Author Topic: Finger Stiffness From Topre Switches (Read 15934 times)

itlnstln · « **on:** Fri, 26 February 2010, 07:39:58 »

Has anyone experienced any finger stiffness from using Topre switches? It seems that since I got my HHKB, I have been waking up with stiff knuckles. It only lasts for a few minutes, but it hurts to make a fist, but once I open and close my had a few times, it's OK. I don't know if it's because the additional tactility switching from Cherry browns is causing me to push harder, thus bottoming out more. Perhaps, since I have used browns for the past year exclusively, my fingers just need to adjust to the new switch and force curve. It doesn't really bother me much during the day, as I keep my fingers moving typing all day, but it does concern me. I really like the HHKB, and I don't want to have to sell it, especially since I can't get a refund, but I also don't want to be causing any long-term injury. My GF would be disappointed if something were to happen to my fingers.

hasn't happened to me yet on the HHKB but had something similar when I was using the filco with white xm's. Typing on that was a workout for the fingers...

Did it go away over time, or is it something that still bothers you?

bigpook · « **Reply #3 on:** Fri, 26 February 2010, 08:19:28 »

It went away within a few days. I had to stop using the XM switches, sadly, they were too much on the fingers.
I have not had that problem with any other keyboard, including the IBM's. The black alps, orange alps and fukka's that I use are fine also.

Weird. I think I will keep after it for one more week. If I still have problems with it after that, I might have to give up on it. I don't want to do any permanent damage.

bigpook · « **Reply #5 on:** Fri, 26 February 2010, 08:27:09 »

how hard are you pounding on the HHKB. IIRC, the cherry browns are pretty close in feel to the Topre; I think the Topre is alot smoother overall though. But neither one requires alot of effort to press.
I remember going to a cherry brown after coming of a BS switch and was just hammering them. It took a few weeks to settle down and learn to go lightly. Even then it didn't hurt my fingers, I created quite the racket though.
Who said browns are quiet? lol

itlnstln · « **Reply #6 on:** Fri, 26 February 2010, 08:36:51 »

I think that's part of the problem. Over my keyboard "history," I have gone from heavier to lighter switches. To me, the Cherry browns feel a little lighter than the Topres, but I believe that's due to different force curve. The tactile point is much sharper in the Topre than the Cherry browns, so I feel like I am getting that "Tug-O-War" effect where I have to use a certain amount of force to push through the tactile point to where I can't stop before bottoming out. I don't feel like I am absolutely pounding the keys, but I am pressing them harder. I do notice that I miss keystrokes from time to time by not pressing hard enough. It could be, too, that I just need to wear these switches in a bit and get them loosened up.

itlnstln,
I would look more at how you are positioning your hands than worry about the switch. Have had a Realforce on my desk for months, and just can't seem to go back to anything else for more than a few hours.

Will do. I think I use a pretty standard position, but I'll make sure I'm not doing anything too weird. On that note, it might be something where this new (and awkard, at times) layout might be putting my fingers in some odd positions. It's mainly my right hand that hurts (the middle knuckle on my fingers), and that hand is in charge of handling the Fn key and the related actions. My left hand hurts less, but it's role is not much different than its role on a regular keyboard layout.

This is why I still would prefer the HHKB3 have arrow keys.

Pretty much.

bigpook · « **Reply #11 on:** Fri, 26 February 2010, 09:29:14 »

I map the function key over on the left hand side. I still do the 'claw' but don't find it to cause any discomfort. I really like not having to move my hand to use the arrow keys.
That and the easy access to page up/down and home/end make it pretty awesome to me.

But to get there I had to put Fnc on the left side.

I got hand pain from the HHKB so I switched over to my homemade Alps board and the pain went away. In my case I don't think it was the layout because it was equally in both hands. But the pain was a dull ache that occurred after extended use, not when waking up in the morning. (I think it's because I'm used to/prefer heavier switches and either was tensing up so I wouldn't bottom out, or was bottoming out too much.) It didn't feel like a long-term-injury-type of pain, but either way, it went away just fine when I switched (no pun intended).

I'm thinking along the same lines as Ripster. I would think that clawing at the arrows might be a possible culprit. If it is indeed pain that you're getting as a result of using the HHKB, then the most repetitive and unusual aspects of HHKB use is what I'd zero in on.

There's a downside to being able to keep your fingers glued to the home row most of the time and it's that you amplify the repetitive nature of some aspects of typing, which is already very repetitive. We have a lot of people here who are really concerned about the loss of efficiency or the potential injuries that you can have from reaching for certain keys, but the flip side of having everything closer is that you hit the same keys more often. Some people may be done in by awkward reaching and some may be done in by cumulative overload.

I'm sure you've used heavier switches before so it seems unlikely that a slight change in the force curve alone will thrash your knuckles unless there was a typing techinque problem in there as well. If it was the force curve alone that was causing you problems due to fatigue, you'd be more likely to get soreness in the muscular webby space right below the base of your knuckles in your hand.

How do you have your keyboard situated? Do you have an adjustable keyboard tray, a keyboard drawer, or is it on a desk? How do you sit at your workstation?

My keyboard is on a desk. The height is right at my elbows, thus when I sit up straight, my upper arm and forearm make a right angle (I usually lean back when I type as it helps keep my wrists straight, and it's comfortable). I have had this setup for about 6 years, now, so I don't think it's the culprit. After reading this dicussion, I am leaning to the new layout as the culprit more so than the switches.

How long have you had the HHKB as your primary keyboard? How many hours a day are you at it?

Did you have any of these symptoms in any manner before you started using the HHKB? Is it something that would occasionally bother you once in a while, but has since bothered you every day since you started using your HHKB?

elbowglue · « **Reply #29 on:** Fri, 26 February 2010, 12:59:30 »

Heres how I see it:
For what it's worth, comparing the topre switch between the cherry brown, the topre's don't "spring back" as much. That is, on the return after a keypress it gives you less force. I found this to be less satisfactory as often I bottom out so I can get a quick rebound and "spring" to move on to the next key. Topre does not support you in doing this as much as cherry browns do.

In this very busy graph below taken from the topre wiki, you can see there is a major difference in force between 2mm and 4mm in the cherry browns vs topre. I assume this is the same for downstroke as well as upstroke. Therefore, when you are deep in the key (beyond the activation point), the topre "rests" more, whereas the cherry brown "pushes back" more. The spring on the topre provides little to no force resistance, and if it does, it only provides it in the first 2mm travel before the switch actuates.

Why do we bottom out in general, why don't we just stop at the actuation point? Well, I think it's because when you are typing faster, you rely on the heavier resistance at the "beyond actuation" point to bounce your finger back to get to the next key quickly.

itlnstln · « **Reply #30 on:** Fri, 26 February 2010, 13:01:07 »

I had no problems before the HHKB, so it's either layout or the switches or a combination of the two. I think another week or two will allow me enough time to get acclimated to the 'board, and if I don't, I'll switch back. That would be pretty disappointing, though.

This is what I was thinking at first; that's why I initially blamed the switch. My reasoning was that since I don't bottom out as much or as hard on the browns, that the more and harder bottoming out I am doing on the Topre was causing some sort of trauma to my fingers, thus the pain in my knuckles. Since I am right handed, and my right hand is stronger, I was causing more trauma in my right vs. my left.

itlnstln · « **Reply #32 on:** Fri, 26 February 2010, 13:11:45 »

Now that I did realize that I mapped Fn to the left Option button, I am going to use that to avoid clawing so much. I am also going to try typing a little softer, too, so I don't slam into the bottom, especially if I don't have to.

bigpook · « **Reply #33 on:** Fri, 26 February 2010, 13:19:18 »

Fn on the left is the only way I can use the HHKB. I think it should be there by default. No idea why they put it on the right side as thats were the arrow keys are. Maybe if I had 6 fingers on my right hand it would work....
I think if you give it a go on the left side you will find it very comfortable. Once you adjust you will find yourself looking for the Fn key on every other keyboard you use and actually get mildly annoyed that you have to move your right hand, all the way over to BFE just to use the arrows keys.
Really, it is annoying.

Well, I also have a Fn on the left, but that is just silly. Put you index finger over an arrow key, and your little finger hovers over Fn.

This is how I use the arrow keys. The left Fn is better for the multikey combos I having problems with earlier this week.

I don't think it's very likely that you'd injure your knuckles from bottoming out for four days unless you have glass hands or are trying to punch the keys through the bottom of the board. Bottoming out is bad because of the excess strain it places on your flexor tendons and muscles in your hand and possible decrease in circulation and increase in inflammatory response that the strains can cause.

This sounds like my symptom from a brown to black keyboard after 2 years on browns. I'd suggest it's the changed key characteristics, not a layout issue: caused by bottoming out, or force curve.

For me it went away (without giving up the new keyboard) within a week, by varying my situation A LOT. I switched mice every night, alternated between 2 different black keyboards, and a brown, and now my pain is all abated.

Maybe there's a penalty (or curse) when you leave Cherry browns after a long time. Maybe brown users are just sensitive and prone to conspiracy theories like ripster said.

elservo · « **Reply #38 on:** Fri, 26 February 2010, 23:57:28 »

I'm of the school of thought that your hands are just getting used to the new claw techniques you're adopting with your new keyboard. I think your right hand just isn't used to making such movements, but now that you're changing fn hands, I bet you that your hand pain will cease.

You guys are all so thorough with everything, and much more knowledgeable, but I just wanted to give a simple explanation. I can say that when I switched from rubber domes to cherry blues, I took a few days before I felt comfortable with it. I typed constantly in order to enjoy the new switches, and I paid for it with a little bit of fatigue and some stiffness, but that's all gone now.

I think it's just a new way of pointing your fingers that is giving your muscles some pain. Keep flexing those fingers and take a lot of breaks. You know you never want to give up those Topres! I certainly wouldn't.
