Preliminary Study of Wide Base-of-Support Footwear in Preventing Falls Caused by Lateral Slip during Walking
The present preliminary study examined whether an increase in the lateral width of footwear (base-of-support width) can reduce the risk of falling caused by induced lateral slip while turning on slippery surfaces. Wide base-of-support (BOS) footwear was designed and manufactured, with lateral wideni...
