For older adults who live independently, medical alert systems can provide an additional sense of security in the event of a fall or other emergency. Many newer systems offer automatic fall detection, which uses built-in sensors to recognize sudden movements that may indicate a fall. If a potential fall is detected, the device can contact a monitoring center for assistance, which can be especially valuable if the individual is injured, disoriented, or unable to manually press an emergency button. 
AARP recently evaluated a variety of medical alert systems with fall-detection capabilities, looking at factors such as reliability, response times, ease of use, comfort, GPS tracking, battery life, and overall functionality. Some systems are designed primarily for use around the home, while mobile options can provide protection when users are shopping, exercising, traveling, or otherwise away from home. Depending on the provider and plan selected, automatic fall detection may be included or available for an additional monthly charge.
When comparing medical alert systems, it is important to consider the individual’s lifestyle and specific needs rather than focusing on a single feature. Someone who frequently leaves home, for example, may benefit from a mobile system with GPS location services, while someone who spends most of their time at home may prefer a simpler home-based device. Comfort and ease of use are also important since the effectiveness of any system depends largely on whether the individual consistently wears or carries it.
Although automatic fall detection can provide valuable added protection and peace of mind for older adults and their families, the technology cannot detect every fall. Medical alert devices are therefore best viewed as one component of a broader approach to safety and independent living.
