Fall Detection in Medical Alert Systems
Fall detection is a feature found in many medical alert devices that allows the device to notify a monitoring center if it detects the user has fallen. The monitoring center will then dispatch an emergency response unit to the location of the user, or will call a family member or friend on their behalf.
Most medical alert devices with fall detection use an accelerometer, a sensor that measures changes in motion. The sensor sends this data to a computer chip, which then analyses it according to an algorithm. The algorithm is usually designed to determine whether the movement has reached a threshold indicative of a fall. It is also common for these devices to have a manual call button that the user can press in case the system fails to detect a fall.
While this technology has proven to be effective, it is important to remember that no medical alert device is 100% accurate. This is especially true for those who have a low balance, such as people with Parkinson's disease, multiple sclerosis, or congestive heart failure. These conditions can cause dizziness, loss of balance, or even unconsciousness. These users are more likely to suffer serious injuries from falls than those without such conditions.
Several different strategies have been used in the field of fall detection, including motion sensors, IoT (Internet of Things) technology, and machine learning (ML). A recent review of these technologies found that they have an average accuracy rate of approximately 80%. The authors of this review note that more research is needed to improve the accuracy of these systems, particularly those using ML.
personal alarm In addition to improving the accuracy of fall detection, a number of companies are working on ways to improve the usability of medical alert devices. This includes developing smaller, more portable sensors and adding features that allow the user to self-report a fall when it occurs.
personal alert safety system device Medical alert systems with a mobile component are becoming increasingly popular, as they offer the ability to go wherever the user does. This makes them ideal for individuals who live alone, and those with chronic medical conditions that could put them at risk of falling, such as Alzheimer's disease or dementia, diabetes, Parkinson's disease, or seizures.
These systems include a small, lightweight device that connects to a cellular network. Most have a pendant with a call button that the user can press in the event of a fall or other health-related emergency. Some mobile medical alert systems also allow the user to contact a customer service representative through a two-way speaker, for additional assistance. These systems are often offered at a lower cost than home-based medical alert systems. Some offer AARP discounts, and others offer special pricing for veterans or seniors. These prices can range from less than $15 per month to $60 or more per month, depending on the equipment costs and contract requirements.
