What is carpal tunnel syndrome?

Carpal tunnel syndrome (CTS) is a repetitive stress disorder that strikes millions of people around the world – especially those who perform tasks repetitively for long periods of time without interruption.

The carpal tunnel is a small passageway in the hand that contains several important nerve endings and tendons.  CTS occurs when the median nerve – which is found in the carpal tunnel and controls feeling and movement in the forefinger and thumb - is swelled and pressed or pinched against the wrist.  This pressure causes weakness, numbness and pain in the hand-wrist area.

Common symptoms of carpal tunnel syndrome include:

• Burning or tingling sensations in the palm or fingers
• Itching in the palm or fingers
• Feeling as if the hands are swelling up, even though they are not.
• Inability to grip objects or make a closed fist

Myths and facts about who is at risk for Carpal Tunnel Syndrome?

As a well-worn part of the lexicon, there is a great deal of misinformation floating around about carpal tunnel syndrome.  The following separates common myths from facts.

Myth: Data-entry workers are at the greatest risk for getting CTS

Fact: While data-entry and other computer related tasks do have a relatively high incidence of CTS on the job, those who work on the assembly line putting together products are actually at the highest risk for the illness.  Other jobs commonly associated with CTS are: sewing, fish packing, fish cleaning and meat packing.

Myth: Men and women are equally likely to get carpal tunnel syndrome

Fact: Because the size of the female carpal tunnel is smaller, and therefore more susceptible to swelling and blockage, women are actually three times more likely to get CTS than men.

How to avoid Carpal Tunnel Syndrome

There are a variety of simple ways to keep CTS at bay.  It is important to take part in the following activities BEFORE carpal tunnel syndrome becomes a problem.  Preventative procedures include:

• Sit with good posture during work hours (or stand up straight if the job does not allow sitting)
• Purchase wrist guards, ergonomic keyboards and other devices when performing long stretches of data entry.
• Take frequent breaks throughout the workday.  Do not work longer than an hour to an hour and a half without a short five minute break.
• Performing proper stretching exercises throughout the work day.
  • Wrist stretching - Place your forearm on a desk or table with wrist lying off of the edge, palm down. Bend hand downward as far as possible without experiencing discomfort, then upward. Repeat five times
  • Neck stretch – Can be performed standing or seated.  With your head facing forward, tilt the head down towards the shoulder as far as you can and hold that position for five seconds.  Now repeat by moving the head towards the left shoulder.  Hold for five seconds.  Repeat both five times.

Shoulder stretch – Stand up and place your arms at your sides.  “Shrug” your shoulders up towards your ears.  Now slowly roll the shoulders back, stretch them down and roll the shoulders forward again.  Repeat five times.

Maintaining an ergonomic office is more than just an excuse to buy cool looking furniture, it is actually the key to better health for everyone on the job.  Work environments that are not properly thought out from an ergonomic perspective have been found to cause a variety of ailments, including: carpal tunnel syndrome, eye strain, headaches and back pain.

There are a variety of ways to improve the ergonomic standing of an office, from positioning furniture correctly to improving the lighting and ventilation around the workspace.  The following are ten tips and tricks for making your office ergonomically correct - whether you’ve got one employee or one thousand.

10 Tips for maintaining an ergonomic office

1. If your feet don’t touch the floor, always use a foot rest. Providing a simple, adjustable foot rest at every workstation will help employees maintain a strong back and avoid leg cramps or stiffness.
2. Keep all PC monitors straight ahead and at eye level. If you have to crane your neck up, down or to the side in order to get a good look at your monitor, you will pay the price over time.  Keep the viewing screen level with the direct field of vision to help erase unwanted movements that can cause long-term injury.
3. Use large-barrel pens and pencils. It may sound silly, but trying to grip thin writing instruments all day can lead to cramping and even Carpal Tunnel Syndrome.  Stock your office supply cabinets with pens and pencils that sport a half-inch diameter or greater.
4. Reduce glare throughout the office. Align your desks and workstations so that the office lighting system does not emit heavy glare on computer screens.  Proper lighting is an often overlooked aspect of ergonomic design, yet can improve worker health significantly.
5. Don’t sit under a vent. Proper ventilation plays an important role in ergonomics and good health.  Never place desks or workstations directly in the path of a heating or air-conditioning ventilation system.
6. Design with good air circulation in mind. If there is an opportunity to place workstations close to a natural breeze or well-circulated area, do it!  This can improve worker health and well-being significantly.  The more fresh air that is available in the workplace, the lesser the impact of dust mites, mold and other potentially dangerous allergens.
7. Take short breaks throughout the day.  Many studies have shown that shifting position or changing tasks occasionally throughout the day will lessen the discomfort associated with repetitive tasks.  Something as simple as a two or three minute “micro-break” every hour can be a boon to the ergonomic health of the staff.
8. Exercise during your micro-breaks. Make sure that the time you spend in between tasks is put to good use with proper office exercises.  These simple stretching exercises are designed to reduce to the chance of carpal tunnel syndrome or other repetitive stress disorders.
9. Use adjustable chairs.  For individuals who work on the PC for many hours at a time, chairs with an adjustable arm rest are recommended.  Reaching for the mouse thousands of time throughout the day can cause great arm and wrist strain if the height of the chair is not properly optimized.
10. Get the proper back support for every chair. Finally, the most important element in ergonomic seating is proper back support.  It is highly recommended that you purchase only ergonomically-approved chairs for your office, or if you are on a tight budget, add back supports to existing office chairs.
