Here is a great article on fall injuries:
A fall is defined as “an unintentional loss of balance that leads to failure of postural stability”. Approximately one in three adults over age 65 fall every year, often resulting in injuries that include wrist fractures, hip fractures, or head-trauma. A fall injury can cause a significant burden on your family and can increase your odds of ending up in a nursing home by 10 times!
In older adults, falls are the number one cause of admission to the hospital and accidental death. Even the fear of falling again can make people restrict their activities, thinking that they’re reducing their risk, but that de-conditioning may actually increase fall risk.
