Current research conclusively proves that short, frequent micro-breaks accompanied by some physical activity during the work day significantly reduce the rate and risk of computer injuries and
Repetitive Strain injury (
RSI). These breaks also contribute substantially to productivity. The 5 minute movement exercises developed by Desk-Trainer not only provide a break with some physical activity, but also provide immediate transformation from old, limiting neuro-muscular patterns into effective pain-free ways of sitting and moving, thus
preventing carpal tunnel syndrome.
A Cornell University press release (Sept. 24, 1999) stated: "When workers heed the computer's reminder to take a break, their productivity jumps." Workers who used computer software to remind them occasionally to assume good posture, take short breaks and occasionally stretch, do more accurate work and as a result are more productive, according to a new Cornell University study (Prof. Alan Hedge - Director of Cornell's Human Factor and Ergonomics Faculty).
In his study, Hedge found that workers receiving the alerts were 13% more accurate on average in their work than coworkers who were not reminded. The improvement in work accuracy reflects an overall 1% jump in worker's total productivity during the 5 week test period.
"
The results are conclusive. People can measurably improve their computer productivity and substantially reduce their risk of Repetitive Stress Injury if they would simply work smarter", Hedge says.
Research has been published in The international journal of Industrial Ergonomics Design on work/rest schedules for computer work based on psychophysiological recovery measures (Wolfram Boucsein, Michael Thum 1997). The report says in the abstract: "Short breaks (micro-breaks) were more effective in promoting recovery from both mental and emotional strain until the early afternoon..." and "recovery from muscular strain was treated during scheduled rest breaks compared to unpredictable breaks such as system breakdowns"
Deborah Quilter in her article "Ten resolutions every computer user should make" (published January 6, 1998) recommends: "take regular, frequent breaks. Sustained, repetitive computer work fatigues the muscles in the hand and forearm. Overuse can lead to micro-tears in the soft tissues, which can become swollen and painful. Swelling can lead to pressure on the nerves and conditions like carpal tunnel syndrome. Repetitive movements can also damage tendons. If you don't take adequate rest, injured tendon fibers can't heal and thus may be permanently weakened".
"Breaks and rest allow the body to repair itself; nonstop work perpetuates the damage. If you wait until you're in pain to adjust your work habits, it'll be too late.
Stay in peak physical condition. Computing is an athletic activity, and whether you like it or not, you should be in shape for it".
