Researchers at Virginia Tech use innovative technology to gather real-world data on balance loss among older adults.
Researchers at Virginia Tech are pioneering a novel approach to understanding the dynamics of balance loss, a significant risk factor for falls in older adults. Led by Michael Madigan, a professor in the Grado Department of Industrial and Systems Engineering, the study utilizes wrist-worn voice recorders to capture real-time data when participants experience balance loss. This method marks a departure from traditional recall-based research, offering more immediate and accurate insights.
“In the past, researchers would ask participants to recall what they were doing when they lost their balance, but memory can be unreliable,” said Madigan. “With this new method, participants record their experiences immediately after an incident, providing much more accurate and detailed information.”
Key Findings: Real-Time Data on Balance Loss
The findings, published in the Journal of the American Geriatrics Society, demonstrate the value of immediate self-reported data. The study involved 30 participants, with an average age of 72, wearing wrist-worn voice recorders over a three-week period. When they lost their balance, participants turned on the devices and answered key questions about the incident, including:
- When and where the balance loss occurred
- What activity they were engaged in at the time
- Actions taken to regain balance, such as grabbing a railing or taking steps
- Perceived reasons for the loss of balance
- Whether a fall occurred
By recording their reflections immediately, participants were able to provide detailed accounts without the inaccuracies of delayed recollection. “We’re trying to better understand the circumstances in which people lose their balance,” Madigan said. “This process doesn’t require people to think back weeks or months to an incident, especially when memory can be unreliable.”
The Study’s Broader Implications
Neil Alexander, director of the VA Ann Arbor Health Care System GRECC and co-researcher from the University of Michigan Medical School, emphasized the potential of this research to influence fall-prevention strategies. “Understanding not just how, but why people lose their balance is key to developing better interventions,” he noted.
The study’s findings could contribute to developing proactive tools for clinicians to address fall risks before an incident occurs, particularly for older adults at higher risk. By combining this real-world data with lab-based measurements, researchers hope to refine strategies for balance training and fall prevention.
Participant Reflections
Maria Moll, a retired epidemiologist in her 70s and study participant, shared her personal connection to the research. “I’ve always been interested in physical fitness and balance, especially as I age,” said Moll. “This study made me more mindful of my movements, particularly during more challenging activities like hiking.”
Her involvement in the study highlights a growing awareness of the importance of balance and fall prevention among older adults. Moll’s increased mindfulness during everyday activities reflects the broader impact that balance-loss research can have on improving quality of life and reducing fall-related injuries.
Future Directions: Expanding the Study
Madigan and his team plan to expand the study to include larger groups of participants and integrate additional data collection methods. By identifying patterns in real-world balance loss, the researchers aim to equip healthcare providers with tools to intervene before a fall happens.
“We want to give clinicians the tools to intervene before a fall occurs,” said Madigan. “This method can provide more reliable, detailed information that helps us understand not just how people lose their balance, but why.”
As this innovative research moves forward, it holds the promise of improving fall prevention strategies and enhancing the safety and well-being of older adults.
