AI Fall Detection Systems For Seniors
Fall detection systems use sensors, algorithms, and communication devices to identify and respond to falls that have already occurred. When a fall occurs, the system triggers alerts to notify caregivers or emergency services. Wearable devices like smartwatches analyze motion data to determine if a fall has happened. Additional sensors such as heart rate monitors or video can provide more context of the fall. AI and machine learning advancements have improved accuracy by distinguishing between falls and normal activities.
Non-wearable sensors such as video cameras use artificial intelligence that is trained to recognize the difference between, let's say, a rug that is shaped like a human on the floor as opposed to an actual human that is on the floor.
These algorithms are smart and trained to recognize three dimensions (length, width, depth) from two-dimensional sensor information. Sensor information can come from various electronics such as video, lasers, thermal, and sound systems to look for changes in these signals over a period of time that indicate a person is falling or has fallen. More details about fall detection devices can be found here.
Fall detection systems for seniors have their advantages and disadvantages. Here are the pros and cons of using fall detection systems:
Pros:

Additionally, not all seniors may be comfortable or familiar with using technology, making adoption challenging for certain individuals.
It's important to note that fall detection systems should be seen as complementary to, rather than a replacement for, regular care and monitoring by caregivers or healthcare professionals. These systems can provide an additional layer of safety, but human intervention and support remain crucial in ensuring the overall well-being of seniors.
AI Fall Risk Assessment as an Intervention Strategy
Each individual's fall risk is influenced by various factors such as age, gender, socio-economic status, education, health, medication, and emotional well-being, with the risk fluctuating throughout the day based on dietary intake.
Traditional methods of assessing fall risk have relied on manual evaluations, including paper-based assessments like the Mohr Fall Risk Assessment and the Johns Hopkins Fall Risk Assessment, as well as labor-intensive tests of strength, balance, and gait such as the Time UP and Go (TUG), 30-second chair stand test, and 4-stage balance test.
However, these manual evaluation methods have drawbacks that can be overcome by leveraging AI technology. Manual assessments are time-consuming and labor-intensive, limiting their efficiency. Moreover, they rely on a limited number of data points, potentially missing subtle changes or underlying factors that contribute to fall risk. Human observations may not capture all the relevant details necessary for an accurate assessment, often overlooking gait abnormalities, balance issues, or subtle movement patterns.
In contrast, AI-based solutions have the potential to provide a more comprehensive evaluation by analyzing a broader range of data, identifying patterns, and detecting subtle indicators of fall risk. This can lead to a more accurate assessment and better prevention strategies for addressing fall risks in seniors.
With advancements in technology, there are now artificial intelligence-driven tools that take the manual aspect of these tests and automate the evaluation of the tests. Furthermore, it uses the growing database of the results of these tests along with the individual’s medical history and other health-related data to determine if an individual is likely to fall in, let’s say, within 90 days.
Such high-fidelity personalized information simplifies the process. Amid the nationwide and global shortage of care workers, the AI-driven tools to assess fall risks specific to the individual and efficiently create care plans can positively impact operational efficiency and health outcomes of our seniors in nursing homes.
The availability of these AI-based tools is growing. In 2022, researchers at The University of Pittsburgh, Stanford, and the University of Toronto found that their AI-trained model could identify with 99% accuracy that an individual would fall within three months of emergency department discharge. I spoke with Dr. Ervin Sejdic, one of the researchers, said:
“This is a growing area of need, and findings from our study are critical to build a scientific evidence base for tools to identify older adults being discharged from the ED to home who could benefit from interventions to reduce falls and related injuries.”

Additionally, AI i analyzes neuroimaging data like MRI scans to identify brain patterns and predict the risk of conditions like Alzheimer's disease. By leveraging machine learning and large datasets, AI enables accurate detection, continuous monitoring, and personalized risk assessment of cognitive decline, leading to better interventions and care for older adults.
The Transformative Impact of AI In Eldercare
When supplemented with human intelligence and action, the use of AI systems in health care can provide advantages in three key areas:
- Improves speed, capacity, consistency, and accuracy:
Computers don’t forget what they have learned, don’t get tired, and can recognize shifts or patterns in data more quickly and comprehensively than most humans (once they are trained appropriately). Automation and AI can run thousands of tasks at once – something impossible for humans alone to achieve.
- Addresses the increased amount of data:
Healthcare experts (no matter how experienced) can only take in, comprehend, and act on so much data at one time, and in health care, the breadth and depth of data are growing exponentially. AI can help process the rapidly expanding amount of structured and unstructured data from sensors, medical devices, mobile apps, and EHRs to make data more actionable.
- Enhances the abilities and efforts of human workers:
AI can help free human experts from repetitive or tedious tasks, continuously monitor complex situations, discover patterns and anomalies, and ensure that tasks do not fall through the cracks. AI can be a trusted and capable assistant, augmenting human capabilities across the value chain.
With these key benefits in mind, AI can take on various potential use cases within health care, including research, education and training, clinical decision-making, patient engagement, and business operations.
