Backpacks & back pain

 

SEPTEMBER 7, 2011 Wednesday Spinal Effects of Backpacks Persist After Use 30 minutes after a person takes off a backpack, some of the negative effects on the spine are still present, suggesting a possible reason for backpack-associated persistent neck and back pain, says a team led by Daniel Hung-Kay Chow of Hong Kong Polytechnic University. The study of 13 adults, who walked with—and then without—backpacks that were 10% of their body weights, showed that the backpack-caused forward curvature of the participants' cervical spines hadn't fully recovered a half-hour after the backpacks were removed.
