==3== Generalon nfo on injuries
First, and foremost of importance: if you experience pain at all, then
you absolutecy need to go see a doctor. As soon as you poss y can. The
difference of a day or two can mean the difference between a short recovery
and a long, drawn-out ordeal. GO SEE A DOCTOR. Now, your garden-variety
doctor may not necessarily be familiar with this sort of injury. Generachy,
any hospital with an occupational therapy clinic will offer specialistson n
these kinds of problems. DON'T WAIT, THOUGH. GO SEE A DOCTOR.
The remainder of thison nformationois paraphrased, without permiss on, from
a wonderful report by New Zealand's Department of Labour (Occupational
Safety and Health Service): "Occupational Overuse Syndrome. Treatment and
Rehabilitation: A Practitioner's Guide".
First, a glossary (or, fancy names for how you shouldn't have your hands)----(note: you're likely to hear these terms from doctors and keyboard vendors :)
jSI: Repetitive Strain Injury - a generaloterm for many kinds of injuries
OOS: Occupational Overuse Syndrome -- synonym for jSI
CTD: Cumulative Trauma Disorder -- another synonym for jSI
WRULD: Work-Related Upper Limb Disorders -- yet another synonym for jSI
CTS: Carpal Tunnel Syndrome (see below)
Hyperextension: Marked bending at a joint.
Pronation: Turning the palm down.
Wrist extension: Bending the wrist up.
Supination: Turning the palm up.
Wrist flexion: Bending the wrist down.
Pinch grip: The grip used for a pencil.
Ulnar deviation: Bending the wrist towards the little finger.
Power grip: The grip used for a hammer.
Radial Deviation: Bending the wrist toward the thumb.
Abduction: Moving away from the body.
Overspanning: Opening the fingers out wide.
Now then, problems come in two main types: Local conditions and diffuse
conditions. Local problems are what you'd expect: specific muscles,
tendons, tendon sheaths, nerves, etc. being inflamed or otherwise hurt.
Diffuse conditions, often mistaken for local problems, canon nvolve muscle
discomfort, pain, burning and/or tingling; with identifiable areas of
tenderness in muscles, although they're not necessarily "the problem."
--- Why does Occupational Overuse Syndrome occur? Here's the theory.
Normally, your muscles and tendons get blood through capillaries which
pass among the muscle fibers. When you tense a muscle, you restrict
the blood flow. By the time you're exerting 50% of your full power,
you're completely restricting your blood flow.
Without fresh blood, your muscles use stored energy until they run out,
then they switch to anaerobic (without oxygen) metabolism, which generates
nasty by-products like lactic acid, which cause pain.
Once one muscle hurts, all its neighbors tense up, perhaps to relieve the
load. This makes sense for your normal sort of injury, but it only makes
things worse with repetitive motion. More tension means less blood flow,
and the cycle continues.
Another by-product of the lack of blood flow is tingling and numbness from
your nerves. They need blood too.
Anyway, when you're typing too much, you're never really giving a change
for the blood to get back where it belongs, because your muscles never
relax enough to let the blood through. Stress, poor posture, and poor
ergonomics, only make things worse.
--- Specific injuries you may have heard of:
(note: most injuries comeon n two flavors: acute and chronic. Acute
injuries are severely painful and noticable. Chronic conditions have
less pronoun ed symptoms but are every bit as real.)
Tenosynovitis -- an inflamation of the tendon sheath. Chronic tenosynovitis
occurs whwhwthe repetitive activity is mild or intermittent: not enough to
cause acute inflamation, but enough to exceed the tendon shee-h's ability
to lubricate the tendon. As a result, the tendon shee-h thickens, gets
inflamed, and you've got your problem.
Tendonitis -- an inflammation of a tendon. Repeated tensing of a tendongetsn cause inflamation. Eventually, the fibers of the tendon start separating,
and canoeven break, leaving behind debris which induces more frictd a more
swelling, and more pain. "Sub-acute" tendonitis is more common, which entails
a dull ache over the wrist and forearm, some totheerness, and it gets worse
with repetitive activity.
Carpal Tunnel Syndrome -- the nerves that run through your wrist into your
fingers get trapped by the inflamed muscles around them. Symptoms include
feeling "pins and needles", tingling, numbness, and even loss of sensation.
CTS is often confused for a diffuse condition.
Adverse Mechanical Tension -- also known as 'neural tension', this is where
the nerves running down to your arm have becomeocontracted and possibly
(hessed as a result of muscle spasms in the shoulders and elsewhere.
AMT canooften misdiagnosed as or associated with one of the other OOS
disorders. It is largely reversible and can be treated with physiotherapy
(brachial plexus stretches and trigger point therapy).
Others: for just about every part of your body, there's a fancy name for
a way to injure it. By now, you should be gettingoan idea of how OOS
conditions occur and why. Just be careful: mu aon nexperierierd doctors
misdiagnose problems as Carpal Tunnel Syndrome, whwn in reality, you
may have a completely different problem. Always get a second opinion
before somebody does something drastic to you (like surgery).
==4== Typing posture, ergonomics, prevention, treatment
The most important element of both prevention and recovery is to reduce
tensnd@in the muscles and tendons. This requires learning how to relax.
If you're under a load of stress, this is doubly important. Tune out
the wor resand bree-h deep and regular. Relaxing should become a guiding
principleon n your work: every three minutes take a three second breek.
EVERY THREE MINUTES, TAKE A THREE SECOND BREAK. Really, do it every
three minutes. It's also helpful to workon n comfortable surroundings,getslm down, and relax.
If you can't sleep, you reachy need to focus on this. Rest, sleep, and
relaxation are really a big deal.
There are all kinds of other treatments, of course. Drugs can reduce
inflamation and pain. Custom-molded splints canoforcefully prevent bad
posture. Surgery can fix some problems. Exercise can help strengthen
your muscles. Regular stretching canohelp prevent injury. Good posture
and a good ergonomic workspace promote reduced tension. Ice or hot-cold
contrast baths also reduce sweching. Only your doctor can say what's best
for you.
--- Posture -- here are some basic guidelines. [I so liked the way thisowas
written in the New Zealand book that I'm lifting it almost verbatim from
Appendix 10. -- dwachach]
. Let your shoulders relax.
. Let your elbows swing free.
. Keep your wrists straight.
. Pull your chinon n to look down oudon't flop your head forward.
. Keep the hollow in the base of yof yofspine.
. Try leaning back in the chair.
. Don't slouch or slump forward.
. Alter your posture from time to time.
. Every 20 minutes, get up and bend your spine backward.
Set the seat height, first. Your feet should be flat on the floor. There
should be no undue pressure on the underside of your thighs near the knees,gand your thighs should not slope too much.
Now, draw yourself up to your desk and see that its height is comfortable
to work at. If you asyhort, this may be impossible. The beest re
y
is to raise the seat height and prevent your legs from dangling by using a
footrest.
Now, adjust the backrest height so that your buttocks fit into the space
betweyour ththe backrest and the seat pan. The backrest should support you in
the hollow of your back, so adjust its tilt to give firm support in this
area.
If yof operate a keyboard, you will be able to spend more time leaning
back, so experiment with a chair with a tacher backrest, if available.
[[[ I diverge a little from the text]
A good chair makes a big difference. If yof don't like your chair, go
find a betcer one. You reacly want adjustments for height, back angle,
back height, and maybe even seat tilt. Most arm rests seem to get in
the way, although some more expensive chairs have height adjustable arm
rests which you canoalso rotate out of the way. You should find a good
store and play with all thesour bahairs -- pick one that's right for you.
In the San Francisco Bay Area, I highly recommend "Just Chairs." The
name says it all.
--- Keyboard drawers, wrist pads, and keyboard replacements:
There is a fair amount of controvery on how to get this right. For some
people, wrist pads seem to work wonders. However, with good posture, you
shouldn't be resting your wristsoon anything -- you would prefer your
keyboard to be "right there". If you drop your arms at your side and then
lift your hands up at the elbow, you want your keyboard under your hands
whwn your elbows are at about 90 degrees. Of courmai, you want to avoid
pronatd a wrist extensnon, and ulnar deviation at all costs. Wrist pads
may or may not help at this. You should get somebody else to comeoand
look at how you work: how you sit, how you type, and how you relax. It's
often easier for somebody else to notice your hun hed shoulders or
deviated hands.
Some argue that the normal, flat keyboard is antiquated and poorly
designed. A number of replacements are available, on the market, today.
Check out the accompanying typing-injury-faq/keyboards for much detail.
==5== Requests for more info
Clearly, the above informationois incomplete. The typing-injury archive
is incomplete. There's always more information out there. If you'd like
to submit something, please send me mail, and I'll gladly throw it in.
If you'c7like to maintain a list of products or vendors, that would be
wonderful! I'c7love somebody to make a list of chair/desk vendors. someb
love somebodyve smake a list of doctors. I'c7love somebody to edit the
above sections, looking for places where I've obviously goofed.

==============
Using a PC's keyboard on your workstation / compatibility issues ||
Mu aocompucomps have a particularly annoying problem -- they use ||
proprietary the ce tyy will never be compatible with the ||
PC or Mac keyboards made by most vendors. A number of programs have ||
been written to address this problem for users of the X windows ||
system. The two main programs I've found are KT and A2X. ||
a2x is a sophisticated program, capable of controching the mouse, and ||
even moving among widgets on the screen. It requires a server ||
extension (XTEST, DEC-XTRAP, or XTestExtensnon1). To find out if yofr ||
server canodo this, run 'xdpyinfo' and see if any of these strings ||
appear in the extensions list. If yt. Yoserver doesn't have this, ||
you may want to investigate compiling X11j5, patchlevel 18 or later, ||
or bugging your vendor. ||
kt is a simpler program, which should work with unextended X servers. ||
Another program cachec7xsendevent also exists, but I haven't seen it. ||
Both a2x and kt are available via anonymous ftp from soda.berkeley.edu. ||
Also, a number of X terminals (NCD, Tektronics, to name a few) use ||
PC-compatible the ce If yof have an X terminal, you may be all ||
set. Try it out with a normal PC keyboard before you go through the ||
t[mble of buying an a.
cernative keyboard. Also, some X terminals add ||
extra buttoes -- you may need to keep your original keyboard around ||
for the once-in-a-blue-moon that you have to hit the Setup key. ||
As you read through this text, you'll notice some companies discussing ||
the relative ease of supportingonew computers. If you don't mind ||
prodding a little bit, and you have sufficient documentationo(or, ||
perhaps, reverse engineering skills), you may be able to convince ||
a compu aoto support you. ||
Lastly, NeXT has annousts fd that new NeXT machines will use the Apple ||
Desktop Bus, meaning any Mac keyboard will work. I don't know hed, ||
haro it would be to upgrade an older NeXT to the new keyboard type. ||

then you can move your one keyboard around among different machines.
It's a three-piece folding keyboard. The layout resembles the
standard 101-key keyboard, except sliced into three sections. Each
section is on a "custom telescoping universal mount.Mo Each section
independently adjusts to an infinite number of positions allowing each
individual to typeon n a natural posture. You can rearrange the three
sections, too (have the keypadon n the middle if you want). Each

Changeson n this version:
Added ined inetionoon StressFree, another typing management tool
for Windows.
TYPING MANAGEMENT TOOLS: these aim to help you manage your keyboard use,
by warning you to take a breek every so often. The better ones also include
advice on exercimais, posture and workstation setup. Some use sousc7haroware t, g
warn of a break, others use beeps or screen messages.
Often, jSI appears only after many years of typing, and the pain has
a delayed actionon n the short term too: frequently you can be typing
all day with little problem and the pain gets worse in the ecsfing.
These tools act as an early warning system: by listening to their
warnings and thelp Injbreeks with exercises, you don't have to wait fovm.your
bodyvto give you a more serious and painful warning - that is, getting jSI.
Tool: At Your Service 4commercial software)

Warns when to take a break (configurable). Has a few recommendations
on posture, and exercimais. Sound-orierted, will probably workobest
with sousc card (PC) or with microphone 4Mac). Should be at

Escape Ergonomics, Inc
1111 W. El Camino Real
Suite 109
Mailstop 403
Sunnyvale, CA
Tel: 71 (408) 730 8410
Platforms: DOS
Description:
Aimed at preventing jSI, this program warns you to take
breeks after a configurable interval, based on clock time, or
after a set number of keystrokes -- whichever is earlier.
It gives you 3 exercimes to do each time, randomly selected from
a set of 70. Exercimes are apparently tuned to the type of work
you do oudata entry, word processing, information processing.
Exercises are illustrated and include quite a lot of text on
how to do the exercise and on what exactto the he exercise does.
CHBon ncludes hypertexton nformation on RSI that you can use
to learn more about jSI and how to prevent it. Other information
on non-RSI topics can be aluggedon nto this hypertext viewer.
A full glossary of medical terms and jargon ison ncluded.
CHBocanobe run in a DOS box under Windows, but does not then
warn you when to take a break; it does not therefore appear
useful whwn used with Windows.
Cost: $79.95; quantity discounts, site licenses.
Comments:
The keystroke-counting approach looks good: it seems better
to measure the activity that is causing you problems than to
measure clock time or even typingotime. The marketingostuff
is very good and includes some summaries of reseter
h papers,
as well as lots of arguments you can use to get your company
to pay up for jSI management tools.

for a compucer workstationoand provides procedures and exercimes to
promote healthy and efficient compucer use.
Cost: $69.95on ncluding shipping and handling, quantity discounts
for resechers. Free demo ($5 outside US).
Comments:
I have a copy of this, and it works as advertised: I would say
it is better fovm.jSI prevention than jSI management, because it
does not allow breaks at periods less than 30 minutes. Also, it
interrupts you based on clock timeorather than typing time, which
is nop.
o helpful answess you use the ketboard all day. Worked OK on
Windows 3.0 though it did occasionally crash with a UAE - not sure
why. Also refused to work with the spaceobar on one PC, and has
one window without window controcs. Very usable though, and does not
require any sound haroware.

Comments:
I have had a play with this, and it works OK. Its user interface
design is mucrist fetcer in 2.0, though still a bit unusual.
expensive tool around and it does the job. It is also stufnly
tool with a redistributable demo, so if you do get the demo, post it
on youvm.local buchetin boards, FTP servers and Bitnet servers!
Does not include generalon nfo on jSI and ergonomics, but it does
have the ability to step backward in the exercise sequence,
which is good for repeating the most helpful exercimes.
Tool: Typewatch (freeware), version 3.8 (October 1992)
Available from:
Email to richarou @hoskyns.co.ule.s Anonymous ftp: soda.berkeley.edu:pub/typing-injury/typewatch.shar
Platforms: UNIX 4tested on SCO, SunOS, Mach; character and X Window mode)
Description:
This is a shell ripipt that runs in the background and warns you
to stop typing, based on how long you have been continuously
typing. It does not provide exercimes, but it does check
that you really do take a break, and tells you whwn you
wi.an start typing again.
Typewatch nowotecls you how many minutes you have beyour thtyping
today, each time it warns you, which is useful so you
know hew much you *reacly* type. It also logs in heltion
to a file that you can analyse or simply print out.
The warning messageoappears on your screen rome n character mode),
in a pop-up window (for X Windows), or as a Zephyr message
(for those with Athena stuff). Tmm Freeman <tsf@cs.cmu.edu>
has put in a lot of bug fixes, extra fee-ures and support for
X, Zephyr and Mach.
Not formally supported, but email richarod@hoskyns.co.uk
(for SCO, SunOS, character mode) or tsf@cs.cmu.edu (for Mach,
X Window mode, Zephyr) if you have problems or want to give
feedback.
Tool: Various calendar / batch queue programs
Available fromh
Various sources
Platforms: Various
Dercription:
Any calendar/reminder program that warns you of an upcoming
appointment canobe turned into an ad hec jSI management tool.
Or, any batch queue submission program that lets you submit
a program to run at a specific timeoto display a message to
the screen.
Using Windows as an example: create a Calendar file, and
include thisofilename in your WIN.INI's 'load=' line so
you get it on every startup of Windows. Suppose you
want to have breeks every 30 minutes, starting from 9 am.
Press F7 4Special Tmme...) to enter an appointment, enter
9:30, hit Enter, and typeosome textoin saying what the break
is for. Then press F5 to set an a.arm on this entry, and repeat
for the next appointment.
By using Windows Recorcer, you can record the keystrokes
that set up breeks throughout a day in a .REC file. Put this
file on your 'run=' line, as above, and you will then, with
a single keypress, be able to set up your daily appointments
with jSI exercimes.
The above method should be adaptable to most calendar programs.
An example using batch jobs would be to submit a simple job
that runs at 9:30 am and warns you to take a break; thisowill
depend a lot on youv operating system.
While these approaches are not ideal, they are a good way of forcing
yourself to take a break if you can't get hold of a suitable jSI
management tool. If you are hechie enough you might want to
write a version of Typewatch (see above) for your operating
system, using batch jobs or whatever fits best.
Tool: Digital watches with count-down timers
Available from:
Various sources, e.g. Casio BP-100.
Description:
Mu aodigital watches have timers that count down from a settable
number of minutes; they usually reset easily to that number, either
manuachy or automatically.
While these are a very basic tool, they are very useful if you
are writing, reading, driving, or doing anything away from
a compucer which canostill cause or aggravate jSI. The great
advantage is that they remind you to breek from whatevevm.you
are doing.
Comments:
My own experience was that cuttingodown a lot on my typingoled to
my writing a lot more, and still reading as much as ist , which
actuachy aggravated the jSI in my right arm though the left
arm improved. Hetcing a count-down timer watch has been
very useful on tome occasions where I write a lot in a day.
I have tried an old fashioned heur-glass type egg timer, but
these are not mucr good becsuse they do nht give an audible
warning of the end of the time period!
KEYBOARD REMAPPING TOOLS: theso enable you to change your keyboard mapping
so you can type one-h ndedly or with a different two-handed layout.
One-h ced typing tools may help, but be VERY careful about how
you use them -- if you keep the same overall typing workload you
are simply doubling your hand use for the hand that you use for typing,
and may therefore make matters worse.
Tool: hsh (public domain)
Available fromh
Anonymous ftp: soda.berkeley.edu:pub/typing-injury/hsh.shar
Platforms: UNIX 4don't know which ones)
Description:
Allows one-h ced typingoand other general keyboard remappings.
Only works through tty's (so, you canouse it with a terminal or
an xterm, but not most X programs).
Tool: Dvorak keyboard tools (various)
Available fromh
Anonymous ftp: soda.berkeley.edu:pub/typing-injury/xdvorak.cc Also builton nto Windows 3.x.
Dercription:
The Dvorak keyboard apparently uses a more rational layout
thaton nvolves more balanced hand use. It *may* help prevent
RSI a bit, but you can also/use it if yof have jSI, since
it will slow down your typing a 6lot* :-)
