.
3. You are still weak which means you will continue to irritate the joint when you game
4. You may or may not be managing your schedule better and incorporating some stretches in between your games

Ok ok, enough science and whats and whys. Let’s get to how you can address this issue.

How to reduce your Knuckle Pain

I hope it is clear by now that your pain will improve if you address the issues listed above.

1. Proper Wrist Conditioning
2. Better habits around gaming
3. Maintaining proper ergonomics and posture
4. PATIENCE -> TISSUE ADAPTATIONS TAKE TIME.

 

Proper Wrist Conditioning

It is essential in this situation to work on building up our heath meter. We look to perform exercises focused on improving the endurance of the muscles you use to WASD in all of your games. This means the muscles that control your fingers when they press the key down and lift them up. Again, the muscles that actually help to move the fingers first begin at the forearm and cross the knuckle joint. Through fatigue, this can lead to irritation of the joint and this is why they are the primary muscles to focus on with strengthening.

 

 We have created a general injury prevention routine which includes exercises that target these muscles that you can check out here! This is an easy routine you can include either at the beginning or end of the day. As with most endurance/strength building routines you do not want to perform the exercises right before you play (to not fatigue the muscles just before you begin your session). This means it is best to do your exercises 1-2 hours aside from when you plan on gaming or utilizing your hands more frequently. Additionally, I would add some exercises for you to perform on a daily basis to ensure that you build more specific endurance for those muscles

1. Eccentric Wrist Flexion with Finger Curls (3×12, 2-3x/day) To build up endurance
2. Tennis Ball Squeeze 2×10(3-5”), 2-3x/day to increase general grip strength
3. Theraputty Exercises | EXERCISE OF THE WEEK #2

 

Better habits around gaming

This is an important one – but we want to do everything we can with our day to day behavior to promote healthy joints and muscles. This means being mindful about how you are playing and taking breaks at the right time. My general recommendation is to take a 5 minute break every hour to do some stretches which can be found here. Additionally, the exercises shown in these videos can be beneficial for you to alleviate some stress from repeated use. The more you are disciplined with incorporating breaks and stretching into your gaming schedule, the easier the path to recovery will be for this.

 

 

 

Proper Ergonomics and Posture

Both peripheral ergonomics and posture are important to evaluate to prevent any potential contributions to earlier muscle fatigue. If your shoulders are not in the proper position, it can cause the muscles at your forearm to fatigue more easily and irritate the joint in your middle finger earlier. Refer to our guide on posture and ergonomics here.

 

 

Your Knuckle Pain will go away – Be Patient

Being consistent and patient with the recovery process is key. This is the hardest truth for most gamers to swallow. Many gamers may stick with a program for 2-3 weeks, notice only a slight improvement, and then give up. This is one of the largest initial barriers to success. Tissues take time to adapt and develop in strength/endurance. Research shows that it takes roughly 6 weeks for tissues to make a change in strength. This means for the full resolution of a chronic or moderately chronic injury, you need to be consistent with exercises and lifestyle changes for at least six weeks.

 

That’s not to say that it will take six weeks for you to feel any change. Usually, you’ll notice a difference in 1-2 weeks as you have more efficient activation of your muscles and develop more awareness of your body’s limits. The bottom line is you have to remember to be consistent with your exercises and stay on track with your injury treatment program to stay on the road of recovery.

Differential Diagnosis

Trigger Finger

A condition where a finger gets stuck in a bent position and then suddenly snaps straight, like pulling and releasing a trigger. It happens due to inflammation and narrowing of the tendon sheath in the finger on the palm side of the hand directly over this knuckle. Again this is less common in younger adults, however it may be important to understand as it can still occur with gamers or desk workers.

Conclusion

Knuckle pain remains a large frustration for many gamers, however there are real ways to reduce this and prevent it from being as big of an issue. By better understanding our own body and anatomy we can now focus on what is truly relevant in our case. Oftentimes the fix is resolved through management focusing on our posture/ergonomics and our habits focusing on proper stretches and exercises while also being mindful of the intensity and duration that we play. If you’re dealing with pain here or other injuries then consider the troubleshooter program that we developed which provides specific exercises catered toward you and your pain patterns.
