Here's a complaint or illness caused too long using a laptop. According to a study conducted by a team of Boston University, revealed about 50 percent of college students laptop users often complain of pain after using the computer for an hour.
The study was conducted on 18 million students in 2008. "Disorders of the musculoskeletal system that occur in childhood and young adults need to be a concern as the musculoskeletal system and posture are still developing," said Karen Jacobs, lead researcher and therapist from Boston University. He explained that the pain complaints due to the use of laptops is now often experienced by children in many countries.
In addition to the parents to monitor the duration of the use of laptops, Jacobs also suggested that children are taught to stretch and exercise the muscles in order to prevent disruption in the future posture. The report was launched by the Bureau of Labor Statistics in 2009 found abnormalities of the musculoskeletal (muscles, bones, ligaments, and tendons) reached 29 percent of all accidents in the workplace and cause workers to take sick leave.
According to Jacobs, one of the causes of muscle or joint disorders in children desk laptop users are used are not appropriate. To relieve the pain, he suggested that laptop users use a mouse instead of the trackpad on a laptop. "Using the trackpad makes us to be in an awkward position because the position of the hand through the body, rather than relaxed at your sides," said Jacobs, who had been president of the American Occupational Therapy Association. When using the trackpad, usually a finger, the tendon of the fingers are constantly being widened and cause muscle and joint tension.
In a long time, this discomfort will spread to the shoulders, wrists, and arms. In addition, many people also rest their wrists when using the touch pad. This condition is called contact pressure (contact stress) and will weigh on the wrist muscles, nerves, and blood vessels. "Laptop is actually designed to be used on the desk. Having said that, we should add accessories such as a mouse and keyboard to prevent joint pain," said Jacobs.
From the research that he did, it is known that children who suffer the most painful because of the use of laptops generally children who are not active. "There is a trend of people were physically active less frequently suffer from musculo skeletal disorders. This occurs both in children and adults," said Robin Billespie, ergonomics experts. Just as athletes are required to warm up before going down to the field, Jacobs also advise laptop users to stretch in between using the laptop. "Walking around after using the laptop for two hours is a good start," he said. He also advised to do stretching exercises arms, neck, back, and head every day.
