Who knew backpacks could be so dangerous? Last year, nearly 5,000 trips to the emergency room resulted from backpack use. Chiropractors wanted to minimize those trips and banded together to distribute tips for proper backpack use. Tips apply to everyone, but most are geared toward young students. Dr.Randy Myers says children should only carry 10-percent or less of their body weight, on their back. Because workloads require multitudes of paper and course books, many students are weighted down well beyond the proper percentage of backpack weight. Doctors suggest students purchase ergonomically designed backpacks, choose backpacks with large, thick straps and backpacks that strap around the waist for maximum stability. The Chiropractic Associates of Zanesville will hold free backpack screenings throughout August. Contact their Sunrise Center Drive office for more details.
