How do Touch-Screen tablet user configurations' tilt,
affect their head and neck flexion angles?
The study was to determine how head and neck postures vary when using tablet
computers in common user configurations.
Conclusion: Head and Neck flexion angles during Tablet use were greater, in general,
than angles previously reported for desktop and notebook computing. Head and Neck
posture during tablet computing can be improved by placing the tablet higher to avoid
low gaze angles (i.e. eye level rather than on the lap) and through the use of a case
that provides optimal viewing angles.
Rise in RSI injuries from clutching and swiping tablet computers
Amy Oliver, Daily Mail, UK Feb 2012
Dubbed 'iPad hand', users have complained of aches and pains in the hand they hold the device with and in their fingers after typing on and swiping the screen. Medics are also treating people for arm and neck problems associated with holding their iPad on their knees. Experts in body posture have identified several risk factors in using Tablets and smart phones. Dr. John Pappas, medical director at the Beaumont Centre for Pain Medicine in Michigan, USA, said: 'Prolonged use of tablet computers can cause different forms of repetitive strain injuries to the fingers and hands. Good posture can help minimize these symptoms.'
Text Neck: Another Health Hazard Caused By Mobile & Tablet Use
Carol Simons March 2012
Chiropractors have dubbed the position, otherwise known as Forward Head Posture (FHP), text neck. The head of an adult weighs 10 to 12 pounds. The way humans are aligned the head is meant to be centered on the neck, the neck acting as a kind of fulcrum to the head. When we keep the head off-center for periods of time, neck muscles have to overcompensate. Keep doing that and the body will eventually form that position permanently, and lead to serious health problems, like arthritis, heart and lung difficulties, and even digestive interference.
