2A disclaimer
- Im not a medical practitioner
- This talk is for informational purposes only, and
is not intended to diagnose or treat any illness
or disease - Follow my suggestions at your own risk
3Myth 1
- I dont type a lot, so I cant get RSI.
4Myth 1
- I dont type a lot, so I cant get RSI.
- Fact Anyone who types more than two hours a day
is at risk for RSI
5Myth 2
- RSI is mostly psychosomatic
6Myth 2
- RSI is mostly psychosomatic
- Fact Though usually invisible, RSI is a soft
tissue injury susceptible to medical diagnosis
and treatment
7Myth 3
- I dont touch type, so I cant get RSI.
8Myth 3
- I dont touch type, so I cant get RSI.
- Fact though hunt-and-peckers are less likely to
develop RSI, certain habits (such as holding up
the thumbs or making a fist while typing) can
cause serious ailments
9Myth 4
- Carpal tunnel syndrome is the most common kind of
RSI
10Myth 4
- Carpal tunnel syndrome is the most common kind of
RSI - Fact CTS is actually one of the rarest forms of
RSI, and its over-diagnosis and over-hyping can
be a barrier to effective treatment for RSI
patients
11Myth 5
- My symptoms have been like this for years, so I
guess it wont get any worse.
12Myth 5
- My symptoms have been like this for years, so I
guess it wont get any worse. - Fact RSI is progressive, and even if the pain
doesnt get worse, permanent disability is
possible if the injury gets bad enough
13Myth 6
- If my hands get really bad, I can always switch
to voice dictation until it gets better.
14Myth 6
- If my hands get really bad, I can always switch
to voice dictation until it gets better. - Fact Current voice dictation systems are a poor
substitute for the keyboard, especially for
technical workers
15My story
- Binge typing
- Poor posture and awful ergonomics
- Years of incremental adjustments
- Denial
- Finally, a scare
16A week of terror
- inability to type
- excruciating pain
- soreness and heaviness
- clumsiness
- hyperawareness an injured feeling
17Im going to fix this!
- Appt. w/doctor
- Braces
- Voice dictation
18Down and dirty with dictation
- Training
- and frustration
- I dont do Windows!
- more frustration
- How do you pronounce s/\S()/1.old/?
- even more frustration
19A demonstration
- Dragon NaturallySpeaking Professional
- Only available from certain consulting vendors
- Teen, Standard or Preferred wont work
- conversational speech system
- This laptop
- 300 MHz Intel Celeron
- 96MB RAM
- How itll work
- (Its going to be excruciating)
20Troubles in voice-land
- Passwords?
- Curses/cbreak programs are dangerous
- Many GUIs dont work well with speech
- The command line is doable, but hard
- X is near impossible
- Errors
- Discrete systems are better except when theyre
worse - Laryngitis is an RSI
21A disturbing prognosis
- Diagnostics
- The Poking Test
- The Prodding Test
- The Shocking Test
- The Numbing Test
- So what is it, anyway?
- Treatment braces -- and maybe surgery
- Did you say permanent???
22A friend steps in
- Pascarelli Quilter, Repetitive Strain Injury
(John Wiley Sons, 1994) - I do a lot of self-education
23What is RSI?
- Repetitive Strain Injury
- RSI ! Carpal Tunnel Syndrome
- Umbrella term for Cumulative Trauma Disorders
(CTD) stemming from hand movements that are - prolonged
- repetitive
- forceful
- awkward
24What does RSI affect?
- Involves damage to
- muscles
- tendons
- nerves
- In the areas of
- neck
- shoulder
- arms
- hand
25What does RSI feel like?
- Great variability between sufferers, but commonly
reported symptoms include - Pain
- acute (stabbing) or chronic (soreness)
- shooting or localized
- brief or long-lasting
- Weakness
- Numbness or other neurological symptoms (referred
pain, etc.) - Motor impairment (clumsiness, etc.)
26Warning signs of RSI
- Pain during typing
- Difficulty with ordinary chores
- Opening doors with shoulders or feet
- Stiffness, weakness, or lack of endurance
- Heaviness
- Lack of coordination, dropping things
- Cold hands
- Hyperawareness of hands
- Frequent self-massage or cracking
27Causes of RSI
- Repetition
- Ignorance of proper use of the hand
- Poor posture
- Holding still
- Being out of shape
- Forced speed
- Overwork
- Excessive monitoring
- Lack of job satisfaction
28RSI isnt a fracture
- RSI is a soft tissue injury, so
- it comes on very slowly
- it takes a long time to heal
- rest alone will not affect recovery
- it rarely comes back to 100
- relapses are par for the course
- endurance is the last thing to return
- symptoms poorly differentiatea successful
treatment of one ailment often reveals other
undiscovered ones
29Types of RSI
- Muscle tendon disorders
- Cervical radiculopathy
- Epicondylitis ganglion cysts
- Tunnel syndromes
- Nerve circulatory disorders
- Other associated disorders
30Muscle tendon disorders
- Muscle and tendon disorders
- Myofascial damage
- Tenosynovitis
- Stenosing tenosynovitis

34Tunnel syndromes CTS
- Tunnel syndromes involve three nerves
- median (middle)
- radial (thumb side)
- ulnar (pinkie side)
- Median nerve -- Carpal Tunnel Syndrome
- Dynamic (RSI)
- Passive (rheumatoid arthritis, gout, diabetes,
hypothyroidism, etc.)
35CTS is rare
- Carpal tunnel syndrome is one of the rarest forms
of RSI - 15 of office workers have some form of RSI
- lt 1 have CTS
- So why is it so prevalent in discussion?
- Obvious treatment options
- Medically less controversial
- Profitable for surgeons
36Radial and ulnar tunnel syndromes
- Radial Tunnel Syndrome
- Ulnar Nerve Disorders
- Sulcus Ulnaris Syndrome
- Cubital Tunnel Syndrome
- Guyons Canal Syndrome
37Nerve circulatory disorders

- Focal Dystonia (writers cramp)
- Osteoarthritis
- Fibromyalgia
- Dupuytrens Contracture
39I take control
- Get rid of the braces
- Insist on a better diagnosis
- Abort the path towards surgery
- Start aggressive physical therapy and bodywork
40The traditional medical team
- General, family or adult practitioner
- Physical therapist(s)
- Specialists
- Orthopedist
- Hand surgeon
- Neurologist
- Occupational/sports medicine doctor
- Physiatrist
- Rheumatologist
- Pain management specialist
41The alternative medical team
- Massage therapist(s)
- neuromuscular therapy
- Swedish or shiatsu
- Rolfing or Hellerwork
- Feldenkrais
- Osteopath or chiropractor
- Acupuncturist

- ibuprofen or fenoprofen
- Butazolidin, Indocin, Voltaren
- Pain medication
- OTC aspirin, acetaminophen
- Painkillers codeine, Perkocet, hydrocodone
- Cortisone
43Splinting
- Splints are controversial
- Often indicated for CTS or DeQuervains syndrome
- NEVER use them while typing!!!
- Braces arent much better
44Surgery
- Is it really necessary?
- Is surgery efficacious for this condition?
- Have all nonoperative techniques been eliminated?
- Is it a quick fix?
- Get a second opinion (and a third, and a fourth)
45Physical Therapy
- Deep-tissue massage
- Phonophoresis
- Iontophoresis
- Ultrasound
- Transcutaneous electrical nerve stimulation
(TENS) - Upper body exerciser (UBE) machine
- Neuromuscular stretches
46Occupational Therapy
- Work hardening is a no-no for RSI
- Posture retraining
- Preventative exercise
- Stretching
- Strengthening
47Alternative therapies
- Acupuncture
- Spinal manipulation
- Massage therapy
- Vitamins
- Yoga
48What not to do
- Dont self-diagnose!
- Dont exercise without the advice and consent of
your practitioner - Dont rush to surgery
- Dont look for an easy way out
- Dont let your doctor talk you into treatment
options you dont want - Dont fall for ergonomic gimmicks
49Your recovery
- Stop (or at least reduce) the injurious behavior
- See a doctor trained in soft-tissue injuries
- Start medical treatment
- Investigate alternative care, if appropriate
- Develop new long-term work and living habits
- Develop a maintenance plan (exercise and massage)
50First step stop hurting yourself
- Take a break
- Take the day off
- Take vacation
- Take disability leave
- Take unemployment
- Whatever it takes -- dont let RSI become
something worse - Permanent disability can set in within weeks or
months if you dont do something now
51But is it really that serious?
- It is, if you experience any of the following
- Pain
- bad enough to bring tears
- that doesnt go away with a break, that you go to
bed with, or wake up with - that wakes you up at night
- that changes your daily routine
- Neurological symptoms
- Clumsiness, or an out of control feeling
- Numbness or paralysis
52Rest
- Refers to the temporary cessation of injurious
behavior, not to stopping activity with the
injured part entirely - Gentle motion is necessary
- Therapy begins during the rest period
53Patience!
- RSI takes a long time to heal
- Endurance is the last thing to return
- Keep a log
54Living and coping
- Reduce and improve overall hand and arm use, not
just typing - Take frequent breaks
- Pay attention to the signals your body is giving
you
55I learn to live
- Services, services, services!
- You dont look injured.
- The bag, the book, and the handshake
- Dealing with doors
- Flex those schedules!
56Prioritize
- What uses of your hands are really important to
you? - Work
- Household chores
- Driving
- Recreation
- Find ways to eliminate or reduce the less
important ones
57Dealing with flare-ups
- Ice
- Heat
- Frequent breaks
- Stretches
58Ergonomics 101
- Goal free, effortless movement of body
- Everyone is different
- The injurious positions
- pronation
- ulnar deviation
- dorsiflexion
- Tense, constrained movements are never good, no
matter how correct - Even the best positioning needs to be changed
frequently
59Ergonomics 101
- Get your chair up!
- Get your keyboard down!
- Put down those kickstands!
- Get rid of your wrist rest (for awhile)
- Keyboards are bad
- Mice are worse
- Trackballs are awful
- Adjustability is essential
60The keyboard
- Fancy keyboards arent always the best
61Ergonomic keyboards
- Comfort Keyboard
- too adjustable?
62Ergonomic keyboards
- Microsoft Natural
- Not adjustable
- Requires radial deviation
- Forward tilt is good
63Ergonomic keyboards
- IBM Options
- separate pieces allow for infinite adjustability
- but discontinued...
64The mouse
- An ergonomic nightmare
- Options to think about
- Cordless mouse
- New Microsoft Intellimouse
- Avoid using the mouse whenever you can
65Alternate pointing devices
- Trackballs are bad
- Graphic tablets are pretty good
- Avoid pronation, dorsiflexion and ulnar deviation
66An example of bad ergonomics
- Logitech Trackman Marble FX
67What about laptops?
- You can use a laptop ergonomically
- Lighter vs.. bigger keyboard
- Move around!
68Ergonomic furniture 101
- The table
- The chair
- The keyboard tray
69The table
- Sit/stand stations are the best
- Flat if you have a keyboard tray
- Sectioned if you dont
- Easy resetting to presets
- Does it float?
70The chair
- Height
- Forward tilt
- Lumbar support
- Armrests
71The keyboard tray
- Get one
- Evaluate knee clearance
- Adjust it carefully for best results, get an
ergonomist to do it for you - Non-adjustable trays are unacceptable and
ergonomically the same as a fixed table - If your table is sufficiently adjustable, you can
use it instead - Does it hold your mouse too?
72The ideal ergonomic setup (IMHO)
- Good chair
- Flat sit/stand station
- Keyboard tray w/mouse pad
- Graphics tablet
- LCD screen
73Random ergonomic nostrums
- Wrist rests
- Forearm rests
- Cording keyboards
- Weird input devices
