What's Best - Handwriting or Typing?

A few years ago, I conducted an Ergonomic Workstation Assessment for an adult who was employed in an administrative role. This particular employee had the task of completing a large number of forms by hand and she was experiencing symptoms that her GP thought might be early signs of Carpal Tunnel Syndrome. This recent assessment again got me thinking about writing.

Computers and other electronic devices are being used more frequently to communicate - either in real time or to convey a story or recount an experience. It appears as though typing has become the preferred method of communicating over writing and even at times over speaking. I wonder if this is the reason why there is an increasing number of both kids and adults who struggle with writing - either by writing poorly or by developing pain in their hands and wrists during this task?

It's important with any skill to practice often. Use it or you lose it - basically. My approach with working with kids is to firstly correct their pencil grasp, and then practice, practice, practice. Work on letter formation, letter height, width and word spacing. With adults who are reporting pain or other symptoms e.g tingling in the hands, I encourage them to continue writing, but to alternate written tasks with other activities. I encourage all clients, both young and old, to perform hand stretches before commencing writing tasks - just like a footy player would stretch his muscles before running onto the field.

I would love some feedback on this post. Which is more important - handwriting or keyboard skills? Do you experience hand or wrist pain if writing? What about your kids?

Please note, if you experience pain, numbness or tingling when writing or typing, and it does not go away, seek medical attention.

Healthy Home Office Habits

If you work from home, chances are you have or will experience musculoskeletal pain.

 

Remember back in the 80's there was an epidemic of RSI (Repetitive Strain Injury)? You may at least, have heard of the term. The sudden increase in RSI cases coincided with the increased number of computers being used by office workers.

Following this, workplaces began to focus more on strategies to prevent the onset of injury related to constant computer use. Most workplaces now have training or other methods of ensuring their workers are aware of safe work practices and ergonomic principles. Unfortunately, most of us employ these principles at work, and then forget all about them at home!

There is a fantastic cartoon called the Evolution of Man that depicts a hunched over Neanderthal man evolving into modern upright man, and then over time becomes a man hunched over a computer – mimicking the posture of the earlier man. It's a cartoon that is often shown to us Occupational Therapists as students. It is humorous, but illustrates one of the reasons why so many people now report back, neck, and wrist pain.

An insightful client once pointed out to me that humans weren't designed to sit for long periods of time working on a computer. This is true. The largest muscle groups are in the lower limbs, to help us move around. Prolonged sitting, particularly with using a computer, can lead to fatigue of the smaller muscle groups, and eventually pain and injury.

Most offices now, are equipped with fully adjustable, ergonomic chairs and sometimes height adjustable desks. Monitors can be moved to an appropriate height, angle and viewing distance and screen settings can be adjusted to suit varying visual deficits. People who spend a lot of time on the phone often use headsets or the loudspeaker function, freeing their hands for note taking.

Then there's the whole range of ergonomic mouses, track balls, keyboards with wrist rests... the list goes on. Interestingly, workers still report symptoms of pain that are later diagnosed as Occupational Overuse Syndrome (OOS), or RSI.

One reason is that ergonomic and adaptive equipment may be in place, but used incorrectly. Another reason is that stress is contributing to muscle tension and/ or the worker is not taking enough rest or posture breakers. And the reason that applies to most of us – we don't apply preventative strategies at home.

Many of you are now working from home and trying to squeeze in computer time around meeting the needs of your families. Laptop computers, blackberries, iPhones and other electronics have made it easy to work while sitting on the couch, on the floor or even in bed. Unfortunately, safe work practices go completely out the window.

 The ideal working position is this:

·      knees, hips and elbows at a 90 degree angle when seated

·      feet flat and touching the floor

·      spine supported to maintain the natural curves

·      the monitor or screen height should be at eye level or just below

·      the keyboard should not be higher than your wrists, when your elbows are kept    at a 90 degree angle

·      Your wrists should be neutral (flat)

·      Your mouse, phone or other frequently used items should be within arms reach.

 In addition to the above, you should not be seated for longer than 20 to 30 minutes at a time. Go and grab a coffee or throw yourself on the floor with the kids, but don't stay seated for too long. Even if you are sitting in the position described above, your muscles will still fatigue and injury can result.

So what now? Find somewhere in your home to set up a workstation that allows you to adopt healthier work habits. If you must sit on the couch or in bed, make sure your back is well supported and you adhere to as many of the above points as you can. If you are still experiencing pain, numbness and/or tingling anywhere (except the good places!) see your doctor. It is also possible to consult with an Occupational Therapist (OT) who works in the area of vocational rehabilitation or ergonomics.

An OT can visit your home or office, assess your individual work needs, and provide you with advice, strategies and equipment recommendations if relevant. If you have employees, this is a good idea as a preventative measure to avoid expensive workers compensation claims.
