Automatic Fall Detection
Automatic fall detection is a feature that is available in medical alert systems and some personal emergency response devices. It uses sensors in the device to detect rapid downward movement that might indicate a fall and then automatically contacts the monitoring center or other trusted contact. This is a great option for people who might have difficulty pushing the help button themselves or who have unavoidable issues with their mobility that prevent them from doing so (like loss of balance, vertigo, or paralysis).

In order to achieve good performance, the algorithms must be trained on real-life data collected from a large number of different falls. This is difficult, however, as acquiring and testing the number of actual falls required to train the system can be cost prohibitive and inconvenient. Many existing studies have used simulated falls and the results of these tests need to be carefully evaluated.
Most wearable devices use accelerometers to sense rapid downward movement. They then trigger an algorithm to detect a possible fall and alert the system and a loved one. Most medical alert devices also include manual help buttons, so that the user can call for assistance if they are not able to activate their automatic fall detection.

The most advanced systems use a built-in three-axis accelerometer, similar to the ones found in many smartphones and smartwatches. They are designed to detect a rapid decrease in acceleration that can be caused by a person falling or if they are attempting to break a fall with their hands.
Some medical alert systems incorporate this feature as part of their monitoring plans while others offer it as an add-on that can be added to the device at any time. Before purchasing a medical alert system with automatic fall detection, be sure to check out the manufacturer’s website and online consumer reviews to learn more about how this technology works. Also, be sure to understand the monthly monitoring subscription fee and contract requirements for the medical alert device you are considering.
In addition to the safety features of fall detection, look for a medical alert system with two-way communication, GPS tracking, and water resistance. This is important if you live in an area with frequent rain or other weather events that could cause your device to become wet. It’s also helpful to have a battery with a long life, so that you are not constantly needing to replace the unit. Daily medication reminders are an additional useful feature for aging adults who struggle to keep track of their pills, as incorrect pill-taking can increase their risk of falling.
