Description
Naoto Izumi, Takashi Yoshida, Toshiaki Nishi, Kei Masani, and Takeshi Yamaguchi use a computer model of walking to ask how floor friction and aging gait interact to cause falls. They built three self-organized neuromusculoskeletal models: a young adult, an elderly non-faller, and an elderly faller. Each was then walked across surfaces whose friction ranged from very slippery to very grippy.
On slippery ground all three models slipped and fell, the elderly faller worst, because its short stride demanded more friction while its foot barely cleared the floor. On high-friction ground only the elderly faller tripped and fell forward, as its stability margin shrank and the swinging toe caught. The results imply an optimal friction window rather than a simple 'more grip is better,' a point the authors say should inform shoe and floor design for older people.
