The most common activities being performed at the time of fall-related hip fracture are walking forward and turning around. Although 40% of hip fractures occur during walking and 18% occur during turning. Cumming & Klineberg found that a fall while turning is 7.9 times more likely to result in hip fracture than a fall while walking straight. This evidence suggests that turning is a greater challenge for individuals with mobility problems than is walking straight ahead. Hence, turning carries a significant risk for hip fracture.
