Forty-five percent of students reported
discomfort at the beginning of the computer class
and 80% reported discomfort at the end of the
computer class (Fig. 2).
The mean level of discomfort increased from 2.6 at the beginning of the class to 3 at the end.
This increase in reported frequency and intensity of discomfort might have been caused by the use of computers during the class.
This suggestion is supported by the work of Jacobs and Baker who found that between 22.7%
and 54.5% of students felt that using a computer worsened their pain. It is interesting and quite worrying to find such high levels of baseline reported discomfort.
The high level of reported discomfort at the end of the computer class is also quite worrying as research indicates that when children experience discomfort while using a computer, they are more likely to continue and less likely to report it to adults than children playing sports or musical instruments
