Noisy Electrical Vestibular Stimulation for Balance in Older Adults

This trial explores whether a gentle electrical treatment can improve balance when combined with an exercise program for older adults. The treatment, known as noisy electrical vestibular stimulation (nEVS), uses small electrical currents delivered through electrodes placed behind the ears and on the neck. Participants will be divided into two groups: one receiving active nEVS and the other receiving a sham treatment, which feels the same but doesn't deliver any current. The trial is suitable for adults aged 60 and older who can attend exercise classes and stand with their feet together for a minute. The main goal is to determine if this treatment improves balance, walking, and overall physical function. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could enhance balance and physical function in older adults.

Research has shown that noisy electrical vestibular stimulation (nEVS) is generally safe and well-tolerated by older adults. Studies have found that this treatment can improve balance in elderly people without causing serious side effects. For instance, one study discovered that nEVS improved balance while standing, and these benefits lasted for several hours after the treatment. This indicates that the treatment is not only effective but also safe for older adults, with no major negative effects reported.¹²³⁴⁵

Most treatments for balance issues in older adults focus on exercises or medications to manage symptoms. However, noisy electrical vestibular stimulation (nEVS) works differently by using gentle electrical signals to stimulate the vestibular system, which helps control balance and spatial orientation. This method is unique because it may enhance balance without the need for drugs, offering a non-invasive and potentially safer option. Researchers are excited about nEVS as it could provide a new way to improve balance and reduce fall risk in older adults, potentially leading to better quality of life.

Research has shown that noisy electrical vestibular stimulation (nEVS) might improve balance in older adults. Several studies have found that nEVS can enhance stability, helping to prevent falls. This trial will compare active subthreshold stochastic electrical vestibular stimulation with a sham version. The active treatment sends small electrical currents behind the ears, aiding the body's interpretation of balance signals. Evidence suggests that nEVS is safe and could lead to lasting improvements in balance. Overall, nEVS appears to be a promising approach to addressing age-related balance issues.⁶⁷⁸⁹¹⁰
