Abstract (Summary)


Eight hundred eighty-four adolescents (408 females, 476 males, mean age, 14.0 years, standard deviation, 0.2) completed a questionnaire assessing weekly computer use. Habitual spinal posture was assessed by photographic analysis while standing and sitting.

Things I learned


1. The amount of weekly computer use was associated with changes in habitual spinal posture, and these depend on gender. These associations may result from temporary computer postures leading to adaptive neuromusculoskeletal changes. The postural changes also tended to be consistent across sitting & standing, which may imply a greater impact on health

2. It shows that frequent use of computers without observing proper posture may entail health risk & alter developing neuromusculoskeletal systems. Incorrect body posture is a gradual process, it is associated to various habitual body positions that we do e.g. sitting, slouching & standing.

3. Computer use causes significant number of injuries related to posture & positioning. In order to prevent incorrect posture, it is necessary to observe a daily break postural exercises & stretching.


Revolution in technology gives convenience in most of our works, but not necessary free to health risk because sometimes doing nothing is merely hazardous as doing strenuous physical work. As with all health-related issues, it is wise to have a balance diet & exercise.
