Lots of EAs I know suffer from some version of Repetitive Strain Injury (RSI), which limits their ability to type. In some cases, people have switched entirely to only using voice commands for controlling their devices, which seems pretty effortful to set up and probably limits their productivity quite a bit.

I have recently developed a mild form of RSI, and am not sure how much time and resources to invest and what types of interventions seem most helpful. I've found it hard to find sufficiently detailed resources on the internet and am interested in learning what others have found most helpful.

I endorse most of Max's recommendations [EA · GW].

Based on my own experience I would definitely recommend being very cautious about RSI, i.e. especially resting carefully, as well as investing in solutions like more ergonomic devices, voice control, reading different resources (e.g. about good posture and different solutions) and visiting physiotherapists and other specicialists. I was largely unable to type or use a computer for 2-3 years due to RSI and I attribute a lot of this not having rested enough early on (despite the fact that I actually did reduce my activity quite dramatically almost immediately upon experiencing symptoms).

Another thing I would note is that although I think it's good to seek help from different experts, I would treat this very critically. I received completely conflicting, but entirely confidently expressed, diagnoses and recommendations from a number of different GPs, physiotherapists and consultant rheumatologists. Some of the literature I read myself also explicitly suggested that tendinopathies tended to be poorly understood by frontline medics, though I'm not in a position to evaluate whether that is the case (or at least true relative to other conditions). Some of the things which were recommended seem to have some evidence suggesting potential for harm (e.g. strengthening exercises, anti-inflammatories and immobilising wrist braces), so there are some grounds for caution.

One of the few things I would recommend that wasn't mentioned in Max's post, so far as I recall, and isn't mentioned in a lot of resources was keeping your hands warm, but I see you mentioned that in your own comment. There also seems to be some evidence that nutrition can be relevant for tendon healing (assuming that your RSI is related to your tendons): see this review. The main things they point to are vitamin C, taurine, vitamin A, glycine, vitamin EA and leucine.

I'm also happy to talk about this 1-1 if you like.

One of the things Max recommends are mobilizations and stretching. While the links he provides explain why mobilizations may be important, they don't actually do that good a job of directly showing you the stretches in a video.

For that, you may want to watch Day[9] demonstrate the stretches people in the StarCraft community use before playing in a professional eSports match or before starting any serious practice session.

+1 to stretching and mobilization, helped for me. Rock climbing helped my partner.

(the best theory I've found so far, but hard to tell if true) Often times muscle injury prevention is helped with teaching your brain/body how to activate the muscle in healthy ways (in addition to rest/stretching/etc). Sometimes much of the problem is your brain/muscles are trying to protect other muscles that are being used poorly, and this compounds (the 'helping' muscles get overworked, and other muscles try to save those ones, etc).

Thanks, very helpful. Especially knowing about your experience (what you said in the first paragraph) seems helpful.

Would love to get some more of that vitamin EA! ;)

Oh dear, I guess I'm too used to always following any capital E with an A automatically.

How did your pain eventually go away, David ?

Some things I've tried and found mildly helpful:

  • Using an ergonomic keyboard (I use a split keyboard, which also helps with back pain)
  • Avoiding typing while feeling cold (this means sometimes wearing a coat at my desk)
  • Wearing a wrist brace at night
  • Adjusting the height of my desk, and using a desk with sufficient depth so I can rest my forearms on it while typing
  • Using my phone with the other hand that isn't affected
  • Generally trying to avoid straining movements with the affected hand (during cooking, etc.)


Things I've considered:

  • Learning touchtyping with the Dvorak layout (or some other alternative layout) – takes ~20h to learn, benefits seem disputed (academic research and lifehackers claim mixed results). Might look into if things don't get better.
  • Using a foot pedal for clicking and modifier keys. Takes some time to learn and set up, though some seemed to like it a lot.

These mostly seem like good things to try. It might be worth experimenting with a number of different ergonomic devices to see which work best for you (which work best seems to be very individual, anecdotally).

Regarding wrist braces: it's been a while since I looked into this, so I don't have a reference to hand and you may be more up to date than I am, but my recollection is that these were recommended for carpal tunnel syndrome, but not for RSI. Fwiw, I would guess that only wearing it at night probably avoids the theorised harms of wearing one (forcing your wrist into unnatural positions and/or leading to weakening of the area) and may still have some benefits, but you'd probably want to look into it yourself (as you may already have done).

Using your other hand for your phone where necessary also seems like a good idea, but I'd be careful about relying on this too much, in case you just injure that hand more too. I think I also used the mistake of trying to use my phone rather than my computer for things too much, despite using my phone being pretty bad for my hands too. It might be worth seeing whether you find a different (e.g. smaller) phone more ergonomic too, since I find that stretching across a large phone can be a strain.

Thank you! :)

One thing that helped a lot for me was  using a keyboard with thumb keys (especially replacing keys where I typically used my pinkies like backspace, enter, cmd/ctrl, and shift). Faster to learn than dvorak and imo a more effective intervention.

I used an Ergodox EZ, there's also Keyboardio, Kinesis, and others.

This feels like an area where our society is insane:  our strongest, most dextrous fingers share A SINGLE KEY on the keyboard.

I found using voice dictation on my phone and iPad pretty good, often now I just send emails and messages using my phone instead of my computer.

I find the Google speech recognition on the Google keyboard for Android pretty good, as well as the Apple speech recognition on IOS devices.

Sample size of 1:

After suffering mild RSI in my early 20s, it was completely and permanently resolved by switching to DVORAK for a year, and then back to QWERTY. It wasn't an intentional solution, but forcing myself to re-learn to type from scratch, twice, massively improved my typing habits. 

Googling around on the benefits of DVORAK for RSI offers more anecdotes in either direction, so take this with a whole pile of salt.

I've had RSI in the past, but not from typing, but instead from repetitive motions loading paper into a machine for scanning. I didn't need to see a doctor about it, and addressing it was ultimately pretty straight forward and I was able to keep doing the job that caused it while I recovered. Things I did:

  • wore a stabilizing wrist brace to alleviate the strain on my wrist that was causing pain, even when I was not engaged in an activity that would necessarily cause pain
  • payed attention to and changed my motions to reduce wrist strain
  • rearranged my work so I had more breaks and less long periods of continually performing the motion (I had other job responsibilities so it was easy to interleave breaks from one thing with work on another)

It's now more than 10 years since I developed RSI, and maybe 4 years since I have needed the wrist brace (my need for it rapidly decreased once I left the job). I think never needing it correlated with increased strength, specifically from indoor rock climbing and related conditioning.

Small change I found useful: Using my small finger or ring finger instead of the index finger when I have to use my laptop touchpad. This way my wrist is less twisted, which before felt uncomfortable after a time.
