Abstract

The world guidelines for fall prevention outline that 30% of older adults has a fall each year, with half this figure continuing to have more frequent and life changing falls. The impact of falls can lead to increased risk of injury, fractures, pain, prolonged immobility and a difficulty or inabilit...
