New Research Shows Balance and Stability Problems in Type 1 Diabetes

Maintaining balance involves a complex coordination between three systems: your sense of touch and position (somatosensory input), your vision, and your inner ear (vestibular system). When any of these systems work poorly, balance and stability suffer—and falls become more likely.

Researchers wanted to understand whether diabetes affects these balance systems and, if so, how. They also wondered whether diabetic peripheral neuropathy—nerve damage that can occur with diabetes—plays a role in balance problems.

The study involved 188 participants: 94 people with diabetes (49 with Type 1, 45 with Type 2) and 94 people without diabetes who were matched by age and sex. All participants completed specialized balance tests using Computerized Dynamic Posturography (Bertec), a sensitive tool that measures postural control under different sensory conditions.

People with both Type 1 and Type 2 diabetes performed worse on balance tests than the control group. However, the pattern differed between the two groups. People with Type 1 diabetes had particular difficulty when relying on vision for balance. Both groups struggled in situations that required their inner ear (vestibular) system to maintain balance.

When the researchers tested how quickly people could recover from a balance disturbance, those with diabetes responded more slowly than controls. This delayed response time could increase the risk of falling in real-world situations.

The researchers looked for links between balance problems and other diabetes-related factors, including nerve damage, blood sugar control (measured by HbA1c), weight, and how long someone has had diabetes. They did not find strong connections between these factors and postural control impairments.

This suggests that balance problems in diabetes may involve mechanisms that are separate from the factors typically associated with diabetic complications. In other words, good blood sugar control alone may not prevent these balance difficulties.

Falls are a serious concern for people with diabetes and can lead to significant injury and loss of independence. This study reveals that diabetes affects the sensory and motor systems involved in balance in ways that traditional measurements might miss.

The researchers conclude that advanced balance-testing tools like Computerized Dynamic Posturography could help identify people with diabetes who have greater fall risk. This information could inform the development of targeted fall-prevention programs and rehabilitation strategies tailored to the specific balance problems people with diabetes experience.
