Summary
The purpose of the present study is to analyze the influence of four backpack loading conditions (0, 10, 15 and 20% of body weight) on the electromyographic activity of the neck and lumbar muscles of elementary school children.
Detailed description
Elementary school children participated in the present study, between the ages of 6 and 10. Bilateral sternocleidomastoid, rectus abdominis and erector spinae muscles activity were recorded using surface electromyography (sEMG), while tested for the effect of four randomized backpack loading conditions.
