Students find backpacks a pain

BOSTON, Sept. 3 (UPI) -- U.S. college students say heavy backpacks can be a very real pain in the neck and back.

Research conducted at Boston University found 85 percent of students reported discomfort and pain associated with backpack usage, the American Occupational Therapy Association said Wednesday in a news release.

Karen Jacobs, former president of the association and a board certified professional ergonomist, said the most common complaints were discomfort in the shoulder, lower back, upper middle back and neck. She recommends a loaded backpack weigh no more than 10 percent to 15 percent of a student's body weight.

"Carry water bottles empty and fill them before class. Carry only what you need and leave the rest in your room," Jacobs said.
