RSI

=The Learning Hubs Health & safety, Repetitive Strain Injury=

RSI is not a new phenomenon brought about by technology, but one that can occur as a result of overuse of limbs in any environment, for example ‘tennis elbow’. We do however have to look at how technology has contributed to RSI’s, how best we can prevent it, and how best to relay this to the pupils.
 * Repetitive Strain Injury**

The main RSI’s associated with computer usage are neck strain and hand and wrist strains, which occur through bad posture and continual use of a keyboard and mouse. As the name suggests RSI’s occur due to repetitive activities and in the case of computers, this is usually sitting typing for prolonged periods of time (without adequate breaks), whilst transfixed to a static monitor or laptop screen. One of the benefits of using a handheld device means is that it is truly mobile which permits alteration of body posture allowing different muscles to be used. In addition to greater mobility, the school environment and daily routine does not lend itself to those typically associated with RSI’s, for example:
 * Short periods with breaks in between, ensure the activities in the school are not prolonged
 * Interaction with teachers and peers during the class encouragesmovement and activity which lessens the likelihood of continual prolonged repetitive movements.

Posture is of course a consideration, just as we do not wish our children to be hunched over a book or a desk, we do not wish them to be bent over looking at a computer screen. Similarly overuse of a stylus is similar to the overuse of a pen or pencil which can lead to symptoms akin to ‘writer’s cramp’ which is itself, a form of RSI. The principles are the same and we need to observe how the children interact with the technology and we will react and advise accordingly.

Also in this instance we must also consider eye strain on small screens.
